Hello, ... This is my first post on this site. I originally started to design a HAWT but then I realized that it is not practical in the more urban area I live in. I researched and found then a Lenz VAWT is very good for starting in lower wind speeds...

I've been talking to d3lilley on private message about where to get aluminum for wings on a Lenz turbine. I get mine from a sheet metal shop. They sell by the square inch of ft. Does anyone else have suggestions where he can get something for the wi...

Hello Vawt folks, ... ... Well, here it is, my first attempt at a Helical Vawt using a 12 foot long Polycarbonate panel cut in two with my tin snips. ... Swept area is about 18 Sq. feet. ... ... I am very excited about this one because it is...
I built my own alternator. As you know this means winding coils and gluing magnets. I doubt I will ever do it again. ... ... We all have the ability to build our own alternators but do we really need to. There is no cost savings in building a "...

Hello Guys, I've been reading tones of this from your sites and seen every one's opinions about the different designs, projects and their efficiency. Today I've desired to post my first project Idea witch I would like to add i...
Does anyone have a reasonable reference which can explain the pros and cons of various NACA airfoil profiles??? ... ... I have been playing around with building a small VAWT for a while and so far everything I'm doing is based on a NACA63-4-021. I...

... Well, then, here are the results of trying to heat-form the 0.065" ABS sheet into the leading edge of a c-rotor. As I learned earlier with forming the "c" part...
I've written a spread sheet for Microsoft Excel that will do a crude computation on well an airfoil will do in a VAWT given a wind speed and blade speed. It tells you the total power for one blade and shows a chart of power vs rotational position. ...
hello friends ... Today i build a 50cm Lenz 2 Turbine for comparison with a 50cm C-rotor on my teststand. ... The funny thing is that a friend of mine was helping me to build the turbine, and his last name is Lenz too, no joke. :) ... ... For now i ...
I'm pretty good at electronics and computers, but when it comes to making mechanical things, especially out of heavy metal I have no experience. Up to now, all my turbines have been small and based on 1/2" threaded rod that I got from Home Dep...

Hello, just joined friends. Hope I ask this question in the right place. ... ... I am currently making an 18sq.ft. Helical type VAWT. ... I was wondering if the twist angle of each blade HAS to bend around 180degrees? ... ... If I can't twist e...
I started working on my OpenFOAM help site. My intent was to set up step by step instructions to lead someone through setting up the software. I even cleared a disk and reloaded everything from scratch so I could do that steps as I wrote it to make...
This turbine is based on the Jellyfish that was the result of my genetic algorithms. I removed the tail and only used the round head and unusual angle. In simulation this is nearly as good as a Lenz2. But who knows if we can trust simulation? ......
These youtube videos show some of the designs that have come out of a German discussion board something like ours. The posters name is VAWT1. The vawt design is something like a Lenz2 but the fin is curved to the radius of rotation, and meets the ...
Can anyone point me to a profile of the NACA 0018 airfoil? I have several documents that have some airfoils, but have had no luck finding this one, as well as others commonly mentions in these pages. ... ... Thanks, ... ... Turtle...
