The present invention relates to a wind power plant, which is an un-tethered autonomous flying device. This device, according to need, temporarily stores the energy harnessed from the wind, and later on forwards it to a receiver ground-station for further arbitrary usage. Like sailing birds, the invention applies the wind-gradients and updrafts for energy-production by means of dynamic soaring, - instead of static wind. The energy is temporarily stored in the form of liquid air. The liquid-air containers are made of flexible, double-walled plastic foil, and can be forwarded to the ground station by means of remote controlled or GPS-Guided Parafoils. The containers are discharged and folded on the ground, preparing them for the next use. A large number of such devices can be stored on a flying unit. This way a lot of energy can be produced by every takeoff, since the flying unit does not need to take the energy-storing medium (air) with itself, and the payload is only slightly limited. The invention gets around the limitations of conventional windpower plants, as well as that of the high altitude types of devices, and allows as of yet unattainable possibilities in windpower utilisation. |
