Hello World’s Ashlee Vance paid a recent visit to Iceland’s capital city of Reykjavik to see the next part of the green energy story. He found a start-up called Icewind that is building a new type of funky wind turbine designed to perform well in low-wind conditions but also to slow itself down in high-winds, preventing it from catching on fire or ripping apart.

"One of Wind Power's Biggest Problems I thought that this videos would be about the slaughter of birds. I moved to the Columbia Hills (which flank the Columbia River in Washington State) in 2000. In 2000, anytime one looked at the sky one saw hawks and eagles circling; when driving down a country road paralleling the Columbia Hills, it seemed as if there was a raptor perched on every telephone poll. Then they built the wind farms. Now all the hawks and eagles are GONE, slaughtered by the wind turbines. WIND TURBINES ARE EVIL. Or, perhaps I should say, conventional wind turbines are evil. It looks like this design will prevent bird-kill. Perhaps it will replace conventional turbines, for efficiency reasons. DISMANTLE ALL CONVENTIONAL WIND TURBINES!!
Wind turbines currently in use are serious noise polluters, people can't stand to live near one. And they are infamous bird killers.
There are people who's lives are ruined when those wind turbines are built near their homes, from the horrible noise, and they can't sell their homes and move: no one will buy them, because of the noise.
This would be great here in the Mojave desert. Even in low wind conditions it's still wind!! This would definitely give the energy company a run for it's money. I would love to have one in my backyard and get off the grid.
You have to be pretty stupid to think "most people don't even know what it is. They think it is a sculpture or something..." Fucking idiot. That or people in Iceland are retarded. I am going to go with the "former nuclear engineer" that now makes turbines out of a small shop. Probably why he is a former nuclear engineer. lmfao
They should just put gears on the conventional turbines so that there is more resistance in faster wind. That the gears would just generate more power, while slowing down the turbine. A gliding transition like some Mitsubishis have.
NREL National Renewable Energy Labs (US) stopped all testing on VAWTs because of inefficiency, unreliability and high cost of maintenance. I live close to an NREL test site near Boulder, CO. There are many standard 3 blade designs that undergo testing. As a hobby, I did a lot of research into renewable energy, especially wind turbines. Despite looking cool, I discovered that the VAWTs were essentially worthless.
It is not even close to being a new idea. Google Savonius turbine. The Savonius wind turbine was invented by the Finnish engineer Sigurd Johannes Savonius in 1922. The Savonious gets less efficient the higher the wind speed goes. It is fine for low speed things like water pumping or low power needs, but is very low efficiency compared to conventional turbines. The fact that it starts spinning in low wind is useless, because there is nearly no usable power in low wind speeds. The power available in wind goes up as the cube of the windspeed, so doubling the windspeed gives you 8 times as much power. 7.5 minutes of 8mph wind is worth 1 hour of 4mph wind is worth 8 hours of 2mph.
BTW this is not even close to windpower's biggest problem, storing electricity for when you need it is.
The problem with this tech is that it can't be built GRANDE without also having a netted cage around it which must be as big as the wheel itself if it's to be mounted anywhere near where people or animals live.
In its current design, it's a so called "Bird-eater/exterminator". . ;)
We have the same problem with the "S"-shaped vertical windmill. Excellent tech, but Seriously Dangerous to everyone around it. Many little kids fingers have been eaten by that one. ;)
You know how they keep saying that eagles get killed by the big windmills ? ( I think it just opponents of windmills that are saying it ) it would take a very stupid bird to kill itself on one of these type. in fact I don't think anyone would believe it if they said these were killing anything.
well I don't know about you, but I definitely want one of these bad boys at my house, in fact I want a dozen ! :D
Coal miners lives and livelihoods could be saved if the USA, rather the United Soviet Alliance, admits climate change is real and actually does something to improve the lives of coal miners. Wait for the impeachment and subsequent jail sentence of the orange habitual liar in the extremely white White House
Always worth pointing out that CO2 comprises just 1/25th part of ONE percent of the Earth's atmosphere...and that the dominant 'greenhouse gas' water vapour at around FOUR percent is in limitless supply.
Great, now how big do they hav to be to generate grid levels of power?
Look at the bus stop, two big units to power a wifi hotspot and phone charger? How friggin' big would they have to be to power a whole home? Or a neighbourhood?
Rocks too are cheap, can endure hard weather and rarely overspin. What's the damn efficiency on these things? Poor reporting, immoral actually- money wasted on spinning bullshit are money not spent on actual energy solutions
It is possible. Energy generation is currently centralised. If every household has one of these as standard then energy would become like the internet. The internet is a composite of millions of servers linked around the world. You just do the same for devices that are installed on individual properties. The problem is that energy companies are so well established and monopolise the energy market. Also there is no way to monetise energy if all everyone needs to do is make a one off purchase every 10 or so years. It is nothing to do with anything else other than economics and energy companies maintaining their billions of dollars in profits.
It could become thousands of birds per year if those things are put all over the world. How'd u like it if you were standing there waiting for your bus, drinking your triple latte mocha cappuccino when a pigeon head flies into your cup?
For small-scale power under 1 kW...the turbine on fire was a megawatt class. In other words 1-3 thousand times the capacity. also, the footage on the Enercon Turbine was speeded up those blades spin at under 20 rpm. Great for an eye-catching small-scale local power not large generation. Also in Iceland, there is a surplus of energy from geothermal sources no need for wind or sun. Been in wind and renewables a while now we keep reinventing the same wheel
This is a crappy Savonius turbine, the least efficient form of wind generator. It's not a solution, it's a multiply tried failure except for the most trivial of power needs. It's been around for thousands of years in one form or another. There is nothing innovative about it.
To Bloomberg: The manufacturing process seems simple so how does Icewind compete against e.g. a Chinese manufacturer, especially if it is based in Reykjavik (one of the most expensive places in the world)? Patents? Aerodynamics know-how?
