Wind-power has rapidly evolved over the last decade to become a key part of the alternative energy mix with towering rows of turbines now dotting horizons all over the globe. One of the drawbacks to the conventional windmill approach is that they are still low to the ground, so why not go to where the winds are stronger and more consistent – up. Like the Magenn Air Rotor System, KiteGen technology is aiming to do just that. The system generates energy by guiding tethered kites over a predefined flight path in order to rotate a ground based turbine and, while only in the testing and planning phases, it looks to be a promising solution. The large wings (or kites) in the KiteGen system are driven by avionic sensors located in a dome base that also houses an electric generator. The control system is designed to automatically guide the kites in order to rotate the turbine and maximize torque. As altitude increases, average wind speeds increase as well. This is a factor that traditional wind turbines cannot compete against, since they are stationary and are generally only able to reach heights of 100m. via gizmag
