Odrey, your prototype went on a form like this?

It can be funny. Good luck.

The flying wind turbine from altaerosenergies

http://www.altaerosenergies.com

Altaeros Energies gives birth to a flying wind turbine

Usine Nouvelle on June 11, 2012

Altaeros Energies, a young company, has designed the prototype of an eleven-meter-wide wind turbine equipped with a balloon inflated with helium, the Airborne Wind Turbine.

The objective of such an innovation is to reduce the cost of wind energy by 65%, in particular by benefiting from higher and regular winds at altitude. The group also benefits from lower installation times, from a few weeks to a few days.

The concept was tested last March.



If someone finds the info on the power of this wind turbine it would be great.

But given the diameter of the blades, it doesn't have to be much. Within 10-20 kW?

Cool!
When is a model capturing the power of jetstreams?

Rein notes that the company uses an "off-the-shelf" 2.5-kilowatt, 3.7-meter, 3-blade wind turbine merged with helium inflatables that have lifted radar systems for decades. The unit is rated to go to about 1,000 feet in the boundary layer. The tallest terrestrial wind turbine is 350 feet high.

Interesting this altaeros energies prototype which looks a lot like this diagram from 3 years ago:

For power yes even less than 20 kW ...

ps: lessdewatt, put your photos on our image host please ... thank you ... for the following!

2,5kW, it's not heavy, but it's already a beginning.
The problem resides in the fact of raising a generator in altitude, if one wants a lot of energy it will be necessary to have recourse to gigantism.

if there is wind a simple kite without helium or hydrogen is enough to go up in the air

if there's no wind, there's no need to keep the thing up

conclusion the helium balloon is never used for nothing

a helium balloon is very expensive: all materials are porous and helium is a very expensive gas

2,5 kw? I see it coming that the loss of helium is likely to cost more than the value of the electricity produced

I rather see a kite wind turbine which rests on a mast when the wind is too weak, and goes up when the wind is enough to make it fly

The concept already exists, the problem is that the wind fluctuations do not allow the device to stabilize long enough to make it economically efficient, not to mention the risk of crash ...
With a balloon, this is more practical, but remains more expensive, nothing prevents replacing helium by hydrogen - cheaper- since there is no traveler to transport ... but the risk of crash is always to be feared.
