``Licht and his coworkers say that besides besting the solar-to-hydrogen conversion record, their work opens the way to efficiencies not considered possible before. Using measured photoelectric efficiencies of seven semiconductor combinations not yet tested in hydrogen generation, they predict maximum solar-to-hydrogen conversion efficiencies of up to 31 percent.
Thermodynamics theory says the maximum could range above 40 percent for a two-junction converter, but no one has previously predicted better than 24 percent performance for practical devices, Turner says. Experimentally achieving the new prediction `would be an accomplishment indeed!' he adds.
Something is happening, but you don't know what it is, do you.....?

I'll take a wild guess. What is ... Hindenberg, for 200 dollars?
Sorry, but I just couldn't resist.
