Ok I am building a project for my Physics class, and I would like some ideas. What I have is an insulated enclosed container, only about 1’x1’x1’. Inside the box, I am trying to produce as much heat as possible, as efficiently as possible. I have a rotating wheel inside of the box, so I would like to use that to produce the heat. The wheel doesn’t have much power so it can’t do anything too extravagant. I was thinking about maybe setting it up to generate electricity which would produce heat. Any kind of friction would… Oh one last thing, I don’t want to use the sun or anything like that, but I’ll take anything to build off of, Thanks!

... this should be in the off-topic section, can a admin move it?
