Wind can be the same as the rotating magnets are used for wind power generation, and with the speed of the speed change. Therefore, a small wind generators increase in wind speed can make a significant increase in the number of mechanical energy. High-altitude wind speed very quickly and can spread rapidly on a global scale, while more easily than the surface wind forecasts. These characteristics of high-altitude winds prompted inventors and scientists will eventually hopes at high altitudes, where the wind has always been very strong. In the 20th century, when the energy crisis of 70 years, all kinds of new energy concepts continue to emerge, engineers and inventors for a number of design patents to use high-altitude winds.
They put forward two main design framework for use ever since. The first is basically in the air to build power stations, wind power generation at high altitude, and then transported to the ground cable. The second is more like a kite, first mechanical energy delivery to the ground, and then from the generator to convert it to electricity. In theory, these two methods are feasible, but has never been implemented before the technical feasibility of two comprehensive and rigorous evaluation.
U.S. Department of Energy there was a high-altitude wind turbine generator projects, the scale is very small, the high-altitude wind characteristics of the first accurate data will come from this project, however, since the 20th century, 80 years of energy prices plummeted during the Reagan administration's Department of Energy officials will Norway funds for his use, eventually led to its die a natural death. Despite the increasing attention in recent years, the world's renewable energy development, the project does not re-start, it is not because it is bad, on the contrary, precisely because it is too new and rather remote from reality.
