Here is an image captured from the doughnut-shaped test reactor at MIT. This magnetic fusion reactor fuses two heavy isotopes of hydrogen to produce helium and a blast of energy. In a working power plant, the heat from the making of helium would be fed back into the reactor to sustain the reaction. The other product of fusion is neutrons which fire off after fusion. The idea is to convert the kinetic energy from those neutrons into electricity by making steam, which would drive a turbine as today's power plants do.
