Money.cnn.com had an article where they surveyed a bunch of entrepreneurs and asked them what kind of startup companies they would be interested in investing in. One of those they asked was Elon Musk. Here's what they got. . . Elon isn't the only one interested in storage technology. Next they asked the people at Kholsa Ventures. . . When they say "five times the life", I don't know if they mean five times greater energy density (which would be revolutionary) or merely five times the lifespan before it needs replacement (which would be less revolutionary, but still great).
