Rotors from plastic gutters
By hvirtane, Section Homebrewed Electricity Posted on Wed Nov 19, 2003 at 02:26:30 PM MST
simple rotors

This 3 page file consists of a two page translated extract from a Danish school textbook from 1988 by O.A. Oksbjerg. The textbook is for 11-15 years-old school pupils on the construction of small wind turbine generators and electronic wind speed measuring equipment.
Plus an an additional download page from the net.
With best wishes to all from John Furze
