"I'm actually in the market for a new car and would love to buy an electric car," he says. "But there are practical problems."
Srinivasan is driving around the lab's campus in a mini-electric car, sort of like a golf cart. But there aren't many full-size versions that would work for his daily 70-mile commute. The Nissan Leaf goes about 75 miles before it needs charging. Tesla's sedan can go 300 miles, but it's pricey.
"What we want to do is get cars that go 200 miles, but you can buy them for the cost of, say, a Toyota Corolla or Toyota Camry," Srinivasan says. "Where we are today in battery technology, we need a lot more work before we can get there."
