Self-Running Ambient Heat Engine

[boguslaw]

Only electrons can do that...In my opinion Tesla used electrons to tap ambient field, in fact it was not his idea originally

[Tom Booth]

Puzzled?
How?

Well, the image is from a site about Lind's process for liquefying air by a thermodynamic process of compression cooling and expansion.

Are you suggesting this somehow had something to do with electron gas or electrical something?

[Ernst]

Exactly.
If you've read my thread and linked documents, then you somehow missed the point.
Tesla found that whatever causes electricity behaves like a gas. Modern science has come to the same conclusion for free electrons in a conductor, but they do not take the next logical step. Tesla does.
If that which causes electricity is like a gas then gas laws should apply and so, Linde's system has an equivalent in electrical engineering using electron gas as a working medium.
You can compress it in a Tesla coil and a discharge would be a sudden expansion resulting in a cooling effect.

I thought my video would make that clear, but apparently not as clear as I thought?

[Tom Booth]

Thank you. That clears things up quite a bit As well as making your entire presentation a lot more interesting.

I must confess I began to tune out quite a bit at points as it seemed to me you were somehow confusing issues.

I certainly can't deny that Tesla was involved in electrical phenomenon I personally have no idea about, and it only seems logical that free electrons should behave just like any other free particles.

Still I don't think Tesla was talking in code or symbolicly in his article about the "Self Acting Engine" in Century magazine in 1900, though I certainly can't deny he might very well have spoken about the phenomenon of which you speak elsewhere.

It seems to me that at that time in the Century magazine article Tesla was talking strictly in terms of thermodynamics from start to finish as far as references to his self acting engine go anyway.

Would that be how those thermoelectric coolers work, by compressing and expanding electrons using various conductors and resistors in a manner similar to the condenser and evaporator and throttling device and such in a refrigerator?

You would think anyone who has read Tesla would be familiar with him explaining electricity in fluid dynamics. If it works with a gas there is a direct analogy to electricity and vis versa. So even if Tesla's ambient heat engine is a purely mechanical device.....He is still making a direct analogy to how electricity behaves......I would not call it a code so much...I would say making analogies between how a gas behaves and how electricity behaves

My work was with Stirling Engines years ago. In attempting to design a more efficient Stirling Engine, at one point I was trying different cooling systems. More or less randomly I started toying with air cycle refrigeration in conjunction with the Stirling engine. I came up with what I thought was a good combined Stirling air cycle solar generator and had this machine running on a parobolic dish concentrator in my imagination.

As I ran this machine in my head... I suddenly realized the sun had set and yet the engine kept running, apparently able to effect its own cooling while continuing to run on ambient heat. Though this was only my own vivid imagination, I was shocked.

I kept the thing running for days without a dish, just pulling heat from the air.

When I called the contractor who had recruited me for the project, he consulted with some experts he knew from the DOE I believe. They told him it was impossible and he didn't want to hear any more about it. BUT I KNEW in my mind it would work. But there went my partner. There went funding. I became a bit obsessed with it. This engine I wanted to build and prove could work. Then one day I happened across Tesla's article regarding his self acting engine. He was describing the engine I had running in my imagination to a tee.

Prior to reading Tesla's article about this engine I knew virtually nothing about Tesla. Needless to say I was flabberghasted.

I'm relating all this as an explaination as well as an apology, I'm not any kind of expert on Tesla. I havent read much of anything he's written or anything written about him beyond whatever else I could find regarding his Self Acting Engine.

I agree. I just thought it was more fun to call it a code as we have a Da Vinci Code, now we have a Tesla Code.

Yet at some points in his works it is not an analogy he uses, it is more like he tries to hide his true message a bit. But it is 95% analogy....


Ernst.

[Tom Booth]

Personally I don't see anything in Tesla's article to suggest or indicate that he meant anything other than what he said.

I think that trying to read too much into it could just end up obscuring the plain and straightforward statements of fact and personal observations made by Tesla in the article regarding his Self Acting Engine.

If he was talking ordinary thermodynamics, heat engines, air compressors, refrigeration units, real nuts and bolts objects that anyone can see and understand and observe, then considering it to be analogy with some parralel deeper "TRUE" meaning may just lead us further away from rather than closer to the truth.

[Ernst]

That is your opninion.
We will see which opinion will lead to results.


Ernst.

[boguslaw]

The process is known and called Faraday Induction law

[Tom Booth]

That is your opninion.
We will see which opinion will lead to results.


Ernst.

I'm not saying your view is wrong. Tesla often spoke in broad generalities or universal principles.

If he says "much energy" and "little energy" I tend to read that as Heat and Cold , but obviously he could have said that. He may very well have worded it that way so as not to rule out, or to include other possibilities like higher and lower electrical potentials. I certainly don't discount that possibility and I don't necessarily think it has to be strictly one or the other.

It could be both or neither depending on, is the underlying principle sound?

[Tom Booth]

...

All of the principles to build an engine like this have been discussed earlier in this thread. The only thing missing is the specific design, which of course is a critical omission.

Tom, I am interested to see what you can do with your ideas. If you ever want a little help, just PM me. Thank you for keeping this thread alive!!

One thing that keeps me interested in this is the information collected on this site regarding the energy in compressed air:

COMPRESSED AIR IS SOLAR ENERGY

I have also come across additional references to the effect that ALL the electrical energy used to compress air by means of an air compressor is converted into heat.

I see this as similar to compressing a spring. Air is elastic. when compressed, all the energy put into compressing the air is converted into heat, but there is still additional latent heat in the air that remains even after the air is compressed and all the heat/energy added to it is lost.

When the compressed air is used to operate an air tool it "springs back" and expands. In doing so it uses heat energy. If expanded against a turbine the expanding air can turn the turbine even though all the energy of compression has already been lost. In the process the air uses up some of it's own latent internal energy and this causes a sharp drop in temperature. If the turbine is very thoroughly insulated so it can not absorb heat from the surroundings as it expands, the air can even drop to cryogenic temperatures, far far below ambient.

Given all this, if we can reclaim 100% of the heat of compression, and still use the compressed air to do additional work drawing on the air's "internal energy" It seems to me we have already done more than break even.

Yet NOW, after all this, we are left with a potentially near cryogenic cold sink into which more ambient heat can flow into and use this to extract more energy... NO?

It is not true that we are missing a specific design. I have several designs for machines that could utilize these principles. I've already spent several thousand dollars on machining equipment to build them.

It shouldn't be long now before I'm able to get some of these machines built or put together, but I can say it IS challenging. Machining any kind of engine with precision parts such as piston and crankshaft is a major challenge.

I should say, I do not have a 100% exact design for a working machine. I have several rough designs that may or may not work. There are of course specific details to work out like the exact length of "condenser" tubing needed to achieve maximum performance, the exact bore of the cylinder, the length of the stroke of the piston etc. but such considerations don't change the basic design but will no doubt require some trial and error to get everything just right.

There are other things to work out like what to do about ice build up, but IMO if the thing runs and ice build up becomes a problem, that would constitute a working "proof of concept" engine. There wouldn't be any problem with ice formation if the thing wasn't running. These kind of problems are relatively minor and incidental. The main goal in my mind is to simply see if it works.

This claim about compressed air giving up 100% of the energy of compression as heat is not some outdated or obsolete information from old textbooks.

That you can compress air, reclaim ALL the heat and still use the compressed air, in effect utilizing your energy twice, is still a phenomenon that is recognized by companies that are in the business of heat energy reclamation:

Hallo,
i think, you must look for this: Organic Rankine Cycle
https://de.wikipedia.org/wiki/Organic_Rankine_Cycle
Heat energy recovery technology | Scoop.it
In Germany, has a man that combines with a car. The consumption went from 6l / 100km to 3 l/100. He has also a patent. I must look for it.

I've said this before on various forums, possibly earlier in this one, but I think maybe it could use re-emphasis at this point.

I think that we already have a working example or "proof of concept" model of Tesla's "Self Acting Engine" embodied in that toy "drinking bird".

Sometimes I think that maybe Tesla, or someone in a situation where they could not get the idea of a "free energy" self powered engine across to a scientific community blinded by the idea that "it's impossible" put that little harmless toy out there to be carried forward through history to some future more enlightened age.

This simple little toy meets all the requirements Tesla described for his ambient heat engine.

First, it IS a heat engine, Second it produces work as heat passes through it. It converts heat into other forms of energy in its passage. It maintains its own "cold hole" or "sink" and once started continues running, converting ambient heat into motive force "with no further effort" on our part, indefinitely. It is a refrigeration system as well as a kind of air compressor creating a temperature difference as well as an internal pressure difference.

If someone were to say that it only runs by evaporative cooling, I would argue that without the mechanical motion which certainly augments and accelerates the cooling as the wet bulb of a head swings back and forth it likely would not run, or at least not run so well of so fast or with as much force.

In other-words the birds cooling system is not JUST natural evaporative cooling. To some degree its simple refrigeration system depends upon and is driven by the mechanical aspect of the apparatus.

So what's my point exactly? My point is, demonstrating the truth of Tesla's idea is quite simple really. Just take a heat engine and give it some cold for a sink instead of heat so that it uses ambient heat as it"s actual hest source, then use the energy output to repeatedly and continuously replenish the "cold" as necessary.

There is not really any need to worry about where the energy is coming from. The real problem is WAY TOO MUCH ENERGY ALL AROUND ALREADY.

The real problem is how do you get rid of
all that excess energy that you don't need.

Luckily it is easier to get rid of excess energy than it is to make energy. The sun pumps PLENTY of energy into earth's atmosphere. Way way more than we could possibly ever utilize. In fact we can't utilize it at all until we start throwing a whole lot of it away.

Finding "free energy" isn't the problem. The problem is getting rid of the energy excess .

[Peter Lindemann]

Absolutely Correct!

Tom,

YES, I first suggested that the Drinking Bird was an embodiment of Tesla's "Self-acting Engine" in a lecture I gave in 2012. The Drinking Bird was invented in China sometime before 1922, when Albert Einstein reported being amused by one in a shop in Shanghai. Whether the inventor knew of Tesla's idea of an atmospheric heat engine is not known. What is known is that he solved Tesla's criteria for creating an artificial "cold spot" that could constantly replenish itself using a natural process, thereby allowing the device to draw in heat from the ambient air and channel it through the device and produce mechanical energy in the process. So, evaporation of water creates the cold spot, and the confined dichloromethane expanding and contracting changes the balance point of the Bird so that it alternately becomes either "top heavy" or "bottom heavy," creating its "drinking motions" on its stand.

The other important lesson of the Drinking Bird is that it shows that even small temperature differentials can be sufficient to demonstrate the complete cycle in a well engineered device. I own a couple of Drinking Birds and have played with them quite a bit. Interestingly, they work better with warm water than with cold water. They work best on a warm day with low relative humidity. On days of moderate humidity, once the Bird's head is wet, it will bob up and down for up to 30 minutes without needing anymore water. Under most other conditions, the Bird works better when drinking from a cup of isopropol alcohol, since it evaporates more easily and accentuates the cooling process. Continuous use of isopropol alcohol is not recommended however, because it is not good to breathe and may degrade the glue holding the red felt to the Bird's glass head.

The point is, Tesla was right and it IS possible to build an engine on these principles. The question is: when is humanity going to perfect this machine at an industrial scale and provide itself with unlimited energy from the Sun, 24/7?
