>>14218302I have a master in physics you dunning kruger retard, you dont know the first thing about thermodynamics. The most efficient heat engine must always dump some waste heat to the environment, you cant just turn all the heat into power. This is a physical fact unrelated to engineering.
Every coal plant dumps heat into the air or into a river or the sea. Ideally it should be as cold as possible, if its still warm and you try to "recycle" the heat it means your efficiency was too low on the first pass.
