And, depending on the radio wattage required to sustain the reaction, there is always the possibility that it can burn hot and long enough to fuel more energy than it's taking in. I know that defies physics to some extent, but have we ever thought just how MUCH FREAKING ENERGY possibility there is in a glass of water? We're thinking about energy into the equation in terms of just the radio wattage, not the energy required to manufacture the radio in the first place. There was the theory that a glass of water had the ability to power a city under the right circumstances. Here we have a test tube of water burning for two full minutes. Imagine what a 55-gallon drum could do...
