The shortcut to doubling solar efficiency?

Super Soaker inventor proposes a solid state heat engine that resembles a fuel cell. The idea is to reach a new level in heat generating efficiency, or at least replace heat pumps, with no moving parts. "Johnson has opened up a fundamentally new pathway to generate electricity from heat," says Paul Werbos, program director for power, control, and adaptive networks at the U.S. National Science Foundation (NSF). Werbos, an IEEE Fellow, says the NSF is funding Johnson's heat-engine research because of the strong chance that it could cut the cost of solar power in half.
