Solar Decathlon (8/10)

The Solar Decathlon in Washington in October 2005. The event saw 18 collegiate teams from the United States, Canada, Puerto Rico, and Spain competing for which solar-powered house offered the best mix of aesthetics, convenience, energy production, and efficiency. Each house also had to produce enough "extra" power to run an electric car. (Photo: Stefano Paltera / Solar Decathlon)
