, and wind could really use any house owner himself as an energy source. There are already many designs that you could do this and that are sold just for the purpose. However, their efficiencies are often so small that the costs of proportion to any benefit more. Large wind turbines (WT ) run only twenty-five percent of their time to make loud noises, throw shadows, because they have to respect different from one municipality to large distances from settlements, and from time to time also a bird flying against it. All this would be avoided, when constructing a system that is mounted on a house is, because it would then be finally in the middle of a residential area. Therefore, such small plants even less effective than large designs. Nevertheless, there are a few good solutions. But the most promising at the time, actually is intended for large wind turbines developed at the Technical University of Delft and they could already be used in, I lack the initiative to do that.
The method the Technical University Delft is being tested, rather than traditional wind turbines used a stunt kite that is always directed into the wind. There he is pushed away by the wind and transfers the force of the wind on the winds, of which he is held. Thus, the Technical University of Delft already receive enough energy from the wind, ten houses to be supplied with energy. This is no more than a dragon out of ten square meters at a height required of eight hundred meters. This can be done not as a private household, since we may use the air space only up to a height of hundred meters free. But a household is more likely a single household with energy supply and not ten. In addition it can still use other energy sources. The method with the dragon to seventy percent of the time deliver energy. The technique could therefore already provide many households with a large portion of their energy requirements from a freely available source!
by the same inventor also originated the idea, the propellers could be used to generate electrical energy from wind. This is a ship equipped with both an electric motor as well as sailing. As long as enough wind blows, the ship is sailed. At the same time while the ship is moved, the propeller rotated by the water resistance and the electric motor acts as a generator with the ship's batteries be charged. Blowing wind is not enough or you drive into a port in which it is not allowed to sail (which are the most, because in reality no one is interested in saving energy or fossil fuels), then pushes it to the vessel, the electric motor. An electric motor is of course not the most brilliant of all the drives, but you can use the least as a generator. If you do that on a sailing ship, you have the principle that only copies of existing wind turbines. Still, I know of no ship that uses the well-known principle already. use
