crank it up

I was wondering when someone would make the technological leap. Have you seen flashlights that run solely on a crank handle? Or flashlights that store energy after shaking them? Finally they’re putting that tech into toys. Ecotronics is a UK-basked company being sold here in the states via International Playthings. Even without batteries, these toys all have an electronic function to them. Some of the designs are better than others. Mr. Robot Head is my favorite: keep the wand away from the wire antennae or the robot wakes up! Great fun!
