Although word of this innovative device has been floating around since last fall, the folks at Treehugger got some footage of the charger in action and some video explanation of the usage and versatility it brings.  The charger uses a pull-string mechanism to generate a 5-watt electric charge each time you pull the string.  The tiny machine is meant to charge cell phones and a wide range of smartphones that are currently on the market.  it was also confirmed that the time it takes to pull the string to charge the YoGen charger  would be equivalent to the amount of charge time for a phone charging in an electrical socket.
