Hi,
Honestly, the title of these boards should change because it gives some people the wrong idea that it's about using heat (a heated object) to capture energy. It's about capturing ambient thermal energy that exists in *all* matter, and does not require a temperature gradient.
Please change:
From "Heat to mechanical energy conversion" to "Ambient heat to mechanical energy conversion"
and
From "Heat to electric energy conversion" to "Ambient heat to electric energy conversion"
Regards,
PL
