Turbine blades for small-scale wind turbines are typically 1.5 to 3.5 metres (4 ft 11 in – 11 ft 6 in) in diameter and produce 0.5-10 kW at their optimal wind speed. [1] Most small wind turbines are horizontal-axis wind turbines , [ 2 ] but vertical axis wind turbines (VAWTs) may have benefits in maintenance and placement, although they are ...
The generator, which is approximately 34% of the wind turbine cost, includes the electrical generator, [64] [65] the control electronics, and most likely a gearbox (e.g., planetary gear box), [66] adjustable-speed drive, or continuously variable transmission [67] component for converting the low-speed incoming rotation to high-speed rotation ...

If however the rotor to exit area ratio is 2.75 (as it was in the Grumman case), the actual power increase over a HAWT with the same swept area as the diffuser exit area is only 1.4× the power (a Cp of .34 related to the exit area, slightly better than a small unducted wind turbine and significantly worse than utility scale wind turbine Cp's).

Saphon Energy announced a bladeless wind turbine in 2012. [27] Vortex Bladeless is attempting to produce a wind turbine that isn't actually a turbine. All generators require a magnetic field, a conductor and motion to produce electricity. A small generator can only produce a small amount of power. It takes a lot of energy (movement) to make a ...

Domestic microgeneration technologies include: photovoltaic solar systems, small-scale wind turbines, micro combined heat and power installations, biodiesel and biogas. A small Quietrevolution QR5 Gorlov type vertical axis wind turbine in Bristol, England. Measuring 3 m in diameter and 5 m high, it has a nameplate rating of 6.5 kW to the grid.
