A convection column is used to produce a draft to draw alternately hot and then cool air over temperature variable capacitors on which a charge is placed, the capacitors being grouped in sets, and alternate sets of capacitors are each repeatedly heated and then cooled in such a way that while one set is being heated the other set is being cooled and part of the total charge that is shared by the combined sets is thereby made to cycle back and forth between the sets and to flow through a rectifier and a useful electric work load which are in series with these sets with the effect that useful electric power is extracted by means of the electric load. In one embodiment the two sets of temperature variable capacitors each have different types of temperature coefficients with respect to their respective dielectric materials, one set of capacitors having positive temperature coefficient and the other negative and both sets are heated and cooled together with part of their shared charge moving from one set to another when both are heated and said charge moving back when both are cooled to produce a moving charge and a current flow for useful work in a series connected load.

An electric power generator comprising: capacitive charge cycling means in the form of two sets of temperature variable capacitors, a bridge rectifier and an electric load, said bridge rectifier comprising an array of four rectifier elements connected in a series and forming a closed loop in such a manner that two of the rectifier elements have cathodes connected together and the other two elements have anodes at a common connection point, the remaining two junctions of the four rectifier elements being formed by connections between an anode and a cathode, and said capacitor sets and the bridge rectifier being serially connected in such a way that each of the two rectifier element junctions connecting the cathode of one rectifier element with the anode of another is connected to a different capacitor set and each capacitor set is connected to the other, the electric load being connected across the rectifier junction connecting the cathodes of the two rectifier elements and the rectifier junction connecting the anodes of the other two rectifier elements, said capacitive charge cycling means thereby being capable of receiving and of having shared on the sets of capacitors an electric charge which can be placed on them and of having a portion of the charge move back and forth from one capacitor set to the other through the bridge rectifier and the load as the capacitance of the capacitors is made to change repeatedly by temperature variations of the capacitors, and a fluid heating means in the form of a heat exchanger capable of contacting fluid to be heated with a thermal energy source, and a fluid cooling means providing a source of cooling fluid and being in the form of ducting with cooling fins and located in a cool place, and a temperature alternation means in the form of a fluid impeller having valving and ducting, said impeller being capable of moving a column of fluid, and said valving and ducting being capable of providing alternating fluid flow communication first between the capacitors of the capacitive charge cycling means and the fluid heating means and then in an alternate time period between capacitors of the capacitive charge cycling means and the fluid cooling means to thereby alternately heat and then cool the capacitors by means of thermal contact with the capacitors by the heated fluid and then by the cooled fluid flowing respectively from the fluid heater and then from the fluid cooler to the capacitors.
