SNAILS SHELL SYSTEM
SNAIL SHELL SYSTEM 2001. Music by Anders Remmer.
Introduction:
The SNAIL SHELL SYSTEM is a low cost system that enables persons to
move around, change their whereabouts and live in various environments.
One unit supplies space for one person. It is mobile both on land and water.
One person can move it slowly, either by pushing it like a wheel, walking
inside it or on top of it.
On water it can be rowed, moved by a kite or hooked up to a vessel, for
example, a ferry. The unit rests on one flat side and can be anchored in
lakes, rivers, harbours or at sea. On land, it can be placed in city spaces,
fields, forests etc.
The SNAIL SHELL SYSTEM takes up very little space and can easily be placed
in a discreet way. It can be buried in the ground, exposing only the entrance.
It can also function as a comfortable space inside existing buildings.
Several units can meet up and form temporary communities.
The unit can be hooked up onto existing infrastructure like telecommunication
lines and electricity cables (for example, by connecting it to street lamps).
If special devices are added, the unit can supply its own energy.
The SNAIL SHELL SYSTEM can also be used for transporting different items
and it can provide protection for persons when they participate in situations
like demonstrations.
Construction:
The SNAIL SHELL SYSTEM is constructed from a cylindrical polyethylene tank.
The tank was chosen for its non-toxic material, low weight and its ability
to roll. A spherical tank would also work, but standard tanks of that shape
are rare and expensive. Various devices are attached to the tank, adding
different functions. Caterpillar tracks of rubber are fixed to rubber knobs
on the tank. They protect the tank during transportation, add friction and
make it easier to steer the unit. They also function as protective fenders
when the SNAIL SHELL SYSTEM is moored. The caterpillar tracks can be removed.
On one of the flat sides, a small and a larger hole perforate the unit,
and function as an air intake and entrance respectively. A removable lid
covers the entrance, which when left half-open also supplies air, while
keeping rain out. Whenever a person is inside the unit, it must be left
either halfway or fully open. The air intake provides a constant supply
of fresh air.
Three eyebolts, fixed to the surface, function as points to which the unit
can be moored on water or whenever it is exposed to strong wind. This can
be done by using the rope that is coiled up around the air intake. A paddle
as well as a hand bilge pump is attached to the unit. The bilge pump can
be used for supplying fresh water or for removing water or other liquid.
It also functions as a vacuum cleaner. The bottom is covered by a foam sheet
that insulates the unit and also functions as a mattress.
Fixed to this is a box which contains equipment for cooking, a container
for drinking water, a torch, a sponge for removal of condensed water, and
a tube which can be fixed to the bilge pump. When the box is emptied of
these items, plastic bags can be fixed to the box, which then functions
as a toilet seat. Because the materials are not fireproof, cooking must
be done outside the unit. Elastic strings at the bottom hold the foam mattress
in place and can also be used to secure the box as well as other items during
transportation of the SNAIL SHELL SYSTEM.
Extensions:
All kinds of extensions can easily be made to the system. More equipment
can be made to fit inside as well as outside the unit. Insulating material
can be strapped onto the surface (or insulating material like snow, leaves
or earth can be piled up around it).
Devices like dynamos, solar panels, wind mills, etc., can be added so the
unit supplies its own energy.
Links to combine several units can be attached. Polyethylene can not be
glued to other material so all extensions must be fastened e.g. by lashing
or screwing. Care must be taken not to damage the plastic or perforate it
in ways that could cause leaks.
