History of wind power - Wikipedia

In 1931 the Darrieus wind turbine was invented, with its vertical axis providing a different mix of design tradeoffs from the conventional horizontal-axis wind turbine. The vertical orientation accepts wind from any direction with no need for adjustments, and the heavy generator and gearbox equipment can rest on the ground instead of atop a tower.

Jul 17, 2012· UGE's vertical turbine tests out at a 43dB, which is slightly lower than a normal conversation heard from a few feet away (53dB). A vertical turbine casts a much smaller shadow than a propeller type turbine, because its wind gathering aspect is more compact in three dimensions, and as a result produces little visual effect.

The truth about Vertical Axis turbines | Hugh Piggott's blog

Vertical axis turbines were among the earliest invented but they got replaced by horizontal axis because (like a sailing ship) the wind always comes from one side of the sail and is steady, so the turbine works smoothly and is not buffeted by cyclical stresses. So they stopped making vertical axis for good reasons.

GreenSpec: Energy: Small / Domestic Wind Turbines - 1 - 6 kW

• The installed costs of small scale turbines can vary from around £2,500 for a 1.5kW rated turbine though to around £5,000 for a 5kW. • The payback time is the amount of time it takes to pay for the installation through electricity saved from the grid – a time after which electricity becomes free.
