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. Four alternate embodiments are disclosed: the first injects and ignites fuel at both ends of the cylinder and has no compressed air reservoir, the second directs the heat of concentrated solar energy onto a liquid in the bottom of the cylinder to provide an expanding gas beneath the piston, the third burns hydrogen to create heat which vaporizes water to provide pressure for lifting the piston, after which the water vapor condenses, thus tending to leave a vacuum for assisting the piston downwards, and the fourth burns hydrogen at both ends of the cylinder.
