The Sheerwind Invelox wind turbine promises to produce 6 times more electrical power than traditional wind turbines.
This unique wind tower acts like a funnel, directing the wind from any angle, down through a tube to a ground-based turbine generator. The funneling of the wind through a narrow passage effectively creates a “jet effect” increasing the velocity of the wind, while lowering the pressure. This is called the Venturi Effect. This speeds up the wind turbine mounted inside the narrowest portion and generates electricity.
As such it can capture and generate electricity at a much lower wind speed than current wind power technologies.
The idea is so simple, so elegant, and promises to produce so much more energy at a lower cost and more efficiently, that it might just be the answer to many problems with current wind turbine technology. Aside from the lower capital investment to get started, and increased efficiency and power generation, it also might be a solution to the ever-growing problem of birds (and bats) being killed by traditional wind farms. (Yes, that is a problem)
This technology is not really new in the science of fluid dynamics, however, this is a new way to generate electricity, and if successful, promises to grow wind energy in a more eco-friendly way than ever thought possible.
Imagine a smaller HOME version on your off grid cabin. Now THAT is cool off grid tech!
Conventional wind turbines use massive turbine generator systems mounted on top of a tower. INVELOX, by contrast, funnels wind energy to ground-based generators. Instead of snatching bits of energy from the wind as it passes through the blades of a rotor, wind is captured with a funnel and directed through a tapering passageway that naturally accelerates its flow. This stream of kinetic energy then drives a generator that is installed safely and economically at ground level. – See more at: http://sheerwind.com/technology/how-does-it-work
Update: This article was originally published in 2013. In 2017, Sheerwind filed for bankruptcy and their website is no longer accessible. The technology is still promising, however, and hopefully will find use in the wind energy industry in the future.

Dear offgridworld, When I worked for a very large auto company, I designed HVAC duct that turned 90 deg corners with 70% increase in efficentity in air flow based on the fluid dynamics. It was never patented. You have my phone number and my email. I will show you how to double your power.
