I have been considering various ideas involving using bar magnets (or other forms of magnets) to construct a crude turbine generator, in order to light a light bulb, or even make a light bulb constantly flicker (the purpose of the experiment being only to justify a concept, and so therefore leaving some light bulb to flicker for days, weeks, or months would be perfectly sufficient for my purposes).

In the image above I have been considering what might happen if an array of bar magnets were attached to a rotor which would then turn a standard coil generator to generate a current to light a light bulb. Now let's assume that such a rotor device would spin. It would light the light bulb. Let's suppose it is unstable and oscillates all the time. It would make the bulb flicker.

I have also been considering methods that could be employed to distribute the repulsive forces in such a way that the rotor would be certain to spin. This would involve spacing the magnets in such a way as to have uneven repulsive forces always present at one pole (one pole is always ‘more repulsive' than the opposite pole, giving that pole ‘more push'). In keeping with the same idea it might be possible to include attractive forces (one side is always more repulsive than the opposite side is attractive, and vice versa). The idea here is to distribute the forces in such a way as to ensure that the rotor keeps spinning perpetually, which turn the coil generator and light the bulb. Even if the speed of the revolutions was uneven this would be sufficient (the bulb would brighten and dim). People would then need to ask what the power source was that was lighting the light bulb.

I have also been contemplating a more sophisticated design, which involves creating a rotating fly wheel incorporating polarity switching magnets (which I envision then creating a steady and consistent rotation of the rotor, providing a consistent rotation to the spinning coil generator).
