Bladeless turbines that waggles like a dashboard toy could be the wind-harnessing tool of the future as they move within the range of vibration of the wind to generate electricity.
The design recently won the approval of Norway’s state energy company Equinor, which named Vortex on a list of the 10 most exciting startups within the energy sector

How do they mitigate noise? A seatbelt vibrating in a car’s wind is deafening.
“The Vortex Tacoma (2,75m) estimated rated power output is 100w once industrialised.” (sic)”
Forget wind water is 800 times denser than air put a 2.75 meter polymer based version under water in a flowing stream and it should generate 800 times more energy per sqcm of surface area.
Wind also scales at the cube root of wind speed the difference in power from 2 to 4 meters per second is not double it’s 8 times.
“The Power of the Wind: Cube of Wind Speed
The wind speed is extremely important for the amount of energy a wind turbine can convert to electricity: The energy content of the wind varies with the cube (the third power) of the average wind speed, e.g. if the wind speed is twice as high it contains 2 3 = 2 x 2 x 2 = eight times as much energy.”
Metal only fails via fatigue if its fatigue limit stress is exceeded under that stress level an unlimited number of cycles is possible for metals of ferrous alloys, titanium or nickel based alloys. A good example is valve springs in a diesel class.8 engine if run under moderate conditions they will last 10^9+ full open close compression cycles which is million miles this metal being flexed over its full flex range 1800 times per minute for days or weeks at a time under high heat conditions. Metal flexture is an engineering issue one that humans solved hundreds of years ago. The life span of something that flexes slowly in the wind would also be expected to be in the 10^9 or more range which means decades if not centuries again effectively unlimited flex cycles as the physics would expect it to be.
Plus, they astronauts on the ISS can touch them as they pass by.
I’m not against the idea of renewables, but we need to be honest about their limits and whether or not we can bridge the gaps that still remain between energy generation and storing the energy.
We don’t have the ability, for example, of shutting down the power plants for a day, so we can switch to the batteries that have stored the energy from renewables, for that free energy, and then turn on the powerplants again while we wait for another time when we have stored enough free energy for another day off.
It’s all kubuki theatre if we can’t bridge that gap.
For me, renewables have a place, in your home, for power back up. As long as the power is up, you use the powerplants. However, if there is a black out, you can switch to the energy you stored in generators that came from solar or wind power or hydroelectric, if you have a stream on your property.
But that’s really the limit as to where we are at.
“Yeah, Great! But can it shred birds?”
Oh Chef of the future, it can shred birds. And it can core a apple.
Someone didn’t think ahead.
Could have saved taxpayers a lot of money. Must have been dimocRATS!
I have a small Dyson fan in the bedroom. Adjustable and so quiet. Better than a overhead fan. You can direct it to flow over you and not on you. I like that very much.
Never will I have to clean those nasty blades again.
LOL! Thanks for the input.
LOL! Thanks for the input.
I’m sure the wildlife will adapt well to the constant vibration of the surrounding area.
-”Even if you turned it “off” it just turned off the video output and still used 42 watts. “
You made me extra curious, so I checked.
I recall older instant-on TVs had HUGE parasitic losses.
My big surprise was the GFCIs ~5 W!
TV 0.33 W OFF
Cable box ~17.5 W constantly fluctuates.
WiFI box ~24 W power own and operating.
Wall wart for streaming at. 2.2 W.OFF
Approx 45W!
Old rule of thumb: 1 Watt used for 24/7/365= 1 dollar.
Close.
When you go to the dealership some night with a pellet gun to put holes in the thing, you might see a car in the show room you like?
It's bait.......LOL!
Localized earthquakes, anyone?!?!
People who live near the current crop of wind turbines claim that the ceaseless vibration actually shakes stuff off their shelves. The 'Skybrator' will be even better - I'm sure.
—”Magnus Effect is another “Blade-less” Turbine!”
I recall the Magnus Effect!
From this video:

Not generating electric, but fun stuff!
And that airplane!!!

I worked with a handful of people that lived near wind farms.
Some could hear”something”, others nothing at all?
All received a monthly compensation check from the utility.
—”They’re also very cagey about exactly how the alternator works: it’s patented and does not use any gears or bearings or circular motion. “

It is out there...
I see all these great breakthroughs, why doesnt anyone look into redesigning a carbon free coal plant? And as a backup, plants thousands of trees to absorb the CO2 coming from liberals mouths!
According to the video the device was “likened to a giant sex toy, the skybrator”. It’s bound to be a sexsess
Think of the possibilities...
