Photos: Competition shines at Solar Decathalon

The Solar Decathlon is a competition to showcase the latest in energy technology, and green architecture and engineering. But the students also managed to have some fun with it.

The University of Texas at Austin used an energy-efficient hot tub as part of its construction.

For the Texas environment, the hot-tub idea is actually practical, according to architecture student Matt Weaver, who worked on the house. In Texas, excess heat is generated that can be used for the hot tub.
