Ambient heat engine

Ambient heat engine
I don’t understand why there’s so much discussion about free energy. We’ve already got wind turbines PV panels etc. and why doesn’t someone build the Tesla self acting engine? I suspect it’s because it’s too expensive.
Anyway I intend to have a go myself. I couldn’t find a good description of this device so I thought “how hard can it be” and sat down with pen and paper. My first two attempts were obviously not viable but then after several months I tried again and in 20 minutes I came up with a rough version of my attached sketch. I’m going to start by building a simple heat pump using air con parts then do some experiments with that and then gradually build it up into something like what’s in my sketch. I don’t yet know what working fluids to use, I’ll start simple and experiment.
I can’t see any reason why my device won’t work, absorbing ambient heat isn’t difficult, see the green section in the sketch, then all you need is to boost the temperature high enough to power an engine driving an alternator. In my sketch this is achieved with a two stage heat pump. If this is inadequate or too much then any number of stages of heat pump can be used.
A high degree of efficiency is not required in any part of the device as the vast majority of the losses can be fed back in, if necessary using cold Rankin fluid to cool parts of the device then feed it back to the boiler.

I am very happy you raise this subject the most abundant energy on this planet is ambient heat.
And i have had this discussion before with several people that a normal air conditioner using R22 IS
ABOUT COP 3.. And it amaze me that here in OZ we do not heat up our household water with a small
mode using a small heat exchange within THE AIR CON..There is already such things but not marketed here..

@skaterboyles,


I do not normally enter into these sort of topics, but as you have stated you intend to spend a lot of time an money I felt I should tell you that it really is not going to work, and if you think about it there must have been 10 million competent engineers before you that did such a sketch, got excited, built it and then found out that it does not and cannot work.


It is not whether you believe me, but rather that you have a reality check and ask yourself if you have created something so different and novel from your predecessors that it has some merit in being pursued? If not then you are simply travelling down the same doomed pathway of millions of other well meaning but amateur engineers.


There are many here that can tell you why it will not work in detail, but let me simply say to you that a heat engine converting heat derived from compressing a working fluid will not deliver enough energy for you to compress (and so heat) the working fluid by which the heat engine works.


If you have time and money you wish to spend you should direct it towards new research and ideas.


Regards


Phil H

You will need a refrigerant with a very high temp at the end of the compression cycle as the gain is only that of latent heat , which Is a gain in heat capacity but at the same temp.The Carnot cycle at the end is the biggest problem, so inefficient at low temp differentials.

Seriously skater / john, you are wasting your skills time and money on an already flogged horse. IMHO you should use your energy on things that have a chance, and there are many good causes in energy. Regards Phil

John, looking at your site, I see some good ideas. The idea of using heat pumps to 'self-loop' is possible, but not yet practical. Imho, the obstacle is the refridgerant.
I'll be happy to comment further after spending more time reading your ideas.

John please ignore Bill's opinion about what is possible, he won't be there to compensate you for the time and money you will waste.

Philip, considering your track record of bringing products to market, your remarks don't carry much weight.
Although I was (and am) supporting you in the pursuit of a Quenco like device, you have never succeeding in a practical product.

Ooh, owch, but Bill if you think that is a fair comment then it would serve to warn our friend that it takes a small fortune, 6 PhD's and many years to then have idiots make snide remarks about things they know nothing about. I can with 100% confidence say that, no arrangement of compression and expansion, using any refrigerant known to man, will ever achieve closed loop operation with excess energy out when operating from a single (ambient) reservoir of heat with no lower temperature heat sink used.


If you want to talk BS you should use your own money and not give encouragement to a nice and skilled man, like our friend, to waste his own.

What are the hurdles that have been flogged to death?


The idea that heat pumps and heat engines can ever defeat the Carnot limit, and so as Pomodoro points out you will not scavenge free energy from ambient using such technology. Whilst home heat pumps can achieve exceptional heating efficiency yielding, say 4kW of heat output for 1kW of electrical input, the heat so scavenged from ambient is insufficient if used in a perfect heat engine (say a Stirling), to produce 1kW of electrical output so required to make a closed loop perpetual motion scheme.


This is a fact and despite 1,000s of amateurs hoping otherwise, it remains the issue that has been flogged to death for 150+ years.

Hello! The use of low-grade heat and transfer it into electricity is a reality today. I have developed a pattern, working on phase transition and generating 0.085 Watts of power. The device environmentally friendly and can be operated for a long time. This is only the beginning.

a more economical approach, if one has two reservoirs, a source of heat, and a source of cold.
would be to use the interface between the two, creating an impedance of some sort to negotiate the transfer of energy.
the heat will naturally migrate to the cold heating up the cold region in an attempt to balance out the difference.

for instance, the peltier/seedbeck effects could be used to draw usable electricity from an insulating wall.
this could provide more usable energy then the carnot cycle, but lets look at a sterling engine placed at the same interface.
approx. 50% of the potential difference in heat energy could be used as mechanical power.
by allowing the heat transfer to occur in a natural (but controlled) manner.

let's say it were hot outside, and cold at a level just under the ground.
a house in the middle could generate usable energy by maintaining a temperature somewhere in the middle.
when the inside gets too hot, generate energy by transferring the heat into the ground, when the house gets too cold
generate energy by transferring the outside heat to the inside.

a well designed heat pump will circulate fluids on it's own when there is a temperature difference.
generally such systems are implemented with a method of collecting the heat, such as a solar-thermal reflector.
but they work on their own just as well.

heat on one side of the system creates a pressure difference and the fluid circulates to balance this out.
flow control valves can adjust the rate of heat transfer, by controlling the fluid rate through the radiators.

the difference in pressure is directly related to the difference in temperature, therefore, usable energy can be taken from the interface.
in a metallic junction a similar thing can occur at the electrical interface.

you have to think in terms of potential difference,
place your house (or whatever you want to climate control) in-between the two temperature reservoirs.
the efficiency of energy conversion is extra on top of the free climate control. so whatever the % is, its' free (or renewable) energy.

here is a drawing of two sterling engines.
what some of you may not know, is the sterling engine not only runs on Heat,
but can also run on "cold".
meaning, the engine can transfer heat from the ambient to a cold source.

The operation of a sterling engine, from hot to cold, or cold to hot
depends on the location of the Displacer. (Yellow on the picture)

In the top example, heat applied to the Heat Exchanger (Grey)
  causes the working fluid to expand, actuating the piston.
the displacer on the cold side allows for decompression and cooling of the gasses in the chamber.
this lowers the pressure on the hot side and draws the piston back, compressing the fluid and the cycle starts over.

In the bottom example, cold applied to the Heat Exchanger lowers the pressure on the Cold side, causing more pressure on the Hot side.
actuating the piston towards the cold side, actuating the displacer so the fluid does not compress and heat up.
this lowers the pressure on the hot side, drawing the piston back the other way, compressing the hot-side fluid and the cycle starts over.
in this manner, the engine absorbs heat from the surrounding air and transfers it to the cold source.

in both examples, usable work is being drawn from the temperature imbalance.

using both types of sterling engine at the interface between Hot and Cold reservoirs, respectively
allows for a central 'buffer', or middle-point between the two temperatures.
the total power is the same, because change in T = 1/2 for both engines.
increasing or decreasing the rate of heat transfer (RPM) on either engine, allows you to control the temperature of the buffer zone.
This zone could be your house, or your car... think of what we do now. we just use ambient heat from the car's engine, to heat ourselves inside.
we could be drawing off the potential between the cars engine and the outside temp. creating usable energy, maybe to power some of the car's electronics.
