Wind-powered heating eddy current
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 stream.
Slipstream is the electric current changing magnetic flux in the conductor. By passing the current through a conductor are formed of heat loss. These losses are commonly understood as undesirable loss on the lead and is trying to give them every possible way to prevent it. The following devices on the contrary, attempting these heat losses utilize and heat them of the heating medium.
As in the case of the Heat generator driven by a wind turbine on the principle of Joule machine see article: heat generator driven by a wind turbine... , is behind the discovery of the relation between electrical energy and heat responsible the English physicist James Prescott Joule. Recognizing that the amount of heat developed per second in a conductor, through which the electric current is directly proportional to the square of the current and the electrical resistance of a conductor.
Description of the device
This heat generator not coincidentally resembles an electric generator, but instead of generating electricity, focuses on the use of heat loss. By connecting the axis of the generator for a wind turbine device changing the wind energy to the electromagnetic and the heated fluid.

A cylindrical ring with a hollow inside is made of an electrically conductive metal material. In his the inside of the circulating heating water. Inside the cylindrical ring is axially positioned permanent magnet, in the case of the simplest design.
Since the thermal performance of the device depends directly on the frequency, therefore, changes the orientation of the magnet is the north-south-north-south..., it is advantageous to use a large amount of magnets placed on the outer side of the rotating interior. From this it follows that the larger diameter of the device can be placed on the axis of a higher number of magnets and so reduce the required rotational speed of the center. It simplifies the use of wind turbines without the need for převodování at a higher speed of rotation. This extends the number of usable wind turbines on nízkootáčkové.
Today it is possible to fabricate devices from neodymových magnets with a high retaining force. It brings with it substantial reduction device. A wide range of shapes and sizes neodymových magnets then expands the space for so a design solution.
The more accurate will be the production of the individual components, this will reduce the gap between the permanent magnets and a ring and zvroste equipment effectiveness. Which, of course, puts high demands on processing.
