A high schooler combined a peltier tile, aluminum tube heat sink, and LEDs to produce a flashlight powered by the heat of your palm.

Interesting.
I'd love to see some science data behind this stuff. And maybe how it would work in Canada.

That is neat!
Enki, I would suspect it would work quite well in Canada, as you guys get over freezing like five days a year or so, right?

Very interesting idea and I could see this as a actual flashlight concept if they fine tune everything and maximize output somehow. Kids sure are smart these days.
Reminded me of this. Saw her on Conan a while back.

It's actually only 3 days.
We're all so hot that it wouldn't really matter anyways though!
