EDvent Calendar: Day 15 (I've got the power)

My gift to you today is the gift of inspiration. Two amazing stories centred on generating eectricity: first William Kamkwamba talks about building for his village in Africa a water pump and a wind-powered electric generator:
"I found a tractor fan, shock absorber, PVC pipes. Using a bicycle frame and an old bicycle dynamo, I built my machine. It was one light at first. And then four lights, with switches, and even a circuit breaker, modeled after an electric bell. Another machine pumps water for irrigation."
Watch and be inspired:

Second, Justin Hall-Tipping demonstrates a material that allows us to generate electricity using our windows. Truly remarkable.
