Water turbines generate very reliable power with a very simple design. Some kind of "runner" or is attached to a propeller shaft that operates an alternator to generate power when water turns the runner. There are quite a few types of turbines, but they fall into three major styles: impulse turbines, reaction turbines and submersible propeller turbines. Each is ideally suited for a different type of water supply. No matter what source of running water you have on your property, if it supplies a year-round flow of water, there is most likely a water turbine well-suited to provide electricity for you.
Customising water output is also important during the use of the hydro-electric boat. Some ideas are
Water turbines come in a range of output voltages, to match the overall voltage of your electrical system. While 12 volt is common for small to mid-sized systems, large systems can be designed in 24 or 48 volt configurations. For marine use, most boats will have a 12 volt system.
For impulse-style turbine systems, power output can be increased in high-flow sites by using multiple nozzles on the runner enclosure and/or using a larger diameter runner. Many reaction style turbine models also come with the option for two or more runner diameters, with the larger option providing more power for higher flow sites.
In sites with sufficient water flow volume, multiple turbines of any style, or a mix of different styles in some cases, can be assembled into a single high-output system.
thats all I've researched
