Modern gasoline engines have an average efficiency of 20%. Say you put 100J into one. 20J of useful work will be produced, and 80J of heat. Now if 30% of that heat were captured, that's another 24J of useful work. In effect, we've doubled the engine's efficiency from 20% to 44%. That's pretty dramatic.
- StavrosK 15y agoHmm, where are you getting 30% from? The paper says 0.004%, if I understand it correctly.

- StavrosK 15y agoOh, I think 30% is the theoretical maximum. He says they can reach 3% with years of work. It would be great if they could achieve 30%, but I doubt it.
