This is the third vertical wind turbine I
built. It is called a "Lenz" turbine by the
This one is about 2' diameter and the blades
are 8" high. (I run out of the wider pieces of sheet metal on
the last turbine) The two sets of blades are mounted at an
offset. Like the regular Savonius this one has the metal folded over
the edges of the wooden forms and then riveted and fiberglassed to ensure
no water gets anywhere it's not supposed to be.
holding the blades are pieces of fiberglass tent poles I had from an old
torn up tent someone gave me. they are screwed to the wooden blade
forms and also fiberglassed solid.
