The first decades of a developing technolgy. Most of the R&D on miracle-magnets, miracle-motors, & bombastic-batteries has been 40+ yrs in the making. And a lot of that has been in universities, MIT, etc. Not just by manufacturers. Lots of money has been given in those decades to support that research, including superconductors, as well as ICE refinements. That's not a bad thing, but a factual perspective.
