Development of Wind Devices

After looking at few models of Savonius wind turbines, I began working on my own iteration of these types of turbines. due to the possibility of fabrication of these by lasercutting, These are my drawing which I will be cutting myself. The precision may not be as accurate, but the intention of capturing the wind still will be. I intend on making several types which will help me determine and research which is most effective as well as suitable for the proposed site and building that I have chosen.
