Wired - Until last year, Arati Prabhakar worked for the venture capitalists who backed Solyndra, the green-tech firm that imploded in a scandal described by Mitt Romney as an example of the White House’s ”crony capitalism.” Now Prabhakar has a new job, this one in the Obama administration: running the Pentagon’s most important research agency. But being the geek-in-chief requires investing billions on risky, high-tech bets that aren’t so different from Solyndra. (Culture, DARPA)
