Big kite type wind generators that you mount on the roof of your house - when there is sufficient wind they are lifted high into the sky. Contained in these kites are generators (maybee as an integral part of the lifting suface - like a gyro copter).
Generated electricity returns to the ground via
a conductive cable.

Jetstream wind farm

I was just getting quite excited by the thought of posting "Jetstream wind farm" - exploiting the high speed, constant winds of the jetstream, but a quick Google search revealed it has already been thought of... [hippo, Nov 18 2004]

Wind energy's significantly greater just a few metres above the ground (I posted a link on the last wind-power idea, I forget where) so this could be a sensible way of using that extra power. |
|
| |
With flying windmills you could play flying miniature golf. |
|

Get rid of the whole kite thing, and just have it as a gyrocopter, that way you can give people rides as well as generate electricity. |
|
| |
Better using the gyrocopter for lift only, and having another blade driven generator for the electricity. The wind vector is usually parallel to the ground so a vertical blade surface would be preferable The gyro blades also have to support the mechanism, so to provide lift and generation would be inefficient. Getting planning permission for a helideck on the roof might be tricky though :-) |

Thing is, we all can clearly see what the original poster *meant* to say, even if they couldn't. |

sad thing is, some of those are accepted acronyms... |

Baked. Oh! first time I got to say that. see link |

Even better, you can give your enemies a ride into power lines. There's an evil application for every good-hearted application. |

Wasn't this in popular mechanics about four or five months ago. Australia was building kites with wind generators attached to them to harnas the power of the jet stream. |

<personal misunderstanding> Flying Wind Generator = helicopter? </personal misunderstanding> |

Tethered helium/hot air ballons? |

We kind of half-seriously looked at this for masts for our community wireless project |

This is meant to fly at 15 to 35 000 feet where wind supply
is consistant and they've calculated it can easily beat coal
(current cheapest energy supplier) and also it can
generate hydrogen through electrolysis. Hydrogen has
been sited by GeneralMotors as a alternative source for
driving cars! And they would generate it by burning oil or
coal. The by products of hydro-cars is water! W.A.T.E.R.
So consider this half bake as frozen and ready for final
baking to happen at home. Because we should adopt this
to solve all our problems. www.skywindpower.com/ |

I remeber reading this in popular mechanics, it's actually
used in like austrailia, that's a great idea. |
|
| |
Cool idea, but dynamos to create electricity tend to be kinda heavy with all that copper winding and magnets though, might take a pretty massive kite. I've gotta go check out that link now see how the Ausies did it. |

According to [bing]'s link, thousands of the devices would fly 4.5km in the air. That means that to eliminate the chances of air collision, aircraft (including other flying generators) must stay further than 4.5km away. Assuming each full-sized unit would have a peak capacity of half a kW and operated at 85% load factor (Prof Mills: "flies six days out of seven") and occupied a hexagonal exclusion zone of 4.5km side-side, then the energy density of the power station = 500W / 4.5km 3×sqrt(3)/2 = only 42 Watts per square km!! |
|
| |
Also, the wires represent a horrendous hazzard to aviation. Where I fly ultralights, aircraft have been hit by kite strings in the approach path. Kite strings are completely invisible till they hit. As the plane flies along the string is dragged by the wing, slipping past so fast that they almost cut through the spar. |
|
| |
Instead of the thin, cheap natural fibre they use in those parts (not fishing line, thank God!) you propose to use a substantial wire capable of transmitting electricity. |
|
| |
With this in mind, I'm rethinking the validity of my own (near identical) idea. |
