There was also a 100x breakthrough back in 2009, although I don't know whatever happened with that one. Battery breakthroughs seem to happen frequently, but seldom make their way to market.
Very curious to see what Imeo has up his sleeve here. Although I can't help but tilt my head, a bit puzzled at the thought of it. Batteries are a huge industry (with a lot of liability in the Lithium segment because of their destructive power). Imeo makes the best PV's in the world imho - but getting into the battery business seems strange - a little like hearing that the Ferrari corporation is coming out with their own line of gasoline. heh!
Still though, he says 10440 with 900mah, and my curiosity is piqued to say the least
