generater with the ability to rejuvinate its own magnetic charge and produce enough current to power a 60watt lightbulb for say, several years or longer? Imagine a group of these NPMD boxes hidden under your floor or in the ceiling powering all of your lights, possibly even 120volt outlets for standard appliances. The possibilities are endless.

When I imagine that I see a perpetual motion machine - the impossible to achieve in real life answer to all energy problems.
Because of losses due to heat and friction you always get out less than you put in. That is why it will not work. The number of people who suggest these kinds of machines is, unfortunately, endless.

In order to power a generator you're going to have to bleed off some of that energy. Those opposing magnets each have magnetic fields to them, the two together combine to make a completely different field. It would almost be like a spring. You stretch it and release it, it oscillates for a while then comes to rest. That's just under the presence of friction.
It boils down to conservation of energy. You can't get something from nothing. Eventually all that kinetic energy you put in to start that generator is going to be gone and you'll have to do it agian.

It will probably last a while, but not indefinatly. If you were to hook up a solar powered motor to it as well, it may work indefinatly...
