The thing about producing electricity using a thermal engine is that thermal engines have a maximum efficiency that cannot exceed the Carnot efficiency. Example: discard heat at 30 degrees Celsius, use 300 degree Celsius steam, the Carnot efficiency is (1-(273.15+30)/(273.15+300)) * 100% = 47%. That's the maximum that no engine can exceed given the ...
