I followed EESTOR closely for years. Someone should make a documentary about that saga. Amazing mix of inventor hubris, Canadian OTC pump and dump and a rabid online community of true believers mixed with speculators. Hard to believe that Kleiner Perkins invested in it.
Amazingly they are still around although they have rebranded and are now chasing some other unlikely scheme. It seems there is a limitless supply of suckers for these OTC deals, regardless how borderline their claims or history.
Some of us remember prior generations of battery breakthrough claims like eestor: https://en.m.wikipedia.org/wiki/EEStor
