Flying Wind Energy Conversion Apparatus

Wind energy conversion apparatus comprising a lighter than air structure which is rotated by the wind to drive an electric generator which is located within the structure, the structure being untethered and wherein its rotation absorbs substantially all of the force of the wind so that its position can be maintained in a desired position.

A structure where the free rotation of the blade can be slowed or stopped so that the wind or some of it passes though the blade and less or no wind energy is absorbed by the rotation of the blade and therefore makes contact with a structure behind the blade, exerting pressure on this part of the structure and causing anything attached to it to move.

A Wind energy conversion apparatus comprising a wind turbine supported by, or integral with, a lighter-than-air structure, the part of the turbine that rotates being rotated by the wind whilst at the same time absorbing substantially all of the force of the wind so that the position of the apparatus can be maintained.
