Alternative Energy Forums

Hey everybody, I've been trying to conduct some research on the internet for information related to an idea I have based around the battery-free flashlight technology (the one you shake for a minute and get a few minutes worth of LED light.). Anyways, I've done as much googling as I can and have not found any sites with simple explanations and easy to understand pictures to describe how it works overall. Let alone the basic concepts of creating electricity through the use of magnets. If anybody can explain or direct me to a site that could easily explain the methods of how it works I would greatly appreciate the help. Hopefully once I grasp a full or partial understanding I hope I may be able to share more of this as I have alot of questions I would like to ask (in the Free Energy forums I believe) and improve a basic design into something more relatively useful. Thanks in advance for any help.
