An Unexpected Benefit of Nuclear Energy

Although it may be helpful in reducing global warming, the Finns have now shown that nuclear power can provide an additional benefit by producing local warming. reports:
In the shadow of the Olkiluoto nuclear power station in western Finland, Latvian zilga grapes will this year produce about 80 bottles of red wine, said Jukka Huttunen, who cultivates the vineyard next to the facility's two reactors.

The vines are nourished by the warm water from the plant's cooling system, allowing grapes to thrive in a country that's on the same latitude as Alaska. Teollisuuden Voima Oy, the Finnish utility that owns the plant, started making wine as an experiment into uses for excess heat generated by nuclear energy. The company is now expanding production, said Huttunen.

Sea water used in the cooling process warms up by 13 degrees Celsius (55 degrees Fahrenheit) and is channeled through the 1,000 square-meter (10,764 square-feet) vineyard on its way back to the Gulf of Bothia. That helps kick-start the growing season three months earlier than usual and allows vines to thrive in normally hostile Finnish soil, according to [Olli-Pekka] Luhta [, the environmental manager for Olkiluoto].
If the Finns can do this with reactors of Russian design, just think of the possibilities when they start operating their French-designed EPR.

I would'nt mind betting that some extreme anti-nuclear "environmentalists" would argue that the local warming constitutes an unacceptable environmental impact. I would disagree of course. Every form of electrical generation has environmental impacts, and the global and local community has to come to a decision about which impacts it can live with and which it can't. I can live with localized warming and deep geologic storage of used fuel or waste products from reprocessing used fuel better than I can live with ash, soot and CO2 - unless the local warming drives a plant or animal species to extinction.

I don't have a problem with localized warming when it is being put to a good use such as this. Yes, ecosystems could be severely damaged by a 13C rise in temperature, but this seems to mitigate that problem. After running through the vineyard and making use of that heat, what is the temperature at which it returns to the sea?

bad conversion between Celcius and Farenheit.

You are using the correct formula
oF= 32+ 1.8XoC .

Although 13oC is 55oF in absolute terms...when you are talking about a temperature increase, a delta, the constant from the equation, 32, falls out. So a rise of 13oC is actually 13*1.8= 23.4 oF rise in temperature.

A Design Team Pictures the Future of Nuclear Energy

For more than 100 years, the shape and location of human settlements has been defined in large part by energy and water. Cities grew up near natural resources like hydropower, and near water for agricultural, industrial and household use.

So what would the world look like with a new generation of small nuclear reactors that could provide abundant, clean energy for electricity, water pumping and desalination and industrial processes?

Hard to say with precision, but Third Way, the non-partisan think tank, asked the design team at the Washington, D.C. office of Gensler & Associates, an architecture and interior design firm that specializes in sustainable projects like a complex that houses the NFL’s Dallas Cowboys. The talented designers saw a blooming desert and a cozy arctic village, an old urban mill re-purposed as an energy producer, a data center that integrates solar panels on its sprawling flat roofs, a naval base and a humming transit hub.

In the converted mill, high temperat…

Sneak Peek

There's an invisible force powering and propelling our way of life.
It's all around us. You can't feel it. Smell it. Or taste it.
But it's there all the same. And if you look close enough, you can see all the amazing and wondrous things it does.
It not only powers our cities and towns.
And all the high-tech things we love.
It gives us the power to invent.
To explore.
To discover.
To create advanced technologies.
This invisible force creates jobs out of thin air.
It adds billions to our economy.
It's on even when we're not.
And stays on no matter what Mother Nature throws at it.
This invisible force takes us to the outer reaches of outer space.
And to the very depths of our oceans.
It brings us together. And it makes us better.
And most importantly, it has the power to do all this in our lifetime while barely leaving a trace.
Some people might say it's kind of unbelievable.
They wonder, what is this new power that does all these extraordinary things?

Seeing the Light on Nuclear Energy

If you think that there is plenty of electricity, that the air is clean enough and that nuclear power is a just one among many options for meeting human needs, then you are probably over-focused on the United States or Western Europe. Even then, you’d be wrong.

That’s the idea at the heart of a new book, “Seeing the Light: The Case for Nuclear Power in the 21st Century,” by Scott L. Montgomery, a geoscientist and energy expert, and Thomas Graham Jr., a retired ambassador and arms control expert.

Billions of people live in energy poverty, they write, and even those who don’t, those who live in places where there is always an electric outlet or a light switch handy, we need to unmake the last 200 years of energy history, and move to non-carbon sources. Energy is integral to our lives but the authors cite a World Health Organization estimate that more than 6.5 million people die each year from air pollution.  In addition, they say, the global climate is heading for ruinous instability.
