I keep reading comment after comment on the internet about how Tesla had designed a machine that would provide free electricity worldwide and it was stopped and silenced by the big money energy companies and is still being kept hidden today. Do any of you know what the design of Telsa's they are referring to? If they have the expertise and education they boast online, then it cannot be the "Lightening Machine." That idea was what led to Marconi developing radio frequency communications, but the idea that usable household and industrial electrical energy could be transmitted that way has been proven false. The idea that it can be transmitted wireless with any usable amperage SAFELY is a failed idea. I had an idea many years ago about building giant underground capacitors and connecting them to lightning rods with giant rectifiers and they would store vast amounts of electricity to be fed to the grid. The fallacy of this idea isn't hard to spot. So what big secret and discovery did Telsa make that our genius minds working to develop clean alternative energy cannot figure out? To date, there is no cleaner, efficient, and safer way of producing AC low loss dependable electricity 24/7 than hydro. I often think that all the energy that Old Faithful and other steam holes generate should be harnessed for electrical power. Remember Telsa discovered AC electricity and how to use magnetic coils to produce an alternating current that could be transformed into a higher voltage for long-distance travel. DC can never do this without great losses.
