Back at the office, Richardson shows me a climate-change mug someone gave him. When you add hot water, the places that will someday be submerged by ocean water if Greenland's ice cap melts turn blue. Farewell New York, London, Paris, Vancouver and the entire Amazon basin. Outside the door, Laberge is updating the company's Web site, and the team's plasma specialist, a young postgrad named Stephen Howard, is tinkering with the design of the plasma injector that they are right now trying to decide if they can afford. Richardson shows me chart after chart on energy demand, as well as existing technology that backs up almost everything they're building or plan to build. The global demand for power, he points out, is nearly 4,000 gigawatts today. According to projections, it will be 7,000 by 2030. The world can't possibly meet that number using existing sources.
