This country needs a "manhattan project" to create the next new battery technology if we're ever to get to electric vehicles. (And I know a few people at Argonne National Labs, 30 minutes from my home doing just that. Even they say it'll take years, perhaps decades to achieve.)
Unless a new major breakthrough comes along that enables high voltage/high energy batteries used to propel electric vehicles and recharge them within minutes comes along, we're sure to see the end of electric vehicles.
