PayPal cofounder, SpaceX Founer and Tesla CEO Elon Musk takes the stage today at the Web 2.0 Summit to talk with John Battelle.

What do space flights and electric cars have to do with Web 2.0? Absolutely nothing. Still, there will be lots to talk about. In September SpaceX put a Falcon rocket into Earth orbit, the first privately developed launch vehicle to reach earth orbit from the ground. More recently, his Tesla Motors has gone through layoffs and raised another $40 million, and Musk took over the CEO role. There have also been some spectacular Tesla crashes.
