In this photo taken on Dec. 18, 2013, Boston Celtics managing partner Wyc Grousbeck, left, stands with venture capitalist Bob Higgins, center, and team co-owner Mark Wan, right, during a break in the action at an NBA basketball game in Boston. Grousbeck and a group featuring a dozen of his co-owners in the NBA franchise have invested $21 million into Formula E, an all-electric auto racing series that has already attracted interest from environmental celebrities like Leonardo DiCaprio and Richard Branson. The circuit is scheduled to debut in Beijing in September and continue on the streets from Miami to Monaco in a 10-race, Formula One-style championship.
