Hello everybody
I may be a little heavy, but I still have trouble understanding the technologies used for these "kite wind turbines"!
Apart from the principle of the conventional wind turbine, namely a rotor with rotating blades, or the kite that makes convolutions in the sky, which movement can possibly generate a work of energy production on the ground (although the performance must not be terrible), I do not see what effective technologies are possible to produce power with a kite.
On one of the videos, however, we see a cable that passes through a pulley on the ground, but the pulley does not really turn.
The 2 arguments which appear admissible for these “kite wind turbines” are:
- the economy made by the absence of the mast, but there is the whole system of winch on the ground and the cabling of recovery of the current created in the air,
- the search for a stronger wind and more regular in height, but to hoist a windmill several hundred meters in the sky implies that it is smaller. So finally, we gain on the quality of the wind but we lose on the production capacity of the wind turbine.
Do you know of other current-generating technologies used with these wind turbines?
