Fukushima Floating Offshore Wind Turbine Starts Generating Power
mdsolar writes in with news about a new wind-energy project off the coast of Fukushima. "A project to harness the power of the wind about 20 kilometers (12 miles) off the coast of Fukushima, site of the March 2011 nuclear disaster, began generating power on an operational basis today. The project, funded by the government and led by Marubeni Corp. (8002), is a symbol of Japan's ambition to commercialize the unproven technology of floating offshore wind power and its plan to turn quake-ravaged Fukushima into a clean energy hub. 'Fukushima is making a stride toward the future step by step,' Yuhei Sato, governor of Fukushima, said today at a ceremony in Fukushima marking the project's initiation. 'Floating offshore wind is a symbol of such a future.'"
Sounds like there's an extra step involved.
Nothing is happening at Fukushima Nuclear Plant. Wind power is great and all, but NOTHING has happened. Even the leak is minute in comparison to the damage done by the tsunami. Solar, Wind, Nuclear Fission and Fusion, that is the future gentlemen.

Wouldn't the big-ass-tsunami they had be even more notable.. for an offshore... anything?
Offshore wind is hardly unproven. Wind turbines in general are well established and becoming a mature technology. The off shore part is also fairly well developed around the world and really just needs more cost reduction. There is no chance of it not working or anything like that, and it already economically viable.
Japan has vast offshore wind resources, with constant power available all year round.

So... Japan set up a giant radioactive fan offshore and the Philippines gets hit by an incredibly powerful hurricane...
That was relatively fast. In other countries, they'd still be debating whether such a construction should even be undertaken...
The Bloomberg article doesn't really go into the practical aspects of this, like expected average power output, mean time before turbine maintenance in a highly corrosive environment, or safety during adverse weather. Anyone got more info?
This is completely unrelated and random and not a shot at anything but um...how much power does it generate from radioactive wind? Is it more or less?
Wind power: producing as much power as six nuclear reactors from just one turbine!

How about an article with a picture of the thing. You know how us Americans don't like stories without pictures. http://www.scientificamerican.com/article.cfm?id=japans-offshore-wind-power-rises-within-sight-of-fukushima-nuclear-plant
my ass feels so relaxed and empty
...I know, I know...tsunamis and typhoons don't cause much damage 12 miles from shore. But still, doesn't this seem like a somewhat poor location for a floating wind turbine? It's not anchored to the seafloor, which means that typhoons and storms could push it close to shore, and we've seen the kind of debris that can be produced by a tsunami.
Japan may not have a lot of power options, but it seems like this might not be the best choice...
Great warrior...hrmph! Wars not make one great.
I'm sure the first thing they did was throw the manual over their shoulder...

If my account is set to Canada, I should only see "A project to harness the power of the wind about 20 kilometers off the coast of Fukushima".
If you wish to see "A project to harness the power of the wind about 12 miles off the coast of Fukushima", which frankly is a system designed for children, Slashdot should convert it for you according to your account settings.
Isn't there a Web standard that should do all of this automatically anyway? If there isn't, why the fuck not? Discuss below.

I believe we should be reducing our carbon output, but wind turbines are a sick joke. Here in the UK we're paying over double the price per unit of electricity than they're paying in nuclear heavy France, and that's entirely thanks to the green levies on energy. If the government were using this money to build nuclear power plants I would find it acceptable, but they're pissing it down the drain building wind farms.
Why are we bankrupting ourselves by spending vast amounts of money on inefficient methods of power generation? Why are we risking blackouts by relying on an entirely inconsistent approach that puts us at the mercy of nature? Why are we rejecting scientific advancement and falling back to ineffective technology from the middle ages?
The whole thing angers me so much that I'm tempted to start burning things purely out of spite.
Bloomberg calls wind power "unproven technology". What are you, fox noise?
For those who seek perfection there can be no rest on this side of the grave.
It's a giant fan blowing all the radiation to the West Coast.
Oh, that's nice. Add another *five hundred* turbines and you'll come close to matching what was lost when the nuke plant shut down. On a windy day.
The public tends to vastly underestimate the energy output of wind turbines. I'm not arguing that wind is pointless -- far from it! But two wind turbines is just an empty symbolic gesture. Two thousand wind turbines ... now you're talking.
You know, I do believe the US developed these "Floating Offshore Platforms" that generate power some time ago, we just decided to put nuclear reactors and F-16's on ours.
Why an international army hasn't landed at Fuckedupshima to take over the plant from the obviously incompetent corporation is beyond me.

Maine put in a floating wind turbine this summer. http://www.huffingtonpost.com/2013/06/04/us-floating-wind-turbine-maine_n_3380208.html but Maine's governor recently wrecked an expansion of offshore wind there as well. http://www.huffingtonpost.com/2013/10/15/maine-offshore-wind-project_n_4101271.html
Either I am not seeing it or it's not mentioned, couldn't a "floating" wind farm also generate hydropower from the water passing by too?
And also miss the entire name of the place and the news about it: The nuclear power plant has gone unexpectedly offline.
Unless you're trying to claim that they PLANNED for the power station to go critical, your statement:
"Don't forget that the reactors were able to provide that power reliably and predictably"
Is completely asinine.
According to TFA, the initial turbine has a 2 MW capacity. Offshore wind has about a 0.3-0.4 capacity factor. Nuclear has a 0.9 capacity factor. So to replace the 4696 MW the Fukushima nuclear plant could generate, you'd need (4696*0.9) / (2*0.35) = 6038 of these 2 MW turbines. Even if you go with the larger 7 MW turbines they're planning as a follow-up, you'd need 1725 of those.
Considering they've set aside $222 million to build and operate these three turbines for 5 years, a full replacement for the nuclear plant's generating capacity would cost $167.5 billion. Realistically I expect that price would come down if they did roll it out on that scale. But even land-based wind turbines are about $1.8 million per MW of capacity. So the 12000 MW of turbines you'd need to replace the Fukushima nuclear plant would have a baseline cost of $22 billion before you added the floating platforms and adapted them to survive in a saltwater environment and lay down power cables to bring the electricity back to shore.
I wish we would hurry up and crack cheap hot-fusion powerplants. Cheap, safe, abundant, and limitless electricity would be a key enabling technology to carry us forward and away from fossil fuels. So many Big Problems could be solved with copious amounts of environment-friendly electricity. It would be the saviour of the human race ( the question is, do we deserve to be saved?)
That could be done, sure. You would need to allow free rotation of the base of both the air and water blades relative to some shared flotation base. This way, the vaned blades could turn into currents without interrupting each other.
It would be best if it were fixed to a tower, to offer the most resistance to currents. Otherwise the wind and water currents might fight against keeping a tether taut.
Even better than vaned blades, you could use a vertical-axis helical turbine for the wind, and you could use the Cetus blade [Cetus Energy: http://cetusenergy.com.au/Technology/TheCetusTechnology/tabid/96/Default.aspx ] in the water which would probably generate power no matter which way the current was passing.
The platform's bouyancy would just need to counter the force of the combined masses and gravity.
I suppose a design like that could be tethered and would often be found in some optimal location, systematic to the two different currents. But, this design would also probably be very expensive to license, as most of the more efficient vertical axis turbines are patented (and the Cetus blade certainly is.)
So it might be cheaper and might deliver substantially more power output if it were a stationary tower.

thousands of tons of contaminated nuke water leaked, that got to help A LOT.
This sounds like a Vesta WindFloat 2MW turbine. Is this really a Mitsubishi product?
Fukushima has an advantage as a site: Since it's depopulated due to the radiation hazard, there's nobody to complain about how "those ugly windmills are ruining my view".

Do you really think all those people moved out as some sort of green propaganda instead of as a response to a real danger?
Your post reveals more about your state of mind than anything on the ground in Japan.
Only 12521 more wind turbines more to go and you will be able to equal the reactors output.

Dr. Mita addresses the need of blood examination among children in Tokyo
11 November 2013 World Network for Saving Children from Radiation
Dr. Mita, Mita Clinic in Tokyo: Our patients mostly come from Tokyo. Reference value of white blood cells for healthy children is 4000, but it has shifted to 2500. It is lower than the threshold value of 3000. We think these points at a serious problem.
And when these children spend some time in West Japan, they get better. But our real hope is to have not just children but also adults move away from Tokyo. The adult conditions are definitely different compared to how it was before the nuclear accident.
With elderly people, it takes more time for asthma to heal. The medication doesn’t seem to work. We also see more patients with diseases that had been rare before; for example, polymyalgia rheumatica. Before the nuclear accident, we had one or less patient per year. Now, we treat more than 10 patients at the same time.

I hope no one trips over the extension cord to shore.

Examining the coast of Japan, water depth, I expect the only being capable of this is Godzilla or a Kaiju.
I'm curious how this thing would withstand a typhoon.
