Now those are some REALLY SMART batteries to only store wind and other renewable energy. Do they spit out electrons generated at the coal-fired plant down the road? Or do they put up barriers on the wires informing those wayward electrons "Your kind not welcome here"?
The Japanese have a way of perfecting products that are invented in the US. They’re smart(er). They’ll build the plant in Mexico with the HQ in Texas-smarter.
Can batteries be perfected? Wind power would be perfect to fill them up. It’s free. We’re on defense on this one. They’ve got the ‘global warming’ issue on their side.
