Here's my 'Mk2' Vertical Axis Wind Turbine (VAWT). I've always liked the lines of these, but they really caught my attention a few weeks ago when I realised that I couldn't explain how they work.
I'm now a lot less confused about how a wing works (really good explanation here if you're interested: http://www.av8n.com/how/htm/airfoils.html), and I've learnt a few new tricks with the printer.
This is my second version and it can generate a much bigger turbine regardless of the printer that's used; it's a lot more efficient with filament too.

update: I've added a couple of different blades sizes to suit different build volumes. If you're after something different, have a play with the SCAD file or if that's not your thing, let me know and I can generate some.
update 2: Well it's been up for a while now and I've got a
