Easing Atmospheric CO2 Levels Using Nanotubes and Sunlight

Easing Atmospheric CO2 Levels Using Nanotubes and Sunlight

(PhysOrg.com) -- Researchers at The Pennsylvania State University have determined a way to use arrays of nanotubes in a solar-based process to convert carbon dioxide and water into methane and other hydrocarbon fuels. Their method may provide a new way to reduce carbon-dioxide levels in the atmosphere—rising due to our planet's heavy use of fossil fuels—as well as produce alternative fuels.
