Use the PC's heat to produce electricity

Hi guys,

I wondered if there is anyone with knowledge how to use the sometimes up to 70°C heat of the CPU or just the heat that comes out behind the PC to produce electricity. That would be a project which really interests me.

Cheers,

Alex

what like a biolite? you'll need a very large temperature difference to produce what little energy would be reclaimed through temperature differential.

The only thing I can think of that would allow you to accomplish this is a TEG and those things really don't produce much electricity at all. At best maybe you'd be able to get enough electricity to generate 2 watts or so

Make sure to quote me or tag me when responding to me, or I might not know you replied! Examples:

Interested in computer architecture? Still in middle or high school? P.M. me!

 

I love computer hardware and feel free to ask me anything about that (or phones). I especially like SSDs. But please do not ask me anything about Networking, programming, command line stuff, or any relatively hard software stuff. I know next to nothing about that.
