Hello, I have just been granted utility patent on Streamline Wing Propeller GM/P/2015/0001 by the Gambia Intellectual Office, West Africa. This invention is a universal blade that can function in fans, turbines, drones, helicopters and as the fixed wings of aircraft and submarines. I produces less noise and is more dynamic that regular models. Looking for collaborators in US-UK for futher development, production and marketing. A short video of it as a wind turbine is available on terms to be agreed after further discussion.
