Cleaning up the Seine with Physalia
Concerned about our rising population having serious water
supply issues in the not too distant future,
Lilypad floating city designer Vincent Callebaut has come up
with a floating amphibious garden that can clean our rivers as
it travels the waterways of Europe. His proposed "audacious,
avant-garde" Physalia project will be a self-sufficient, nomadic
research vessel which can also host aqua-focused exhibitions and
conferences.
Our survival depends on getting a regular supply of safe,
clean drinking water. According to figures provided by water.org
though, about one in eight people currently lack access to safe
water supplies. The United Nations says that nearly 4,000
children die every day due to dirty water or poor hygiene. Its
World Water Development Report says that by 2050, at least a
quarter of the world's population is likely to live in a country
affected by chronic or recurring shortages of fresh water.
With these stark facts in mind, Callebaut has designed
Physalia. He says that the vessel's structural design was
inspired by the physalia physalis (commonly known as
the jellyfish-like Portuguese man o' war), from the Greek for
bladder or water bubble. As the craft wanders the waterways
between the Danube and Volga, the Rhine and Guadalquivir, or the
Euphrates and Tiger, a hydraulic network in its
aluminum-covered, double hull will enable it to filter river
water through to the planted roof for some natural purification.
The Belgian-born architect says that, like his Lilypad
floating city concept, the self-cleaning vessel will have a
titanium dioxide photocatalyst covering on the "silver-plated
dress" which will help to further reduce water pollution. It's
also envisaged that Physalia will be able to drag itself out of
the water and operate on land too, although exactly how such a
feat is achieved is not discussed.
He also plans for Physalia to be completely self-sufficient,
producing more energy than it consumes (like the
Plus Energy housing projects). To this end, photovoltaic
panels in the roofing will harvest energy from the sun while
underwater turbines will convert energy from the flowing river.
The interior of the vessel will be divided into four themed
gardens representing the four elements. The main entrance will
open into a water garden where exhibitions can be hosted, and an
earth garden will also serve as a laboratory for international
aquatic research initiatives. Peeking below the surface of the
water will be the fire garden for dedicated exhibitions, and
where visitors can look out into the river environment through
underwater windows. Lastly, an amphitheater air garden will
incorporate meeting and conference space.
"It is an ecosystem reacting to its environment, a fragment
of living earth, inviting the fauna and the flora of the fluvial
biodiversity to come and make its nest in the city," says
Callebaut. It is aimed "at mixing people around the notion of
water respect, sharing in movement and dynamic balance," he
added. "After the Copenhagen conference, it is a project of
transeuropean leadership and a positive innovation of ecologic
resilience."
The architect doesn't go into any great detail on how all the
various technologies will be integrated into
Physalia, but concentrates more on how stunning it will
look. In that regard, we have to agree. As to whether such a
craft will ever leap from the drawing board and meander down
Europe's rivers as intended, cleaning them as it goes, we'll
have to wait and see ...
