A crystal should ideally have very low entropy. Ice has a lower entropy than liquid water and much lower than, say water vapor.

Furthermore if, per Shannon, information is entropy, then a mouse should have much higher entropy than a crystal as it takes many more variables to describe the mouse than the crystal.

I'm not sure I believe Life has less entropy than non-life Loki Liesmith Jan 2019 #1

Plus heat flow, and chemical energy, from thermal vents powered by the Earth's internal heat muriel_volestrangler Jan 2019 #11

Correct, I should have said heat and radiation *on a planetary surface/ocean* is the best candidate. eppur_se_muova Jan 2019 #12
