Episode 46: Charging Up
This week’s image is a publicity shot of the Chevrolet Volt, by GM.
The first cars didn’t run on gas—they ran on electricity. Over a century later, the high cost of fuel has finally forced automakers to take the possibility of battery-powered cars seriously. On today’s show we look at three kinds of batteries that have been proposed as transportation solutions. We start with nickel hydride batteries, the key component of contemporary hybrid cars like Toyota’s Prius. Next, we look at the technology behind hydrogen fuel-cell vehicles. Producer Devin Browne wraps up the show with an exclusive visit to GM’s battery lab in Warren, Michigan, for a close-up look at the future of lithium-ion battery cars. Element of the Week: Nickel.
