Compression heat to power a stirling engine
Compression heat to power a stirling engine
(OP)
Good day, I am an IT engineer in Namibia, but I am very interested in alternative energy solutions. I have done a bit of research regarding stirling engines, for me it looks to be a good alternative for energy production. I am not sure if this is the correct forum to discuss this, it would be great if anyone can point me to the correct person / organization to discuss in full detail and to develop a viable solution.
The drawbacks though are the fuel sources, you are still limited to fossil fuels and energy sources that are not permanent. I was thinking about the possibility to produce heat for the stirling engine with a high compression piston. I have read about diesel engines and how high compression pistons work. It looks to be that the heat created by compressing the air would be sufficient to heat up the stirling engine.
If it would be possible to channel the heated air through the exit valve of the piton directly to the stirling it would run? This way the stirling is not drawing any energy direct from the source, but rather using the energy released. In turn the stirling running on the same cam shaft as the high compression piston will provide the power needed for the high compression piston to keep on running.
Yes you would need a starting system to enable the machine to run long enough to heat up the stirling, but from there it should run by itself. I am looking to get in touch with interested parties to develop such a solution.
Your comments and advice will be appreciated.

RE: Compression heat to power a stirling engine
Your proposed system resembles a perpetual-motion machine because it requires more energy to compress the gas than can be released from the Sterling engine from that compression.

As such it fails on first principles.

Sadly in this life and universe, you can't get something (energy out from the engine) for nothing ( no energy source). This is even more fantastic than a perpetual motion machine which simply keeps going round for ever without stopping
I can only suggest you read something like this https://en.wikipedia.org/wiki/Stirling_engine
It has options for use of heat from e.g. solar array.
A key element is that it needs v high temperatures to work efficiently, at best is only 50% efficient (better than IC engine) and therefore needs constant energy source to work.
All the units need heat dissipation to work to cool the hot gas and hence this heat needs to be replaced.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

No one in over 200 years has been able to break them. You are not going to be the first.

RE: Compression heat to power a stirling engine
Actually your heat could come from any heat source. I would say that the big advantages would be that e.g. fire wood could be used and still achieve a high efficiency. Actually solar heat could be used too.
