Would you believe... superconductors?

Keseco do seem to be using some words having to do with superconductivity, don't they?

They go on to talk about "rotating electromagnetic waves" being converted to and from "far infrared", and the "crystal structure" of the wire. This is all far too advanced for little old me.

(I bet it does wonders for air and musicality, though.)

OK, yes, superconductivity would save power, if you replaced all of the transmission wires with superconductors (as is, very occasionally, actually done). But whatever Keseco say they're doing, that isn't it. Their gadget connects in parallel with your existing wiring.

(Even if you could magically turn all of the conductors in your home into superconductors, while simultaneously sprinkling everything with the pixie dust it'd need in order to still work with zero conductor resistance, you'd save only a tiny amount. Where electricity is lost as heat in the home, it's almost all meant to be lost as heat, either directly as in a toaster, or indirectly in the course of causing some motor, CPU or loudspeaker to work.)

Oh, and no superconductor yet discovered operates at a temperature above -138 degrees Celsius.

But I'm sure these minor quibbles are all thoroughly dealt with somewhere in Keseco's complicated explanations.

The Keseco devices may have an unusual theory of operation - whatever it is - but in appearance and installation they're pretty standard magic energy savers. You just connect the Keseco device in parallel with your existing wiring in the breaker box, and that's it. Whatever it does, it does it to any combination of devices inside the building, without necessarily even being in there itself, much less being electrically coupled or configured to them in any readily apparent way.

Never mind that, though; you can't argue with success. And Keseco's devices are very successful. Just ask them!

Don't ask anyone actually in the electrical-device-analysis business, though. As is usually the case with these sorts of devices, Keseco does not appear to be in any hurry to do any independent tests of their power-saving claims. Neither are these Enerwise people here in Australia, as far as I can see. The Enerwise site uses terms like "proven" and "the results are in!", but the actual evidence is just the usual wall of testimonials. (I eagerly await the publication of Enerwise's "Big Book Of Brag"! Surely that will be where we'll find the long-awaited independent controlled tests!)

Keseco-slash-Enerwise have, of course, apparently been on the news. And as we all know, they won't let you say something on TV unless it's true.

But wait - Keseco's "Certificate" section has an actual "Test Report"! It's reproduced so small as to be almost illegible, but I managed to decipher it!

It's a RoHS test, that certifies that the Keseco products pass poisonous-chemicals tests. Not that they work.

And then, also in the Certificate section, there's some more paperwork, but in Korean.

(This also seems to be par for the course in the miracle-energy-product world. If there are tests, they'll often be from labs in far-flung parts of the world where they don't speak English, even though they're being used to support claims made for products that're sold in English-speaking countries. Even energy-saver companies that are based in English-speaking countries sometimes, somehow, manage to do this.)

For the squinting-and-translating-Korean convenience of my readers, here are direct links to the largest images available from the Keseco "Test Report" page:

In among the Hangul there's what that looks like a statement that... something... used two-point-something per cent less power after... something else happened. But I'm not sure.

None of it seems in any way connected to Keseco's "guarantee" of a 5% power saving.

The "Performance Report" on keseco.com makes bolder claims, and is another entirely typical document for this sort of outfit. Bare numbers, no info on how the test was controlled, and further silence on the all-important question of whether the tester was on the Keseco payroll or not.

This sort of proof-by-assertion is standard for makers of energy savers, magical mileage-improving fuel additives, magnetic anti-arthritis bracelets, ultrasonic pest repellers, literally-magic "money magnets" and so on. There are hundreds - heck, probably thousands - of companies of this sort, big and professional enough to put together a sales package like Keseco's. But even when these companies manage to get large amounts of money from canny investors, they never, ever do the proper tests that would let them actually prove their claims and take the giant step up to their rightful place high up the Fortune 500 list. Instead, they sell (or attempt to sell) their products one at a time, direct to consumers whose own standards of evidence are satisfied by the testimonials presented.

(Often, there's a hybrid middle level between the company-that-should-do-some-proper-tests and the gullible consumers. That level is occupied by the gullible distributor, who liked the product so much he bought a franchise, but who has not yet realised that there's no good reason to suppose the product really does work.)

Keseco's PDF catalogue, and their "Products info" page, also cheerfully claim "Preventing Harmful Electromagnetic Waves" as a feature of their system. I suppose that means your microwave stops working, too. If mobile phones, by some freak chance, do turn out to be bad for you, I suppose your Keseco box will also suck up all of their emissions.

The site and catalogue also say the Keseco boxes "prevent" static electricity. Somehow. Somewhere. And then the catalogue has a picture of what looks like a molecular model of DNA, and then something about Fermi energy. I'd have been completely convinced if only they'd worked in Bose-Einstein condensates and particles with imaginary mass.

The Keseco catalogue also has a number of examples of another standard marker for this sort of business, Irrelevant Certifications Offered As If They Have Something To Do With Whether The Product Works.

There's a Korean patent! A registered design! A trademark! A corporate insurance policy of some sort! Alleged CMA, CE, ANCE, ISO 9001 and RoHS conformance! None of which means the product bloody works!

(Just to make this clear one more time, because it comes up so very, very, VERY often: The Patent Offices in various countries make no attempt whatsoever to determine whether an idea presented for patenting is actually good for anything at all. You don't even have to provide a working model. There's usually some basic screening to keep out blatant perpetual-motion devices {possibly with a caveat that you can patent such a device, but only if you do bring a working model!}, but that's all. All the patent office cares about is whether the idea is sufficiently different from other things that already exist to be worthy of a patent - and most patent offices are so overworked these days that they don't even do this very well. So despite what thousands of crackpots and swindlers have claimed over lo, these many, many years, there is no connection whatsoever between patentability and functionality.)

I remind you, gentle reader, that all of the wonderful effects Keseco products are supposed to cause are, somehow, created by a box that you just stick in or near the building's breaker box, and wire in parallel with the building's circuits. Whatever those circuits are, and whatever business you're in. It would be entirely churlish to suggest that this is analogous to making a "water saver" that hangs off a T-fitting next to your water meter, thereby impeding or encouraging the water's flow in no way at all. So I won't do that.

I suggest, Andrew, that you just put up with your present electricity bill for another year. By then, either Keseco will be a household name, one of the most profitable corporations in the world, with Nobel Prizes in the pipeline for their engineers... or they'll still be grubbing around with all the other retail sellers of worthless "power saving" talismans.

But oh, dear - the proudly-displayed accreditations in Keseco's catalogue go all the way back to 2004! The site itself has been around since 2002!

(It used to have an awesome flash intro.)

And yet still, no Keseco boxes in every electrical substation. No Keseco boxes the size of Winnebagos hanging off the side of every aluminium smelter. No Nobel Prizes.

I just can't work it out.

(UPDATE: More on the Keseco box.)

Herewith, one of the most pleasing correspondences I've ever had with someone who originally contacted me with bold new scientific ideas.

Usually, such exchanges go kind of like this. This went much better.

Subject: Magnetic healing?

I'm on some kind of similar path as you. In any case, really appreciated your summary of kinds, costs and usage of neodymium magnets.

I came across a guy who explained to me that microbes have a tough time living in changing magnetic fields. Germs, viruses... Perhaps that's one reason exercise is beneficial. The electricity delivered in pulses to muscles, causes pulsing magnetic fields all along the way.

This guy and his pals were making "Thumpers" (maybe spelled differently). They were buying Radio Shack strobe lights, then attaching coils in place of lights, and maintained that pulses of magnetism could cure bacteria deep within the body. His wife, for example, had some sort of deep sinus infection that he'd healed.

I talked long distance to the guy via telephone (back in a day where it made a difference that phones were far apart) and compared notes on power. I asked him to describe the results when he applied his thumper pulses to his television screen... again, this was before flat screens so that you'd wiggle a magnet in front of a computer monitor or TV and it would produce all kinda weird patterns. His thumper was effective within a foot or so. Meanwhile, I was twirling a couple of not all that strong cylindrical magnets two feet from my screen and it was going nuts. My magnets were like the size of a pack of Life Savers. These were suspended from my fingers by a loop of rubber band which I could then twirl. Wind and then it would unwind, kind of thing.

Point is, experiment with infected sores by waving the sore part back and forth by a neo magnet. Or, build a little rubber band twirler and try it out next time you have, say, a toothache. Twirl it by your teeth and see if it kills off the tooth caries.

Tom

My reply:

I don't think it's true that magnetic fields kill microbes. And if the incredibly weak magnetic fields from natural electrical activity in the body made life "tough" for microorganisms, walking past an electric oven would kill all the beneficial flora in your gut.

With regard to the magnetic "thumpers", the big question is, "How do the pulses know good bacteria from bad?"

(It turns out that magnetic "thumpers" are also known as "pulsers", and are quite popular among people who usually also believe that Hulda Clark and/or Royal Rife could actually cure just about everything with their electrical "zappers".)

If sinus infections never went away by themselves, then curing one with some gadget would be impressive. When you're dealing with diseases that do go away by themselves, and don't even have clear endpoints or objectively measurable symptoms, though, it's not a great idea to conclude that whatever you did before the disease went away must have cured it. This sort of uncontrolled test may point you toward a real phenomenon that you can then investigate properly, but all it proves by itself is that whatever you did before the disease went away didn't stop the disease from going away.

The "thumper" idea has the same problems as many other half-baked alternative-medicine theories. Magically targeting bad bacteria while leaving good ones, a simple scientific process with Nobel-Prize-worthy effects that would have been discovered by accident ten thousand times before 1910, et cetera.

Yes, CRT monitors are very sensitive to magnetic fields. Which is good, because otherwise the dot would just sit there in the middle and you'd have to wave the whole monitor around really fast to make an image! (You could, to be pedantic, use oscilloscope-style electrostatic deflection instead of magnetic deflection. But electrostatic deflection can't bend an electron beam nearly as sharply as a magnetic field; a 26-inch electrostatic-CRT TV could easily be six feet deep.)

Magnetic fields affecting electron beams are a real physical effect, discovery of which was an important, and inevitable, part of the development of human knowledge about electromagnetism. William Crookes (of the eponymous radiometer, among other things) probably did the magnetic-deflection trick first, but if he hadn't, someone else would have (and, indeed, did), well before the end of the 19th century.

Magnetic fields of modest strength affecting biological organisms, on the other hand, is a claim frequently made, which could easily be tested in a kitchen with less than a hundred bucks worth of basic scientific equipment, but which has never thus been proved.

(You can set up a pretty respectable molecular biology lab for under $US1000, these days. Praise eBay!)

If you walk through a really monstrous magnetic field - the kind with big warning signs about not entering the room unless you've ditched every metal object on your person, even if you're willing to sign an affidavit saying that those objects are not ferromagnetic at all - then you're likely to feel funny. Focused and pulsed magnetic fields directed into the brain can also create peculiar effects. Pulsed magnetic fields may even improve healing, though the verdict isn't quite final on that one yet.

But even magnetic fields so powerful that the feeble diamagnetism of water becomes sufficient to levitate living creatures do not, so far as anyone can see, kill so much as one lowly bacterium.

The notion that field strengths that aren't sufficient to rip a belt buckle clean through the leather could somehow kill germs is, thus, exceedingly difficult to defend.

I cordially invite you to set up some Petri dishes and conduct your suggested tooth-decay experiment. You may be the one who makes the breakthrough!

Tom replied:

I appreciate your thorough and helpful reply. However, I'm not coming from any place of proof. Just suggesting a possibility. As to selectively killing bad flora, that idea never entered my head. The point is that possibly there's something in the idea to consider rather than criticize.

As to a notion you seem to entertain I'll paraphrase as, "If that idea was any good, it would already have been invented". This is a very discouraging idea. The fact is, that in 1850 a bill was put before Congress to close the Patent Office because they thought everything of worth had already been invented. Wrong. Looking back from say the year 3000 we'll see that relatively little had been discovered by 2010.

As to the use of alternating magnetic fields as a deterrent to bacterial buildup (good or bad), I'd be willing to bet that in the not too distant future, it will be determined that the relatively strong magnetic fields used for MRI are curative of certain chronic disorders.

As a youth, my mother told me repeatedly that my ideas were probably already thought of. However, in 1971 I thought up something called the boogie board, and created its manufacturing process. 20-50 million of them have since been built.

Anyhow, best wishes.
Tom

Thanks for not flying off the handle over my typically "thorough and helpful reply" :-).

You may not be "coming from any place of proof", but neither is anybody who's postulating some new scientific claim.

I've explained why the "possibility" you mention is extremely implausible. It would be easy to test, people have tested similar claims many times, and as far as I know, it's never panned out. People have incidentally tested these claims countless times, actually; any time germs and a magnetic field are together and someone checks on the germs later, that's a test of your claim.

I mean, just to pick one example, "magnetic stirrers" are a normal piece of lab equipment. A rotating magnetic field from below a container spins a little stirring rod inside the container. Such stirrers are used in biology labs, and have been for decades. To my knowledge, no germicidal properties from the magnetic field have ever been noticed.

And, again, this'd be Nobel-Prize material. Even if you can only kill germs on inanimate objects by subjecting them to magnetic fields, that'd be a billion-dollar discovery. It'd be a wonderful alternative to autoclaving and chemical disinfectants.

So sure, possibly there's something in the idea. Possibly, Elvis is alive, and currently serving as Emperor of All the Underground Cities of Mars!

[UPDATE: Magnetotactic bacteria actually do respond to magnetic fields, and can in practice be manipulated to do strange things under magnetic control. This doesn't have anything to do with disease control, though.]

On top of the fact that this idea has been tested zillions of times - mainly accidentally, but I'm sure also deliberately; the idea that magnetism is somehow therapeutic is an old one - I've also explained why your friends with the magnetic strobe-circuit doodads are making inconsistent claims in the first place. Somehow, the magnetic fields kill "bad" bacteria while leaving the "good" ones alive.

The magnetism obviously doesn't kill the good bacteria, because otherwise anybody who passed through a strong magnetic field - or used one of these "thumper" things, in case it's field gradient or pulse frequency or something that's critical, not just field strength - would develop the same diarrhoea you get if antibiotics kill off your gut flora.

If you managed to confine the field to your armpits, though, it'd cure underarm odour!

There are quite a lot of beasties that live in and on the human body, more than a few of which would cause obvious effects if you killed them all off. And yet people who spend their whole working life right next to giant superconducting magnets, and people who work in magnet factories, and people who work next to the giant busbars in power stations and blast furnaces, do not exhibit any signs of loss of bacteria. (I'm also willing to bet that if you swab the bus bars, the surfaces of the magnets, et cetera, and culture what you find, there won't be any fewer, or any different species, of microorganisms than you'd expect.)

See also, for instance, people who believe that "colloidal silver" is some sort of cure-all. In that case they've at least got some factual basis for their claims; metallic silver has real antiseptic properties. But they go from that to saying that tiny silver particles (or concoctions that they just allege contain tiny silver particles...) will, if you drink them, be Good For What Ails You, and magically not kill any good bacteria. Which is the point where they and empirical evidence part company, and also the point where they stop making even logical sense.

David Hume's famous statement that "A wise man proportions his belief to the evidence" does not mean that everybody should shut up and just believe whatever scientific orthodoxy, or the government, or some church, says. You're allowed to seek your own evidence, and to judge what evidence presented by others is plausible. You don't need a diploma to be a scientist. A scientist is just someone who does science.

But this doesn't make all claims plausible, or worthy of investigation. Life's too short to follow up on every possibility, no matter how unlikely.

Regarding the "bill to close the Patent Office" - now, see, that's not true either!

This urban legend is usually presented as "a US Patent Office guy in the 19th Century said that everything that could be invented already had been". The version of the story that says it was a Bill to close the patent office also exists in numerous versions. Nobody can decide what year this was supposed to have happened!

Sure, maybe in the future we'll look back on our skepticism about therapeutic magnetism and wonder how we could ever have been so wrong. But nobody's noticed any germ-killing effects yet, though. And lot of people have had MRIs. And most of those people have been sick.

Scientists all over the world are combing through every possible statistical source to find something publishable. A correlation between people having MRIs and infections clearing up would be a brilliant one. No luck so far, though.

I think the relevant saying is "it's good to have an open mind, but not so open that your brain falls out".

Regarding your mother's incorrect assumption that your ideas probably weren't new - indeed, the man who says it can't be done should not interrupt the man who is busy doing it. But this does not mean that the man who says it can't be done is the one who has to put up or shut up!

I'm reminded of this:

Small child: "My mummy says when I grow up, I can be anything I want to be!"
Adult: "What do you want to be, then?"
Small child: "I'm going to be a GIRAFFE!"

You might not actually choose to dash the child's hopes at the time, but you can still be pretty sure that kid's not going to grow up to be a giraffe, a fire engine, a jumbo jet, et cetera. This certainty does not make you close-minded.

However, in 1971 I thought up something called the boogie board and created its manufacturing process.

Wait - you're "the" Tom Morey?! Awesome! If you were here in person I'd ask for an autograph!

(This still doesn't make you exempt from having to prove your scientific claims, though!)

I should have known I was talking with an engineer :-). Take care that you don't come down with "Engineers' Disease", though - the tendency for people with a high level of technical knowledge to decide that their knowledge must be applicable to specialised fields that they don't actually know a lot about. The world teems with distinguished engineers who're spending their later years in futile pursuit of perpetual motion, antigravity, cure-alls and so on.

Now, just because someone is an engineer, and now thinks they're onto something big that isn't quite in their area of expertise, doesn't mean they're wasting their time. But this does seem to be a common failure mode for human minds, and I shudder to think how much hard work has been ploughed into these sorts of hopeless pursuits.

Tom replied:

Dan,
Thank you for all the kind attention. You've developed a very thorough and convincing mind.

Interestingly, you hit quite a few nails on the head. Example: Yes... at age 75 now, having dabbled in way many things, more recently I've made up my alleged mind to spend the rest of my days of developing practical transatmospheric "flight" for the common man. Although I'm making progress and excitedly so, I certainly could be pissing into a windmill or whatever the phrase is. Then again, what FUN!

Health and healing...? About all I've really figured out so far is that not smoking, not drinking, plus getting into the ocean more often than not, exposing myself to ONLY moderate exercise and yet semi-regular doses of cold water shower finishes... has kept me fairly healthy.

Even so, right now I feel like the second half of the avocado that was perfect a couple of days ago when you ate the first perfectly flavored and textured half; then put this second half in the fridge. Now, spoon in hand, ready to dive in... fridge door still open and, "Hey! Where did those stringy things come from"?

Your arguments about all the folks who are regularly working with magnets, stirring fluids in labs etc, were very thought provoking. Thank you.

The whole topic reminds me of a curious event a few years back when our apartment was inundated by ants. In fact the suckers were EVERYWHERE for blocks around; no stain or crumb was left un-munched by the buggers. Funny thing was a good many took up residence in, or at least were staying alive in, the microwave oven! I'd swing the door open, stick in a cup of hot water for tea, and notice dozens of ants meandering around in there. Too busy at the time to do away with any of them, I'd simply shut the door, set the timer for two minutes and bzzzzzzzzzzzzzz. Then open the door, take out the boiling hot tea... and damn if they'd changed at all. Still milling around, none of their little feet up in the air.

Go figure?

Anyhow, thanks for your patient ponging of my pings. Aloha, And good bye. Am going off line for the next couple of weeks, So Cal is too cold for the bones. Heading for Cabo to drink in lots of light... roll in the sand and slosh around in the sea.

Tom

The ants survive because they're too small to be affected by the microwaves, which are "micro" by radio-wave standards, but still have a quite large wavelength. That's why you can see into the oven through that perforated metal on the door, without any microwaves getting out. Note that the perforations are similar in size to an ant!

You can actually drill quite a large hole through the metal around a microwave oven, to for instance install a "lipstick" camera, without any radiation escaping.

If you just put the camera inside the oven and turn it on, the camera's electronics will die almost instantly and obvious macroscopic sizzling and sparking will be happening within seconds.

If the camera's on the other side of a hole big enough to stick your finger through, though, it'll be fine.

(Most cockroaches are juuuust big enough for a microwave to fry them, if you give it a little while. The bigger the roach, the more trouble it'll be in.)

See also the magnificent series of Unwise Microwave Oven Experiments by Bill Beaty, who's one of my heroes.

I've microwaved many CDs, but haven't yet done the fantastic beer-bottle stunt!

Does YOUR hamster have The Right Stuff?

When I read that Neil Fraser's Meccano lava-lamp centrifuge only rotated at 42 revolutions per minute, I didn't think it sounded very impressive.

I take that back.

Long word, starts with P, solves all our problems...

A reader writes:

I've just read an article in Popular Science about Sun Catalytix' "artificial photosynthesis" being used to power houses.

Which got me questioning, is it even viable? Using water as an energy source, as you've said previously, involves electrolysis, and the power it can generate won't exceed what was used in the electrolysis process.

He is using sunlight as the energy source, so I guess it's not one of those water-powered-car scams. But wouldn't it be easier if we use batteries to store the electricity from the solar panel?

And where does the photosynthesis comes in?

Please enlighten me here.

Andhika

The photosynthesis is supposed to replace the electrolysis. See, electrolysis is really inefficient, and batteries aren't awesomely efficient either, and you need a pretty darn big battery bank, which wears out, to run a whole house. But photosynthesis can manage efficiency as high as 8%, so... uh...

Look, buddy - "photoelectrochemical cell" is 24 letters - 25, including the space. We're already really pushing the brainpower of the voting public with the word "photosynthesis", all right?

I started doing a series of actual calculations about this, then stopped, because there's not enough information in the article, the marginally-more-informative Scientific American article, or...

...the less-than-entirely-satisfying accompanying video, for any really solid numbers to be made.

(You can't say that that video doesn't alert the viewer to the fact that it's not aimed at people who know a single damn thing about anything. "In the next forty years, you're going to need more energy than is available from every source you can imagine", says actual MIT professor Dan Nocera. Never mind that decreasing human energy consumption, while continuing to improve quality of life, is a real and serious goal; I can also "imagine" fusion power, dude. So clearly I'm not part of this clip's intended audience. Paging Mr Bush; Mr Bush to the coal-fired courtesy phone, please...)

In neither the Popular Science nor the Scientific American piece does the writer seem to have paid any attention to that core "30 square metres of solar cells in Boston making 30 kilowatt-hours in four hours" claim. It seems fishy to me. As does the idea that this magical catalyst is actually a useful breakthrough.

I'd be willing to believe that this was a real, if slightly oversold, option, if it weren't explicitly about a system that you're supposed to install on your roof to run your house. This didn't, early in the Scientific American article, seem to be the case - "We emulated photosynthesis for large-scale storage of solar energy", says Dan Nocera.

And yeah, you might perhaps actually be able to get the stated output from the stated area of cutting-edge panels at Boston's latitude if they're all on expensive sun trackers and/or overpumped by extra reflectors and water-cooled. Which they can be, relatively economically, if they're part of a municipal solar farm and not stuck on someone's roof.

No matter how good the magic catalyst is, though, nothing's going to give you all of those 30 kW/h back again, and Mr Nocera goes on to say "...We need to do it the old American way of making one small one and then manufacturing that system to give it to the masses."

Which brings us back to the cheerful notion of an easy $35,000 worth of cutting-edge solar panels and sun-tracking hardware on everybody's roof, much of which will need repairs after every storm. Unless you ditch the trackers, reflectors, cooling system, et cetera, in which case the stated energy output becomes impossible with even maximum-efficiency commercial solar cells of the stated area. You're likely to need something like twice that area for well-aimed never-shaded cutting-edge commercial cells, an easy three or four times the area for cheaper panels installed on a real-world roof...

A couple of commenters on the articles, and on this Engadget writeup, managed to briefly poke their heads above the SOCIALIST TEA PARTY MASONIC JOHN BIRCH GRR comments to point out some of these issues.

Fortunately, even if Mister Nocera is being outrageously misquoted (occasionally by himself!), his company is only about the hundred-thousandth-worst outfit to have had US taxpayers' money sprinkled upon it lately. And who knows, maybe there's something to this, even if it depends upon solar panels that haven't yet been invented, or something.

I wouldn't rush out to place a deposit, though.

Power factor. Again. I'm sorry.

Regular readers will know that the world currently teems with "power saving" devices, which are alleged to use Power-Factor Correction to save you money on your electricity bill.

These things are absolutely excellent, except for four minor flaws.

One, little plug-in PFC gadgets don't actually correct power factor at all, two, little plug-in PFC gadgets don't actually correct power factor at all, three, domestic electricity customers aren't billed by power factor anyway, and four, domestic electricity customers aren't billed by power factor anyway.

I realise that, technically speaking, that's only two flaws, but I thought they were such big ones they were worth mentioning twice.

At the other end of the commercial spectrum from the BS plug-in power savers, there are big industrial units designed to correct the atrocious power factor of certain particularly serious offenders, like really big electric motors, or really large numbers of smaller motors. Usually these sorts of correction setups are just capacitor and/or inductor banks carefully matched to the load; sometimes they're "smart" devices that adjust themselves to correct varying power factor, which is what you'll get if, for instance, you've got a factory full of big motors that keep changing speed and load.

This sort of PFC, and similarly large-scale PFC that's implemented by the actual power companies (typically in the form of big capacitor banks at substations and other distribution transformers), is entirely genuine, quite useful, and very expensive. But if you're billed by power factor, or if you're a power company that wants to minimise the mass of metal in your whole distribution network, PFC is essential.

In between the little rip-off plastic home-user things and the vast custom capacitor banks in power stations are, as you'd expect, PFC devices for medium-load applications. Yesterday I corresponded briefly with someone who's trying to sell such devices.

Regular readers won't find anything very new and exciting in this correspondence, and I wouldn't blame any reader for only lightly scanning at least the first giant block of quoted text. I'm posting this mainly so that Google searchers will be able to find a little more info about this field in general, and this product in particular.

(Also, I've suffered for my art, so now it's your turn.)

Dan, I was reading your article and wanted to share with you our new technology. I agree with you on a residential level that the current PFC units don't save you money ,but when you take PFC and only put it in the circuit and remove it there is a savings. I am reaching out to all the blogger on the net and am asking them just to consider that what I'm saying is real. We have seen savings and when the product which just went to mass production get here I am reaching out to all bloggers on all continents to get a unit in their hands. I don't want to sell it to you. It will sell its self when you see it work. On the business side the meters do read different here in the states and the savings is much greater. Please take time to read the PDF study and when we hit your continent we can get one installed for your testing.
Why is power factor correction an important part of reducing co2 emissions and is there any new technology available to ad to the global effort? Yes, let me explain where this large void is occurring. Large industrial power users (demand side) have been using power factor correction (pfc) for years on large motor driven equipment because its too costly paying the power providers for this wasted reactive energy (poor p.f.). There is a demand (penalty) charge on their monthly bill including all commercial users. Several companies build PFC units by incorporating capacitors in various amounts to match the loads of running motor(s) to offset this penalty. These units are large and tailored to do a cost saving job for this industry. The user and power provider both see a power usage benefit.

Home and commercial users share the burden of poor power factor and extra power must be provided to offset this waste. Air conditioning, furnace blowers, refrigerators, freezers, washers, dryers, fans, garbage disposals, dishwashers, lighting with ballast or transformers, pool pumps etc all ad to the burden. Whitby Hydro Energy Services of Canada did a series of test in 2005 by taking a group of homes and using pfc devices with a set amount of capacitance. Their conclusion: ‘The result of the pilot indicated that the addition of capacitance indicate that installation of the units on mass will reduce the generation requirements through the province and we recommend that the findings of this pilot be shared with the government officials as a viable means to help address the supply and transmission issues within the province”. The full 15 page PDF report is attached.

[The above quote isn't quite what the report actually says, but it's basically correct. Yes, the report does actually use the term "on mass". Hey, give 'em a break - they're in Ontario. Nobody speaks French there.]

No doubt Whitby Hydro could save on power generation so why not mandate to use pfc units on homes and business and save a new power plant from being constructed? To make this possible a pfc unit would have to turn on and off when motors and ballast/transformer type lighting were operational and make constant capacitance adjustments to correct the different loads and voltage fluctuation drops caused by peek demands. A good pf correction is .95-.96 and going higher can cause frequency modulation problems. Present pfc units are fixed or variable and cannot perform the computerized functions that would be required. This is where Power-CEOtm (Computerized Energy Optimizer) fills this gap. Our patented (USA and most countries) power factor correction units is the first to incorporate the proper technology for global usage. Here is what the patent-holder has to say: “We are confident that our patented “Power-Factor-Correction” technology is light years ahead of the other PFC systems. By and large, most PFC systems are either “Static” (designed for a specific amount) or a hybrid of “Limited Automatic,” designed around several variables and are thus referred to as automatic. However, our power-factor-correction technology is fully and completely Dynamic/Automatic in that it will turn on precisely the amount of correction required in order to attain a PF of .95 and not only that, in the event an additional load turns on or is introduced into the system requiring additional compensation, our Smart System will automatically and instantly adjust to the new required setting. When any load which was requiring the compensation either turns off/on or changes its setting (for example, motors with varying loads), our PFC system will readjust and continue to readjust as needed in order to provide as near to a PF setting of .95 continuously as is feasible.
The current US President, as well as our previous President both stated when talking about the Kyoto Protocol and Copenhagen Meeting on the Environment, that they believe technology will be developed which will help us reach ascertainable goals without significantly hampering commerce. As you will see, Power-CEO™ is one of those technologies.”

Midwest Research Institute, a Government funded institute, has been involved since
2001 helping with technology issues until Power-CEO was completely viable and ready to market, and UL approval has been met. Plamen Doynov the senior engineer from MRI has this to say: I am intrinsically familiar with the technology. I was involved in the development of the original analog implementation during a contract with McDaniel brothers. Consecutively, we performed performance testing of the digital implementation of the technology. A copy of the performance report can be provided. In the report one can see that the testing of the technology confirms that it performs very well as a dynamic power factor correction unit. I am not writing this email as a representative of MRI. As an independent, not-for-profit, contract research institute, MRI has a strict policy not to endorse products, technologies, or cervices. Given an opportunity, MRI has the capacity to test and evaluate very broad technologies and systems. Should you need assistance from MRI in testing, evaluation, or further enhancements of the Power-CEO, I can facilitate the arrangements. Plamen Doynov

Power-CEO is ready for production and can comply to any world specification. Power-CEO is ready to meet the demands of lowering power consumption.

My reply:

I agree with you on a residential level that the current PFC units don't save you money ,but when you take PFC and only put it in the circuit and remove it there is a savings.

I'm not sure what you mean by that. By definition, there's only a saving for people who are billed by power factor, or for people who are in the business of generating and transmitting electricity.

On the business side the meters do read different here in the states and the savings is much greater.

I'm also not sure what you mean by this :-).

There is a demand (penalty) charge on their monthly bill including all commercial users.

Really? How's a "commercial user" defined, then?

The local corner store here is unquestionably a commercial electricity user. I don't think they're billed by power factor.

Home and commercial users share the burden of poor power factor

Yes, in the indirect sense that power in general is made more expensive when electricity utilities have to cope with higher kVA than kW. But no home user will achieve any direct savings by improving their own power factor.

Whitby Hydro Energy Services of Canada did a series of test in 2005

...in which, according to the PDF you attached, they had to install special meters at the homes in order to see any difference, because of course the standard electricity meters do not measure power factor.

Even if all of the houses connected to the tested transformers were directly billed by power factor, though - so if your power factor is 0.9, you pay 1.11 times as much as someone with a PF of 1.0 - the reported improvements in the two transformers with the PFC added would only reduce consumers' power bills by less than 5% and less than 3%, respectively [I averaged out the five tested months in the PDF report].

There'd have to be a penalty rate far in excess of the actual extra volt-amps used to make it attractive to install a PFC system that cost more than a very small amount.

What does your product actually cost? How large would a customer's current power bill need to be to pay your product off in, let's say, five years, assuming it somehow allows that customer to reduce their power bills by even 5%?

No doubt Whitby Hydro could save on power generation so why not mandate to use pfc units on homes and business

Uh, because people don't want to buy expensive things that won't save them, personally, any money :-)?

I am unconvinced that widely-distributed household PFC installations, as opposed to the PFC systems already being installed in electrical substations, are a cost-effective proposition, even if you make them mandatory and have the taxpayer pay for them.

As a "retail" product for voluntary installation by homeowners, they appear to be a total non-starter.

A good pf correction is .95-.96 and going higher can cause frequency modulation problems.

Wait - so now you're saying that the 99.22% and 97.5% five-month average figures from the Whitby Hydro transformer study (versus 94.7% for an unmodified transformer) are undesirable?

The Power Medix device mentioned from page 11 of the PDF you sent apparently went considerably above 96%, as well. I find the figures there rather questionable, though; uncorrected power factor is way down in the .75 to .80 range at night. If that's the result of a water heater or geothermal heat pump or something, clearly that one something is what the power company should be giving that household a free power-factor corrector for, not the whole house.

If your special patented product carefully keeps the PF close to 0.95 at all times, I don't see that there's much of an improvement to be gained. Even if domestic consumers people start being billed by power factor. Which I doubt will happen any time soon, since it's hard enough to even explain what power factor IS to people, much less get them to re-elect someone who took their money because of it :-).

The current US President, as well as our previous President both stated when talking about the Kyoto Protocol and Copenhagen Meeting on the Environment, that they believe technology will be developed which will help us reach ascertainable goals without significantly hampering commerce.

I wouldn't say that in the press release, if I were you. We both know that few-per-cent improvements in power factor are not at all the sort of thing that heads of state are talking about when they make speeches like that.

Your repeated use of the word "patented" as if patents are only awarded for worthwhile inventions seems to me to be another unfortunate tactic.

Power-CEO is ready to meet the demands of lowering power consumption.

Another claim I think you should stop making.

A poor power factor, BY DEFINITION, does not mean that ANY more power is actually being consumed, except for the amount lost to resistance from higher current flows. That's significant for a power company, but vanishingly small for a home user. And even for most industrial users; they only care about PFC if they're billed by power factor.

In reply to this, all Tim sent me was:

Hears a link ,see what the power company has to say.
Also has anybody done a test where every item was corrected in a structure ?

http://www.psnh.com/Energy/ReduceBill_Business/PowerFactor.asp

My reply:

Hears a link ,see what the power company has to say.

That page says:

How correcting power factor can save money
The PSNH demand charge is based upon kva demand for LG customers and upon 80 percent of the kva demand for GV (Commercial and Industrial) customers who have a power factor of less than 80 percent. Power factor correction may offer a savings opportunity for some customers.

"LG" is one of PSNH's "Large Business" tariffs, for "demands in excess of 1,000 KW" (PDF; domestic power consumption is more like 1 to 2 kilowatts, depending on what sort of "average home" you're looking at).

Small businesses are only even possibly affected by these issues if they actually have a low power factor, which outfits that aren't running lots of low-power-factor gear - typically, large motors without PFC capacitors already on them - will not have.

Stores with a huge bank of fluorescent lights may have a lousy enough power factor to be interested by this, but I think modern electronic ballasts have largely solved that problem. The same goes for computers; PCs used to have a pretty consistent 0.7 to 0.8 power factor, which could add up for a whole office full of them, but nowadays most PC PSUs have PFC built in, for exactly this reason.

Also has anybody done a test where every item was corrected in a structure ?

Only if the power factor is actually low enough to make the cost of correction attractive, which in normal domestic situations it is not.

Homes that draw a lot of power often draw it for things like electrical heating, which is almost entirely a simple resistive load with a power factor of 1. And in any case, to say it one more time, no homeowner is going to be interested in PFC if they're not billed by power factor. I am not aware of any nation in which private homes are billed by power factor. You'd think that there'd be some huge housing developments that were billed that way, but if there are, I haven't discovered any.

Since you did not choose to answer my questions, I can only presume that you have no answers for them. Sorry, but I cannot take further time to correspond with you if you're not actually offering anything new.


I don't know what the deal is with people like Tim. He doesn't seem to be deliberately running a scam, but he also keeps saying that products like his are for some reason going to become popular for home and small commercial electricity users. Those users don't actually have any reason to install a power-factor corrector unless they feel philanthropic toward the power company.

And if you do want to do the power company, or the planet, a favour by taking some load off the electricity grid, a much better idea for domestic power consumers is to look into a grid-connected solar system, which can genuinely reduce your power bill.

In many countries, new home solar-power installations are heavily subsidised by the government, for either purchase price, feed-in tariffs, or both. You may also be able to get a subsidy if you install a solar water heater, which is a simpler and less expensive investment than a photovoltaic solar electricity system.

Even if you can get a power-factor corrector for free, though, there's absolutely no point installing it unless you are for some reason using quite a lot of power, with a lousy power factor. Even houses that use a lot of electricity - electric heating in cold climates, big air-conditioners in hot countries, a giant bank of metal-halide lamps in the garage for some reason - don't necessarily have a lousy enough power factor for any add-on PFC to be necessary.

I am super sceptical about Steorn's claims of over-unity, but can you please decipher their latest video?

I can't see anyone showing exactly how it doesn't work, or anyone easily explaining how it does. Can you please devote a blog entry or page to it?

(Just re-read my email – I sound like I'm promoting them, but I am just interested and looking for explanations)

Andrew

Well, I'll devote this blog post to it, but it won't be quite what you asked for!

Until Steorn start handing their devices over to testers that aren't on their payroll, there is nothing to explain. For the same reason, most people don't spend a lot of time analysing the amazing ability of Transcendental Meditators to levitate, turn invisible and walk through walls, because they have never actually demonstrated that they can do these things, in anything remotely like a test that eliminates blatant, basic, wouldn't-fool-a-five-year-old cheating.

I mean, what did Steorn even actually show in that video? Something going round and round, and a man saying that it was an over-unity device? That Hutchison Effect guy seems to have done a lot more presentation work.

Steorn are either about the ten-millionth free-energy scam artists, or about the ten-millionth "free energy pioneers" to fail to correctly measure what's going on, because they don't measure RMS power, mistake voltage for power, put their lopsided antigravity machine on a bathroom scale that can't properly weigh something that's vibrating, et cetera.

(Whenever a perpetual-motion huckster mentions "back EMF", you've got a pretty ironclad guarantee right there that he needs to buy some more expensive multimeters.)

To believe otherwise is to watch Transcendental Meditators bouncing around on their bottoms, and immediately rush to sell all of your Boeing stock.

Don't worry, though. I'm sure all of your questions will be answered with great enthusiasm in an upcoming Discovery Channel special called "The Exciting New Science Of Perpetual Motion"!

Next on Discovery: Alchemy for beginners!

Hey, would you like to see a really dumb piece of science TV?

Sure you would!

Yes, the narrator appears to have no idea what "ironically" means, but never mind that. I find it pretty impressive that the voiceover proudly announces that it will cost nothing to fill up an air car, even as the guy they're interviewing explains that the engine runs on air that has been compressed somehow, and explicitly states that the air is just an energy carrier, not an energy source. (See also "hydrogen wells, nonexistence thereof".)

At the end of the clip, the voiceover grudgingly admits that it will take "some energy" to compress the air... and then immediately boldly postulates an absolutely classic, in-as-many-words perpetual-motion machine, in which the car carries around its own compressed-air-powered air-compressor.

Seriously. That's what he says. In a science show.

That's right - this clip is not from some podunk local news station, or promotional material from some scam artist. It's from an episode of the Discovery Channel's "NextWorld" series.

Which spurs me to ask, "How the fuck did this ever make it to air?"

(As usual, The Onion says it best.)

Setting aside the gibbering idiots who apparently now pass for science journalists in the USA, the vehicle they're talking about is the good old MDI Air Car, which for some years now has been right about to make it to market.

MDI first claimed to be right about to start producing cars in 2000. They've made similar claims several more times over the intervening years. I puzzled over the Air Car in 2006. But no cars have yet rolled off a production line.

Apparently the Tata Motors MDI-powered car will be going into production at the end of this year. I am assured of this.

MDI's most recent technological advancement is to change the name of the Air Car. It's now called Xe Altria FlowAir.

The FlowAir's claimed performance remains highly questionable. It seems that the massive range numbers that MDI have trumpeted these last ten years were arrived at by taking an actual tested range of less than ten kilometres, and applying a bunch of fudge-factor multipliers to take into account the great improvements that MDI promise to make when they actually make a working car.

Oh, and one of the MDI car's big features is that it's supposed to have some sort of heater doodad that boosts the air pressure going into the engine to give long highway range. So in order to get the "200 miles on one tank" the Discovery voiceover guy was so impressed about, you have to burn a fuel to run the heater. Which means that not even the minor claim that the car makes no emissions when driving around is actually true.

But don't worry - I'm sure there's some chemically trivial way to get the heater to run a little machine that makes more heater fuel.

After an idle evening reading the comments section (I know) on the blog of the BBC's US correspondent, Mark Mardell, I came across this ... interesting perspective.

I can answer why electrical power in most of the USA is above ground. The reason is simply in the USA power lines are carrying much more voltage and current than in Great Britain for the most part and travel greater distances. Electricity doesn't simply flow through the wire but on the outside of a wire. The circumference of the wire carries the power if it were underground much of it would be lost in the ground.

Now here is something you don't know. Power companies use different transformers under different conditions. Ever plug in a device and the wire gets warm but other times it doesn't? That happens because when there is a great power demand the power companies try to fool the public that there is adequate power by simply supplying the voltage and the device works.

But this is not what they are telling you. The voltage is there but not the current the device demands in it's productive use of wattage to function. It can't obtain it on the gauge of wire it is designed for and the wire gets hot, homes burn down, lives and possession are lost! Simply because inadequate power is produced. Voltage ratings exist but only because current is decreased. This creates the illusion of adequate electrical power.

I can't identify a single thing in that comment that appears to be true. Am I wrong?

Jonathan

Yes, "KingLeeRoySandersJr" does appear to have a very independent mind. Perhaps he read something about power factor somewhere, and then took further guidance from disembodied voices.

But no, he's not wrong in everything he says. I guess, for instance, that if you were to run un-insulated power lines underground, you probably would lose a lot of power. For analogous reasons, jet fighters without windscreens do not work very well and cars without wheels have disappointing top speeds. Humanity waits patiently for the genius who can unravel these mysteries.

(Fortunately, the extra weight of insulation ceases to be a problem when you no longer have to hang your wires from poles. A lot of people find it surprising that overhead power lines are almost always un-insulated; this often seems to be because they don't know the difference between insulation and shielding. My learned colleagues at Harmonic Energy Products had this problem many years ago, and the confusion also cropped up in connection with this gloriously stupid audiophile power cable.)

The first thing KingLeeRoySandersJr says, about current flowing through "the circumference of the wire", is also not complete nonsense. He's talking, assuming he's got some connection with consensus reality, about the "skin effect", in which the higher the frequency of the AC you're trying to push through a wire, the shallower will be the depth into the wire in which significant current flow occurs. This has to do with eddy currents, which cancel each other out in the middle of the wire but increase current flow on the surface.

Some huge power-transmission lines are DC, which has an infinite skin depth, and some transmission lines for exotic applications - like particle accelerators - run at high frequencies. But changing the frequency of AC is as difficult as changing its voltage is easy, so the vast majority of high-voltage long-distance lines run at the same 50 or 60Hz as the rest of the grid. "Skin depth" - the depth at which current density is one-on-e, or about 37%, of the current density at the surface - at 50Hz is around 9.3mm for pure copper and almost 12mm for pure aluminium, unless the calculations I just did based on Wikipedia's tables of permeability and resistivity are based on subtly vandalised numbers. At 60Hz the depth drops a little, to around 8.5 and 10.9mm, respectively. If you're for some reason shifting 1kHz AC, your skin depth falls to 2.1 and 2.7mm, respectively.

Audiophile nitwits sometimes bang on about skin effect, and pay big bucks for cables with zillions of tiny separately-insulated conductors, maybe woven like Litz wire and maybe just floating around as a cloud, in order to defeat it. The theory is that skin effect increases cable resistance for high frequencies, so you lose treble - or "musicality", or "coherence", or whatever it is they've made up now - if your cables are too fat.

But even if your golden ears have the mystic ability to perceive 40kHz sound, an octave higher than the usual rule-of-thumb 20kHz upper bound for human hearing and higher still than the maybe-14kHz that's the highest most young-ish adults can perceive, skin depth in copper wire will still be around a third of a millimetre at that frequency. This gives plenty of copper to conduct your line-level or speaker-level signals, at all audio frequencies, in just about any cheap cable you care to name, and a resistance difference for 40kHz versus 10Hz of three-fifths of bugger all (a technical term), even if you hook everything up using the now-nearly-proverbial coat-hangers.

(God help me, I just searched for "skin effect" and "digital interconnect" and yes, right there on the first results page are people selling a carbon-fibre RCA cable for digital data that's supposed to be better because, among numerous other brain-hurting explanations, it ain't got no skin effect. It can be yours for a mere $US225!)

Clearly, at normal mains frequencies you need a pretty darn thick conductor before skin effect makes much difference. Big power-transmission cables are pretty darn thick conductors, though, so yes, it affects them. Most aerial power cabling is aluminium (which has higher resistance per unit area than copper, but lower resistance by weight, which is very important for cables strung from towers), but I think it's quite common for those cables to have thin steel wires in the middle to improve their strength. Steel is a pretty terrible power-transmission material, having a skin depth of less than a millimetre at mains frequencies (and yet mild-steel coat-hanger wire keeps passing those blinded audio tests!), but it doesn't matter when skin effect confines most of the current to the outer, aluminium portion of heavy power-transmission cable.
