Body Heat Could Charge Your Cellphone

Body Heat Could Charge Your Cellphone Saw this article the other day, and I couldn't get over the possibilities. As interesting as charging your cellphone from body heat is, think of all the other possibilities. If you live in the North East like I do, you could generate electricity from the lost heat of your furnace or boiler. It is unclear how much power you can generate from heat, but making power generation orders of magnitude more efficient is a pretty huge jump. Power stations being 100x more efficient would sure save a lot of fuel costs.
