If one is to solve the energy demand problems in this country, no one solution will work. The Pacific NW has plenty of hydro electric potential, but is a rotten place for solar. The southwest is exactly the opposite. Tidal energy in Kansas is just plain silly.
A blended approach is necessary, multiple solutions. Might using two different types of batteries make a better solution for vehicles? This custom lithium chemistry for start-stop, and more conventional for regular operation?
The chemistry is beyond me but it sounds good. Why did the battery consortiom fork over millions of dollars for this technology. They could have gotten it much cheaper by going out and playing a round of golf in a golf cart. Golf carts have been stopping and starting for years.
