I've got a sixty foot fall over a length of 1700 feet. My flow is about 20 gallons per minute in the dryest weather. Thats alot of pipe. In my case, the water flow runs through a ravine and the pipes would necessarily have to run down through the ravine where they'd be subjected to those flash floods in summer storms and hurricanes. What is normally only 4 inches deep and ten feet wide can become five feet deep and sixty feet wide. whole trees can wash down the ravine.
Question, is that just the pelton wheel or does it include a brushless alternator/generator? and what is the max out put. most I've read about are limited to 1200 or 1500 watts. Now that is alot of energy. but a water heater in a four person household takes about 900 watts constantly to maintain hot water. One of my neighbors has wired his old house for 120v but isn't connected to the grid, he uses 12 volt light bulbs for now and has a combination of a solar unit and a small windmill to charge three marine batteries. He's only there on weekends, and it provides him with electric lights and he runs a 12 volt TV.
