Our Turbine that had the most power was our small one made out of cut up pop cans with a small dowel. It had the most power by default. The other didn't work. Ours was short and thin, looked like it could have been a scale model. The limitations of our model were that it wasn't heavy enough to support itself, and slid around. The other just wasn't glued well and had a smaller blade than the others. Airplanes and Windmills work by a change in air pressure. Airplanes also have small blades that come off of the end that catch the wind at a proper angle to cause lift. That same property can be applied to windmills. It has a slant on one side of the blade, which allows it to catch wind and not lose a lot of air. That is why it is necessary to have the rotor blades at an angle. The sail on a sailboat is long and thin, just like a successful rotor. It also has a slight angle, and catches the wind. On the correct angle, it is caught by the wind and moves, just as a windmill catches the wind and spins.
