Sunlight has the greatest potential of any power source to solve the world's energy problems, said Nocera. In one hour, enough sunlight strikes the Earth to provide the entire planet's energy needs for one year.

"This is a major discovery with enormous implications for the future prosperity of humankind,"

don't forget the "old school" solar technology; focus the heat to create steam. everything downstream of that is standard mature technology, already deployed all over the world.

Add to that the fact that hydrogen is the most plentiful element in the Universe. Not being a chemist, I would venture a guess that oxygen is pretty high up in the ranking as well, since it supports combustion.

Isn't this fantastic news!!!
