The sky was heavy and gray. The air was a misty drizzle interrupted by heavy downpours. It was the perfect day to promote solar energy.
The unveiling yesterday of 18 solar-powered homes built by college students on the Mall was not marred by the persistent rain showers. Optimistic, java-fueled students, who had been assembling the homes in Washington for the past week, were ready for the weather.
"We're, like, second behind Seattle in overcast days, so we need to be able to function well on days like this," said Rosemary Lapka, 21, one of the Pittsburgh students who helped design an angular home that resembled a Scandinavian ski lodge.
They are competing in the second Solar Decathlon, a competition in which student engineers, interior designers, architects, designers and others create a small home completely powered by the sun. They must be able to cook meals, run hot water and power an electric car.
"We've got to cook five dinners next week. Including one for a bunch of reporters, so I hope that one is good," said Najahyia Chinchilla, 27, a graduate architecture student at the University of Maryland.
Planning began two years ago, and construction on the Mall started Sept. 29, when buzz saws hummed and drills buzzed until Solar Village, complete with sign posts, mailboxes and potted mums, rose from the strip of land between the Capitol and the Washington Monument.
Some homes were carted here nearly whole; others were assembled largely on the Mall. They come from as far as Madrid or as close as College Park.
"We built this on a steel chassis, so we just trucked it right over," said Matthew Wagner, 24, a Virginia Tech graduate architecture student. "The house did 70 mph on the way over here. So we figured we already proved it can take some pretty good wind."
Some houses reflect their origins. The Florida International University entry is a glass U-shape, decorated with sea grass and tangerine-colored furniture.
"We let the outside in. We created something that looks like a Florida courtyard, something that can be one, big entertaining area," said Robert Perez, 30, a graduate architecture student from Miami.
The house from the New York Institute of Technology looked like a futuristic Manhattan loft and came with a fast-talking PR woman.
The living area has deep cardboard recliners, crushed sunflower hull tables and personal air conditioning tubes to "create micro-atmospheres," said the spokeswoman, communications student Shana Lerner, 25.
