Tesla CTO J.B. Straubel is so full of knowledge that listening to him discuss batteries, battery history, Tesla's mission, clean energy and a carbon-free energy future is not boring, but rather eye-opening.

Here's the video description:

"JB Straubel, Tesla Motors' CTO & the man behind the startup's major technical advances, tells us his electric mission to make our entire energy usage carbon-free."

Enjoy!
