[NA] Nasa Developing Flying Wind Turbines.

"At 2,000 feet (610 m), there is two to three times the wind velocity compared to ground level," Moore said. "The power goes up with the cube of that wind velocity, so it's eight to 27 times the power production just by getting 2,000 feet (610 m) up, and the wind velocity is more consistent."

Send turbines farther aloft, into the 150 mph (240 kph) jet stream at 30,000 feet (9,150 m), and "instead of 500 watts per meter (for ground-based wind turbines), you're talking about 20,000, 40,000 watts per square meter," Moore said. "That's very high energy density and potentially lower cost wind energy because of the 50-plus fold increase in energy density."
So this explains why I could never get my kites down as a kid

A wonderful step in the right direction, good job Nasa

I agree completely.

But are these as efficient as the ground based units?

They're much more efficient.

Heard of this before. Didn't think it was Nasa who thought of the idea though. Could've sworn it was some foreign dude...perhaps he's working with nasa now.

They weren't the first guys to think of it, but this is the first time they're being funded on it.

Ah...hem, Nasa, DON'T F*** WITH THE JETSTREAM!

im sure I remember seeing a program about this. it uses some kind of natural affect, i cant remember the name of it.

trouble is, how do you space them with the density you can attain on the ground without them becoming a tangled mess?

Very nice... I would only hope that if this lower cost, more efficient method of generating wind energy goes into popular use, the general public's electric costs will be lowered as well.

Well if 1 one of these turbines generates as much power as about 50 regular windmills, I don't think that'll be a concern. Space them apart by about a quarter mile and they should be fine.

Worry not-- we are fairly smart.
You could very easily use simple solenoid based connectors that were very light Al or carbonates to connect the individual turbines to create a honey-comb like section.

An acquaintance of mine was/is working on a modular honeycomb wind turbine system that is proving to be very effective
