I made these SolidWorks Renderings in Tribute to a Very Fascinating Design.
Gizmag.com Article : DARWIND5 Wind Turbine
The DARWIND5 is an interesting Vertical Axis Wind Turbine of which (I feel) will be popular with individuals living Off-the-Grid
Unlike other Vertical Axis Wind Turbines, the Harvistor – Darwind5 design allows it to function at heights much lower than current Wind Energy units.
In addition, the 2012 Gizmag article mentions, ‘It doesn’t need a brake because it self-regulates the top RPM – until now, unregulated top speeds have been a problem with VAWT design.’
In addition – Much to the approval of the Survivalist ‘Prepper’ crowd – As-well-as operating at lower heights, the custom mount options allow the Darwind5 to be lowered for Service & Storage in a hidden horizontal position until needed …this also means generating wind power without having a tall turbine unit giving away one’s location.
In all seriousness, I feel there will be a lot of interest in the Darwind5 in the near future. This is one ‘Green Technology’ design that will actually function in Urban as-well-as Remote locations — Great Design!! Well Done!!

NOTE: The ‘Survivalist’ and ‘Prepper’ comments are my own opinion, and in no way represent the thoughts or opinions of the Harvistor Darwind5 designers… but nevertheless, their design is brilliant and I enjoyed creating the Renderings!!
