We are developing an innovative new micro wind turbine. The goal of the HomeTurbine is to create a reliable and effective decentralized energy supply. The patented design is aiming for a turbine which is able to perform well in the urban environment. A small scale model prototype has already been tested in a windtunnel. This gave us insight into the airflows in and around the windturbine. The knowledge we gained by testing has been used to make a full scale prototype which is currently being tested.
