Check out all the negativity by what we can only assume are CEOs of their own wind turbine companies, currently marketing their myriad of products after years of research, trial-and-error, testing, revision, upgrading, etc., etc.

The video clearly demonstrates numerous similarities to various forerunner wind designs. The video also demonstrates major inefficiencies of the design. It seems clear to me that it was not designed by an engineer with aerodynamics knowledge. The ‘racket’ office will sell patents to anybody. There’s nobody home. They are asleep at the wheel. There are thousands of patents on the ball point pen alone.

I am all about ‘practical’ innovations and from what is demonstrated here, this isn’t one of them. (sorry to say) Keep working on it, you’ll get it sorted out. It is simply too inefficient (comparatively) in it’s current form.

I am in the alternative energy field and I like philosophy of close-to-user-site generation and specifically, the looks of this design. The bottom line:

If Toby listened to all the nay-sayers out there, he would never have invented anything. My hat’s off to him and all the inventors and entrerpreneurs trying to make the world less dependent on fossil and foreign energy sources.

can you put this on homes and what is the cost?

Attempt at selling snake oil usually involved giving little technical information but publishing excessive “great results”, especially on public media. Last I heard such claims are people trying to sell perpetual energy from generators running on water.

This is great.So many people are trying to compare these with hawts but it is obvious that hawts are not viable in urban locations. I like that this company is proposing to make them at a reasonable cost. So many wind companies are charging ridiculous amounts for their products which is helping to put people off. The materials are not expensive. To the people who consistently use the argument that they don’t produce much electricity , all you need to do is look at the cost of one and imagine having four dotted around your house or garden then you could realistically start to think about having a considerable reduction in bills within a year- it’s free after that and will last as long as the product does. The biggest immediate consideration is that I can put these on my hosue or around my property with very little fuss in terms of legality and planning permission. The are not dangerous and don’t make any noise. How many houses have four corners ? Imagine one on each corner.The other one of these that I am fascinated by is the HelixWind , it’s beautiful but those guys are charging enormous amounts for theirs , they are truly not going to change the world by having such a disproportionate cost. I am interested in making vawts even cheaper so much so that it would cheaper in one year to buy a couple than pay the equivalant electricity bill. The energy companies would then be seriously forced to rethink policy.

These vertical designs are not competitive in performance with the more efficient three bladed horizontal axis wind turbines. If you looked at the starting wind speed, they create too much drag to perform well in low wind. Well, low wind is what most people have. Pound for pound, dollar for dollar, and in terms of swept area or footprint, the vertical wind turbines cannot compete favorably against a real, professional wind turbine. Their site has a video of them running without a generator? Like a pinwheel blowing uselessly in the wind. The best rooftop wind turbines are like the ones that WindEnergy7.com has. These are miniature home sized models that are effective like the large Utility Scale wind turbines.

We are interested in your VAWT.

Can we have performencs details ? And would you consider trading with us in the UK ?

Kasia, the product featured by Mariah Power is neither a spiral as you claim, nor a helical turbine as in the Kincaid design. And if by “perfected” you mean they designed a wind mill capable of chopping to pieces any birds that may fly too near it, then “yeah, they did a great job”.

Whats the latest news on the availability of the turbine?
