The next energy source technology appears to be quite near now ( after a half century :-( ). I'd wait a while to see what Rossi's ECAT technology, Nanospire's sonofusion devices, Blacklight Power's hydrino technology and a dozen other technologies on the horizon will occur. I'm quite sure that all devices from cell phones, vacuum cleaners, jet aircraft and cars will be entirely self contained with no charging or refueling required. These technologies are imminent in a relatively short time. ( We know for sure E=MC^2, it's just an engineering detail how to convert a microgram of matter into gallons of equivalent fuel. ).
It'll be the end of the petroleum industry, power grid, and many others.
Aside from the possibility of Panasonic becoming a battery supplier to others in the reasonalby near-term, what happens WHEN (not if) the next vehicle battery technology begins to emerge? The range problem facing electric cars is still a key obstacle to broad adoption. Some large and small companies are working hard and fast on fixing that. LI batteries are just a step on the path toward the power source needed to allow the EV market to really take off. One question would be how fast could this factory be converted to a next-generation battery manfacturing technology as it becomes viable?
It is going in Reno Nevada, I live there, they have already cleared the land for the pad for the building the past month.
Unfortunately, they could backtrack and pick a different state, they are expecting the state to throw in 10 percent in concessions/taxbreaks/cash/improvements. Thats 400-500 million. The most Nevada has ever conceeded was to an Apple server farm last year in the same desolate business park and that was 89 million and the legistlator passed laws to never do that again apparantly.
Texas is the only state that could bribe them with that kind of money.
Apparantly Musk tweeted to the Nevada governor: "The ball is now in your court"
