Generating electricity from hydropower involves harnessing the kinetic energy contained in water that is being forced by gravity from a high place to a lower place. Humans have used hydropower for centuries and many of the micro hydro projects being installed today use the existing infrastructure of a Victorian mill, for example and adapt it for electricity production. This is common practice because building, new weirs and mill races is often too expensive to make micro hydro projects viable. Hydropower is a very constant, reliable and long-lasting technology (there are many hydro-electric turbines from the early 20th century that have been reconditioned and are in operation today). If you have a suitable body of water, you should consider hydro.
We are researching the micro hydro market and plan to bring products to Generator Your Own in the future.
