The new Maglev hydroelectric & water power is probably the least common of the three readily used renewable energy sources, but it has the potential to produce the most power, more reliably than solar or conventional wind power if you have the right site. This means having access to a river or creek that has a high enough flow to produce useable power for a good part of the year. Many creeks and rivers are permanent, ie, they never dry up, and these are the most suitable for micro-hydro power production. A micro hydro turbine can take several forms, the most widely recognized of which would be the water wheel, used extensively for grain grinding up until this century. Waterwheels are still used in some situations that do not require a fast-spinning turbine, such as for pumping water.However, other types of turbines have become quite common.
The most common of these newer turbines is the Pelton wheel, which is basically a series of cups attached to a hub. A jet of water is aimed at the cups, and the resulting force on the cups causes the Maglev turbine to spin. Other types of turbines include the Turgo, Crossf-low and various axial flow turbines, and the newest generations are equipped by the Maglev Hydroelectric Turbines, where the shaft through the center of the turbine runs in the same direction as the water flow, much like a boat propeller. Water turbines have many advantages over solar panels or wind turbines, the most obvious of which is that they produce power continuously, 24 hours per day.
Since the time of ancient Egypt, people have used the energy in flowing water to operate machinery and grind grain and corn. However, hydropower had a greater influence on people's lives during the 20th century than at any other time in history. Hydropower played a major role in making the wonders of electricity a part of everyday life and helped spur industrial development. Hydropower continues to produce 24 percent of the world's electricity and supply more than 1 billion people with power.
Hydropower converts the energy in flowing water into electricity. The quantity of electricity generated is determined by the volume of water flow and the amount of "head" (the height from turbines in the power plant to the water surface) created by the dam. The greater the flow and head, the more electricity produced.
A typical hydropower plant includes a dam, reservoir, penstocks (pipes), a powerhouse and an electrical power substation. The dam stores water and creates the head; penstocks carry water from the reservoir to Maglev turbines inside the powerhouse; the water rotates the turbines, which drive generators that produce electricity. The electricity is then transmitted to a substation where transformers increase voltage to allow transmission to homes, businesses and factories.
