A water wheel is a machine for converting the kinetic energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a large wheel (usually constructed from wood or metal), with numerous blades or buckets attached to the outer rim forming the drive mechanism. Water wheels were still in commercial ...
A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes.

Water wheel : advanced hydraulic water wheels and hydraulic wheel-part reaction turbine can have hydraulic efficiencies of 67% and 85% respectively. Overshot water wheel maximum efficiency (hydraulic efficiency) is 85%. [12] [13] Undershot water wheels can operate with very low head, but also have efficiencies below 30%. [14]
The impulse energy of the water jet exerts torque on the bucket-and-wheel system, spinning the wheel; the water jet does a "u-turn" and exits at the outer sides of the bucket, decelerated to a low velocity. In the process, the water jet's momentum is transferred to the wheel and hence to a turbine. Thus, "impulse" energy does work on the turbine.
Air–water gravity generator – Another invention from Rick Dickson, believed to be the hydro plant of the future. Pressured water is let into the Air – Water- Gravity generator which generates power by entering a vacuum chamber which then forces a piston to climb a stator. Electricity is generated at that point.
State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.

Water wheel: Water wheels can be used at low heads (1–5 metres) and medium flows (0.3–1.5 m 3 /s) and are considered safe for aquatic life. Gravitation water vortex power plant : This type of hydro power plant use the power of a gravitation water vortex, which only exists at low head.
