Abstract: A thermoelectric battery is disclosed which uses pipes connected in series made from two different metallic materials. The pipes are connected in an alternating manner and exposed to sunlight to increase the temperature therein. Other parts of the pipes are connected to a cooler temperature such as water or the ground to produce a temperature differential suitable to produce a voltage potential. The thermoelectric battery is also used to supply power to a swinging pendulum in which two different ionic chemicals are mixed at a selected time to generate electrical power. The thermoelectric battery, connected through a pacemaker circuit, produces a magnetic field at predetermined periods equal to a multiple of the period of oscillation of the pendulum, the field acting to give the pendulum a push in order to keep the pendulum from stopping.
