Watter Buddy

This little machine generates DC power from a source such as a stream running down a hillside. Water is channelled into a pipeline with enough drop (head) to build up sufficient pressure. It can also be used with water systems that are under pressure like the water in city supplies. The water passes through a small nozzle where it gives up pressure for velocity. The water then passes through the turbine runner which converts the energy in the water into shaft power and spins the generator. This electric power is first alternating current (AC) that is converted into direct current (DC) with a device called a rectifier. The power then goes to the output terminals (binding posts) where it is available to charge batteries or use directly with suitable appliances.

Brass nozzles are supplied with the machine in sizes from 3-7 mm. A range of sizes are provided so that you can match the nozzle to the flow rate (l/s or gpm) of your source. Higher head (pressure) sources can use smaller nozzles and pass the same flow as larger nozzles at a lower head. The wheel has a pitch diameter of 2” or 50mm. The brass fitting on the machine is designed so the nozzles are on the inside and the inlet pipe connection on the outside. This fitting has ½” pipe threads on the outer end for use with threaded type plumbing, in addition a plastic adapter is supplied that fits ¾” plastic pipe.
