Steam Electric Generator

This is still a thought in progress.....but here is the principle... Imagine a tube ten feet high and about 6 inches diameter, this tube is wrapped with a coil. the tube is filled with water. Inside the water is an inverted cup shaped magnet, about 5 inches in Diameter. The magnet is reasonably aerodynamic. There is a bulb at the top of the tube, and a bulb at the bottom of the tube, large enough to allow the magnet to rotate.

Here is the principle. The magnet starts on the base of the tube, with the open space to the bottom. The bulb is heated, and the magnet traps air and rises to the top. In passing the coils, electricity is generated.

At the top of the tube, there is a hook, which catches the magnet and causes it to flip, releasing the air, and sinking to the bottom. On its way down, it again generates electricity.

At the base, there is a second hook, causing the magnet to flip back to its original position.

I have totally forgotten the principle of boiling water, and suspect that I need some technique for introducing air at the base of the tube....like I said, this is a work in process.
