Every hour, the sun beams down more energy than the whole planet consumes in a year. Although solar cell technology has surged forward recently, many challenges related to reliably capturing and storing the sun's energy still remain.


Sossina Haile, a professor of materials science and chemical engineering at CalTech, is developing a new approach to solar power. Using cerium oxide (or ceria), a metal most commonly found in self-cleaning ovens, Haile and her research team have created a prototype reactor that has the power to transform sunbeams into clean fuel.
