Abstract

Describes a method for self sustained generation of renewable energy by use of a piezo electric crystal actuator. Piezo electric crystal generates rather minute amounts of energy when deformed by force. The usable energy obtained by such actuation varies based on crystal size, applied force, but for an average size and for moderate applied force, could be about 90 micro joules. In order to collect reasonable energy for practically viable application, tens of millions of such actuation needs to be performed each second on a continuous basis.

Safely assuming only about 60 micro-joules energy for power output calculations, about ten million actuation per second will produce 600 joules of energy per second. The actuator consumes power, and achieves selfsustenance when the electrical energy produced by the actuator exceeds its own consumption requirements. As per calculations shown in detail section, it exceeds this threshold comfortably at twenty million actuations per second. The actuator is theoretically shown to be capable of over hundred million actuations per second, making available about 5K watts of excess energy for export, For a ten-fold power output increase, it can be safely observed that the actuator drive input energy demand increase is limited to less than threefold. Unlike most other forms of energy generation, where input energy is the motive energy, and the maximum output cannot exceed input energy minus all losses, here the input energy serves to subject the crystals to the motive force, and therefore does not share the same input-output relationship, and therefore makes possible its self-sustenance, a concept considered impossible in reality. As this is against the present accepted norms of science, the model and calculations are published, for a broader expert review and assessment to identify its viability.
