The Turby Wind Turbine is the generic term for any vertical axis windmill that has a helical shaped blade.Itwas specifically designed to address the unique problems associated with producing electricity in urban or suburban areas where often a horizontal wind becomes vertical when encountering a building. This type of wind renders any roof mounted horizontal or propeller type of wind turbine useless.

Why the Turby is Unique

Vertical axis turbines like the Turby have been used for centuries and offer several advantages over their horizontal axis cousins in both cost and efficiency. Its helical shaped bladeis cleverly designed to quietly utilize vertical or horizontal wind bursts coming from any direction. This makes it nearly ideal for rooftop electricity production.

Don’t Fight the Wind

Most other vertical turbine designs utilize a blade or wind scoop that captures the passing wind by blocking it and thereby spinning the rotor. The drawback to this style of design is that the very fact that the scoop is solid means that as it spins it has to move air out of the way. This action creates drag and actually wastes energy.

Non-Turby designs also suffer from a high rotational threshold. Simply put, these windmills need a stronger wind to start their rotations. This means that they will miss a portion of the passing wind if it is below a certain speed. It also means that even the wind they do catch is not fully converted to power since some is wasted in getting them to start spinning.

How Much Electricity Will The Turby Wind Turbine Produce?

Theoretically it can produce enough electrical energy to run an entire household. In reality it depends on the consistency and intensity of the wind. This will vary greatly depending on where in the world you live as well as the shape and position of surrounding buildings. Obviously on windless days windmills will not produce any power.

Solar Power Assistance

Rooftop mounted solar panels that convert sunlight directly to electricity are often an ideal compliment to wind turbines. Regardless of the wind conditions they will still produce clean power.

Of course, the drawback to solar energy is that often there isn’t quite enough rooftop real estate to support enough solar cells to cover all the needs of a typical home. Dark stormy days also cut down their productivity.

What Happens When Too much Electricity Is Produced?

This is a great problem because often power companies will set up the electric meter to run backwards if power is being added to the grid. In other situations the payment is rendered in the form of credits for future electricity or even a check. The key is to check with the individual power company for their specific policy.

How long Does It Take To Pay Off The Investment?

This, of course, depends on many factors such as wind conditions, the cost of electricity and the cost of theturbine plus installation. The cost, in rough numbers, is about $10,000 – $15,000 USD andit will take about 8 years to pay for itself in electricity savings.

Build Your Own Windmill Options To The Rescue

In an effort to counter the high initial cost and relatively long payback times, a movement of determined individuals has taken the steps to build their own horizontal axis wind turbines for as little as a few hundred dollars using recycled and used parts. The wonderful thing about this option is that besides cutting your electrical bill using renewable, non-polluting wind energy is that the payback can be in as little as just a month with the right conditions. The downside is that it is less efficient and can generate more noise.

It will be exciting when the Turby vertical wind turbines are found on every rooftop and cost no more than an average kitchen appliance.
