It reminds me of a certain green state that when there population runs low on 240 power ,they rely on other states coal fired power to put the lights on...
The EP Tender is an interesting solution to this problem, albeit not a permanent one. Its essentially a little trailer that you tow behind your EV. If your battery starts running low, the EP Tender kicks into action, turning on the generator inside the trailer. It feeds electricity into the car to keep it going further than would be possible with just the cars battery.
