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
Solar food dehydrator
Drying food in the sun is a method of preserving food known for thousands of years. To this day in many, especially the poor and to the equator the closer countries, dried foods in direct Sunlight. The most commonly
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.
Terracotta (ceramic) cooler
Evaporative cooling of water from the surface of the ceramic material known as terracotta (terracotta). Water absorption terracotta keeps the material constantly moist. This property is used to cool the rooms.
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
Mashrabyia – cooling niche
Mashrabiya was, and still is, a popular construction element of the urban multi-storey houses in the Middle and the Middle east, or North Africa. It's about the niche in the first and higher floor
