Magnus wind turbine
A cursory look at the wind turbine using the Magnus effect (effect) you will be little doubt that it is possible to spin, and even generate energy. She has no profile leaves or blades
Wind turbine with deflector (rectifier)
The classic multi-directional resistance of the turbine have the wind, exposed to the driving area. That converts the energy of wind to rotational motion. But also they have a face that does nothing to capture wind energy and turbine brakes.
Water pump Ismail al-Jazari
Pump draws water from the bloodstream of a stream or river to the elevated places – for example, reservoir, or irrigation channel. It uses the kinetic energy of the flowing water, so their work doesn't need
Panemone wind turbine
Vertical axis wind turbine, an invention more than a millennium old, or also a patent from 1977 and one of the stepping stones for other modern turbine types.
Lenz wind turbine
The Lenz turbine belongs to the group of vertical omnidirectional turbines and its design strongly resembles a Darrieus wind turbine with a "hollowed out" wing interior. It is evident that the author tries to combine two basic principles, namely the resistive
Archimedes wind turbine
Resistance turbine with horizontally oriented axis of rotation. The fancy-looking wind turbine's name refers to the geometric constructions of the mathematician and physicist from Syracuse, Archimedes. The profiling is based on the shells of molluscs and snails.
Photovoltaic cell and panel
Direct conversion of solar energy into electrical energy. The amazing invention known throughout the world, which we find on the roof of the most modern buildings of the world, even in remote indigenous village in the middle of the jungle. How to in
Darrieus wind turbine
Buoyancy vertical omnidirectional turbine. Buoyancy means that revolves thanks to the difference in pressure between the two sides of the driving blades. Vertical indicates the deposit of its rotational axis perpendicular to the surface, what makes it even
Thermoelectric generator
The production of electricity by conversion of heat differences to electric current. The principle of Peltier cells, which are widely used for cooling, finds application as a thermoelectric generator. Just make different temperatures on the two surfaces
Sand energy storage
Sand is a suitable material for energy storage? When, after a sunny day we'll come to the beach at night and get our hands in the sand, will be tepid. In our country must do a children's sandbox
