who frequents my blog know my passion for KiteGen, a high-altitude wind turbine that promises quite a lot.
KiteGen STEM: The first wind power plant with high altitude
Well, it seems that the promises are for tramitarsi in reality it is already in the final stages of construction and will begin in September monaggio on the site, the first central high altitude wind of the world (ie a structure that will produce and sell the energy produced industrially).
Stem KSU is called, has a capacity of 3 megawatts and is estimated to produce energy for at least 5000 hours per year .... at least double the production time of traditional wind towers. To give an idea generation should be sufficient for at least 1,000 families
EROEI
seems to boast a hero (ratio of energy produced and energy expended to build it) about 70, to give an idea of \u200b\u200bhow high we can say that this value is a value comparable to that of first oil well in history, when it was enough to make a hole in the ground and pick it up.
The current oil should have an EROEI of 10-12, I think the traditional wind is at a around 7-8, while the solar PV does not reach even 5.
Too good to be true? You might think it's one of the usual buffaloes, but to give us manforte these values \u200b\u200bare 2 prototypes have precedtuto: the mobilegen and KSU1, through which it was possible to do simulations and collect data that allowed the design of the STEM.
HOW DOES IT WORK?
KiteGen The STEM is the first step towards even greater power, those with a carousel configuration, of which the STEM is a piece in which a series of kites are a huge rotor rotate.
To the STEM work alone, but that it is still beautiful and still) has a little trick: the yo-yo
operation . In practice the kite
share rooms and halls while driving a generator located on the ground once it reaches the maximum height (850 mile) the kite is pulled into practice on the one hand, in this way loses its lift and descend quickly share (up to about 400) while consuming very little power. At this point the kite strings are rebalanced and regains its importance, coming up again and operating the generator.
All this could lead to the formation of real colonies of these generators, you can install as many side by side with a mesh spacing of 100 meters.
like a virus
For those struggling to realize the actual meaning of the data of STEM do a small simulation. The cost of
one of these devices (at present) is around € 3 million, with expected production is possible within two years to reinvest the proceeds from the exercise of power production and install more 2. After another 2 years without any problems and could not chase out any money, get 4, then 8 and so on.
But this is only an estimate very carefully ... investing the proceeds immediately when you reach the figure of the cost of a STEM, resulting in higher yields in terms of hours of 5000 theorized (and everything says that this is more than likely), reducing the cost of a single machine production etc. industrialization. you could get a settlement proliferate much faster.
With an initial investment more consistent (keep in mind that the gas power plant in Novi Ligure are allocated 800 million euro) you can imagine what kind of impact could be possible within the framework of the national electricity production.
