It is obvious that several of you know a heck of a lot more about this than I do but I do have to agree with SA_ORION. Several decades ago my father ran an Auto parts store, part of a chain of 6 stores, in Indianapolis, IN. His store was only a couple miles from Gasoline Alley. The had a customer come in who had developed a carburetor for the then early V-8s that had less than 20 moving parts (New carbs have in the neighborhood of 150 to 200 moving parts in them depending on size). It allowed the engines to get 35-40 miles a gallon. This was in the mid-late forties. Dad said they were selling 2 – 3 a month at most of the stores until about 8 months after they started to carry them. They always had 5-6 in stock in each store. One day each store had two men come in at almost the same time and purchased all they had in stock. Dad found out from the chain owner the next day that all of this type of carb had been bought and these folks then contacted the creator and manufacture and bought all he had ready for shipment, all parts and the blueprints for the carbs. Since he had registered it and copyright protected the plans the buyer (later found out to be Mobile Oil) was unable to reproduce as they had not bought the rights. But what they did was lock everything away in
a warehouse in the industry section of Indianapolis, where they were still sitting as of 1993 which was the last time my dad heard from his old boss who had been keeping track of them.
So, there have been ideas, even products produced that would have been a great benefit to humankind that have been squashed because of greed on the part of a few. Another idea that has been written up several times that I have seen in the past is using Satellites in geostationary orbit to collect solar energy and then beam it to the surface via laser to receivers that would covert that to electrical energy and introduce it into the grids on a worldwide basis making electrical power almost free. That too was stopped as being “too expensive and complicated to pursue”. Yeah, right. For whom? Now however solar panels have gotten considerably smaller in the last 5 years so that a 5Kw system that would have taken up most of the roof space on a 2600 Sq. Ft home
now only takes up about 500 sq. ft. Additionally the cost has come down with it as well. Five years ago that same 5Kw system would have cost $50K, now about $20K. With a projected 5 years to pay off by not using commercial power from the Utility companies and selling them your excess. Here several states have requirements on the books that require the Utility companies to buy your excess energy you aren’t using. So, maybe just putting up your own solar system is the way to go.
In any case, I believe Tesla had the right Idea. One of the cable channels here recently had an hour long program about him, his ideas, and the tower and power generation building he had started to build until he couldn't get the funds to complete it and test it's full capability. Another thing to think about, take a look at the Tesla auto and what it is capable of and compare that against what the big automotive manufactures are trying to sell us and those cars limitations. Doesn't take a rocket scientist to figure out that they are purposely limiting what they are building to increase price and forestall the development of vehicles that won't use or need fossil fuels.
