Hello. My name is Robert, im 30 and i have been an inventor for 10 years. I have been developing ideas to the thinnest details. Unfortunately, my life was a little hard and i don't have a mechanical/physical/electrical/ background. But i get a lot work done without that. I design 3D's of some of my projects, even tried some animations, but keep getting stuck with free versions of programs.... I want to talk with some experts in diy field, i want to start my projects and make some prototypes, i even plan on buying a 3D printer. Up in the picture is my first project for presentation, a water turbine for river bottoms with a water flow blocker, or it can be used as a VAWT, in the picture bellow, with a blocker that moves (rotates on a bearing using wind fin) Air, water, who cares, as long as it gives green power. The blocker is used to stop the water/air forcing the turbine in the wrong direction. Ok, so This is enough for today, i have a lot of amasing stuff, and this is just one design, i would really like some comments, so, please, comment. Thanks for reading. Edit: Just realized that the system with the fin can be used on river bottoms with changing flow directions..
