The Fusor
The Fusor was invented by Philo T. Farnsworth in 1964. It works by passing electricity from an outer grid of wire to an inner grid of wire. This creates positively charged atoms at the outer grid and negatively charged atoms at the inner grid. Since opposites attract, the positively charged atoms at the outer grid are shot towards the inner grid. The atoms move at a high speed toward the inner grid, but when they get there they don't hit the grid but go on by it. When they do this they collide with other positively charged atoms, and fuse, creating Helium and neutrons. These neutrons collide with the sides of the Fusor and are absorbed creating heat. This heat is used to boil water. The steam it creates powers a generator which creates electricity.
