Yeshiva University students create wind-powered menorah for Hanukkah

wind powered menorah

Raffi Holzer and Mark Stauber, physics students at Yeshiva University, wish to celebrate the Jewish Festival of Lights (Hanukkah) in their own unique way. They have made a wind-powered menorah, i.e. a four-foot-wide and four-feet-tall contraption made from plastic. Flaunting a spray-painted gold outer surface enlightened by nine fluorescent bulbs, the menorah has an attached wind-turbine with a two-foot propeller.

Where a cable connects these bulbs to a car battery, there is another connecting the latter to the wind turbine. The contraption produces light as “the propeller turns a generator that generates current to charge the batteries.” Without consuming more electricity than incandescent lights generally do, the menorah’s fluorescent bulbs utilize a constant current and voltage. The car battery stabilizes any fluctuations caused by the varying wind speeds.

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. 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.

It “worked for eight days” in the miracle of menorah. However, the duo wish to make it work forever.
