The centrifugal force required to compress the air is too great for small wind turbines to cope with, so much larger turbines will have to be installed for the project to realize its goals.
Despite this rule of thumb, there is a burgeoning movement to bring small-wind power to cities as well.
According to Motorwave, the new technology can reduce energy bills by up to 50 percent and costs between 10 and 20 per cent of current small wind turbine systems to run.
Conventional small wind turbines only work 20 percent to 40 percent of the time due to variations in wind speed, according to the Department of Mechanical Engineering of The University of Hong Kong and Motorwave.
The website lists rebates and other subsidies that help to defray installation costs and provides a calculator for figuring out the cost of electricity, the payback period and the return on the investment from installing small wind turbines, which refer to those that are under 100-kilowatt in size and engineered for residential and business properties, including farms and government agencies.

National Grid announced an agreement Thursday to buy power from a small project set to be built by Deepwater Wind near Block Island, R.
For example, if you plan to add geothermal heat pumps, residential small wind turbines or solar energy systems, the credit is equal to 30% of the cost with no upper limit.

Subsidiary MEG Renewables is now seeking sites to develop and operate small to medium-scale wind turbines.
There's currently only a single wind turbine on a small outer island providing energy to Hong Kong, the rest of the city just doesn't get enough wind for traditional turbines to do any good.
ENGADGET: Micro-turbines output micro-electricity for Hong Kong's micro-apartments
But decisions by some states to cut funding have contributed to a decline of small wind turbine installations.

Stand up, Caleb, so we can see you. (Applause.) Caleb built a wind turbine that's small and fast enough to be installed on your roof or in your front yard.
WHITEHOUSE: President Obama Speaks at the 2013 White House Science Fair
As we speak, old factories are reopening to produce wind turbines, people are going back to work installing energy-efficient windows, and small businesses are making solar panels.

That's why, if you're selling options, you're likely to wind up with a succession of small profits punctuated by the occasional big loss.
At the same time, their small and often dilapidated vessels can easily succumb to the wind-whipped waves formed in the lake by its volatile microclimate.
Since the Development League launched in 2001, 177 players have been called up to the NBA, but only a small number wind up with a guaranteed deal.
Effects stemming from the Earth's atmosphere, from ocean tides and from the solar wind of charged particles were all found to be too small to explain the spacecrafts' extra velocity.
He set about making a wind tunnel in his garage and placed small shields on toy school buses to test them.
FORBES: How One Kid Can Make A Difference For The Environment
As early as the late 1980s Quantum Corp. saw which way the wind was blowing and attempted to reposition itself away from its traditional business of supplying small disk drives to PC manufacturers.
The small, local combined-heat-and-power stations and wind turbines do receive subsidies in order to survive in competition with the big power stations.
Earlier this year, the spectacular bird was again in the eye of an Australian storm, this time over another, larger wind park in Victoria, even though research had suggested that the threat to parrots is small.
One of the ironies of the power crisis is that, instead of profiting from increased prices, small generators that use renewable sources of energy such as the wind and the sun have been driven almost to collapse by the failure of the utilities to pay them.
To get clean energy to them requires a decentralised approach using local resources such as wind power, solar energy or small hydroelectric projects.
Then, if you are sufficiently small, you may be lucky enough to be hurled aloft in the spray, and swept upwards by the wind.
And there is no question that when it comes to protecting seniors on Medicare, when it comes to protecting businesses, small and large, that are part of our renewable energy sector, especially wind energy, that this President has been making very strong policy arguments, and that at a substantive level as well as at a level of support from the American people, he's winning those arguments.
Second, governments should not pick winners or give out extensive subsidies. (Translation: Ethanol is a bad idea, and other existing "renewables, " such as wind power, are unlikely to ever be more than a niche source.) Better to have a small carbon tax to place a price floor for competing technologies, and offer large cash prizes, similar to the X-Prize for private space flight, for specified energy breakthroughs.
