Harnessing wind power for use in residential applications has been a challenge, but a new breed of vertical axis wind turbine (VAWT) from Helix Wind offers a promising design that may change the way we do wind at home. The Helix Wind Savonious 2.0 uses a unique rotor capable of capturing omni-directional winds to provide quieter, kinder small wind power for your urban home.

The Helix Wind Savonious 2.0 is a 2kW rated turbine that can be tower-mounted between 14 and 35 feet or roof mounted just 2 feet above roof line. The rotor measures 6ft by 4ft (1.8m by 1.2m) and utilizes long helical blade scoops to maximize energy performance in turbulent, gusty or multi-directional wind conditions.

The capabilities of the rotor to spin in any wind make it ideal for urban settings. The combination of lower height and quieter action make Helix’s turbine more neighbor and zoning commission friendly. As far as noise, the Helix Savonious 2.0 operates at less than 5 decibels above background noise.

And there’s good news for the bird lover in all of us – the Helix is safer for wildlife. The rotor spins at much slower speeds than horizontal turbines and both birds and bats recognize the rotor as a solid object. Bird-blade collisions are mostly a concern in “big” wind but the fact that the Helix rotor doesn’t fatally confuse our feathered friends is a big plus.

At present, the Helix Savonious 2.0 is undergoing evaluation for UL and cUL listings to make it eligible for rebates under all state Renewable Energy Programs. The base price for the Helix Savonious 2.0 is $6,500 before tower and installation. A low wind version starts at $8,500 and a larger 5kW model starts at $16,500.
