Tesla's Elon Musk promotes solar roof tiles

Instead of talking about rocket trips to Mars or self-driving cars, Tesla Motors CEO Elon Musk turned his attention Friday night to a more mundane topic. He came to talk about roofs. But like all things Musk, there was nothing normal about the roofs he came to discuss. On Wisteria Lane, the backlot set of what used to be the Desperate Housewives TV series at Universal Studios Hollywood, Musk showed off a new kind of solar roof that will be offered starting next year through SolarCity, the home solar installation company that he is seeking to merge into Tesla. Instead of a massive, unattractive array of solar panels typically seen in suburbia, SolarCity had installed roof tiles that are solar collector themselves on several of the houses that are part of the film set.
