L'Islande cherche désormais à exploiter les effets favorables de ses volcans avec la vente d'énergie géothermique. [ho new/reuters]
L'Islande projette de construire le plus long câble électrique sous-marin au monde pour vendre son électricité d'origine volcanique à l'Europe, a indiqué lundi une responsable du plus grand groupe d'énergie islandais.
Après avoir paralysé les cieux européens avec d'épaisses volutes de cendres volcaniques l'an dernier, la grande île de l'Atlantique nord cherche désormais à exploiter les effets favorables de ses volcans en vendant à l'Europe de l'énergie géothermique tirée des eaux bouillantes de son sous-sol et de l'énergie hydrothermique de ses glaciers.
Pour ce faire, le groupe public d'énergie Landsvirkjun veut mettre en place un long câble électrique sous-marin afin de relier l'Islande à l'Europe. "Nous étudions entre autres le pays de destination. Les pays potentiels sont le Royaume-Uni, la Norvège, les Pays-Bas ou l'Allemagne", selon Ragna Sara Jonsdottir, porte-parole du groupe public d'énergie Landsvirkjun. Suivant sa destination finale, le câble mesurerait entre 1200 et 1900 kilomètres de long. "Ce serait le plus long câble sous-marin au monde", souligne la responsable.
Bientôt une décision
"Ce projet a commencé l'an dernier et la phase de recherches devrait être terminée d'ici la fin de cette année. Nous en saurons alors plus sur sa faisabilité", a déclaré la porte-parole, qui table sur une possible décision d'ici 4 ou 5 ans.
Le projet table sur un objectif d'exportation de 5 térawattheures (5 milliards de kilowattheures) par an, indique-elle. Cette production représente, au cours actuel de l'électricité en Europe, environ 250 à 320 millions d'euros d'exportations chaque année suivant les pays. Cela équivaut à la consommation de 1,25 million de foyers européens.
Remède à la crise
"L'idée est de répondre à la demande en Europe aux heures de pointe, ainsi qu'en partie en demande de base", explique Ragna Sara Jonsdottir, sans vouloir donner d'estimation du coût du projet. Landsvirkjun, qui appartient à l'Etat islandais, produit déjà environ 75% de l'électricité islandaise.
L'Islande, qui a traversé une grave crise économique après l'effondrement fin 2008 de ses banques jadis florissantes, cherche de nouvelles ressources pour relancer son économie, qui repose désormais principalement sur la pêche.

Personal comment:
It's funny because I was there in the same exhibition just two weeks ago, and I have the feeling that this is Philippe Rahm on the left of the third picture. I don't know though, I just speculate as I know that Gabriel is working with Philippe.
So, places and special interests connect (or sort of mediate the relation of) people through time... in an unconscious manner. A social software like Foursquare tries to connect people according to locations, through time. It's interesting but a major part seems to miss: the reason why you came somewhere, which is what "connects" the people (beside to have a drink, eat in an italian or chinese or to buy a product like what Foursquare seems to be about) and allows the specific place/event to eventually become a "psychic time machine", a "telepathic connector".

Personal comment:
I'm usually not a big fan of fractal visualizations, especially when they are used as visuals for techno parties... But this one is quite stunning and very close to what a fractal is: an evolving object with no defined scale, a very fascinating mathematical model. Big or small? A planet (Solaris ?) or a microbe? Living or dead?

Artist Dennis Oppenheim's " Whirlpool" project, from the summer of 1973, sought to create an artificial tornado on the bed of a dry desert lake in Southern California. It was intended as a "3/4 mile by 4 mile schemata of tornado," the above image explains, "traced in [the] sky using standard white smoke discharge from aircraft."
As the Telegraph describes it:
Employing one of [Oppenheim's] characteristic quasi-scientific methods, the piece was created by issuing radio instructions to an aircraft which discharged a liquid nitrogen vapor trail. The aircraft began by flying in revolutions measuring three quarters of a mile in diameter. Subsequently the pilot was instructed to repeat this manoeuver but, with each revolution, he was made to reduce the size of the diameter of the circle and lose height—and it is no mean feat controlling a plane according to these specifications. The operation had to be repeated three times before the desired whirlpool effect was achieved.
In a short story called "The Cloud-Sculptors of Coral D," J.G. Ballard envisions a tropical atoll where the residents have learned to "sculpt" clouds in the sky, listening to Wagner over loud speakers and using specially engineered gliders and flying techniques.
"Lifted on the shoulders of the air above the crown of Coral D," Ballard writes, "we would carve seahorses and unicorns, the portraits of presidents and film stars, lizards and exotic birds. As the crowd watched from their cars, a cool rain would fall on to the dusty roofs, weeping from the sculptured clouds as they sailed across the desert floor towards the sun."
They are part aesthetic object, part weather system.

Both of these came to mind this weekend when I read that artist Anthony McCall is planning to create something called "Column" in Liverpool, to coincide with the London 2012 Olympics. It will be "a spinning column of cloud a mile high," as Creative Review describes it, "visible across the North West region throughout the Olympic year."
Made of cloud and mist, this "swirling micro-climate" will be "created by gently rotating the water on the surface of the Mersey and then adding heat which will make it lift into the air like a water spout or dust devil."
We'll have to see how it actually works out, of course, but the idea that cities might soon deploy large-scale specialty weather-effects—that is, permanent climatological megastructures—instead of, say, Taj Mahals or Guggenheim Bilbaos as a way of differentiating themselves from their urban competition is a compelling one.
