Abstract
Abstract An impeller is positioned within the flow of a fluid to be used to irrigate an area. The impeller drives a generator, which operates to charge and sustain a storage battery. The battery powers a receiver having an identification code by which the receiver may be addressed to receive commands, such as, for example, to open or close a valve, thereby providing fluid to irrigate an area. By opening the valve, the fluid flow is increased, and more power is generated and stored in the battery. In this way, power is generated automatically for the receiver, which, in turn, controls the fluid flow for irrigation.
