So Let's say I wanted to make a machine that rubbed steel

Skip all the steps and take the energy source you'd use to rub the pieces together instead.

So you're saying I could just have the copper and steelwool on top of say a block of lithium with a power outlet and the heat would transfer to the lithium?

ur mum rubbed her steel wool against my copper wire last nite

Well usually heat is converted to mechanical energy through the expansion of fluids, but I don't think you'll be able to boil water by rubbing a copper wire. In your particular case you could probably use the Seebeck effect to convert that heat into electrical voltage and drive an electric motor.

What if I made a copper belt that spun around a steel rod with a cup of fluid at the top?

If you want to waste energy so badly, just run current through a resistor.

Well were else do I put the power I make with my contraption, a tomato? I'm stealing your tomato!

Just take whatever you're using to spin the belt and use that thing's energy source instead.

this was hurtful
