Archimede wind turbine

Mini wind Archimedes turbines.

You can add a Micro Brushless Motor to turn on a LED.
The mini generator can be found on Amazon or Aliexpress.

This is one of the mini wind turbines with the highest efficiency (about 30%).

The operation principle of the AWT is inspired by the so-called Archimedes’ screw and consists in the rotating structure of the spiral-type device. 

Unlike the Archimedes’ screw, which was designed to transport fluids and was driven by a crank mechanism, the AWT works on an inverse principle, where the gaseous medium flows around the spirally curved blades of the turbine and sets it in motion. 

The resulting kinetic and pressure energy is, similarly to conventional wind turbines, transformed into mechanical energy, which is subsequently transferred to an electric generator. 

Compared to conventional bladed lift-type wind turbines, such as horizontal axis wind turbine, the AWT is characterized by the fact that it uses not only buoyancy but also pressure force for rotation.
