Can Entropy Be Reversed?

Posted December 12, 2007 8:15 AM

The second law of thermodynamics is taken as absolute by most engineers. Now here's word (once again it seems) of a process that reverses the "inexorable" flow of heat energy in a "compression only" heat pump application.

The preceding article is a "sneak peek" from Hydraulics, a newsletter from GlobalSpec. To stay up-to-date and informed on industry trends, products, and technologies, subscribe to Hydraulics today.

The best way of giving further impetus to this development would appear to be for the inventor to stay well away from Charlotte Douglas International Airport.

That's not the only place he should stay well away from. He should also avoid restaurants in Grove City, Ohio (see article and link below). Oh, and for those of you who believe in flipping the bird to Big Business, the New World Order, the Illuminati or the whoever-else, you can buy the device for $1,500.

Speaking of conspiracies, if no aircraft hit the World Trade Center on 9/11, and that the building was brought down by demolition charges as these conspiracy theory imbeciles claim, then WHY do we have eyewitness videos of aircraft crashing into both towers, and why was there airplane wreckage at Ground Zero?

Will someone please enlighten me on this? It's kind of hard to keep up with the world when you're permanently sealed into a black armored life-support suit.The Water Car (Tells about his murder)
Stan Meyer said he trusted in angels to protect him, but in March 1998, Stan was poisoned and died in the parking lot of a restaurant in his home town of Grove City, Ohio. According to his brother Steve, the U.S. Government came to Stan's home a week after his murder and confiscated his car, which got 100 miles per gallon of water, and they stole all of his research equipment which he had used to develop the new technology.
Stan had been threatened many times and would not sell out to Arab Oil Corp. Stan said he was offered a billion dollars from an Arab to basically shelve his idea but he said, "No, this technology is for the people."Stan said while he was alive, that he was threatened many times and would not sell out to Arab Oil Corp.s The Military was going to use this technology in their tanks, jeeps, etc. He had patents on his invention and was ready for production. Only $1,500 to equip your car! See the Videos above.
Stan made the gas as he drove, no hydrogen tanks, no fuel cells, no need for Shell Hydrogen Stations. He spent 30 years of research all on his own.
So what is happening with Stan's Great Invention of the 20th Century!! Absolutely nothing. Are they manufacturing his invention. NO, Why not? because it would solve all the world's problems today. That is NOT how politics work, MONEY is the ruler here. Common Sense is NOT for humans, only good for OUTLAWS & so called terrorists.? Huh? We live in a time when good is spoken of as evil and evil spoken up as good. Why do I say that because it is true. We were told the US twin towers was taken down by airplanes, when the truth is, it was taken down by C4 explosives. William Rodriguez holds the master key, he was there that day, he lost his job and 250 of his friends and colleges. Connect the dots, it is that simple. Sorry to have shocked you and made your face turn red, but Building #7 came down in 7 seconds, not reported in the 911 commission report. No planes hit that building, only a few offices fires happened

The planes that hit the towers were diversionary aircraft flown by CIA operatives on LSD. The actual (now missing) airplanes were hijacked and flown to the Bermuda Triangle where they were abducted by aliens, except for that one that crashed in the field - it was brought down by Tesla's death ray.

I hope this clears things up for you.

Perseverance!

Edgar A Guest
Someone said it couldn't be done !
But he, with a chuckle, replied,
That "Maybe it couldn't, but he would be one
who wouldn't say so till he tried"
So he buckled right in with a grin on his face
if he worried he hid it
Somebody scoffed "Oh you'll never do that"
At least no one ever has done it
But he took off his coat and he took off his hat
and the first thing we knew he'd begun it.
With a lift of his chin and a bit of a grin
without doubting or "quiddit"
He started to sing as he tackled the thing
That couldn't be done and he did it
There are thousands to tell you it cannot be done
There are thousands to prophesy failure
There are thousands to point out to you, one by one
that dangers will assail you
But just buckle in with a bit of a grin
Then take off your coat and go to it
Just start in to sing as you tackle the thing
That cannot be done, and you'll do it

Every now and then someone comes along with claims of having found Maxwell's demon and ways and means of thwarting the laws of thermodynamics one way or another. The linked articles and references are rife with seems, and other qualifiers just in case they are unable to make the Ammonia Butane Ambient Heat Motor do it's stuff.

The diagram is too muddy to deciper so it is pretty but pretty much useless.

Oh no... not again. Tom Kasmer is mentioned in the article. He lurked here at CR4 for a while (tkasmer) with some outlandish claims for his hydrostatic transmission. Seems he has now truly gone over to the dark side.

Lovely. Actually I have been sad at the recent lack of free energy posts. I find it most entertaining. I really should get out more.

Not that reverse entropy doesn't exist mind you, that's what life does and it does so by increasing entropy locally. I foolishly thought I had an original thought "anti-entropic" I called it. But a quick search of Wikipedia revealed that in 1943 Erwin Schrödinger coined the term negentropy from "negative entropy" to describe processes of life.

Oh well, I'll keep trying.

If you enjoy reading about "free energy", then check out the link in my first post. It actually allows you to download the blueprints for the vehicular onboard hydrogen generator and engine. What say everybody here each builds his own, then altogether say "UP YOURS" to the big oil companies who are killing anyone who discovers "free energy".

Can Entropy Be Reversed? Maybe or maybe I should say yes and no. By strict definition no.There is no perpetual motion (and probably no tooth fairy),but perpetual motion is not what we're talking about . One ton of A/C=12000 Btu I don't have the numbers in front of me so forgive me if I make a mistake,the math works out in a A/C unit to getting 4.73 Hp heat exchanged for about 1 1/8 hp input to the system. Its not something from nothing,in this case taking energy from the sun and coverting it to a more useful form for our needs, is no different than wind turbines or mirrors.

but perpetual motion is not what we're talking about

Actually, perpetual motion is what Kasmer is talking about. On his Peswiki page, he describes a perpetual motion machine, in which the output is plugged back into the input for self-sustaining operation:

Another capability is the Hydristor heat pump/generator. This Hydristor package will use Freon type technology which currently returns 300% of the input electrical power in the form of low grade environmental solar and geothermal heat. The Hydristor will raise the return from 3 times to fully ten times. The energy harvested from the air, water or ground will be sent to an available Stirling engine which converts 40% of the applied heat energy at 300 degrees F into direct shaft horsepower. The Stirling shaft now drives an electrical generator to create 3.5 Kw output per 1 Kw input. The last step is to 'pull the wall plug' and quickly plug the output into the input and the system is self sustaining with useable energy left over. You now have 'free energy' with true Zero emissions.

Hello KEN

I could be wrong but I would define perpetual motion as you did self-sustaining operation,there can be no outside energy input. Remove the external heat source it will stop, I think. IF placed in a totally isolated environment in theory the device could scavenge it's own waste heat( Maxwell's demon maybe damned),in reality I don't think so. Heat pumps have about a 4 to 1 return energy return in ideal conditions and drop toward unity at freezing temperatures. Also the greater the delta t is between internal and external temperature the more energy required per BTU transfered,about 1HP per ton for A/C to as much as 3HP per ton for a low temp box. I did the math a couple of years back, I think you could use a heat pump to extract energy from a relatively low temperature and convert it into a usable form, however the way my math worked out it's power input to output ratio would barely exceed unity under ideal conditions. I told it to Wilbur and I told it to Orville, and I'm telling it to you it will never fly. However I've been wrong before. If you hear a noise in the background it's me beating my head against a wall because this thing works and somebody else is getting rich instead of me!

Re: Can Entropy Be Reversed?

12/31/2007 2:35 PM

YW, I commend your open mind. You can see the lines around the box.

The Hydristor heat pump/Stirling/generator only will run self sustaining when there is

an 'outside the box' input of solar derived heat energy called temperature. As you

correctly calculated, existing Freon heat pump technology (4:1) will 'barely' be over

unity. BUT your number was slightly over unity. Not worth building a useable self

sustaining machine!. The existing heat pump technology has 2 major flaws. First, the

'expansion valve' is a small orifice (hole) which drops the cooled but still pressurized

Freon to a -40 temperature due to phase change physics. There is also a molecular

friction called 'molecular shear heating' caused by the Freon molecules rushing out

the orifice hole at supersonic speeds. This friction introduces a loss in the Freon cycle

in addition to the throw-away of mechanical compression energy in the expansion

process. In spite of these losses, the existing Freon heat cycle will return 3-4 times

the input energy. With the patented Hydristor system (US6,612,117, EU filings and

additional new patent pending to further improve the C.O.P.) , all I did was to

eliminate the compression loss by returning the cooled but compressed Freon to the

second Hydristor stage (first stage being the Freon compressor) and expanding

Hydristor stages 2,3, and 4 resulting in the conversion of the historically discarded

mechanical energy directly into motor torque on the common compression rotor. This

also eliminates the molecular shear heating. I believe this will raise the C.O.P. to 10.

The 'box' diagram would show a third energy input of low grade environmental solar or

geothermal heat AND a fourth output of useable electrical power. The harvesting of

10 kw of heat per 1 kw of input power, then sent to a 40% efficient Stirling to run a

90% generator will self sustain with useable output and I believe violate the wording

but not the intent of the hallowed second law that was concocted in the 1800s.

This is in no way perpetual motion and removing the solar heat input will stop the

self sustaining operation. The new provisional on file with the US Patent office is

about scavenging cycle heat losses for a further gain in C.O.P. and operation as a

pure hydraulic system or as a pneumatic system being the input power sources

and the self sustaining heat recovered useable output being hydraulic or

pneumatic accumulator tank pressure scavenging engine combined heat loss. Watch

for the discussion about the Carnot cycle when I introduce the Hydristor exhaust

system retrofit to harvest that huge heat loss of combustion coupled with an

additional Hydristor heat scavenge system recovering coolant heat, underhood air

heat loss and even some heat scavenge from the high rate of atmospheric heat

encountered as you drive down the road at 75 Mph. Actually, I hope to eventually

develop a heat scavenge system whereby the car just runs on Sun energy; no burn

of fuel. I believe this combination of thermal recovery systems can do it. I also am

convinced that the Hydristor hybrid storage system can make such a car beat any

alternate hybrid at a stoplight because of the massive power transfer of hydraulics

as compared to electrics. The friction brakes on your SUV develop a half megawatt

of 'power' at 75 Mph for the first instant of deceleration, declining to zero with the

speed. What electric motor and/or battery will ever be able to do that?

If we the engineers and scientists don't find ways to fix the mess caused by Man's

disregard of the environment and do it soon and fast, the future for our kids and

especially our grandkids is lost. I am trying to do this. Instead of finding fault as Ken

wants to do, look at the technology and propose improvements and ways to get it

into the mainstream. There will be a movie about the technology being ignored by

'naysayers', and in the public theatres in 2008. Not just my technology but a lot of

good ideas. I have been contacted by some of the magnetic motor and air vortex

guys and I'm not convinced but I try to have an open mind. I remain open to being

convinced. I know that is the position taken by most about my technology and I'm

going as fast as I can; with no money! That will soon change! Finally! All I ask is that

engineers take a comprehensive look at what I have done. The car stuff referred to

by Ken is provable on a sheet of paper in engineering terms. I have done some of

that but few listen. If anybody wants to call me, my number is 607-2068960 Tom

Hello Tkasmer

Sorry this reply is so long in coming, somehow I missed your post. You provided a lot of information in your reply and will take some time for me to digest this, I think you've taken a big step by explaining that this is not a perpetual motion machine. While I can certainly understand the skepticism expressed by some, I believe the technology of low-grade heat recovery is worth investigating.

As I'm sure you know the HVAC industry is phasing out many of the current refrigerants not only for environmental reasons but also for efficiency,the new 410A machines are outperforming comparable R22 machines partially because of decreased frictional losses in using POE oils instead of mineral oils, at least thats how I understand it. I've heard claims of equipment that provides 1 ton of cooling for every 1/2 horsepower input into the compressor although as yet I've been unable to locate anything approaching that efficiency.

Obviously even at that efficiency the machine I envisioned becomes much closer to being viable . One of the problems that I came up with in my thought experiment on the machine I envisioned would be optimizing the pressure temperature curve of the refrigerant (or perhaps I should say working fluid) to maintain peak efficiency at varying outside air temperatures, I would be interested in knowing how you are approaching this problem.

It would be a shame if a viable technology got thrown out with the 100 miles to the gallon carburetors,the fuel line magnets, and more free energy scams that I can remember. The November 2007 scientific American contains a article on newly viable copper rotor electric motors that are 93% efficient, I assume generators would also benefit from this technology, I mention that because every little bit of efficiency gained any place in the type of system you're talking about helps. The only thing I know for certain is we're running out of time in developing alternate energy sources. If nothing else you have shown me that I've got a lot of reading to catch up, while I'm not running out to buy padding for the walls (that I may end up beating my head on) the technology is well worth watching.

Instead of finding fault as Ken wants to do, look at the technology and propose improvements and ways to get it into the mainstream.

You must misunderstand my motives Tom. I have no interest at all in "finding fault" with scientists, many of whom have been unselfishly helpful in my endeavours. Try as I may, I cannot find fault with either the first law or second law of thermodynamics, with Newtons notion that F=MA, with Einstein's notion that E=MC2, and so forth.

I can find no fault with this from Wikipedia:

  • When used for heating a building on a mild day, a typical heat pump has a COP of three to four, whereas a typical electric resistance heater has a COP of 1.0. That is, one joule of electrical energy will cause a resistance heater to produce one joule of useful heat, while under ideal conditions, one joule of electrical energy can cause a heat pump to move much more than one joule of heat from a cooler place to a warmer place. Sometimes this is inappropriately expressed as an efficiency value greater than 100%, as in the statement, "XYZ brand heat pumps operate at up to 400% efficiency!" This is inaccurate, since the work does not make heat, but instead moves existing heat "upstream"; otherwise, this would be a perpetual-motion machine.

If there is someone "finding fault," you would seem to be that person. Your assertion that your machine delivers 3.5 kW output from 1kW input is entirely at odds with the wisdom of hundreds of brilliant scientists, thousands of ordinary scientists and engineers, and millions of ordinary educated people. You seem to be finding fault with their understanding that perpetual motion machines cannot work, and instead siding with the naysayers who say scientists are a bunch of nut cases.

If you want to find fault with the Wikipedia paragraph above, then you will need to provide a rational, clear, concise, and straightforward explanation of why it is incorrect. As I said, I am not here to find fault -- their explanation looks correct to me and to numerous scientists. If I were here to find fault, then i would say that their word "inaccurate" (in their last sentence) should be replaced with "utterly and totally wrong, and fundamentally misleading." What do you find wrong with their paragraph? In other words, what makes you think you have finally created the perpetual motion machine you describe (in Peswiki) as delivering 3.5 kW output from 1 kW input, and in which you simply have to plug the output into the input to get it to run forever?

There is great power in positive thought. Sadly the anti-science naysayers and purveyors of over-unity negativism seem to have won you over. You'd certainly be welcome back to the positive side where sound science is rewarded, should you decide to make that change.

Ken, I was referring to your comments about the vehicle retrofit and not about the entropy discussion. I would like to separately discuss the vehicle issue either on the CR4 site or in private e-mails and/or phone calls. I would hope for the opportunity to answer your concerns there. I don't want to disrupt the forums with anything like this. I believe that truth will stand the test of inquiry and I offer to debate the truth with you.

Regarding the heat pump, entropy and the second law, here are a few links:

http://www.arizonaenergy.org/News_07/News_Nov07/Thermoenergetics--%20Can%20Hydraulics%20Reverse%20Entropy.htm

http://blog.hasslberger.com/2007/11/thermoenergetics_can_hydraulic.html

The response by YW #15 to your #13 entry was right on. I am not in any way proposing perpetual motion. If a high COP recovery Hydristor heat pump can harvest 'external' low grade heat from outside the box, 2 sources of initial energy are running the system. If the electrical power input from the power company converts enough energy from the environment (that second source of energy usually ignored in the perpetual motion discussions) to result in more electrical power output than is coming from the power company, switching the output to the input and shutting down the power company will help the energy crises and is not a conflict with the second law. The hallowed second law was written in the 1800s and what did they know then? This is simple logic. My phone number is on the Hydristor website as 607-2068960 and my e-mail is tkasmer(at)yahoo(.)com. I welcome questions and will try to answer. Tom

If it were possible to make a heat engine that could operate on ambient heat by concentrating it, then in would not violate any laws of thermodynamics. It would simply do so by increasing the entropy locally. As far as we know so far, life is the only naturally occurring entity that concentrates energy by increasing entropy locally. Anentropic is how it is referred to in thermodynamics. Plants are simply machines that operate on sunlight. Their trick is efficiency. It, therefore, does not seem totally implausible that another machine, were it adequately efficient, could mimic this trick using ambient heat. The trick is gathering a lot of it and doing so with exceptional efficiency. However, you might be better received if you deleted your ambiguous references to the laws of thermodynamics and instead couch your descriptions in acceptable scientific terms. Chances are virtually 100% that if you indeed can make your machine work that it will not be necessary to explain it in any other terms than those we have found to be true beyond the shadow of a doubt.

Why swim upstream and garner opposition by using circumspect language? You don't need any violation of any known laws, just exceptional efficiency. Whether that is attainable is the only argument and you may find it helpful to make that your approach.

Re: Can Entropy Be Reversed?

Well I don't mean to endorse any obvious violations of known laws at all. Really I'm just thinking out loud. Now just ask yourself, how does a plant (tree, vegetable etc.) perform useful work? Well, it does so by absorbing energy from the environment and then emitting slightly less than it absorbed netting a slight retention of energy in the process. Now what do we do? We cut the tree down and burn it to heat our cabin. Tell me now, did we not just extract useful work from an environmental energy source? In this case it was sunlight but what about solar collectors that boil water and make electricity? No one argues that doesn't work. What are we doing? Collect heat from the environment, exhaust some of it and net some as a negentropic gain that can be used in a more highly ordered fashion. Now, if it were feasible to collect over a broad area, ambient heat and then to exhaust a portion of it, and this is key, at a different location, then what makes this implausible? It is no different from the machinery of a plant or a solar collector. Now granted, ~1000 watts per square meter may be more to work with but the idea is still the elemental heat engine. Take energy at a higher temperature, exhaust it to a low temperature reservoir and net a little utility. How about the little light powered spinner things in the evacuated glass bulb? Same principle, take ambient energy, exhaust it to a lower energy reservoir and net motion. Obviously not too useful but entertaining and so that is some utility.

Now clearly the thing that makes any of the things that we know as useful work is that they perform at an adequate level of efficiency. Is this guys machine efficient enough? Even if it worked would it be worthwhile as anything beyond a curiosity? I have no idea. I am only attempting to broaden my thinking about these sorts of things and see how what does work goes about doing so. This is how we have made many discoveries, observe and model nature.

Thank you for the insightful and intelligent comments. I am very accustomed to swimming upstream. I will take your points to heart and I especially appreciate the 'local entrophy' comment. I believe I am doing the right thing and I will continue. I believe the Hydristor will completely change the future for the better. Thanks Tom

Why swim upstream and garner opposition by using circumspect language?

Circumspect? His language is fairly straightforward. It is the claims that are outlandish. He says:

  • The Stirling shaft now drives an electrical generator to create 3.5 Kw output per 1 Kw input. The last step is to 'pull the wall plug' and quickly plug the output into the input and the system is self sustaining with usable energy left over. You now have 'free energy' with true Zero emissions.

That is a straightforward description of a perpetual motion machine.

  • I have a real solution and I must reach the people of the World. I plan to enter the Automotive X-Prize contest and I believe I can raise the economy of a Hummer or Expedition to over 100 Mpg with Hydristor retrofits.

That is a straightforward statement of a wildly implausible claim for what (in this application) is a continuously variable hydrostatic transmission, with nothing in its patent to suggest that it is substantially different than any other. (And even if one accepts the unlikely 97% efficiency claim, that efficiency is not fundamentally different than other CVT and manual transmissions.) Hydrostatic transmissions are some of the least efficient for the obvious reason that you are pumping a viscous fluid: there is tremendous fluid friction. They routinely require cooling fans, because they are so lossy. The UPS hydraulic hybrid trucks do not get anything remotely close to the 10-fold efficiency increase required to take a 10 mpg Hummer to 100 mpg. They are happy with a 2 mpg improvement. Part of that small increase is the CVT effect, part is the hybrid effect (of more optimally loading the engine).

  • A ten gallon air tank compressed to 5,000 psi is enough energy to propel a vehicle 40-50 miles.

(10 gallons per minute x 5000 psi) /1714 = 29 hp. The average pressure in such a tank (as it's fluid is consumed) would be 2500 psi. So, such a tank would provide 14.5 hp-minutes of energy. The average car uses 14.5 hp to go 60 miles per hour. So, 14.5 hp-minutes would provide for a distance of 1 mile. His statement is clear... unfortunately it is a flat-out lie.

  • Kasmer expects that converting a vehicle in to a Hydristor hybrid will cost around $3,000 - $3,500 USD. With gas savings, the return on investment will be about one year.

Clearly worded. Flat lie. 15,000 miles at the fleet average 20 mpg = 750 gallons. At $3 per gallon that is $2250 total fuel cost. Suppose Tom's system improves my fuel mileage 1000 fold, so I only use $2.25 in gas (less than a gallon per year). OOPS, sorry, even that will not pay back my $3500 investment in a year.

These quotes from Tom are here:

http://peswiki.com/index.php/Directory:Hydristor_Corporation

The Hydristor (roughly the same technology as a 40-year-old Cub Cadet hydrostatic transmission) has over the years morphed into a hydraulic hybrid system and now into a heat pump, of all things. There is nothing in the Peswiki article that clearly states the basis of Tom's "gut feel" for a COP of 10 (whereas billion dollar firms have pushed up COP -- which is marketable -- to about 4. It's not like car fuel efficiency which is unprofitable for the manufacturer... Carrier spends a lot to improve COP because high COP gives them a completive advantage.) Is it possible that Matos in Angola has out maneuvered Carrier? Yes. Is it likely, given the bizarre presentation of his system, the fact that it show up on a free energy site, etc? No. Is it plausible that a heat pump can be an over-unity machine? No. Heat pumps do not create energy.

Tom has suggested that because the second law of thermodynamics was formulated in the 1800s, it is about time for it to be replaced. This shows a profound misunderstanding of the scientific process (or a propensity for fraud). Old laws do not wear out like a pair of shoes. They are tested daily. The law is more valid now than it was in the 1800s -- not the other way around. Ditto for F=MA, etc.

If what appear to be lies to me are simply symptoms of dementia, then Tom has my sympathy. Otherwise all this strikes me as just another free energy fraud.

  • I would welcome any help in this adventure from those who would join me in my 'save the humans' quest.

Count me out Tom. If you want help, then publish in a peer-reviewed scientific journal, explaining how your system defies the second law. Simple, straightforward, and far more effective than posting here where no one is prepared to read hundreds of pages overturning conventional science.

Thanks Ken for taking the time to post your very thorough rebuttal to Tom's wild claims. I agree with every word you wrote. On the Yahoo free_energy forum, we have seen many scams over the years. It is important to challenge such scam attempts openly, hopefully helping some decent but less scientifically literate folks avoid losing their money.

After giving it more thought, I realize that I over-reacted to Tom's over-unity claims. I should not have publicly implied that Tom was attempting a scam.

I retract my offensive comment, and sincerely apologize to Tom for posting it.

I still remain skeptical of his over-unity/2nd law violation claims, but since I do not know his thoughts, I have no definite way of knowing whether he made honest mistakes or intentional misrepresentations. Until I have clear reason to think otherwise, I should assume he has sincere intentions (since I do adhere to the principle of "innocent until proven guilty"). I will try to retain a more open-minded attitude in the future.

Tom:

Please don't take my criticism of your approach as a personal attack: I am uncomfortable only with your ideas as presented, not you. Perhaps, after all, I am reading something into what you have said or written that is not your intended meaning.

Also, when I said that "no one here is prepared to read hundreds of pages overturning conventional science" I didn't mean that the several hundred page book required to present enough evidence to over turn the first and second laws of thermodynamics would be uninteresting. Rather, this online forum does not lend itself to posts that long. Certainly, if you are willing to post evidence or thoughts here of any type whatsoever, those posts might be welcomed by many here, if they conform to CR4 guidelines. Although I've posted a lot on CR4, I don't in any way represent the membership as a whole, and as I hope you know, the term Guru means only that I post a lot -- it could all be nonsense.

So don't feel I am trying to discourage any legitimate effort you may be making to advance science. And don't be afraid to run your ideas past others here. I can certainly refrain from commenting on your posts, to give you a break from comments you no doubt see as negative.

If you succeed in creating a machine which outputs 3.5 kW from a 1kW input, I will be among your loudest cheerers.

Good Luck,

Ken

Re: Can Entropy Be Reversed?

This is NOT perpetual motion guys! A commercial heat pump will reach a gain of 3 (called coefficient of performance or COP). Electrical power is supplied to run the compressor and the cold Freon gas is sent to the outdoor heat source which is air or water (coming fron the Sun!) or ground water under the soil which is a mix of solar input and geothermal. These systems have been commercially available since 1950 and they work. Again, for every kilowatt of input, a harvest of 3 kilowatts in BTUs is sent indoors to heat your house and your electric bill is cut in half or by 2/3. I don't know of anybody who calls this perpetual motion because there is a third element (Sun) feeding energy into 'the box' in addition to the electrical input and the electrical input enables the capture or harvest of up to 3 times the electrical power level.

If the 350 F heat output of the 'hot' exchanger were applied to a 40% efficient Stirling engine (40% at 300F), there would result 1.2 horsepower of Stirling shaft rotating power output per 1 Kw fed into the Freon compressor. If you now connect an electrical generator to the rotating Stirling shaft, 'maybe' you would get 1 horsepower (746 watts) of output and this would not run and be self sustaining.

Using the Hydristor to replace the inefficient 'expansion valve' where compression mechanical energy is thrown away, not to mention the molecular friction loss of Freon molecules screaming through the tiny hole called the expansion valve, and at very high speeds, the overall system performance is substantially raised. I am estimating a COP of 10. I have filed a new provisional patent which describes improvements which will raise the COP to 20. If 1 Kw is supplied to the Hydristor Heat Pump, 10Kw BTU equivelent solar air or water borne heat is harvested and sent to the Stirling where 40 % is converted into shaft horsepower (about 3 Kw) and an electrical generator at 90% will create abaout 2.7 Kw of electrical power. This power can be switched to the input and the system will run as long as the Sun burns, providing 2.7 Kw per 1 Kw recirculated to the input. Obviously there are controls which I'm not going to discussas they are intellectual property.

The wording of the Second Law says I can't do this but they didn't know about high tech issues like this in the 1800s. This is not perpetual motion in the strictest sense of the word. An example in nature is Niagara Falls. The Sun heats the water and the vapour 'rises' against gravity (effectively water is running uphill) and rains on the hills and fills the Great Lakes. The gravitational drop runs electrical turbine generators and 'Voila', free electricity! This too will stop when the Sun stops burning.

NOT PERPETUAL MOTION!!!!!

The Hydristor Freon system mimics Niagara Falls and Iam calling the technology

"Niagara Falls in a box'

Systems like this will oneday power cars FOR FREE and will not make EMISSIONS.

If it were possible to make a heat engine that could operate on ambient heat by concentrating it, then in would not violate any laws of thermodynamics.

This sounds incorrect. I would say that extracting energy from ambient heat *would* violate the second law of thermodynamics if the method involved no temperature differential (a hot source and a cold sink). And what does it mean to "concentrate" ambient heat? I could compress ambient air and thereby increase its temperature, and use this higher temperature to run a heat engine. But the energy required to compress the gas would exceed any energy produced. Many scientists and amateurs have already considered using heat pumps (because of their COP > 1) to violate the second law. If it was so easy as Tom claims, surely we would have seen replicated proof by now.

Re: Can Entropy Be Reversed?

I understand. However the essential requirement for netting useful energy is to have a high temperature reservoir that you can flow to a lower temperature reservoir. In a very large scale where the sun is part of our local environment we use that high temperature reservoir and exhaust it to the low temperature reservoir of our more local environment. Thermal energy stored in our local environment must go somewhere, ultimately it is radiated into space. This may not be a heat flow of adequate magnitude to develop a useful means of extraction, I don't know. Perhaps we just don't know how to be that clever yet or maybe it would never be practical but we seem to do ok with wind power which in a way is a means of extracting some of the less direct effects of the ingress of solar power. So there you go, you have the wind. Could there be a form of wind power that used, instead of a large rotating blade, a very large gaseous heat exchanger? Look ma, no moving parts! I'm just trying to think a bit outside the box here, not jump in the same box with the perpetual motion crowd. Maybe there is a way to use wind power, just in a different way, for example? I am just asking, is there not some possibility to obey the laws we all know and love, and simply find a method that may open some new opportunity to harvest low grade energy such as wind in a way yet unthought of.

however impractical (now, eh?)

attempts are to synergistically find other balance within something of a mirror image of the "law"

but I do not see in as law-opposition: as for while "concentrating" "gathering" "moving" media to some differencial-(temp or pressure, etc) requiring less energy than what can move in to a moved media of a difference

HI Rcapper; you wrote (If it were possible to make a heat engine that could operate on ambient heat by concentrating it, then it would not violate any laws of thermodynamics). I could be wrong it looks like you're seeing what I'm seeing. I don't see a violation of thermodynamics. Ken backs up his position with numbers and I think that his own numbers of 4 to 1 energy returned would at least indicate that a self-sustaining machine would be possible.

I hope you'll forgive me for making what possibly should have been a general post in my reply. I'm sure Ken will be reading this and I'll ask his forgiveness as well as everyone else's for posting an abbreviated bolognium guesstimate. 1HP= 2544 btu. Assuming a 1 hp compressor equals 1 ton of air conditioning, and also assuming that the four to one return includes a parasitic loss of the fan on the outdoor heat exchanger (about 1/16 hp power per ton) leaves me with about 10,000 BTU surplus.
10,000 BTU input into a 30% efficient engine leaves me about 3000 BTU, 3000 BTU input into a 93% efficient generator leaves me about 2790 BTU, of which I will need to put 2500 BTU back into my system to regenerate. Leaving me with a net surplus of 290 BTU. My Rube Goldberg machine should supply enough surplus energy to heat up about a half a gallon of coffee. Could be wrong not a physicist just a mechanic and I'm not saying that it could be built just that it's possible. Of course there a lot of unknown variables, the first of which would be represented by efficiency divided by Murphy. I wouldn't consider my machine to be perpetual motion, just the world's most expensive coffee pot. Ken or anybody else feel free to disagree with me or show me my errors, I've certainly been wrong before.

Hi YWroadruner:

Here's a link to look at. Hyperphysics is put up and maintained by Georgia State Univ, and it is extremely well done. You can follow the links as far as you want into this.

Heat pumps of COP 4, 5, 6, or even their theoretical maximum do not operate at over unity -- they are not a key to a perpetual motion machine. Dreaming and wishing will not make perpetual motion happen, as far as I can tell. Saying that you can plug the input into the output and have the system continue to run is precisely equivalent to saying that you've created a perpetual motion machine -- in fact it is the classic test. A heat pump with no pumping losses at all cannot operate at over unity.

Anyone who has created such a thing need only submit it for the million dollar prize for a working perpetual motion machine. Spending time here promoting such a thing would put the prize at risk -- now would not be the time to delay. I'd love to see Tom claim that prize.

Hi Ken....... I'm back! Just kidding, I ran into some interesting information while I was on the for RayPac website getting some boiler control diagrams.
http://http://www.raypak.com/jumpPool.cfm?target=heatpumpchoice.htm

RayPac features a heat pump pool heater with a COP of 5.5. This is the highest efficiency rating I have seen to date in terms of an operating machine. Just thought I would add to the conversation and stir things up a bit. I know we must agree to disagree on at least a theoretical possibility of what we are discussing which I would not refer to as perpetual motion merely a heat recovery or if you will a heat concentration device. And to clarify I'm not saying such a machine could be built I'm just not sure it couldn't. Thought you and some of the others might be interested in the current state of the technology.

Sustainables CR4 , no over-unity or "free" energy device was described at all:

Pre Cooliing , Process Cooling was more so later understood by only a few significantly a result of , and however poor the English:

Pre Cooling - heat-sinking is within an electrical energy savings compared to refrigeration chiller inputs @ total utility $ of 84%-90%. Those would be in to ratio's of over 9 to 1 of the relative horsepower of refrigeration to the resulting refrigeration/cooling used by industry since the 70's or earlier... + ; and in 50f to 60f conductive soil conditions and/or ponds, lakes, streams - just not about "anchored barges on flowing rivers":) -eh?

Observed electrical Industrial and Process Cooling COP's of are around 10; ~

and in other words 27 to 31 "Tons/hour" ( 360,000 btuh ) of process cooling with a 1500w to 900 watt ( 3600 btuh ) recirculation system of in to a common 12 circuit x 1" PE 3408 11ft deep pond -ground-coil summer-to-winter, respectively, as found in 10 to 20 "ton" geothermal systems for attaching to water source heat-pumps...[ BUT NOT WITH ANY HEAT PUMPS GTHP's/GHP's OR CHILLERS for as connected to the gle- pond cooling system ].

NOT "FREE" ENERGY AT ALL

but I say used-energy just within a media that is MOVED. (we never created nor ever 'moved' heat or any energy, nor 'made'/'produced' energy, as it is going to do that by harmonious complexities beyond the limited human "intelligence we search for" in just putting a media in a differential-place.) :) >

Re: Can Entropy Be Reversed?

12/05/2008 5:25 PM

Tom Kasmer here, I've been busy. Is Niagara Falls electrical generation 'perpetual', (free and lasting until the Sun burns out!)? The system I have proposed and patented simply is a higher C.O.P gain Freon heat pump which eliminates the decompresion loss and molecular 'shear friction' loss and attains a much higher gain.

I can buy a Freon heat pump with a gain of 3X. If I use 1.0 kw from the power company, I can harvest 3 kw from the solar heat in the air or water PUT THERE BY THE SUN during daylight hours in the form of air or water temperature. I can also buy a Stirling heat engine from MTI in Albany, New York. Their Stirling converts 40 % of the applied heat energy at 350 F into shaft horsepower, or 1.2 kw output. The addition of an electrical generator (90%) to the Stirling output shaft results in 1.08 kw of output. Theoretically, one could quickly disconnect the power company and substitute the generator output and the rig might run self sustaining. There would be no extra output left over to power anything. This is with existing hardware. The Hydristor gain will certainly be greater than 3X and I am estimating 10X. This is not and never has been advertised as 'perpetual motion' just as Niagara Falls is not perpetual motion. The Solar energy is the third element fed into the box. If the Hydristor system were put into a box in the cold of outer space, it would not run. The Hydristor heat pump is not and I have never claimed it to be 'perpetual motion'. It is simply mimmicking Niagara Falls solar energy recovery.

The Second law was drafted by Carnot in 1824 and the Freon heat pump was unknown at that time. The language of some versions of the Second Law is in conflict with modern Freon heat pumps and they work. All I am doing is increasing the heat recovery efficiency.

Hello Tom, I admire your perseverance in trying to explain why the device you discuss is not a perpetual motion machine. But I think that this discussion needs clarification of a very specific point. Most people (even scientists and engineers) do not realize that their are two types of perpetual motion machines, each type corresponding to which one of two thermodynamic laws would be violated. The vast majority of proposed devices are those that would, if they functioned as claimed, violate the 1st Law of Thermodynamics (conservation of total energy in a closed system). Bessler's perpetually unbalanced gravity wheel is a one of the more famous examples. The less common type of perpetual motion machine instead allegedly violates the 2nd Law of Thermodynamics (non-decrease of entropy in a closed system). Let's call these perpetuum mobile of the 1st and 2nd kinds, respectively.

I agree with the vast majority of scientists and engineers that a perpetuum mobile of the 1st kind is so unlikely as to be essentially "impossible" (i.e., if such a device seems to function, then it must draw its energy from some hidden here-to-fore unknown phenomena like cold fusion/zero-point energy/parallel universe etc, but not simply ex nihilo from "nowhere").

But proposals for perpetuum mobile of the 2nd kind should be examined more carefully, since these have a seemingly less-infinitesimal probability of success in that they don't violate the 1st law. Violation of the 2nd law seems somewhat less outrageous than a violation of the 1st law (at least to a small subset of academics) because 2nd law violators "simply" concentrate existing thermal energy rather than creating energy from nothing. When skeptics respond to 2nd law violation claims, I ask that they point out a specific technical issue where the device should fail, instead of the vague blanket rejection routinely applied to 1st law violation claims.

Now on to the specific question I alluded to: does the device in question operate off of an temperature differential? If so, it is simply a heat engine. If not, it would need to violate the 2nd Law of Thermodynamics.

Re: Can Entropy Be Reversed?

12/06/2008 7:52 PM

The point is that the Hydristor heat pump generator is not a perpetual motion machine because the energy comes from outside the box. I guess I have been sensitive to charges of 'perpetual motion' and have tried to argue from that position. The energy clearly comes from outside the box and is supplied by the Sun. Photovoltaics are a clear example of essentially the same thing. If you cast sunlight on a photovoltaic array, free energy flows out electrically. Another form of solar energy is infarad heat energy which is stored in the air and water temperature. The Hydristor super Freon heat pump simply creates a heat flow mechanism based on Freon phase change whereby the natural entropy is 'fooled' to flow toward an artifically colder sink and is trapped there for subsequent conversion to very elevated temperature in the hot exchanger and the result is that heat flows in apparent opposition to entropy; ie: if you will, water flows uphill. This is an engineering trick based on phase change. Carnot did not know of Freon in 1824 but this kind of system has been possible for a long time. If I can harvest 10kw of heat per 1 kw of power and get it to be self sustaining with useable output energy, it will change the future for our kids. If my ideas sound nuts, consider 'clean coal' and carbon sequestration in the earth or in deep sea pools. That is nuts! If we could actually and safely store the CO2, we would still be gradually burning atmospheric oxygen and taking it out of circulation with the result of gradually dropping percentage of oxygen for mammels (like us) to breathe. Combine that with the worldwide reduction in plantlife, Nature's CO2 to O2 converters and the problem gets worse. That may take a hundred years to get serious but it is another example of Man's ignorance. Nuclear power is touted to create electricity in a way so as not to feed global warming. The proponents fail to mention that the huge quantities of heat created by the reaction is dumped into rivers, ponds, lakes and the oceans. That is a direct addition to global warming and they want to build dozens more? If I could get the financing to make some working models, I could create a gridless energy system which would be a lot more secure from attacks by bad people. That is generation at the point of use.

I have dedicated 18 years of my life to the Hydristor vision without a formal income. It has been a monumental sacrafice for me and my family. On February 14 of 2008, I was operated on for a heart attack and received quad bypass surgery. On February 21, I left the hospital and went to a hotel room near the hospital and began work on a Hydristor conversion to an English electric car. This car has a high tech on board generator to charge a modest battery array and the Hydristor will triple the range to in excess of 200 Mpg. On board creation of Brown's gas is also involved. I have worked hundred hour weeks on this design and it is finished. I can't say more as I am bound by non-disclosure agreements. I also have an opportunity to develop the powertrain for the new Army truck and I am principal to a new company whose sole purpose is to retrofit every vehicle on the planet to the Hydristor hydraulic hybrid conversion system which triples highway mileage and raises city mileage to near the greater highway mileage while quartering CO2 emissions of existing vehicles. This technology has the promise of fixing a hell of a lot of problems; rolling back global warming, cutting the USA use of oil in half and extending the oil supply in the Earth to 75 years, giving us time to rationally rework the overall system. I eventually want to power cars with the Hydristor heat pump system and eliminate fuel of any kind. That is what we must do if life is to survive. I'm doing this for my kids and grandkids and for your descendants as well. I am in this forum because I believe that engineers can save the future. I try my best to be accurate and I always leave my name and contact information unlike critical entires in Wikipedia. I have no problem with constructive criticism and I welcome a debate at an engineering and professional level. The times are very critical economically and the adoption of the Hydristor by the domestic big three could save them and return them and us all to prosperity. The beauty of the Hydristor hydristor conversion is that it fits the existing transmission outline and raises the average fuel economy to 40-45 Mpg overall for Hummers, Escalades and Expeditions, and it fits all the existing vehicles on the road and all the new vehicles in the production pipeline. Expeditions would disappear from the mile by mile Ford parking lot on I-75 south of Detroit; they would be sold to buyers who want them without wrecking the existing manufacturing system plants would re-open and workers would be rehired. Our economy would become vibrant again. I have 35 years of experience as an engineering consultant in many fields and the last 18 years dedicated to my vision. I am 69 years old and going like hell to finish this after my wakeup heart attack. I hope I am granted the time to do this and I must not fail.

Does the Hydristor rely on a temperature differential? (i.e., a hot sink and a cold sink) If so, then does its energy efficiency exceeds the theoretical Carnot efficiency? That would definitely make it very interesting.

If it does not need a temperature difference, but instead converts ambient heat (at uniform temperature) into work, then it violates the 2nd Law of Thermodynamics -- making it a perpetuum mobile of the 2nd kind.

I don't mean to be argumentative. I ask a simple yes/no question becuase I sincerely want to know.

Dr John Jones and Michael Rice PE ME achieved a couple percent and gave up on low pressure steam turbines in refrigerant in differentials of 0f days in Dayton to there 54f soil "conductions"

in 1979, interestingly

today process or pre- cooling and pre- heating with just a fluid circulator hit 10+ COP's and $ 100,000 delivers over half a million btuh near 20f days , from 52f ditches.

Pre coolers of $ 100,000 are delivering 100 to 150 tons of net usable chill.

http://blog.hasslberger.com/2007/11/thermoenergetics_can_hydraulic.htm

However argued: About the 330% to 600% +, more heat energy than 100% electrical COP of 1:1 to COP's of 3.3 to 6+ to one,

where is there any "free" energy or perpetual motion thereof?

Appears as only an incomplete movement of some media (gas, vapor, liquid) withing temperature and/or pressure differentials to complete some usable representation of moving a/another media for useful work. -Practicality aside or not, what is the outcome this year?

It's a Christmas miracle. At least the Kasmer guy is designing it for the right car:

"Having done the design, I am now working on the financing of several prototypes for a Ford Expedition and a DeLorean DMC-12."

Make sure you put Einstein in the passenger seat for the test drive.

Sorry to be sarcastic, but I'd have to see it to believe it.

Even seeing it might not be sufficient for me to believe it...

Actually I saw a demo' that purported to reverse entropy years ago.

A fixed transparent cyinder, had a similar cylinder mounted within it, this cylinder could be rotated by a handle...the small gap between the two was filled with clear gel...A spot of coloured gel ( abot 20mm across) was injected into the middle, As the handle was turned the spot became a smear and dissapeared.

On reversing the rotation the smear was reassembled into to spot ! It was quite a fun demo......
