and fission). The most original inventive step is the pre-cutting/drilling method which can be read about in paragraph 27 of the body of the patent. Any use of this method of digging, for example to build the type of power plant described in the drawings, would be prohibited without their permission, and they could therefore collect royalties from its use to create other systems and the profits those systems create. You may recall that cratering for energy was attempted in the 1950's in the sedan experiments and abandoned because of disappointing results. Two methods were attempted, one was underground the other surface. The efficiency's were .1% and .4% respectively. The earthquake caused by underground blasts and the ugly amount of radioactive material thrown into the air by surface blasts, ended these experiments as viable sources of energy. The method of pre cutting is entirely new and the primary selling point of this whole patent. I HAVE done the experiments and I DO KNOW THAT IT WORKS. Underground blasts caused earthquakes because the expanding "balloon" of energy if you will, had no place to escape and spread out like a wave through surrounding rock. My experiments with pre-cutting PROVES, without a doubt, that the expanding bubble of explosive energy will push that pre-cut piece of material out, with very little energy being transferred into seismic, most into weight displacement,and some into heat, and some into sound.
