Maine farmer Posted October 28, 2017 Report Share Posted October 28, 2017 Yes, it's the hypothesis in my mind. I'm just trying to prove it.I always thought it best to try to test a hypothesis rather than prove it. Attempts at proof or disproof may leave one more open to confirmation bias.

They use either slightly modified internal combustion engines or, far better, fuel cells. Fuel cells have the advantage that they are not limited to Carnot Cycle efficiency constraints, as they are not heat engines. In theory I understand you can get 80% efficiency from a fuel cell conversion, though in practice 40-60% is the most that seems to be achievable.

Correct, My intention is to explain, that Carnot Cycle doesn't play outside classic heat engines. Quote Link to comment Share on other sites More sharing options...

What is your point, though? Is it that your proposed detonation engine is not a heat engine? Could be I suppose, but how would you argue that?

Maine farmer Posted November 4, 2017 Report Share Posted November 4, 2017 Well, there are already proved hydrogen vehicles, produced by Toyota, Honda and Hyundai:https://en.wikipedia.org/wiki/Hydrogen_vehicleYes, but I believe those are fuel cell systems and not combustion or "detonation" engines, and who is buying them, or can afford them? My old VW diesel is in the shop for repairs to the body, and I started researching possible replacement options, and I am coming to the conclusion that my best option is to keep patching my old diesel.
