Today I was walking home from work when I saw an old sailing mast that our hoarding neighbour wants to get rid of, and I had an idea. Why not build a wind turbine. The internet is going to show me how, but I thought I’d put my own process here in the hope that it might help someone else.
The best resource I found pretty quickly was this:
That seems like a good place to start, but first I have some questions. What is the difference between a horizontal and a vertical turbine, and which is better? The first page of this answers this question pretty categorically:
Vertical ones are less efficient. Easy. What next? How many blades should I have? Surely more is better right? Well no:
Ok cool. So I need 3 blades. Right lets go and find some scrap bits of drainpipe….
