Time for an Energy Storage Geek Out! The most requested Geek Out on FeatHub as Battery Technology, Carl and Richard discuss a wide range of aspects of energy storage. The conversation starts out on electrochemical batteries, which are only about 200 years old. Richard digs through the technical aspects of anode, cathode and electrolyte, dry cells, wet cells and polymer cells. And why do some batteries explode, anyway? Then the focus is on Tesla's new PowerWall battery products, what they're good for and what they aren't. And before the end, some other storage techniques like superconductors, ultracapacitors and flywheels!
