@aevin the power it generates is so tiny it's useless tho

@feld @aevin Also, in theory, maybe tech based on temperature differences could be an extension of passive energy, like recouping some of the energy lost when heating buildings in the winter.

@scribe @aevin max solar energy hitting the earth is 1367 W/m2

This tech is 25 mW/m2, or .025 W/m2

First pv cell was made in 1883 and was 1% efficient, so 13.67 W/m2

So yeah this is worse than tech from the 1800s and has no real room for improvement
