There are already two of these in action outside Sainsbury Supermaket in Greenwich (UK), no danger to birds what so-ever, if you saw them you would realise that. No idea how much power they make though, but they look far prettier than the ones they replaced (conventional 3 blade types)

Hello,
I am a retired Aero engineer with a great interest in wind power and the possibilities of Vertical axis turbines. However, my experience has been that they cant really compete with the present propeller turbines for the
large mega watt energy grids, for two basic reasons. The swept area of VAWTs is much less than the prop
jobs, plus when mounted at ground level, the important matter of wind speed is much lower, and fairly prone
to turbulence. I have tried to design an efficient VAWT but have failed to find an aerodynamic breakthrough
that works.
I cant believe the giant maglev turbine supposedly being built in China is for real ! Even if it only claimed to
be as efficient as one HAWT, it would be hard to believe. Maybe they have discovered a major breakthrough
in physics and aerodynamics that I\\\’m not aware of. Mag lev is nice as a bearing, but it doesnt repel the laws of
aerodynamics. Please advise me if this monster is really being built ! Thanks, Glen Bolton

Any one has an idea how if this could be done on a large scale, say for a township… A hybrid of wind and solar… any sites for further info ?

Your wind power device looks to be just what we would want, only a smaller version, and less costly. Please consider making versions that could be used on farms and residences in rural areas.

a 5kw wind generator can produce 13087kwh electricity annually, suppose your country electricity is $0.15/kwh, so electricity amount is $1963.05, our wind generator life is 20 years at least, so it can bring value $39270. How cost-efficient!!! Meanwhile, it takes good advantage of wind energy—–free resource, protect environment.

We are a team of architects and engineers putting together ideas for a riverfront redevelopment. As part of our marketing package, we are including sketches of people gathering places. One of our ideas to create a sort of interpretive center of alternative energy. As such, we would like to show wind turbines, solar collectors, etc. We like the aesthetic of your helix shaped product and would like to include a picture or two of it in our proposal. Is it OK to copy and paste the images above into our promotional literature?

Hope to hear from you soon…

hello above friend, I think for industrial purpose, large power output, ours is smaller, Our hummer wind generator from 350w to 10kw can load colour TV, refrigerator, water pumping, washing machine, street lamp, lake shipment, beacon, lighthouse. Consumer can be resident, culturist, sea user, ship user and etc.
You can load http://www.chinahummer.cn for a check, if you are interested, please send emai to hummer-612@hotmail.com.

hi,
the wind turbine of EON model looks cool and futurestic one . Being in India were enery through wind turbines are used for Industrial purpose in a successful way and market for residential flats and homes are to be the next vast development in the country. I am very much interested on wind turbines workouts and energy output capasity details. Awaiting for your valuable mail.
regard,

i am a manufacture of wind turbine from china, yes, we have some successful case mounting a wind turbine on roof, it is perfect. pls add skype name “qiao” for further talking.

Hey,

I live in a tower (14th floor quarter) in front of majestic powai lake at Mumbai,India. There are plenty of wind all around the roof. The roof is clean and there is no cell tower there. Can we install some VAWT on this roof top ?.To get some electricity for the lift lights ? My company will sponsor the project. Please let me know if you can provide me the design.

Reagrds.

Am I mistaken or does this windmill look a lot like the Turby? That has been tested since 2002. Do a Google on “Turby” and you’ll see what I mean.

As a creative artist I can see this means of power on mountain tops as works of art. By all means, why doesn’t the USA make the right steps now and apply this art to the areas with the most wind. We need to get our act into gear for our children’s future. Thank you for your time. Ken Stockton

I am exploring the idea of 1 or more turbines at a location in Pennsylvania, USA. Varying winds, and directions, with conditions greater than the surrounding area because of geologic features. Ideas welcomed, Thank you, Mike Ross

Vertical-axis wind turbine

This type of wind turbine is not widely used today. It is employed in areas where wind speeds and directions are gusty and variable. There are two major categories:
1.
The Darrieus turbine works on the lifting principle. It has two or three vertical blades which rotate into and out of the wind flow. This type of wind turbine provides ease of maintenance as the operating gears and controls are located close to the ground. However, it needs an external source to initiate the spin, e.g. an electric motor or some other type of vertical-axis rotor.
2.
The Savonius turbine works on the resistance principle. The rotor turns relatively slowly, but yields a high torque. This type can be used for pumping water, but is not effective in the generation of electricity, as rpms above 1000 are generally best for producing electricity and this type usually turns below 100 rpm

I just thought that this would be some helpful info.
Personally i love the Darrieus design but i am holding judgement on its feasibility in urban areas.

There is one Finnish company producing “wind turbins”. Their product have some similarities with this product.

Check out your self: http://www.windside.com/

Here’s some quotes from their pages:

“Windside Wind Turbines will produce at least 50 % more electricity in a year than traditional propeller models”

“Their design ensures a minimum requirement for maintenance.”

“Windside Wind Turbines are soundless. (0 db) They do not kill birds or people. For these reasons they are safe to use in population centres, public spaces, parks, wildlife parks and on buildigs.”
