    When I give classes I'll break out a solar panel show the students the wires in the back and just say "The sun hits the panel, the electrons get excited, they bump into this silver bar and poof they fly out the back"

    Solar is pretty basic, we could use quite a bit more of this free energy source in the U.S.
