Bladeless wind turbine...

Hi,

Just for fun I wrote the Canadian distributor of the Windside turbines. The smallest one weighs 38 kilograms and costs $6500.00. It produces between 6 and 9 amps maximum depending on how it is wired.

I think it is about 3 feet tall, plus any mast. They are intended for battery charging.

The proof of this is vaporware. :B

To my knowledge, VAWTs don't even come close to what a HAWT can produce come a steady wind. However, a VAWT seems to be better when the wind is variable (central TX wind can be calm one second, gusting the next, so it is a great area for solar, but not for wind generation with HAWTs.)

Now this gets me curious... I wish that the Windside folks had a RV-friendly turbine. A small one wouldn't be handing me 250 watts like a HAWT slapped on a tower, but it would bring in something, especially if the wind is variable.

Now that's what I need, some good vaporware.

Really? How many eagles have died from wind turbines?

It might be more interesting if they actually explain how this wondrous product produces electricity so amazingly. At no point do they explain how this fantastic product works.

If it were in the computer industry it would be called vaporware. :)

Both of the wind generators posted above have serious physical deficiencies because they will loose energy when their driven parts come back into the wind. It has been proven many times over that a conventional Horizontal Axis Wind Turbine will harvest more energy than a any other like a Vertical Axis Wind Turbine or any of the other designs.
ol.

beg to differ,

from Windside.com whos been around for 30 years and have these turbines installed in some of the worst weather condition of. the world

Measuring
Product testing

Mechanical durability and torques of the new wind turbine were tested with the WS-0,30 model in the Finnish Technical Research Centre in the year 1981.
In the year 1988 the same research centre tested the wind turbine again in its ship laboratory and a little later in its engine laboratory. Windside itself tested the turbine in Åland with an electric motor. At the same time, in 1989-91 the Finnish Army tested WS-4 turbine in the archipelago of Finland. The test lasted continuously 450 days. During this time the energy production was measured with the help of a computer, giving 8 values per second.

An example of computer measuring in the archipelago of Finland in 1989-1991

Generator production in Ah with different wind velocities in the Finnish coast, autumn 1989 - spring 1991. The measuring proves that Windside Wind Turbines produce energy at least 157 days more per year than the conventional horizontal propeller types.

Already in the tests made in 1981 it was discovered that the vanes of the Windside turbine do not freeze while rotating. A customer, who uses the WS-0,15 model continuously in Utsjoki, Lappland, made the same discovery in the winter 1993-94: the vanes do not gather snow or ice while rotating, even in conditions in which all the other turbines freeze.

Despite the excellent testing results, the strongest qualities of the turbine were discovered in the actual production usage. The strongest advantage of Windside lies in its ability to take advantage of even the lowest wind speeds.
The electricity production of Windside begins even with the wind speeds as low as 2-3 m/s, and the bigger the turbine is, the lower wind speed it requires to start. According to measured results, the 3 m/s winds blew during 100 days per year in inland areas.
The propeller models based on the traditional aeroplane engineering cannot take advantage of these light winds, usually their production begins at wind speeds of 4-5 m/s, from moving wind. The wind direction is not a significant factor for Windside, either, since the wind catches the spiral-shaped vanes always from the right angle. No automatic, easily broken turning mechanisms are needed.

The studies made in the archipelago show that The Windside Wind Turbine produces a minimum 30-50 % more electricity per year than other wind turbines with the same swept area. Windside’s efficiency is better, when the wind speed is under 5 m/s.

Furthermore, its vertical turbine is able to take advantage of all winds, while stormy winds and the changes in wind direction and turbulence significantly diminish the efficiency of the traditional models.

This article speaks to the advantage of the VAWT to harvest in low wind speed. There is no correlation as to a similar HAWT designed for low wind speed. Why? Because HAWT will harvest more as the wind speed increases and energy harvest is to the square of the speed. You can do the research yourself but the HAWT is the most efficient harvester of wind energy in all practicable terms. One advantage that a VAWT does have is that they are usually mounted close to the ground because of size. That allows for easier maintenance.

Oh, also, they look cooler.:B

I love these threads! Somehow it's evolved from wind turbines to cats in less than a dozen posts, good stuff!

These may or may not be as efficient as a Horizontal Axis Turbine, but they are much cooler looking.
Of course, that's only my opinion. :)
