An individual walking the roads at night indicates an invention he is working on produces 55KW with 70KW of thermal energy supplying it. The cold side is at 40C, the hot side at 1650C. Is this something to consider further? Explain.
Let's see if the claim is consistent with the laws of thermodynamics. If it isn't then this invention can't possibly work and wouldn't be worth considering.
Assume that after the engine starts working a steady state situation is reached with the conditions as described in the problem. This means that all thermodynamical variables should remain constant on average. If the engine contains moving parts such as a piston then after one cycle is completed the engine should return to the ...
We use the laws of thermodynamics to investigate this claim.
