this guy should merg with the Konarka power plastic company. In most places, if you dont have wind you have sun! Just a question. does anyone know how much airflow is produced by a hot roof in a place like so Cal? That might be worth experementing with.

Saw this wind turbine design on a UK satellite TV program about green energy and was impressed enough to look for it on the WWW.
I understand that the designer was inspired by Richard Buckminster(Bucky)Fuller, and that the shape of the aerofoils is a double helix, like DNA. Apparently the turbine is ideally suited to mounting on Chicago’s buildings because it “doesn’t mind” turbulent, vari-directional winds. It looks to be a beautiful and simple design, but the price is ridiculous. What a brilliant idea to incorporate flexible solar panels. At the right price, this design could change The World!
… Congrats & Keep Going!!! – Neal Pearson.

Would be nice if there was a plans/schematic package available for the do-it-yourself, build your own consumer base?

I think that it would be more efficient and produce more power if you merge technologies… take the flexible solar panels that Dr. Alan Heeger (UC Santa Barbara) is working on and line the turbines with them. You would have two power producers in one covenant package. I think green power is great keep it up…

Shanghai Aeolus Wind Technology Co. Ltd. http://www.sawt.com.cn also sells a vertical 1 Kw wind turbine (P1000). Costs are
Mill System..$1800
Controller….$280
Inverter……$500
Total………$2580
Cost factor for ordering only one (instead of many) is 1.05x
Total cost for 1 system is 1.05 x $2580 = $2709
Postage from Shanghai to the US (180Kg)..= $300
Total for complete system plus postage= $3009

The P1000 is designed to work at only 5.5 meters above ground level. Short tower, easy installation and maintenence.

You’re right about the current pricing of the turbines. The company hopes to cut the unit price when they start mass producing the product and can attain some economies of scale. Look for them to start selling them in the fall.

I think the asking price is a too high for the Aeroturbine. Assuming that you could get 5 Kwh per day out of the 1Kw 510V model and assuming that the value of the Kwh is $0.12/Kwh, yearly income equivalent would be

365days/yr x 5Kwh/day x $0.12/Kwh = $219/year

Therefore payback time in years would be

$15,000/($219/yr) = 68.5 years

Even if you could get 10 kwh per day (which is doubtful because where are you going to have wind blowing at 30mph 10 hours/day), the payback would still be about 35 years. However, the equipment would probably breakdown long before then.

Companies such as Aerotechnical International have to come up with more sensible pricing or they will not get to first base in selling their product.
