The Pullight Dynamo concept is but a flashlight powered device that relies on stored kinetic energy built up from pulling a string. Sounds like those old children’s toys, eh? What powers this would be a dynamo consisting of a 3-phase motor that helps deliver more power from as little kinetic energy as possible. The Pulllight Dynamo is able to power a cell phone or iPod if the need arises, and is waterproof, making this the ideal emergency gadget to have in every household. Ah well, if only this concept could be realized.
