A positive development, sure. But 80MWH is a little less than the amount of energy a 1GW power plant produces every five minutes. I want alternative energy to work, but it's sobering to see the scale of the problems involved. It doesn't seem to me that laptop batteries scale up so well. If I were forced to place a bet on the future of grid-scale storage, I'd look for something else.
