The drought
affecting
lifestyle change is on the march. The solution is water and Sydney
Water is under enormous pressure to deliver. The solution is a
desalination plant at Kurnell. My idea is to make it portable
as on a boat so it becomes a more valuable resource later. Any green
benefits are a plus.
As
Climate Change moves across the
planet, the rain misses
traditional catchment targets. The job requires a portable desalination
plant.
Suggesting a portable desalination plant requires a plan.
The
Desal Watercraft
Carrier is, but is not limited to, a large scale 3 or more tiered portable floating collector of wind
wave tide and solar energies with battery and reverse osmosis desalination plant on-board. Gathering power, storing power and making
water for
cities.
One
day it might be able to roam
the seas searching for the best possible weather conditions gathering
the full potential, but typically it would be moored off the coast
exchanging
eco energy for fresh water, re-charging, and pumping fresh water back
to the coast
through a
pipe. [ Desal

MEDIA
RELEASE - March 27 2007
Sustainable Energy
And Desalination
On Vessel
Eco-friendly
desalination plant set to solve water woes
.
An Australian company, Seadov Pty Ltd
today announced an information release of a unique world first
renewable energy desalination technology which addresses coastal
potable water shortages.
The
technology comes
with impeccable "green" credentials and is, ironically, to be initially
based on the use of converted oil tankers and is to be made available
to water authorities for no capital outlay.
This
"Green
Marine"
Seadov (Sustainable Energy And Desalination On Vessel) technology can
cost effectively generate enough potable water to end water
restrictions in most coastal cities of the world.
Conceived
by
a leading
Australian marine management consultant in conjunction with a renewable
energy expert with a PhD in wind turbine design and a Gold Coast
technology developer, this technology is poised to offer its unique
solution to a water thirsty world.
Seadov
is
the only
desalination plant using an innovative combination of wave, tidal,
solar and wind energy devices which are integrated into an off-shore
vessel to power an on-board reverse osmosis desalination system and its
associated "ship-to-shore" pipeline pumping system.
Being
located off-shore,
no large intake tunnels are required for the sea water and treated
water is pumped to shore under pressure through sea bed pipelines.

HYDROKINETIC UNDERWATER TURBINES
The
Hydrokinetic Underwater Turbine is not like a wind generator. First
generation adopted aeroplane propeller type design. 2nd generation
depart into more adventurous and creative designs improving efficiency
by a factor of 2 and possibly 4.

Barge Mounted Desalination Plant
Low Temperature Thermal Desalination (LTTD)
A
Barge Mounted
Desalination Plant of Capacity 1000 m3/day was successfully
commissioned off the coast of Chennai during April 2007. The plant runs
on the principle of Low Temperature Thermal Desalination (LTTD) that
involves evaporating warm surface seawater (at about 29C) in a Flash
Chamber maintained under Vacuum (at about 25 mbar) and consequently
liquefying the resulting vapour in a Condenser. The coolant water for
the condenser is drawn using the thermal gradient available in the
ocean, namely using the feature of reduction of ocean water temperature
with an increase in depth. A 500m long pipe is deployed in the ocean to
draw the cold water (at about 10C) from a depth of about 450m. The
entire plant and mooring was designed by NIOT and manufactured and
installed indigenously.
LTTD
TECHNOLOGY
By flash evaporation, sea surface water (27-30C) under low pressure is
converted into vapour which is then condensed into potable water with
cold sea water (9-12C) drawn from a depth of 500 m. This technology can
also be used to produce potable water using temperature differential of
surface sea water and the water discharge from waste heat recovery unit
of power plants located near sea shore.

Solar
Sailor proposes to ship water from Tasmania to Sydney in
Solar-Wind-Electric SUPERTANKERS!
SOLAR
SAILOR WATER SUPERTANKERS
"Get
on board a
cleaner world"
Former
Prime Minister Bob Hawke urges Solar Sailor Aquatankers
http://www.smh.com.au/news/national/on-the-horizon-solarpowered-tankers-to-slake-sydneys-thirst/2007/01/16/1168709754693.html
Sydney-based
sustainable
technology firm, Solar Sailor Holdings Ltd propose to build a fleet of
solar-powered
tankers which could deliver water from the Kimberley to Perth for less
than
$1 a kilolitre.
This
compares
favourably with the
Water
Corporation's estimate of $1.11 a kilolitre for water from its proposed
desalination plant.
The
former prime minister said the supertankers were environmentally
friendly and economically viable. "Theoretically there's no reason
why this could not be used in Sydney - the concept of bringing the
water
is very straightforward," Mr Hawke said.
