Abstract: An anti-abuse circuit and method is described for shutting down a load wherein the load is connected to a controller having a predetermined range and demanding operation of the load through a relay until the predetermined temperature range is achieved. The anti-abuse circuit is positioned between the controller and the load. The anti-abuse circuit controls the relay when a demand signal is present indicating the operation of the load. The anti-abuse circuit energizing the relay during the predetermined time period and receipt of the regulated demand signal. The anti-abuse circuit de-energizing the relay when either the predetermined time period expires or the regulated demand signal stops.

Abstract: A method and apparatus for generating electricity which capitalizes on the energy which is released by steam through sudden transition to a liquid state. Electric current is generated by piezoelectric elements which are attached to the walls of a vessel equipped with an outlet port and two inlet ports. Cold water enters the vessel at one of the inlet ports. Steam is introduced to the vessel at the other inlet port. The sudden change in phase from the vapor to the liquid state caused by the encounter of the steam with the interior of the vessel produces shock waves which mechanically charge the piezoelectric elements to produce an electric current.
