Exploiting both types of radiation could be the key to making solar power competitive with fossil fuels
Though the sun offers us a couple options for exploiting its energy -- light and heat -- we've always had to choose to use one at a time, because solar-energy technology hasn't been able to capture both typs of radiation simultaneously. Stanford researchers say that's about to change, however. Their new breakthrough could put solar power on par with oil, price-wise.
Using readily available materials, a team of engineers has come up with the first solar technology to combine photovoltaic and thermal electricity generation.
