Abstract: A vertical axis wind turbine (VAWT) with improved and optimized wind-directing, wind-shaping, and wind-power conversion features is disclosed. The shapes of these features directly affect the ability of the VAWT to use the power of moving air, such as wind, to spin a rotor and create torque on a rotor shaft to generate electricity. The wind-power-conversion mechanical efficiency of the invention is significantly improved over previous efforts, to the point that the invention can convert wind energy into electrical power at a price-to-performance ratio that competes with or surpasses existing alternative energy technologies.

Abstract: An apparatus for blending materials and dispensing the blended materials generally includes a housing, a tip moveably coupled to the housing for dispensing blended materials from the apparatus, and first and second intake units supported by the body and arranged in a generally Y-configuration. The first intake unit has a mixing tube defining a channel for transporting a first material to the tip, and the second intake unit has a mixing tube defining a channel for transporting a second material to the tip for blending with the first material. The first and second intake units also each include a seal coupled to the mixing tube and configured to wrap around a portion of the tip to thereby seal the channel of the mixing tube against the tip.

Abstract: A cover is provided for installing at least partly around an electronic device. And, a module is provided for releasably coupling to the cover. The module includes a compartment for storing desired items within the module when the module is coupled to the cover. An insert is associated with the cover for use in releasably coupling the module to the cover. In particular, the insert includes arms that extend through a back portion of the cover for use in releasably coupling the module to the cover. In some aspects, a mounting unit is also provided for supporting the cover and the electronic device in a desired position (e.g., on a bike, in a vehicle, on a boats, on a belt strap, on a backpack strap, etc.).
