"Almost all the solar energy is stored in water splitting," Nocera told the inaugural ARPA-E conference on March 2.

SILICON BLADES: Novel silicon microwires can harvest nearly as much light as traditional photovoltaic wafers, with just one percent of the total silicon. Image: Courtesy of Harry A. Atwater Enough sunlight bathes Earth's daytime half in an hour to meet all human energy needs for a year. Sadly, there are several problems with meeting human energy demands by tapping such abundant, free solar power —not least of which is the cost of making semiconducting material that can cheaply harvest the power in sunlight.
