Re: Stirling Engine & Heat Pump

I agree, the temperature difference is key. Looking into the efficiency ratings for Stirling Engines I can see my target of 50% efficiency is currently unrealistic. My goal won’t be to use the configuration to produce anything more than a self-sustaining heat pump with a useful heat output . With a ...

Re: Stirling Engine & Heat Pump

Thank you for these links, I will give it a try. The physics forum link wasn’t helpful as they seemed to equate the configuration to a ‘free lunch’ or perpetual motion machine! There was also a claim about it breaking the 2nd law of thermodynamics, all of which demonstrated a lack of understanding a...

Re: Stirling Engine & Heat Pump

If nobody can suggest a reason why this wouldn’t work, I’m going to go ahead and try it. The implications are too far reaching to ignore and I can’t think of a reason why it wouldn’t work. I also asked the same question on the “Just have a think” YouTube channel and, so far, nobody has responded. It...

Stirling Engine & Heat Pump

If a heat pump has a COP of >3, could a Stirling Engine use the heat energy to both power the heat pump and generate additional power? EG Heat pump requires 1KW to salvage a further 2Kw from the environment, resulting in >=3Kw output. Therefore 1Kw input to heat pump and 2Kw available surplus. Even ...
