Greenhouse film to convert sunlight into more useable form
Samuel Zeller
University of Colorado Boulder has received a $2.45 million grant from the U.S. Department of Agriculture (USDA) to develop a semi-translucent film that splits incoming sunlight into photosynthetically efficient light.

Under normal conditions, plants only use around 50 percent of incoming sunlight for photosynthesis while the remaining half goes unused.

This cost-efficient, greenhouse material will split incoming light and convert the rays from less-desired green wavelengths into more desirable red wavelengths, with no added electricity consumption. The inefficient infrared light can be redirected to power water purification. | READ MORE
