Updated : Good vibrations: bladeless turbines could bring wind power to your home

Skybrators’ generate clean energy without environmental impact of large windfarms, say green pioneers

No more ugly windmills, although I didn't find them unattractive, as I'm a tech guy, but this new type is even better. 

The giant windfarms that line hills and coastlines are not the only way to harness the power of the wind, say green energy pioneers who plan to reinvent wind power by forgoing the need for turbine towers, blades – and even wind.

“We are not against traditional windfarms,” says David Yáñez, the inventor of Vortex Bladeless. His six-person startup, based just outside Madrid, has pioneered a turbine design that can harness energy from winds without the sweeping white blades considered synonymous with wind power

 The Future of Solid State Wind Energy - No More Blades

Wind technology is super exciting, but the vortex induced vibration resonant wind generator intrigued me the most: its just a pole sticking out of the ground which vibrates with the wind. Have you ever seen a flag pole violently shaking in the wind, even with no flag on? Well, it's a lot more complicated than that as it works by tuning in to resonant frequencies, but it struck me as being the most simple type of generator, although this isn't true when you look at the science. 

It's easy to fit the small versions of these on your roof, and they will work night and day. There's probably always sufficient wind to drive them, but as these technologies come down in price, it's possible that many people will opt for solar as well, then you will have full cover. But noise might be an issue in residential areas, especially with the Vortex vibration type.

Now all of this power could be fed back into the National Grid, but lots of people can't afford this technology, and the environment can't wait, so I think this is something the government could be involved in. It will save the country an enormous amount of money, and could give the UK an economic advantage. I think it's win, win. I know there can be backhanders and corruption between government and private industry, especially with the Conservatives, but China manages to do it, and is leaving the West behind. With an open government it can be done. Modern Money Theory (MMT) shows the way when it comes to funding.

Dubious physics claim... is Elon Musk funding this?

Peter Pan said...

Finding an alternative to enormous turbines would be welcome... but is it feasible?

It did look a bit like an advert, I agree, but the other I had lined up got too complicated. I might put it out, though, or find something else.

Peter Pan said...

May as well post it, because this is looking like a scam.

Kaivey said...

I've updated it as the other one was obviously an advert. This one is more technical too.

More details, but it hasn't allowed me to reach a conclusion.
Less efficiency is offset by lower manufacturing and maintenance costs.
