DIY Hydro Power
It’s scenic, it’s rustic, it’s tranquil – and it’s clean, renewable energy. This DIY water wheel was created with many recycled materials and generates about half of the designer’s electrical needs – complementing the output of his solar panels at the New England home. Hydro energy is an old, but not forgotten, sustainable [...]
A Chinese farmer has made his own solar-powered water heater out of beer bottles and hosepipes.
“I invented this for my mother. I wanted her to shower comfortably,” says Ma Yanjun, of Qiqiao village, Shaanxi province.
Ma’s invention features 66 beer bottles attached to a board. The bottles are connected to each other so that water flows [...]
The Turgo turbine is an impulse type turbine; water does not change pressure as it moves through the turbine blades. The water’s potential energy is converted to kinetic energy with a nozzle. The high speed water jet is then directed on the turbine blades which deflect and reverse the flow. The resulting impulse spins the [...]
The Sun Flow solar system operates as a pre-heater. Its function is to
raise the temperature of the water going into the existing system.
Year-after-year your maintenance-free SunFlow system will go on
providing a substantial part of your hot water needs.
A. Cold water inlet: The cold water line which normally goes directly into
the existing water heater is diverted [...]
This cast epoxy impeller is designed to provide efficient performance on micro-hydro Pelton wheel water turbines. Power from water increases with head and increases with flow rate but is limited by pipe friction.
Maximum power for any pipe size occurs when the frictional losses in the pipe equals one third of the static head. Any increase [...]
Another form of ocean energy is called tidal energy. When tides comes into the shore, they can be trapped in reservoirs behind dams. Then when the tide drops, the water behind the dam can be let out just like in a regular hydroelectric power plant.Tidal energy has been used since about the 11th Century, [...]
Kinetic energy (movement) exists in the moving waves of the ocean. That energy can be used to power a turbine. In this simple example, to the right, the wave rises into a chamber. The rising water forces the air out of the chamber. The moving air spins a turbine which can turn a generator.
When [...]
Hydroelectric power as an alternative to carbon producing energy sources is once again becoming a popular idea in the United States. The existing dams and rivers producing hydroelectric power are once again being looked at as a viable source of power.
How Hydroelectric Power Works
The way hydroelectric power works is that water falls due to gravity [...]
