SolarCity, like Tesla Motors, benefits from Elon Musk being behind the scenes. But, as my interview subjects – Tesla's Anil Parany (whose card I lost and I know I've misspelled his name. My apologies) and SolarCity's Ben Tarbell and Jim Brady – make clear, a SolarCity roof like the one on display can benefit anyone who can plug in a car. The roof will be sold as an option with the Roadster as well as on its own. Listen to the full story here (8 min, 5.8 MB)
At the end of the clip, you can hear Anil wish Martin Eberhard, who recently "transitioned" from the board of directors to the Advisory Board, well. Unfortunately, he didn't give us any more info on what really happened.
