Just checked and the EEStor site is still up. I thought they had gone under. http://www.eestor.us/index.html
Zenn is apparently still active as well (Canadian- so they probably went through another round of stock manipulation). Despite the UCLA connection to Sunvault and the convincing videos - there is too much which is unsaid in this sales pitch. It can be argued that it is trickery to promote any capacitor design as "graphene" since the important thing for ultra-capacitance is the dielectric, no? Graphene is a conductor, so what is the dielectric being used with the graphene? Please do not say: modified barium titanate. Obviously, graphene gets a lot of good press - "graphene fever" is kinda like "nano fever" of 5 years ago and hydrogen fuel-cell fever before that (Ballard still survives). The pump-and-dumpers of BC are on track to reinvent that same investment fever. EEStor at least did have testable material. Never mind that in a rear-ender, a high voltage ultracapacitor could be the equivalent of a rather formidable bombe, as the inspector would say. Yet --- to put this story into perspective ... recently mentioned here on Vo was the so-called "megafarad" cap ... isn't that one positioned to be a two orders of magnitude bigger bombe? (not to mention, the technology turns out to be already 6 years old but the product is vaporware). The hyperbole and "revised" data of Canadian energy stocks makes Parkhomov look like a choir boy... amazing the DGT could not plug in. -----Original Message----- From: Terry Blanton SUNVAULT ENERGY INC. is pleased to announce that in conjunction with the Edison Power Company ("Edison") that it has successfully created the world's largest 10,000 Farad Graphene Supercapacitor." Building large 10kF capacitors is easy. It's making them small that is difficult. :-) Leakage rate and structural integrity are not mentioned and are the biggest weaknesses in SCap design (as EEStor found out).
