One wonder how implementation of fusion will unfold. Fission reactors where suppose to provide clean, almost limitless energy when introduced. Not much was talked about the inherent hazards of a fission reactor or waste disposal. We eventually settled on a technology that only used 4% of the fuel in the rods was used before they where "poisoned" and had to be replaced loosing 96% of the promised energy. Reactor safety was (is?) not totally understood. What promises for fusion will go unfulfilled, or overstated. Will we just create another "mess" to clean up?
