While wind power only makes up about 1% of current world power generation, it is one of the fastest-growing methods to create power. Wind power requires very little maintenance after installation, can be scaled to meet individual or community needs, and creates no emissions or by-products.

Windmills have been in use for over two thousand years, but only in the last 150 years has man harnessed the wind to create electricity. Small wind turbines brought electrification to a large section of rural America. Today many countries rely on wind, solar and other renewable energy resources for a significant fraction of their energy needs.

Creating Electricity from the Wind
The rotational motion of turbine blades driven by the wind is converted to electricity using an generator. On horizontal-axis wind turbines such as SolAir, the generator is located at the top of the Frame in line with the rotating horizontal shaft. On vertical-axis wind turbines, the generator is located at the base of the structure in line with the rotating vertical shaft. The generator uses electromagnetic induction, magnets passing over copper coils, to generate electricity, which can either be used while being produced or stored for later use. The primary source of energy loss in this configuration is friction between the motor and its drive system, which may contain a gearbox. In order to reduce friction and increase efficiency, DyoCore has developed a gear-free, filler-free motor. This unique design reduces the stress and wear on the motor’s moving parts and allows the blades to move smoother and faster at lower wind speeds with less resistance.

Power Generation and Efficiency
Wind turbines are available in small sizes from a few watts for remote on-site electricity needs, up to giant MW generators with a blade diameter of 400 ft or more. The amount of power that can be generated by a wind turbine depends on a variety of factors including wind speed, rotor size and air density (which varies with altitude). Because wind is not a constant resource, wind power generation often contains a capacity factor, usually in the range of 20-40% of the theoretical maximum. The German physicist Albert Betz calculated "that a wind turbine can extract at most 59% of the energy that would otherwise flow through the turbine's cross section", assuming a perfect and frictionless system.

Storing Electricity from Wind Turbines
Wind, despite its benefits, does not provide a constant and continuous input for electricity generation. Because of this, power generated from wind turbines must either be used immediately either locally, within a grid-tie, or stored for later use using batteries. Batteries are used frequently in Small Wind/Solar applications to capture the energy, store and release that energy on demand. SolAir incorporates a Solar film designed into the Fin assembly mounting into the SolAir Frame. This allows constant charging capability during sunlight in no-wind or low-wind conditions and the opposite – no light but wind. The intermittent nature of both wind and solar make them an ideal partner in combination for the purpose of energy collection.
