Honeywell Wind Turbine WT6500, weight 462 lbs, max output 2.5 KW, $6399 at Nothern tools. At most, 4 moving parts. $13.85/lb,$2.55/w.

Toyota Yaris, hundreds of moving parts, some with really tight tolerances. Weight 2295 lbs, max output 77 KW (106HP). About $14000 (list). $6.10/lb, $0.19/w.

Produced on an assembly line the way an automobile is, the Honewell wind turbine could be produced for a whole lot less. Mechanically, it is a lot simpler. Electrically and electronically, no more complicated.

If the price were brought down to the sub $2000 range, I could afford to splurge on one. At $6995, it is an expensive toy, that would not pay itself back during it's lifetime. THe cost of small windpower for the home needs to come down drastically before the average homeowner will consider it. It's the supply and demand scenario determined by price point. At the current cost of any wind power, it is an expensive hobby, and nothing more. (With the exception of a few remote households, where power lines cannot be strung to. Living in those places is a hobby, or if you prefer, alternate lifestyle- not practical for everyone.) With mass production on a large scale, wind power could become a common household appliance.

For a quick comparison, 2 stainless steel 18 cu ft GE refigerators would weigh about the same as the Honeywell wind turbine- and run $1800 without being on sale. Again- a lot more moving parts. By any comparison, all small wind generators are grossly overpriced, by virtue of limited production runs.

We have a high efficiency, inexpensive, multifuel (ntl gas, methane, diesel, HHO, kerosense, alcohols,biofuels, algoil ...) turbine to replace reciprocals and inefficient / expensive turbines. RET (Working name) Apps include off-grid gensets 24x7 or complementary to Wind. RET CHP NG Gensets will steeply reduce the cost of power to $.05/kWh. Sannerwind@gmail.com

Yes. There is great scope for small wind turbines as decentralised energy for battery charging etc. But the cost has to come down so that these can be installed on a wider scale in developing countries. Mongolia had 1, 50,000 Wind chargers. In Bogotá, Colombia a lot of small windmills are produced by Centro las Gravitas. The author designed a Savonius Rotor with concentrator for battery charging. Being vertical axis which can be fabricated locally with local material, it can find wider use in areas which are inaccessible to grid. It costs one thirds of the commercial small wind turbines for battery charging (In South India).As it is vertical axis it intercepts wind from any direction. The concentrator increases the wind velocity and since velocity is having cubic relation ship with power, it operates in low to medium wind areas. The Unit is Mobile and can be mounted on rooftop and on hills.

Wind turbine WT 6500 is targeted Advertising and marketing GLOBAL DIMENSIONS OF FRAUD!
-Power curve is false
-Yearly production is overestimated 3-4 times (Hardly 200-300kWh/yr)
-It is small VT of 500 Watt range
-Weight is 3-4 x more than standard
-Concept is full of nonsenses

After years of work on finding alternative energy sources, we have built the engine (mechanism) that generates electricity using compressed air. It is our deep conviction that the engine (mechanism), in the near future will be the most simple and affordable source of energy, because during the work it "use" two components, stocks of which are virtually inexhaustible in nature - water and air. The word "use" is in quotes because the work of the engine is done in the process of expanding the air. It can be said that air was rented from atmosphere, used and released back into the atmosphere. At the same time without any mechanical, chemical or physical change. Recover of compressed air occurs during engine operation. It would be superfluous to note that the engine is clean and completely safe, because, during its work,there is not combustion process or harmful emissions into the atmosphere. Examination carried out in order to license a new engine (mechanism), showed that it is - actually has quite a novelty and a great future. Because of the lack of financial and logistical resources, we could not finish the program and build a prototype, and in practice demonstrate engine's abilities. This prompted us to look for partners or investors. We decided to offer interested companies or organizations, on the equity basis, to participate in the completion of the project. The results will be unimaginable. We invite you to take part for works of making a prototype, and then together enjoy the consequences of success. According to our calculations on the production (construction) prototype will take between $ 100 000 to 150 000. The Working Group ,consisted of several professionals of particular specialties, under favorable conditions, can do these devices in six months and immediately begin mass production.
