Incredible Device That Generates Electricity Out of Thin Air

[Selvedina + 39]

This thermal resonator generates electricity by harvesting energy from changes in temperature and it could power gadgets for years. The power source relies on fluctuations in temperature between day and night and electricity is created when one side of the device is hotter than the other. A proof of concept device was shown to generate 1.3 milliwats of power which is enough to power environmental sensors or communications systems.

Great device and very useful when there is no other resources to rely on.

That's amazing. However, I wonder how much it costs compared to a solar panel that powers the same amount of energy.

so how long from proof of concept to commercial viability?? I want one!

I could use a couple, too. Very promising tech. I hope it lives up to the expectations.
