I like the idea of a solar charger. Not only is it better for the environment, but there may be occasions when a power outlet isn't available. Jerome Kelty liked the idea too, so he made one. And he shows you how to do it on the Instructables website. He says it only takes about an hour. So how much would it really benefit the environment? Jerome calculated that if you charge your device every other day, it puts about 30 million pounds of carbon dioxide into the atmosphere over the course of a year. And his invention has won a national contest.
