I have a generator design that will solve global warming!?

It's called a perpetual motion machine (I think) that generates energy. Its a magnet in a tube bent into a circle. Then four or more other magnets are placed at various angles that push the magnet around the circle continuously. Everything says it should work but im only 14. Does anyone have any websites, or any thing of the like that i can contact to get some help? Please reserve your comments about how it's immpossible if you wanna prove me wrong help me out so that I can build it and see its not gonna work.
