These students came up with a great solution for expanding their wireless network. Apparently there wasn’t any power source available for the network repeater, so they build a wind turbine. These should be on every rooftop, in every city.

Dan built the charging circuit himself. Essentially the windmill recharges two 12V batteries and the circuit exists to make sure it does not over charge them. The wireless AP/repeater (not in the picture) is connected to the battery terminals. We “waterproofed” it using plumber’s putty, the plastic tuperware box, and that metal box that Dan got off ebay).
