Advanced Energy Efficient Greenhouse Systems Using Spectral Splitting and Solar Water Purification Profs Benard, Klausner and Runkle at MSU will work with CU Boulder engineers on a $2.45 million grant from the NSF/USDA INFEWS program to develop and test a new greenhouse concept using a material that splits sunlight into photosynthetically efficient light and repurposes inefficient infrared light to assist in water purification. The effort will lead to a new greenhouse system with reduced energy and water consumption with a potentially large increase in crop yield.
