Every two years, teams of college students compete to build houses powered only by solar as part of the Department of Energy's Solar Decathlon. The students not only have to come up with innovative concepts, they're also forced to actually make their ideas work as part of actual, fully functional homes.
The City of Irvine, California, hosted the Decathlon for the first time last October (and will do so again in 2015). The video clip here is taken from a 55-minute documentary the city released recently. It gives a sense of the toil and trouble involved in erecting 19 original homes from scratch, and really, the sheer extent of the event. You just need to excuse the somewhat syrupy music:
Craig Reem, the city's director of public affairs, says the film was made over 32 days, which covers the time it takes to put up the houses, open them to the public, and take them down again. In all, 800 students were involved in last year's event, and 64,000 visitors turned up to tour the designs.
"Our idea was to capture the rock-star status of the 800 collegiate students and to capture the story of their and the Department of Energy’s overall message of accessible energy-efficiency," he says. The documentary is due to be shown on PBS later this summer.
