Bold blade-free turbines opening up future of wind generation

The silhouette of a wind turbine on the horizon is now a familiar sight for most people, and has been at the centre of many conversations regarding the future of renewable energy generation. So what if wind turbines looked nothing like they do now?

That’s a possible future for the wind power generation industry, with the arrival of a whole new design of wind turbine that’s receiving massive support from strangers all over the internet.

The “Vortex Bladeless” wind generator is a deceptively simple structure – tall and conic, with a base that allows it to sway with the wind. This oscillating motion causes ‘vorticity’ (an aerodynamic effect) and is how the Vortex is able to capture energy without the use of rotational turbines.

The project to get this design off the ground is being run by a team of three from the United States. The unique creation was originally dreamt up by David Yanez, who was inspired by a video clip of the Tacoma Narrows Bridge (Washington) oscillating in the wind.

The team took the idea to crowdfunding site IndieGoGo in hopes to raise enough money for a commercial product pilot in India. With hopes of raising $50k, the innovative project has to date raised nearly $70k, from a total of nearly 1,200 backers and donators.

The pilot means that the Vortex can be tested in a number of different locations and conditions, and to find out how well it will work for domestic sites – allowing people of all demographics access to clean, affordable energy.

While it’s still early days for the energy generator, it’s certainly a promising step towards new and exciting ways of leading a more renewable example. We may not see this cropping up within the year, but for now you can read below to find out why so many people were eager to help get this project off the ground.

The Vortex generator in numbers

20 Hz – that’s how quiet the Vortex is, oscillating at a frequency that is barely audible (20 Hz is just about the quietest noise humans can hear).

40% – how much less it costs to install against a comparable traditional wind turbine.

80% – how much less the Vortex weights than a conventional wind turbine. This also means the Vortex can have a much smaller foundation below ground.

0 – how much oil is needed. Wind turbines need a certain amount of maintenance because of the internal gears and moving parts, something not required with Vortex technology.

30% – The Vortex is 30% less efficient in generating energy than a wind turbine.  However, when weighed up against the fact that many more Vortexes can be placed in a smaller area and at a lower cost, more electricity is produced comparably.

100W-400KW – the current energy capacity of Vortex designs in development or production at the moment.

1MW – the energy capacity that the founders are hoping to reach by 2018.
