Lightning in a bottle.
That's the battery.
Corked and on demand.
But for all the talk that batter powered cars are our future, why aren't we driving them?
Think about it.
What are the batteries you use every day?
The rechargeable lithium ion ones, right?
The ones in your phone or computer.
People are obsessed with how long these last.
But car batteries, who's pushing for them to last longer?
The battery-powered car with the longest range in the U.S. is the 80,000 Tesla S.
That lasts about 265 miles before needing to recharge.
The second longest, the 30,000 Nissan Leaf, last about 84 miles.
The average range of a gas-powered Toyota Camry, 476 miles at a sticker price under 25,000.
For all the talk of being efficient and ecofriendly, gas-power still wins on what matters most for people: price.
That's because car batteries are expensive.
And while Elon Musk claims his plan the gigafactory will mass produce lithium ion car batteries, and lower their costs by 30 percent, will that be enough to power our driving future?
Maybe in the short term, but some researchers believe that in order to be truly transformative,batteries need to evolve into something completely different.
