______________________ Cjad the Nord __ Well those students really got beat to the market. I have several flashlights that have small magnetos inside. One minute of shaking will light a super bright LED for two hours, not sure of the energy in to energy out curve. These have been marketed by Atwood as a boating need for five years, retail around five USD.
Details: Coil around a tube, Magnet inside of tube with rubber bumpers at each end. As the magnet passes through the coil an Electric current is generated then rectified and stored in a NiCad Battery.
