Texas Never Ceases to Amaze Me

The mayor of Austin Texas has an unusual transportation, energy and pollution solution. The mayor's plan is to significantly increase the number of electric cars in Austin, then while the cars are parked during the day they will be plugged into the power grid and sell power back to the city when it is needed and charge the cars when it is not. This will allow Austin to purchase much more of it's electricity from wind sources, currently not possible because wind generators produce the most at night when it is not needed. Electric cars could charge at night with wind power and then provide power to the grid during the day. This may be a far fetched idea but it makes sense, the technology is available and it has support. The only major obstacle is the auto industry which doesn't mass produce an electric vehicle anymore.
