crank windup torch

I purchased two crank charged (wind up) lights at the dollar store. When I got home I realised that one had been opened and tampered with. Considering what I paid for it I decided it would be more fun to take it apart and see what is in it than try to return it. I found what I thought would...

Anyone have a windup torch? Would you surmise that a powerful maglite with reserve batteries beats this option? Are you stocking batteries? What's better? Is there a solar torch? :D: I have a Durapro, with radio, that gives off a blue light. A minute's crank gives about 5 mins strong light, 10 weak.
