Qingdao Greef New Energy Equipment Co. Ltd. is based in China and lists products on Global Trade Plaza, including the Vertical Axis Wind Generator. This product is described as a type of wind generator with a vertically oriented main rotor shaft, known as a VAWT. VAWTs can be packed closer together in wind farms, are smaller, rugged, quiet, light, omni-directional, and create less stress on support structures. They require less wind to generate power, making them suitable for urban installation, rooftop placement, and similar tall structures, and are easily maintained.
