Because of the rules of thermodynamics, in particular entropy, heat rather quickly assumes a form that can't be harnessed to any useful purpose.

Because of the rules of thermodynamics, in particular entropy, heat rather quickly assumes a form that can't be harnessed to any useful purpose.
- bane 13y agoCan you provide an example? I know of a nearby stellar body that gets into the double digit millions of degrees that we harness all the time.
- lutusp 13y agoCertainly -- our sun will eventually radiate away all its useful energy and that energy, although not lost, will assume a form that can no longer be exploited. This shows the truth of the expression "entropy increases over time". Reference: http://en.wikipedia.org/wiki/Entropy_(arrow_of_time) http://en.wikipedia.org/wiki/Entropy_(arrow_of_time)
