I have learned that the company Potenco has released a pull cord generator that is small, and can easily be taken anywhere around the world. To produce the energy, all you have to do is pull the cord and it will generate a little electricity! Then, with only one minute of pulling, you can get enough energy from it to talk on your cell phone for 20 minutes, or listen to 3 hours on the Ipod Shuffle. I can't believe that there are all of these great ideas to help keep our world clean, and yet most people have never heard of them.
