Wired Article on Energy Needs of the Nation

Wired released a 4 part story today covering the grid, batteries, transmission and lots of related things. I first learned about EEStor from a wired article so I'm a follower of their news. What do I think of this series of articles of theirs? The energy storage piece is not too deep, sorry Vince Beiser. The only super batteries worth mentioning are EEStor EESU's. :-)
