I wasn't exactly sure whether this belongs in the mechanical or electrical section. /watch?v=VsGhllSgpLU&feature=related [STRIKE]That was the video I saw that made me want to start a project. This would be my first, and I haven't taken physics or anything yet, so I don't know [STRIKE]some[/STRIKE] a lot of things. Here's what I plan to do: Create a smaller-scale version of what was shown in that video. One that could fit on a 1 foot by 1 foot square surface and 1 foot high. I want the energy created to be converted to electrical energy and then sent into a lightbulb. This has to be made with limited tools, so no welding. I have access to basic tools. All I really need is a list of materials. If you wanted to make this (under a low-as-possible budget), what would you use? Please be specific for things such as the type of motor. A few additional questions: Would I need the magnets to be in a perfect circle and then tilted either clockwise or counterclockwise? Would it be difficult to get this right? Would the generator be able to go on forever as long as nothing interferes? If I connected a lightbulb, would the lightbulb stay on until either I stop the generator or it burns out? What would the expected energy output be of this generator? Would it even be able to power a small lightbulb?[/STRIKE] Okay, ignore everything above. Would a machine like this even work? What would go wrong? An lastly, for educational purposes, can you explain the science of a generator like this? Where does the energy come from? Doesn't a contraption like this have infinite potential energy? Wouldn't that violate a couple laws of physics? I'm not sure what the physics behind magnets are, but I'm pretty sure magnets don't transfer matter or energy to what they are attracting. So what would the momentum be called if no object exerted force on it? Keep in mind I haven't taken any courses in physics.
