my pre-commentator is right, you'll need way more cross section to produce adequate power. That little sucker might produce 10 watts at best ... an average usage of 10000kw/h per year can never be fullfilled by that one, not by five and not by ten either ...

It slices, it dices ... but wait! There's more! with this tiny attachment...his invention also claims that it will make hot water for you by feeding water through the horizontal axis of the windmill.

I'm not sure this inventor even has a plant building these, much less exporting them to the US. Just because he's applied for a patent does not mean the invention works.To build one yourself, you should be able to follow his patent application. A good patent should be able to teach his invention to others skilled in the craft of building one.Google for his WIPO Patent Application WO/2008/067593 or follow this link:tinyurl . com / 694jf6 after removing all the spaces.

I'm not so quick to buy his numbers. An average household as a rule of thumb uses about 9000 kWh a year, or about 1 kW every hour. The news reporter says 5 of these will supply that. I am not so quick to buy those numbers given the small cross section of his windmill and the fact it is fixed horizontally to work with one or two major wind directions. Someone may have forgotten the capacity factor in their calculation.And yes, I see no means of collecting it.

Fantastic! How can I buy or build one?

Notice this is a Patent Application and that it has no patent been granted yet. The queue is several years long. The spec does not really explain why the airfoil is novel over previous inventions. My guess is that the Patent examiner may determine that there is nothing novel.

Google for "WIPO Patent Application WO/2008/067593"The base claim is a novel airfoil. The rest is a horizontal Gyromill."1. A wind turbine apparatus characterised by a plurality of elongated turbine blades rotatably mounted about an elongated axis, each turbine blade having an aerofoil shaped profile with a continuously curved outer foil surface and a cupped or cutaway portion on an inner foil surface."

Looks great, but I did not see any load on it such as an alternator or generator or Gears required. What is the amount of power you expect for a 36 inch diameter drum 4 or 5 feet long? Is there any stats or power curves availible? You should post them.

"Things I can think of that can be patented are improvements of efficiency such as airfoil enhancements, and bearings at each side and maybe methods for attaching it."Well that's true. However, that would have to be a bearing or wing patent not a wind turbine patent. This gyromill still just uses wing lift exactly like a Darrieus Turbine. Putting on it's side is merely a new application not a new invention.
