That those who have never practiced the art of the kite raise the finger! To the University of Delft, in the Netherlands, student and teaching true pros became. Notably to throw and to pilot several square metre devices. Because to the University of Delft, iron is hard believed as that the kite will be an answer to the energy crisis. An archetype capable of producing a ten kilowatt power was successfully tested. The University intends to speed things up.

The more they are high, the more there is wind. It is for this reason that the producers of wind establish more and more big windmills to draw more energy of the wind. The kite, it, can steal from several hundred metre in altitude, or even in kilometres, where the wind will go probably never. Pick up the energy of these winds of altitude, it is the insurance of a regular production, and more important than on the soil. Where from the idea, which develops in several universities or firms of the planet, to construct kites capable of producing electricity. Some people aim at an inflatable device which turns under the effect of the wind. To the University of Delft, it is the traction on the thread that is converted by a generator installed in the soil. (see the video published by Guardian)

As long as the device takes altitude, it exercises a traction and product of electricity. Once in his peak, he goes back down all alone, before going back up by producing electricity again. Wubbo Ockels, of the University of Delft, imagines "Laddermill", a cohort of kites taken up on a curl of thread which each their turn go up and go down, so as to assure a regular production of current. The kite tractor of freighters was known, undoubtedly this old invention (more than two thousand years) has future …
