Lenzova turbína patří do skupiny vertikálních všesměrových turbín a svojí konstrukcí silně připomíná darrieusovu větrnou turbínu s “vydlabaným” vnitřkem křídla. Je patrné, že autor zkouší spojit dva základní principy, totiž odporový Read more
Odporová turbína s horizontálně orientovanou osou rotace. Efektně vypadající větrná turbína se názvem odkazuje na geometrické konstrukce matematika a fyzika ze Syrakus, Archiméda. Profilací vychází z ulity měkkýšů a plžů, Read more
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 Read more
Temperatures are rising, and central Europe, including our country is slowly moving from a moderate podnebného zones to the subtropics. Ancient cooling and ventilation inventions that I still could only see in the south Read more
The name refers to the wind turbine rotating permanent magnet stored in a hollow cylinder filled with fluid, which in this way we are trying to warm up. The whole magic is on the eddy currents, also referred to as Foucaultův Read more
Wind turbines are frequently used to generate electrical energy. The following thermal-wind generator changes the energy of the wind to heat energy and heats up the heating water. This uses the principle of the so-called Joule apparatus originally Read more
A genius, a widespread turbine bearing the name of its inventor, can benefit the energy of the wind from the low speed and at the same time, it is structurally very simple and the final product from a variety of materials.
Spinning polamu, but surely! It is at the hobby shop is very popular thanks to the simple design, the use of commonly available materials, and last but not least, for your easy to understand the principle. Also leaves considerable space Read more
What questions to ask, if we want to successfully operate the wind turbines in the us in the Czech republic.
Let it go! A device for converting wind energy to kinetic energy. This is either used for cyclic movement as is the case with the pump on the water, the older the water mills, hammer mills... Current Read more
