Thanks to John Furze in Denmark I found this lovely manual for building small wind turbines “Energia Eolica” – Juan Ignacio and Sebastian Urquia Lus, published in 1982.
You can download it here
Unfortunately I don’t know Spanish so I can only skim through looking at the pictures but some of them are truly lovely, for example this one:
If anyone can lay hands on any of my old publications from the 1980s I’d be very grateful for scans. There were some nice cartoons by Cathy Dagg in some of them.
Efficient wind turbine alternators connected directly to batteries do not have the right speed range to make the best use of the blades on this blog…
Hi Hugh!
I’m planning to bluid a DIY windtourbine for our house in Conil (SPAIN), a very windy area. We already have mains supply, but prefer not to depend too much on this and catch the basic needs from renewable energy. We are now measuring the frecuency and directions, and expect to build first a small windmill from scrap and bycicle parts, and then another bigger one following your model.
I have already this manual and it would be nice if I could translate it into English! I will try! Drawings are very good, and I really enjoy just seeing it!.
Regards,
