Rinspeed sQuba, the water car




by Christophe » 04/03/08, 15:30

While some manufacturers "try" to make cars less and less dirty and the majority of people see their "purchasing power" drop ... others have fun making toys for billionaires ... but fortunately this one is 100% electric so "ZeroEmission" ... but the reality would rather be "ZeroDirectEmission" ... : Shock: : Shock:

How far are we going to descend? In any case this one does not dive more than 10 m ... : Mrgreen:

What would be the consequences of arrangements facilitating the use of amphibious vehicles. At a minimum, this would be the extension of traffic jams to waterways.

Not even, the heating of tires on the road also emits pollutants :D

ho there no, but if diving is like for 4x4, in town the all terrain is the sidewalks, for that there will be puddles?

the most polluting of all these machines that we ride in the water, it may not be the vehicle but the anti foulling they screw up on

http://fr.wikipedia.org/wiki/Antifouling
Active substances [edit]

Antifouling contains one or more molecules that are toxic to organisms that attach to the hulls of ships or submerged objects that you want to protect. To be lastingly effective, these toxins must be gradually released by the medium (binder) which forms the basis of this paint. Antifouling is therefore always polluting.

Ban on tributyltin [edit]

The highly effective tributyltin (TBT) was the most widely used marine biocide in the world, but this product, its degradation molecules and its metabolites have been shown to be seriously and lastingly polluting. TBT induces in particular in certain organisms a phenomenon of imposex (masculinization of female sexual organs in this case), at very low dilutions, lower than ng / L (in fresh or marine water). TBT residues, including tin, which persist for a long time in port sediments and on dredging sludge dumping sites and downstream after resuspension if necessary. For these reasons, in November 1999, an IMO resolution (A.895) was proposed, adopted on October 5, 2001, banning tin-based antifouling paints from January 1, 2003. Their presence on the hull of a ship will be banned from 2008.

Alternatives to tributyltin [edit]

Tin-free antifoulings often have a vinyl or acrylic medium (known to be less toxic), but labels and manufacturers omit to mention the nature and dosage of the biocides (insecticidal fungicides and / or herbicides) or additives they contain. Antifoulings are designed to be erodable over time over 1 or 2 years depending on the number of layers. We also tested and developed high tech materials; elastomeric polymers, new erodible polymers, silicone-based products, teflon or water-based self-polishing paints for better gliding on water, acoustic wave systems generated by electric discharges, etc. hoping to reduce the grip of organisms on the hull but which still lack feedback or dissemination.

According to the European Commission Project “Assessment of Antifouling Agents in Coastal Environment” (ACE), analyzes of the residues dropped into water by these paints give the following results:

- copper is the most used for its toxicity on phytoplankton and other organisms (Several centuries ago it was noticed that copper and brass submerged were not colonized by aquatic organisms). The paints contain it in the form of copper oxide, copper dioxide, copper thiocyanate, copper acrylate, copper flake powder, copper hydroxide ...

- Zinc is sometimes used in the form of zinc pyrithione.
- Cupronickel is sometimes used
- Rosin (Rosine or rosin) is often detected.

Among the biocides released into water, organochlorines have been found above all:

* dichlorophenyl dimethyl urea (diuron) which is one of the pesticides often detected in water, but also in rain (with in this case a supposed origin of agricultural origin)
* 2-methylthio-4-tert-butylamino-6-cyclopropylamino-s-triazine (Irgarol 1051®)
* 2,4,5,6-tetrachloroisophthalonitrile (chlorothalonil)
* 4,5 dichloro-2-n-octyl-4-isothiazolin-3-one (Seanine 211® - Kathon 5287), powerful phytotoxic
* dichlorofluoro methylthiodimethyl phenyl sulfamide (dichlofluanid)

In less quantity or less often, we also found

* 2-thiocyanomethylthio benzothiazole (TCMTB), very powerful and toxic fungicide
* 2,3,5,6-tetrachloro-4-sulfuronyl pyridine (TCMS pyridine)
* zinc dithio carbamate (zineb)
* arsenic trioxide, a powerful carcinogen, very toxic and subject to the Sévéso Directive;

These biocides are sometimes combined with each other and / or with copper to obtain synergistic effects, strengthen or broaden their spectrum of action.

Toxicity [edit]

Tributyltin is toxic to humans. It is prohibited, but relatively persistent. The tin that composes it is not biodegradable. The solvents in most antifoulings are also toxic, and the active molecules in the new antifoulings are neither harmless nor sometimes less toxic than tributyltin.

Their toxicity for humans is:

- direct following the inhalation of particles, for example when using a paint gun without a suitable mask, or when sanding the antifouling layer of a hull, or by passing through the skin following projections or contact with paint, or more rarely via accidental ingestion, or for children who wear paint chips in their mouths (phenomenon known as "Pica").
- indirect, by ingestion of filtering shells such as mussels, oysters, cockles, etc. or other seafood (eg sea urchins) or fish that have grown downstream of careening sites (painting or stripping ship hulls, large or small) or near submerged wrecks. Regular consumption of contaminated seafood is likely to induce acute or chronic illnesses linked to heavy metals. It is common for fairing waste to be cleaned in a karcher and pushed into the water, or simply left on the spot, although it meets the legal definition of toxic waste.
- Allergic phenomena may also exist. The toxicity of metals varies according to the history and genetics of individuals.

Ecotoxicity [edit]
toxic antifouling scales, left on the ground, in a flood zone, during successive fairings

For several decades, antifouling paints have contained stannic derivatives (ie containing tin, such as TBT, tribultyltin), whose toxic (and hormonal disruptive) effects on the marine environment have been significant, to the point of decimating natural populations of shellfish and disrupt the reproduction of many species. The use of these substances is now prohibited under IMO conventions. The new antifoulings are less toxic, but remain so. They are part of the Biocides family. This is why their application with a paint spray gun must be done with a mask. The brush application must be done with gloves and an appropriate suit and in ventilated space.
The holds and maintenance sites of ship hulls should be isolated from the aquatic environment, and waste treated as toxic and dangerous waste (they must not be buried in the ground, nor incinerated).
Carcasses of ships submerged to make artificial reefs should always be rid of their polluting elements (copper, brass, lead, machines, fuel fats, paints ...) and their antifouling should be ideally stripped. Analyzes made on mussels growing around wrecks have shown that they accumulate heavy metals lost in the water, in their flesh, but also in their shells. The metals contained in paints and antifoulings are neither biodegradable nor degradable.
It seems plausible that the reduction in crab and crustacean populations observed in all ports in recent decades is partly due to antifouling. Locally, for example in the presence of an earth connection put into the sea on industrial arc welding sites, electric field phenomena (anode / cathode) could perhaps reinforce the passage of metals in water, this which would further reinforce the presence of toxic in the sediments near the shipyards.
The ecotoxicology of biocides in the marine environment is a young science with few resources, but some indications suggest that in closed ports, by killing organic matter, antifouling could contribute to certain phenomena of dystrophization and proliferation of species undesirable. The phyto- and zooplankton species most sensitive to biocides disappear in favor of unwanted or toxic algae (eg dinophysis), which could increase the risk of TIAC (food poisoning), in particular diarrhea induced by consumption of bivalves polluted by this microalga.

Some biocides and other pollutants can accumulate in the biofilm that forms on the surface of calm waters and be "exported" with spray to the coast and inland areas during storms, to the point of affecting or even killing the most fragile plants in the coastal strip. It is also plausible that certain organisms may develop resistance to certain biocides.

Mwarf! All that is not worth a good old Alberich coating !!

For those who don't understand my delirium: https://www.econologie.com/pa/annonces/c ... -4-47.html
http://www.uboataces.com/sonar-coating.shtml
http://www.uboat.net/forums/read.php?20 ... 42,quote=1

ALBERICH. This was a textured synthetic rubber called OPPANOL. The idea behind this 4MM thick rubber was to cover the entire u-boat in this textured rubber. In reality this OPPANAL only reduced the sonar pulse by about 15 when the boat was at periscope depth.Absorption varied with depth, temp and salinity. The big problem with this system was that of addhesion. There was just no glue at the time that would keep the rubber panels in place. Over time wave action etc. made the rubber panels come lose and actually create more noise than a boat that did not have the coating. It was also found to decrease the speed of the boat by about 11/2 knots.


Well, it's not just econology in my life ... : Mrgreen:
