Charging electronic devices during long periods away from civilization remains a difficult task.So far, solar panels are the only available solution to this common problem, making the power supply completely dependent on weather periods with sufficient sunshine.
The Micro Wind Turbine is a portable energy source for remote regions and enables people to charge USB devices far away from civilization. It weights less than one kilogram, folds down to the size of a trekking pole and can operate day and night.
The shape of the vertical axis rotor is based on an optimized Savonius turbine, a simple yet versatile device that can operate in a wide range of different locations and wind speeds.
It is very suitable for unsteady and gusty winds and the sails can catch wind from all directions without the need for a pointing mechanism or external regulation.
With a weight of less than one kilogram it is 40 percent lighter than the closest competitor and has a significantly bigger rotor that enables a high output even at low wind speeds.
