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.

I've just started work on my ambient heat engine. Any comments will be most welcome. See here: http://johnparlour.wixsite.com/free-energy

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.
