Recycling energy: Energy Scavenging Evokation!
Agent NickDutch may be on to something. He says, “We recycle glass and cans and paper. Why not recycle energy?”
This makes a LOT of sense. Most of our energy processes right now are tremendously inefficient; often, they lose energy as heat, and often too this heat requires even more energy to manage. Fuel-powered cars, for example, both lose energy from their fuel as heat, not propulsion, and then lose even more energy because they must force cooling air through a radiator, creating drag. An office building with a large air-conditioning system to cool itself because it is filled with heat-generating lights and computers is another example.
Nick has found technology which can recapture some of this lost energy. Read his posts about Thermo Electric Generators (TEG), Peltier cooling and the Seeback effect, and how this can reduce Co2 emissions (plus information supplied by Agent Daniel LaLiberte in his comment here). Then read Agent Nick’s ideas for an Energy Scavenging Evokation and its implementation based on the potential of this technology and see if you can join and contribute! (What’s an Evokation?)



Yes!
I’ve been trying to figure out how to use my computer’s heat output to power my food dehydrator, for making raw snacks…
I wonder about salvaging all of the left over power from batteries that no longer have enough power to keep my flashlight, radio, or camera working properly but are not completely spent. How can we recycle this power which I suspect is enormous?
