Secretary of Energy
A Nobel Prize-winning scientist turned policy wonk, Chu has enormous clout when it comes to shaping the future of technology. His department received almost $37 billion through the American Recovery and Reinvestment Act, part of which will go toward efforts like developing clean coal technologies and renewable energy. (An example of a project: a $25 million wind turbine blade test facility.) It might just help kick-start the second industrial revolution he says we need to meet the world's energy demands in a way that's environmentally sustainable. --B.K.
