Another closet idea by John Zulaikha
1-16 Nov 2005

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.

SUSTAINABLE  ENERGY AND DESALINATION ON VESSEL

MEDIA RELEASE - March 27 2007
Sustainable Energy And Desalination On Vessel

Eco-friendly desalination plant set to solve water woes

AUSTRALIAN COMPANY SEADOV
RENEWABLE ENERGY DESALINATION.

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.

NIOT successfully commissioned 1000 m3/day LTTD Desalination.
NIOT LTTD Desalination

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

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.
