First Floating Wind Turbine Buoyed Off Norway
MonkeyClicker writes to tell us that the world's first large-scale floating turbine has been installed off the coast of Norway. A combined effort between Siemens and StatoiHydro, this marks the first foray into deeper waters due to restrictions in place that require offshore turbines to be attached to the sea bed. "The turbine in Norway will be 7.4 miles offshore where the water is 721 feet deep. It will be utility-size turbine, with a hub height of about 100 feet, capable of generating 2.3 megawatts of electricity. To address the conditions of the deep sea, the turbine will have a specially designed control system that will seek to dampen the motion from waves."
Of an old saying... "There's power in the motion of the ocean". Though I think that quote referred to something completely different.

Can someone provide me with a credible reason why we shouldn't stack these things on every coast in the world to provide nations with clean electricity? Or is nuclear power still too sexy to give up?
Anybody else craving a Sea Breeze?
Well obviously there's potential there or they wouldn't have gone as far as they have, but I just don't understand how it doesn't tip over instead of spinning, or how they keep it pointed in the right direction. I'd love to see it in person. And I bet they use them in a future Bond film.
No sig for you. YOU GET NO SIG!
For suggesting that a measure of tidal power could be harvested as well here? After all, kites can be used to harvest power through the tension exerted on their cables, if I'm correct. Similarly, these turbines are going to be tethered, right? How about it?
All you need now is a 7.4 mile long extension cord that can survive the ravages of the open sea to plug the dang thing into a power grid.
2.3 Megawatts is fucking nothing, and for $63 million?
I fucking hope the maintenance is low, it won't ever pay itself off otherwise.
place and it never runs because when there is a breeze it doesn't work when its windy it blows over. I have only seen it working twice in two years (and it blew over twice) and it only cost 1 millions dollars already. I could make cheaper power with my 3500 watt Honda generator we use at work.
1. solar power: more than 20 cents/kwh, 10 to 14 cents/kwh
2. wind power: 5 to 7 cents/kwh, 3 to 6 cents/kwh
3. nuclear power: more than 3 cents/kwh, more than 3 cents/kwh
Here, "wind power" refers to wind turbines on land. A wind turbine at sea would surely cost more than a land-based one.
In other worse, nuclear power is still the best solution until we can significantly improve the efficiency of generating solar power and wind power.
We should also address the major reason for the growing demand for energy. That reason is overpopulation. However, no American politician has the guts to touch that topic. It is too closely tied to illegal immigration. When a faction in the Sierra Club tried to address that issue, the members of that faction were accused of being "racist".
I hope they will put it on new navigation maps. But how to update existing maps?
I would be a nightmare for a captain to meet such things in high seas. As far as navigation is concerned it is a new island.
In the very long-term (barring global catastrophes) humanity will have to start to settle the oceans, and this experiment will give us information as to how we might be able to do that in the far future.
I've always been fascinated if it might be practical to build a floating ocean settlement which could also submerge to a relatively shallow depth for relatively short periods to avoid the dangers of ocean storms.
Can only help them in one day becoming a citizen on the EU which I hear it is trying to do but have yet to be accepted.
One whale will die, whole project will be shot.
I missed the word "wind" in the summary and thought they had developed a current turbine. Ocean currents have incredible potential, but maintenance challenges make underwater turbines impractical today. But unlike wind and solar power, ocean currents and waves could actually displace fossil fuel as a primary source of energy.
marinelife greater threat than saltwater
HAhahaha. Ha ha ha. HA. No.
You may be thinking of Iceland.
All intents and purposes. Not intensive purposes.
But you are correct about overpopulation. There is no point reducing consumption per person by 10% if the population increases by 50%.
The scale of nearly every environmental problem we face is directly proportional to the size of the population. Politicians think that the slice of the cake that they will be left with after the profits, driven by those extra workers, have been disproportionately distributed, will be large enough for them to live a good life. They don't care what effect it has on those who will be less well off.
...dampen the motion from waves...
So the waves aren't wet enough yet? Norway has strange oceans.
On the other hand, I think for the first time "inertial dampeners" is the right term to use...
(Yes, to damp is a verb too. Heavily underused. As is "dampers")
I think someone mentioned this earlier, but the overall initial costs/building requirements will be the most expensive point in these turbines lifetime. Just like any major capital investment, the cost is static/ one time. After it's paid off in generating enough electricity at a given price, the long term results are more beneficial - yes this means less waste compared to nuclear reactors in service, also mitigating down potential hazards from previous known incidents and close calls. You can't ignore these measurable and discernible results and effects - they are part and parcel of the energy source. People need to remember that the long term and general picture of alternative energy sources is what needs to be considered - cost is irrelevant in that any new capital is expensive initially and that it gets paid off eventually through the function it serves (or functions).
If anyone needs me, I'll be in the Angry Dome.
Politicians think that the slice of the cake that they will be left with after the profits ...
We also have war to blame. Cultures and nations at war attempt to out-breed each other in order to produce more soldiers and laborers. The cultures that reproduce the most stamp out the others, and thus we evolve, becoming cultured to reproduce and exponentially more numerous until we stamp out all other life on the planet.
Hopefully someone puts the brakes on human reproduction before it goes that far. We've come a long way in the past couple of centuries, even though we grow more numerous; condoms are a good start.
For a real solution to population growth, check out VHEMT.org -- their argument is compelling.
to harvest the wave energy as well as the wind energy with something similar to this? I guess you could also slap some solar cells on it. =)
"It will be utility-size turbine, with a hub height of about 100 feet, capable of generating 2.3 megawatts of electricity."
No bleeping way will you get that many watts from a turbine that size. One of the numbers or units in the above sentence is wrong.
Virtually none of the 'alternative power' schemes work in a way that results in a net benefit to society. Hopefully this won't always be the case but right now the main way for an individual to profit is by collecting the subsidies or tax breaks.
The subsidies act to pay off various political players and reward sectors of the voting population. And except for in the minds of the most idealistic advocates, that's what they're intended to do.
You must mean what we call Greenland. Ice is what it is, unless you want to buy a timeshare, then it's Greenland.
We already have at least one tidal power plant operational here in Norway. We are also working on osmotic power.
Like our national oil company Statoil (state oil) that was mentioned above, our other national power company, Statkraft (state power), is innovating these kinds of projects:

Osmotic power installation

There are over a hundred thousand Minke whales just in the seas surrounding Norway, and we hunt less than a thousand a year. We conduct proper government controlled supervision of the hunt, and the product is used domestically.
It is a centuries old tradition and our sovereign national right to sustainably harvest our sea resources.
.
Ironically most people think hunting whales is illegal under the IWC moratorium, however Norway lodged formal objections, since the moratorium was not based on advice from the Scientific Committee, and we are thus legally exempt from the ban
.
Polar Bears are in fact a species Norway, the US and Canada are cooperating to defend and protect in our Arctic regions. Read more about the intitative here.
You talk about thirty years as if it's a long time--it's really, really not, if we talk about nuclear energy.
Let's find out the real cost of decommissioning a nuclear plant in 2046 and then discuss whether they are actually economically feasible.
To be, or not to be: isn't that quite logical, Slashdot Beta?
Oh I'm sorry were you one of the suckers that bought into wind power and are taking it out on me because I'm not as stupid as you? Moderation should not be anonymous so stupid assholes who simply disagree with you can push their agenda.
According to StatoilHydro "the floating structure consists of a steel jacket filled with ballast. This floating element will extend 100 metres beneath the surface and will be fastened to the seabed by three anchor piles".
There are plenty of details and videos about the project on their website:

If we disregard that terrestrial nuclear fuel is a finite resource, like petrol based fuel, there is also the risk/reward.
Already had "Three Mile Island" and "Chernobyl".
Lets see for solar: hm, perhaps some eyestrain from getting reflected sunlight in the eye?
Lets see for wind: being struck by a fan blade if one self-destructs?
And actually, I am quite the advocate of nuclear power: Fusion power. Big 'ol billions of years reliable nuclear fusion power plant running 100% output safely, and we orbit it constantly. Free for the harvesting, once we create enough solar panels, wind turbines, and such to capture its output.
I think the argument on financial costs is a fair one, but society also once decided that removing lead from gasoline was worth the higher cost, as well as putting catalytic converters on cars. Maybe not the greatest analogy, but seems to fit.
Uh, Linux geek since 1999.
Floating Wind Turbine?
It's probably that I just woke up and am dizzy enough for the fantastic to make sense, but. . .
I pictured a giant blimp with a windmill on it, tethered to Norway. And my only thought was, "Gosh, is that safe?"
My second thought when I realized I was mistaken was, "Aw, what a shame. That would have been cool."

It's already been done off of Scotland and off of Portugal by a Scottish company.
Any guest worker system is indistinguishable from indentured servitude.
... already wet.
...the turbine will have a specially designed control system that will seek to dampen the motion from waves.
For the love of God, people, oscillations are damped, not dampened!
