And of course theres the obvious non-sequitur. Many in the car industry believe the range needs to be close to 500km and the cost around $100 per kilowatt-hour before all-electric vehicles will move into the mass market. That would also allow smartphones and laptops to run for days. Right, if batteries get cheaper, my laptop will run longer.
