4 cool tech ideas for green cars and renewable energy

This is the age for big battery claims. We need breakthroughs, and it looks like we’re getting them. I talked to Grant Norton, a mechanical engineering professor at Washington State, who’s pioneering tin-based anodes for lithium batteries. The value of tin has long been recognized, Norton said, but the lack of scalable production methods sidelined it in favor of carbon. But Washington State had a breakthrough, and that production is in sight, potentially yielding triple the energy density, faster recharge times and greatly reduced cost. It’s still at the lab scale, but expected to ramp up quickly, either through a spinoff company or a license to industry. It joins a broad range of other battery tech waiting to enter the market.
