I Don't Like Windmills. Too often located in "wind tunnels" desired by birds. That said it pleases Moi to share https://www.yahoo.com/news/could-wobbly-wind-turbines-power-161537314.html Could 'wobbly' wind turbines power future homes?Wed, May 26, 2021, 9:15 AM This is a bladeless wind turbine. This is the man who invented them - David Yanez and it could be a wind energy game changer. The turbine is a slender, vertical and simple piece of machinery that instead of rotating or spinning, oscillates collecting the kinetic energy of the wind and transforms it into electricity at approximately 30% of the cost of conventional wind energy sources. CO-FOUNDER OF VORTEX BLADELESS AND INVENTOR OF BLADELESS WIND TURBINE TECHNOLOGY, DAVID YANEZ SAYING: "What we want is to try to find a niche that is not properly covered by conventional wind power. The niche that in principle we see could be small wind industry, because the absence of maintenance, no need for oil and the low cost could be the elements that make this idea a useful tool for distributing energy, producing energy close to the point of consumption." His start-up, called Vortex Bladeless, was born in 2015. Their latest prototype measures 9 feet and 33 inches and are aimed at being used in urban centres, either on their own or in conjunction with solar panels. "For all those urban centres that do not have as much solar resources as Spain and the whole Mediterranean area, the urban environment seems to fit perfectly with this idea. The fact it does not produce noise, the visual impact is subjective, but there are those who consider that it could have some attraction, better than those of the conventional wind industry." Yanez estimates that with a suitable investor they could commercialize their prototypes in 12 to 18 months. In the long-term, he hope is that his invention can be used in the off-shore wind industry.

I wonder what its' downside is Any ideas? Moi Across an immense, unguarded, ethereal border, Canadians, cool and unsympathetic, regard our America with envious eyes and slowly and surely draw their plans against us.
I don't know of any downside other than these turbines currently don't generate much energy. They don't require gears, brakes, or oil so they are cheap to manufacture. Vortex Bladeless Turbine - Reinventing wind energy! The top portion, which is about 75% of the height, vibrates back and forth. The bottom 25% is the base.
"They" acknowledge a windmill based on wobble will not produce as much as the standard style. But, that is offset by cheaper costs.
The lack of significant movement might reduce objections due to bird strikes, aesthetics and perhaps noise and maybe maintenance will be less.
Even with ideal turbines and extremely high efficiencies, wind power is barely competitive. And even then it will always been virtually insignificant as an energy supply. At best it can only produce a small fraction of the energy needed every day, Now make it far less efficient and you have nothing of value. But it is kind of cool as artwork. They look like industrial trees in a post-apocalyptic landscape.
Today, the single fuel producing the most electricity in Iowa is ... ... wind. Also, making a single pylon less efficient does not necessarily reduce the total output of a wind farm. Pylons might be able to be placed closer together, are probably cheaper, and may be adaptable to locations where bladed pylons aren't going to work.
Iowa has a lot of land and very few people. Do the math nationally. It is a drop in the bucket at most. Turbineless will never be economical. Like I said, even the best turbines can barely compete now. Almost every alternative form of energy has failed because it isn't economically viable. Many that survive like ethanol from corn, only do so because of government subsidies.
Yes, it's important to consider America as a whole. The point with Iowa is that it IS economically viable. That's not controverted by the size of their population. Today, renewable energy production is growing at the rate of the growth in our demand for electricity. There are major projects being constructed throughout the central region of the US, from Texas to North Dakota. There are many other states that are seeing this growth, too. I would add that solar has serious potential now, too, as it has become cost effective with the rapidly improve efficiencies that have come over the last few years. Consider the combined roof top space of buildings in America, for example. A significant number of those owners could be producing electricity, thus reducing their power bills - as well as displacing point source fossil fuel electricity by some percent. This has NOTHING to do with corn - except that those who farm every acre of our corn could add an additional revenue stream in the form of wind energy proceeds.
I hope so. But, I don't react to technology articles by swallowing everything they say about likely performance in a production environment.
I never disputed that. I said it is barely economically viable, meaning that is barely beats the costs of traditional energy sources. You are mixing apples and oranges and going completely off the rails. I said turbineless wind will never be competitive. The reason is that is by definition far less efficient. You can't cheat the law that the lowest cost per KWHr wins.
Fewer moving parts is usually a good thing for maintenance. But, calling that proof is as ridiculous as assuming I didn't read the article.
They take much more real estate per BTU produced than nuclear. I'm fond of expanding nuclear technology.
I truly prefer HYDROGEN Water, even salt water, a source of solar powered electrolysis of water and harvesting the HYDROGEN. Sadly Hydrogen is not so dependent on a central grid. So, Hydrogen is sequestered Get It Or Not Moi Alberta Open Mine for a Green Tomorrow Get It Or Not!
Hydrogen is much like fossil fuels and unlike solar and wind in that it can be efficiently transported long distances. I like those, too.
Hydrogen is nothing like EITHER of those, as hydrogen is merely a transport solution while oil, coal, gas, solar and wind are actual energy sources. Hydrogen is a storage methodology.
