EVs should be made so they stop moving on a cloudy day or when the wind is not blowing.
There has recently been a breakthrough in Li-S batteries that promise about 2.5x greater battery capacity than the current crop of lithium ion batteries.

They will even stop on sunny, windy days when the battery is dead.
I always wonder at the overall net advantages of electric vehicles.
-When there is a WILDFIRE and the power company pulls the plug how do you EVACUATE with a dead electric vehicle?
-When that big push to electric is successful who will UPGRADE the electric grids to meet the demands?
-Is electric vehicle not simply MOVING the pollution from one location to another?
-Add the recycling, or lack of, considerations of all those batteries.
-It takes energy of some sort to generate electricity, water, wind, fuel, nuclear but always one or the other.
-Copper to transmit that power or batteries to store it.
-Is it really all that efficient if you take it all into consideration?
-Will EV's really deter global warming?
(there must be a formula that relates BTU's to KW's)
