Airborne wind generator

a brilliant idea i saw in Discovery Channel. it's made out of plastic with helium filled in. doesn't consume lot of space as the wind mills does. it's not as dangerous as the wind mills does and the best is, doesn't cost as much as wind mills does. it flies 300m above to get constant amount of wind to rotate the balloon. this is because at that height, the wind goes on continuously as how you see the clouds moves. but if you're thinking of residential generator, there are smaller scale of these. so you wont have to pay more to get energy as what our main suppliers are giving whom monopolize the country's source. e.g; TNB. well, it's a new invention, but it is a brilliant one. a very good idea of saving cost. and it also an environmental friendly project.

When the generator is on the ground, then the tethered aircraft need not carry the generator mass or have a conductive tether. When the generator is aloft, then a conductive tether would be used to transmit energy to the ground or used aloft or beamed to receivers using microwave or laser. Airborned turbine systems would have the advantage of tapping an almost constant wind, without requirements for slip rings or yaw mechanism, and without the expense of tower construction. Kites and 'helicopters' come down when there is insufficient wind; kytoons and blimps resolve the matter. Also, bad weather such as lightning or thunderstorms, could temporarily suspend use of the machines, probably requiring them to be brought back down to the ground and covered. Some schemes require a long power cable and, if the turbine is high enough, an aircraft exclusion zone. When the generator is ground-based, the tether need not be conductive.
