You can convert the electricity to heat but the electrons themselves are not heat. You must go again to school and learn the real physics.

"I believe that all mathematical physicists should be hanged
from the highest trees and telephone poles available.

If the laws forbid this, or it messes up the landscape,
then we should institutionalize the whole lot of them.
But keep in mind that there aren't enough funny farms to hold so many idiots.

I'm so upset that relativists hold the reins of power that I think that I'll
just go and read the newspaper to cool off..."

"Bill Gaede"
