Counter rotation 3d printed portable wind turbines

New innovative portable counter-rotating wind turbines with high power generation capacity. A new concept of counter rotation devices including vertical and horizontal versions. It has been developed a planetary gearbox system that provides a higher torque and more improved efficiency with a new innovative design that for a portable wind turbine is able to multiply the RPM of the generator/s by 8. This gearbox system also avoids gears backlash and provides a high power density with a light weight & compact design that occupies less space. The device can be configure to expand the diameter of the turbine blades therefore achieving more torque or it can be shortened and reduced to a one single conventional turbine blade ring in order to obtain more rpm with strong winds conditions. It is very easy to assemble and it can be taken to any place disassembling it. It can use different type of DC/AC motors for ranges from 50W up to 350W and there is a version that can hold up to 4 DC/AC motors. Available in digital and physical versions.
