This project, designed to help contribute to the running of a 600litre Reef tank (Marine fish and corals), was started way back in March 2014, it is now November. Delays have been frequent and for many different reasons but the version you see above, I believe it's Version 15, has overcome most of the problems and difficulties encountered on the way.
It is appropriate to say that a VAWT is not as efficient as a HAWT, but living on a housing estate, surrounded by turbulent wind and neighbours, a VAWT was the best choice. The difficulties I have encountered have been partly caused by the limitations of a VAWT, but mainly design flaws resulting in misalignment and resistance issues. The version you see above is the first version following a radical rethink of the design and as can be seen from the images starts with a vertical pole connected directly to the F&P motor. The connection between the two elements ensures alignment and is resistance free. See later.
Step 1: The story so far.
The images above show the very latest version of the VAWT built to connect to a modified F&P direct drive motor. This project has been on going since Marchand shows some of the modifications and changes that I have made to achieve my objective of a "renewable energy system" producing free electricity, 12 months of the year. When I started the project I knew nothing about renewable energy so turned to the internet for information. One thing that became very obvious from the outset were the plethora of opinions and approaches that had already been tried. This Instructable sets out to explain how I decided to approach the subject and I make no claim that it is the best approach, but what I can assure you is, that it works! There can be little argument that using water is the ultimate approach, with Tidal power being the most under utilsed resource in this country. Also, in my opinion, to achieve some FREE electricity 12 months of the year requires a combination of approaches. Living miles from the sea and having no stream in my back garden, I turned to the resources that were available, sun and wind to create a Hybrid system. This Instructable shows some of the design changes and modifications that I went through over a number of months to achieve an optimised VAWT fitted to an F&P motor. Why a VAWT instead of the more efficient HAWT? Neighbours, I live on a housing Estate! As the "system" was to be a stand alone, to power one particular object, a 600 litre Reef tank, I also incorporated a single solar panel.
