Solarflower.org - vawt

Hey guys, I wonder what you all think of this? This is a diy vawt for the layman like me. I find it very interesting but wonder if it is sustainable. What I find attractive about this vawt is that someone like me who lacks engineering and electrical skills can build it. It is very simple if you know how to drill a hole and measure something. This may have already been discussed on this forum but I haven't found anything with all the info here. It is similar to the lenz2 turbine.

...It is similar to the lenz2 turbine...

It is almost an exact copy of the Lenz2 turbine.
It's a great introduction to DIY wind machines, and can be coupled to a generator to make useful amounts of electricity.

the only difficulty i see is in creating structural members from folded aluminum sheets .
you can do it, but you would need to be a sheet metal man and be skilled with a bending brake.
better to spring for a few pieces of aluminum  extrusion  or angle iron.
 
as well, rather than aluminum sheet, the teardrop shaped end pieces could be made of wood or plastic. something you can get a screw into rather than all those folded over tabs.
