The University of Colorado at Boulder will be one of three schools featured in an in-depth look at the 2007 Solar Decathlon competition by the Discovery Home Channel/Planet Green network. The one-hour program, called “Solar Showdown,” will air Monday, Dec. 17, at 6 p.m. MST and again at 9 p.m. MST on the Discovery Home Channel, a digital cable-only network. The show is expected to air three more times on Dec. 18 and is part of a preview of the new Planet Green network, which will replace Discovery Home in early 2008.
