Good day. I would so much like to get in touch with a knowledgeable guy better still an expert in the field of the Savonius turbine. I designed a Savonius and my key word was not it must be cheap. My key words was " It must be Efficient and reliable and no shortcuts taken and all the problems of the Savonius must be addressed. I achieved at least 90% of it. I have build a very rugged model that can be tested. Swept area is 0.6 x 0.9 meter. I want to invite all the experts and interested people to come and evaluate the design and maybe we can create an interest group. I am from Claremont Pretoria. Hennie Stander 0725621591
