Abstract: A power plant and process for converting gas expanding and contracting energy sources into useful forms of energy and utilizing gravitational force, wherein a piston containing a magnet and able to free fall within an enclosed cylinder, having a non-magnetically-responsive center portion surrounded by an induction coil is repeatedly impelled upwards thereby inducing an alternating electric current in the coil. In the preferred embodiment, a mixture of fuel and air is ignited beneath the piston and compressed air is pumped into a reservoir in response to the piston's upwards motion. The reservoir of compressed air is then used to assist in expelling contaminated gases to increase the pressure of the air and gas mixture, and to serve as an additional source of stored energy.

In the first alternate embodiment, concentrated solar energy is directed onto a liquid in the bottom of the cylinder to provide an expanding gas beneath the piston. As the piston moves upwards within the cylinder, compressed air is pumped into a reservoir, after which it is available to serve as a source of stored energy.
