Most of the common machines used in workshops, industry, and farms are driven by motors of only .5 - 5 horsepower. The Watermotor will produce this amount of power at an extremely low cost and with a minimum of ecological disruption.High energy efficiency means that the quantity of water necessary for operation and cost of installation is greatly reduced, while on the other hand the number of actual locations where waterpower on this scale is available increases exponentially. In effect, every small fast-flowing stream becomes an important local energy resource, perhaps in many cases the only practical one available. In the world's hilly and mountainous areas there are often few roads and even fewer electric power-lines. While frequently rich in small scale water-power resources, the people are poor.
The Watermotor is a practical means of utilizing one of the easiest to use and most efficient sources of natural energy.
