Fusion to Electricity
This is the big one. This power plant would not be limited to just hydrogen but could use lithium or helium as a fuel. The basic idea is to make a crater like the one made at bikini atoll, and over time lower weight from the top down to the bottom of the crater while gathering the gravitational energy and converting it to electricity. Building a crater at or below sea level would provide the best weight energy as ocean water would flow freely through the system then at a good rate. Once the weight is out of the cavity it could be used for lowering weight down and gathering the energy perhaps with 90,000 lb., 24' x 4.5' pools or using the ocean PSI against an 8' diameter turnstile / pipe system. The systems used for retrieving the energy could be built outside the crater on tremendous springs to absorb shock energy from re-blasting. The military builds huge underground safe haven bunkers on springs this way to protect them from damage. The time it takes to retrieve the energy would be much quicker than a dam where you can only take out the total weight of the river flowing into the reservoir otherwise you would drain the reservoir! By using the ocean instead of a river you can gather the energy out as fast as you want. Also a dam like Hoover dam takes up about 271 square miles of land. This system would only take up about one square mile of land. The energy retrieved from this system would depend on the efficiency of blast and heat energy to weight displacement energy. When an explosion is set off in the ocean at a certain depth all the energy is converted to weight displacement in a tidal wave. It’s like a big bubble of energy flattened down by the tremendous weight of the water which is pushed up so that it spills onto the land. It’s interesting to note that you could gather the same energy from a crater made by a meteor the only difference is a meteor crater is momentum energy converted to weight displacement.
