RE: New turbine design works in urban areas

The one in the photo is similar, but the one I saw on TV had verticle blades along the outside of the helix axis to give the turbine more tolerance to over wind situations. Still, a comparison between these two would be very interesting.

After taking a second look, I started thinking about the thermal tower they were proposing to use in Australia. If you added a thermal chimney to either turbine design, you could greatly increase the wind draw up through eigher device. With that approach, you would get both wind and solar energy from the same device.

I do like the progress designers are making on these wind turbines. I just hope they can come up with a cost effective and simple to use design. Around here, we have a lot of wind and I know that Chicago is called the Windy City, so I think a lot of people can see the potential.

Thanks

It would be interesting to see how this approach compares to the helix based wind turbine developed in Chicago. It was a much simpler design, bird safe and could run either verticle or horizontal with full over spin compensation.

Thanks,
