Their menorah is four feet wide and four feet tall, made of plastic and spray-painted gold. The lights are nine compact fluorescent bulbs. A cable connects them to a car battery. Another cable connects the battery to a wind turbine with a two-foot propeller.

The next part, the how-it-works explanation, sounds like "The Music Goes Round and Round," except that what comes out is not sound but light. The propeller turns a generator that generates current to charge the batteries. They provide a constant current and voltage to the compact fluorescent bulbs, which give more light on less power than incandescent bulbs.

Mr. Stauber said he saw symbolism in the project. "In the miracle of the menorah, they got back to the temple and there was only enough oil for one night, but they made it last eight days," he said. "I see an analogy with the world's fight for sustainable energy, to take that and make it last as long as we're going to need it."
