# free heater circuit by Rosemary Ainslie

Rosemary's original test circuit is shown in the article she tried to have published in a `refereed` scientific journal, but the submission was always rejected. In the last 5 months, I have had extensive email correspondence, and numerous telephone conversations with Rosemary, who lives in South Africa. After studying her work, I was absolutely thrilled with her discovery of the super-efficient heating effect. In mid-February of this year, I proposed to her an `idealized` schematic of her DC resonance circuit to produce the effects she had discovered.

OK, Here is an explanation of the schematic diagram above, for the creation of an Electric Heater with a COP>20. PS = the Power Supply. This is the Primary Supply of energy to the circuit. Any NEW ENERGY required to run the circuit must come from here. It can be a battery, or any source of DC current. RL = the heating element (load) that has the electrical characteristics of both resistance and inductance. Electrically, the component is operated as an INDUCTOR to be charged and discharged in sequence. C = a Capacitor of sufficient capacitance to act as a secondary power supply to power the circuit and to act as a reservoir to receive the energy returned by the inductive collapse of RL. D1 = a Diode to make sure that energy can only move in one direction, in this case, FROM the power supply TO the capacitor. This component prevents any of the energy returning from the inductive collapse from traveling all the way back to the primary power supply. So, in operation, this Diode will allow the Capacitor C to rise to a voltage that is higher than PS, but it will never allow C to drop to a voltage below PS. SHUNT1 = a low value, calibrated resistor used to measure the currents leaving the Power Supply PS. Current pulses measured here, times the voltage of PS, represent ALL of the energy the circuit is "dissipating". Q1 = a Power MOSFET, or any appropriate switching device to allow currents to magnetize the inductive load...
