On the surface of a new photovoltaic prototype, microscopic nanotube towers perform best when they catch light on their sides.

I’m MIT Technology Review's chief correspondent, keeping an eye most often on the world of information and communication technologies—and asking my kids when I don’t understand what’s going on. Recent projects have taken me to Kenya to write about mobile-phone-based health initiatives, and Germany to explore how they’ll ramp up renewable power while closing down nuclear plants. My 2008 feature on the Obama campaign’s social-networking operation was selected for The Best Technology Writing 2009.
