You assume they work.

History tells us that they are unlikely to do so. Best we wait for data from a reliable source.

There are HAWTs in use on thousands of off-grid ranches and homes right now. They do work.

Several VAWTs have been marketed. They’ve failed.

Or you could put up HAWTs which have been shown to work and produce power.

Andre and Aj – you can make those claims but if you look around in the real world you will find almost no VAWTs producing usable power.

VAWTs were given an honest test a couple of decades ago and they simply fell by the wayside. Many artistic blade designs have been presented over the years but none have produced an impressive power output.

Do you see a power production curve for this wind-flapper? Or just some wordage about dimples and stuff?

I have a pat pending V.A.W.T. design that is capable of creating useable energy in less than three mph.A PRTO THAT HAS A SWEPT AREA OF 48 sq ft has generated 3500 watts in 24 mph over 20 hp in 35 mph.I need serious partner.e-mail lyle.upchurch@gmail.com

Dear Mario, the concept of power generation in vertical windmill is different from horizontal and hence it can use winds from any direction and provide cut in wind speeds lower then horizontal windmills hence are quite effective in lower wind speeds and offer cheaper alternative in less than KW and Watts scale for off grid power generation coupled with solar PV.

Dear Barbara, but vertical windmills are primarily being targeted below MW scale since they provide cheap power in off grid mode along with solar PV panels using thin film. Hence these are compting with big wind farms but are good for off grid ranches and homes and rural electrification purposes.

OK, Who out there wants to develop a turn-key 5 Megawatt facility with this new Vertical-Axis Wind Turbine? Experimental as it is.
Please only serious inquiries.

Dear Reader:
I have been reading about wind turbines to explore what possibilities are out there in the world. Since your web page allows comments, please allow me to make some comments. Nothing is toward you or your company but rather to the wind turbine industry.
The very first thing that SMAKED ME in the face is cost. Yes I know you need to be paid back for your R & D cost. Consider which would be better for anybody in the business of selling pencils. There are 2 possible ways to become a millionaire selling pencils. You can sell one pencil for one million dollar or sell one million pencils for one dollar each. Which would be more likely to happen to become a millionaire?
Next item. Many of you have designed systems for many different conditions. However, I haven’t found anything (other than battery backups) to make it easy to switch between wind generation and returning back into the grid when there is lack of wind. Most of us do not wish to have anything to do with batteries and all that is involved with them.
I think there are many people in this world such as I. I have a portable generator for backup power. In conjunction with this generator I use a “power transfer switch” such as: http://www.amazon.com/dp/B000HRYG2Y/ref=asc_df_B000HRYG2Y1317207?tag=thefind0012289-20&creative=395261&creativeASIN=B000HRYG2Y&linkCode=asn for a very easily switchable system between generator and the grid in either direction.
In my humble opinion a wind turbine manufacturer that would utilize a similarly ease of use switching between the power grid and the home/business at a reasonable price will take over the market.
Sincerely
Laszlo Kovacs

Tough crowd. You are all assuming that these will be deployed in areas that already have access to power. We could use these micro turbines in a rural telelcommunications environment powering remote Optical Network Terminals that require 24×7/365 power in locations with seasonal (or no) power. Solar has been considered, but a micro wind option would be great to have.
