Great to find a product that is new, different and actually available (in North America anyway). It's a 'Magnetically-Levitated Axial Flux Alternator Vertical Axis Wind Turbine' which really runs best on a rooftop. Impressive.

This new prototype turbine, called Stormblade, works by accelerating the wind onto the blades and is therefore more efficient at low as well as high wind speeds. It's bird- and bat-friendly too.

more...A miniature urban wind farm is being built on top of a 13-storey building in Manchester city centre using micro wind turbines.
The 24 turbines, which will stand 3m tall, will be erected on top of the CIS building on Portland Street. The turbines will produce 56,000 units of renewable energy each year, enough electricity to service about 5% of the energy needs of the building.

Interesting piece in the Guardian about a new mini wind turbine made in Scotland by Windsave. Its said to produce 1kW in a 12 m/s wind. In our case it would only contribute a little, but at only £750 its worth it if only to experiment with and offset a little of the increased electricity use with the heat pump. What makes it possible for Hedgerley is that it is barely above the roof height, doesnt require planning permission and plugs straight into the existing electricity meter.

The basic wind story looks pretty promising. If an average house uses around 10,000 kWh a year, then a 5 - 15 kW turbine can made a sigficant contribution to this. A 10 kW turbine, for example, would cost around 20,000 pounds and payback in 15 years. A turbine operates in winds over 10 mph and typically produces in an average year 30% of its potential output. This suggests that if it runs successfully for 30% of the year (say 100 days) it should produce 100 x 24 x 10 kWhs = 24,000 kWhs.

Domestic wind turbines have been described as "the new handbags" - the latest luxury items craved by those who want to be first to try new technology. But this description overlooks their green credentials, because any electricity powered by the elements is reducing CO2 emissions, which are blamed for global warming. And there are also the financial motivations.
A household with a windmill can save money on bills and sell excess electricity back to the national grid. So could wind turbines become a nice little earner?
They are certainly on the increase - 7,000 households have been given grants to get the turbines installed.
