Pilgrim Power Station is a nuclear power plant located in Plymouth, Massachusetts. It blends with the landscape like a Hawaiian shirt at an undertaker's convention. Whatever it costs. Let nature take its course. To illustrate his point he produced a child's pinwheel from his back pocket.
Power plants work pretty much the same way.
Now, there're a lotta ways I can get this thing to spin. I could use wind, moving water, or steam. Steam is the most popular method because it can be created anywhere you have a source of fuel and water. That's why most of the world's power plants rely on steam to spin the turbines. Pilgrim's power source comes from fission.
