Floating water sewage and treatement

http://www.cmdr.ch/ocean98/fwtp.htm




A CLEAR SOLUTION

There is a system that solves a problem of coastal wastewater pollution. It can process municipal sewage from medium to large cities situated in coastal areas where local topography often limits the available sites for land based treatment facilities. In the Czech Republic a floating waste water treatment plant was developed as a cost effective solution for processing municipal sewage from medium to large cities situated in coastal areas where local topography often limits the available sites for land based treatment facilities. It can be hooked to any existing canal system in a matter of days and starting to treat the sewage that otherwise is dumped in the costal waters. It offers the possibility to recycle up to 88% of the treated wastewater and return it to use in the community. In communities facing water shortages, this capability may be a key factor in decision making process.

Deux pêcheurs birmans rescapés après 25 jours dans la mer : Le Point


Deux pêcheurs birmans ont survécu pendant près d'un mois dans des eaux infestées de requins en flottant dans un grand réfrigérateur après le naufrage de leur bateau, ont déclaré leurs sauveteurs.
Les deux hommes, âgés d'une vingtaine d'années, étaient employés avec 18 autres marins sur un bateau de pêche thaïlandais qui a chaviré le 23 décembre au large de la côte nord de l'Australie, a précisé Tracey Jiggins, porte-parole de l'autorité australienne de sûreté maritime.
"Ils n'avaient pas d'équipement de survie, pas de balise, pas de moyen de communiquer et ils ont dérivé pendant 25 jours", a-t-elle ajouté. Le réfrigérateur, utilisé par les bateaux de pêche, avait la "taille d'un bureau".
"C'est stupéfiant qu'ils aient été repérés dans une telle masse d'eau." C'est un avion de la garde-côte australienne qui a vu les deux hommes samedi. Ils ont été hélitreuillés et hospitalisés sur l'île de Thursday Island.
"Dès qu'ils sont montés, ils ont bu chacun deux litres d'eau en quelques secondes", a raconté le pilote d'hélicoptère à la télévision.
Les deux rescapés étaient affamés et déshydratés mais leur état n'inspire pas d'inquiétude et ils devraient sortir rapidement de l'hôpital.
Ils seront alors interrogés par les autorités qui se demandent comment ils ont survécu et ce qu'ils ont mangé et bu pendant près d'un mois.
Tracey Jiggins a déclaré que les autres marins à bord avaient certainement péri et qu'aucune recherche ne serait entreprise.
"Ce qu'ils nous ont dit, c'est qu'ils ont vu les autres membres d'équipage dans l'eau, sans gilet de sauvetage. Nous pensons qu'il est impossible de survivre dans l'eau pendant 25 jours."

Condenser

< Peter Von Bartheld >

Salty water can be condensed to get fresh water. Sea water is being pumped up into the lower compartment in small quantities by a simple pump powered by the waves. The black isolated plate heats up the water through solar energy, the water vaporises, moves trough holes into the second compartment were it condenses against the transparent outer layer. It drips down and is being collected at the bottom of the second compartment.

Aquanaut adventure, urine and drums

[via newscientist.com]

Well, this is not quite "open" nor "sailing", but it has a lot of cool stuff inside!

Aquanaut adventure

Imagine spending 13 days underwater with nothing for company except some urine-loving algae and a drum kit. It hardly sounds like a great holiday, but it was a dream project for Lloyd Godson, an Australian marine biologist who wanted to create and live inside his own "bio-regenerative microcosm".

Godson has spent the last couple of weeks living inside a metal box measuring 3m x 2m x 2m some 5m below the surface of a quarry lake near Albury in south-eastern Australia . He won £20,000 funding for his BioSUB project through a competition called "Live Your Dream", sponsored by the magazine Australian Geographic.

The BioSUB contained various systems to keep Godson alive and well. These included an algae biocoil to produce breathable oxygen and absorb exhaled carbon dioxide when soaked in his own urine.

Another system, called Air2Water absorbed moisture from the air to produce drinking water. And Solar panels back on the shore and an exercise bike inside the box produced electricity for light and a waterproof laptop. And, each day, meals were delivered by scuba divers, although the website mentions a plan to eat some of the algae too. Yummmm.

Apparently, Godson also helped stave off boredom by playing the drums (without fear of upsetting any neighbours). And he produced a surprisingly catchy song to celebrate his mission, which you can see him performing here. I really admire Godson's spirit of adventure. Hopefully it won't be long before we hear about another one of his unconventional research projects.

Le 26 mai 1952, il part de Monaco avec un coéquipier, l’Anglais Jack Palmer, pour une traversée de la Méditerranée, de Monaco jusqu’aux Baléares sur un canot pneumatique baptisé l’Hérétique, gréé avec une voile d’optimiste et bâché. « J’étais un hérétique pour plusieurs raisons. Nous allions essayer de nous rendre, avec un engin réputé non navigable, à un point déterminé à l’avance. Cette première hérésie touchait directement les techniciens de la mer et de la navigation. Plusieurs spécialistes nous avaient, en effet, assuré que nous ne dépasserions pas les îles d’Hyères. Plus grave était le fait que je m’attaquais à la croyance générale selon laquelle on ne peut pas vivre exclusivement sur les ressources de la mer et que l’eau salée n’est pas potable. Enfin, pour reprendre un article paru sur nous dans un journal “sérieux”, “alors que des marins d’expérience ne se croient jamais suffisamment à l’abri des fureurs de la mer, des vents et des courants, un novice n’hésite pas à confier sa vie et celle de son compagnon à une simple coquille de noix, qui n’était même pas vérifiée par un inspecteur de la navigation”. Aussi, avais-je baptisé notre canot l’Hérétique ».

Map of hidden water

map of hidden waters

They are one of the world's greatest and most precious natural resources, yet are entirely hidden. Now, for the first time, a high-resolution fresh water world map (8mb pdf) shows where underground aquifers store vast amounts of water.

The map of "blue gold" is the result of nearly a decade of sometimes difficult talks between neighbouring governments, mediated by UNESCO. The hope is that it will help pave the way to an international law to govern how water is shared around the world.

Acali Expedition

lexpdition_acali

Le 13 mai 1973 (était-ce un vendredi?), 5 hommes et 6 femmes qui ne se connaissaient ni d'Eve ni d'Adam, embarquaient pour une expérience humaine unique de 101 jours en mer sur le radeau "Acali" (du nom d'une province mexicaine). Une coque de noix dessinée par l'architecte britannique Colin Mudie, reconstructeur, entre autres, de l'Argo amarré à Gênes.

A lire ou à relire, "L'expédition Acali" par l'anthropologue mexicain Santiago Genovès, le premier radeau moderne à ralier l'Afrique au Mexique. Je n'ai trouvé aucun site internet y faisant référence, alors bonne lecture. Santiago Genovès a participé aux expéditions Ra 1 et Ra 2 de Thor Heyerdahl, navigateur, anthropologue et archéologue ayant traversé l'Atlantique sur des radeaux en papyrus.

Extrait: "Entre les chercheurs qui restèrent à terre et nous qui prîmes la mer se produisirent des heurts; il y eut de l'envie, de la jalousie, de la peur. Dans le radeau et loin du radeau. Dans la science et hors de la science. C'est de tout cela qu'il s'agit dans le projet Acali".

20 ans après l' "Acali", l'expédition "Hsu-Fu" reliait la Chine aux côtes de l'Amérique en jonque traditionnelle de bambou. [source : http://www.leblognautique.com/livres/index.html]

Amphibious Architecture

Amphibious Architecture : The East and the Bronx Rivers in New York are home to a new installation project that offers a "looking glass" into the marine ecosystems of the rivers. The Amphibious Architecture project is a way of connecting humans with the watery world upon which we depend, through an amazing lighting display that reflects the incoming information of attached sensors. As the sensors pick up data on water quality, the presence of fish, and human interest in the water system, the lights tell the story of the interactions and feedback loops are created. An interesting, techy way for fish and people to interact, right? But it doesn't stop there - also thrown into the mix is the ability of humans to text message fish. Yes, text message...and get a response.


Video by Chris Woebken

It sounds over the top, but actually it's a very intriguing idea: People can text message the fish, and receive back real-time info about the river system. Text fish a "how are you," and you'll get a response. Pretty cool.



Distinctly moving away from the pervasive 'do-not-disturb' approach to urban environmentalism, the project encourages curiosity and engagement. Treating the river water as a reflective surface to mirror our own homo-image and architecture, establishing a two-way interface between the terrestrial and the aquatic. The project thus creates a dynamic and captivating layer of light above the surface of the river, making visible the invisible through real-time mapping of the new ecology of people, marine life, buildings, and public space.

Amphibious Architecture is a project by xClinic Environmental Health Clinic at New York University and the Living Architecture Lab at Columbia Graduate School of Architecture, Planning and Preservation.
