Vinod Khosla, Silicon Valley venture capitalist, says he used to be an environmentalist, but is now more of a "pragmentalist." In this Stanford Center for Social Innovation sponsored audio lecture, Khosla turns conventional wisdom about what passes for "green technology" on its head. He takes a hard look at how innovations such as hybrid cars and fuel cell buses may, in fact, be exacerbating our problems, and offers concrete, iconoclastic suggestions as to what science, business, and government should be focusing on instead.
