Another closet idea by John Zulaikha

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.
Sustainability at this stage costs a little extra but is considered cheaper in the long environmental run.
The management of waste in a renewable cycle is less – there is likely to be little waste because that’s what renewable is, the fuel re-news itself. The sun is the best example, we can use it over again and again.
It is a direct saving not to have waste to clean up or fuel to find.
SYNERGY ENERGY RECOVERY
The massive energy and cost figures is not my expertise but the common thread of new “component parts” is efficiently utilising the waste energy at each stage. The breaking action in an electric car is stored in a battery and re-used to accelerate. The up and down action on the waves creates a vacuum in the air tight pressure piston pump.
Sourcing energy from all 4 directions at once, solar wind wave and tide – is a broader energy spectrum. Is manouverable and can seek best position much as any sailing ship turns to the wind. Only a sea worthy craft can experience all 4, tide wave wind and solar exposures. Managing waste energy by improving efficiency with clever ideas.
The efficiency of a floating desalination plant requires the other energy hungry components to compliment the 97% efficient PX Pressure Exchanger and the VRB Redox Flow Cell, an 80-90% re-chargeable scaleable non-toxic renewable battery. The Solar Sailor wings saves some 50% comparative fuel costs. These devices each save energy, they are tools of sustainability. A synergy focus of energy recovery will make it cost efficient.
The energy that is needed to sustain this comes at a higher cost, but the ongoing fuel costs are NIL since we’re using renewables, and there is no clean up cost or waste removal or waste disposal and far less greenhouse gas.
Figuratively speaking, Desal can leave on the tide and return with a full re-charge and load of fresh water on the next - without actually leaving the mooring.
The futuristic ability to seek out the best spots is critical to returning with a full load, and like fishing there’s a catch – but with computers and satelites we can follow in the un-maned footsteps of hurricanes. We could remote-control and literally catch enough storm to charge the energy systems on-board.
To save on costs todays would be stationary requiring a team of tug-boats to get around. After all, the job is a portable desalination plant.
Desal has certain advantages:
- Charge the battery over night – first time only.
- Battery accounts for mobility and travel distance from home.
- Daily routine governed by the tide wave wind and sun direction.
- Able to desal at Port.
- Able to desal at Sea.
- Seeking and Tracking – locate and find optimum 24 hour day wind wave solar resource.
- Massive – able to withstand storms and/or relocate.
- Massive – able to charge all systems within storms and return home.
- Energy Collector – gather energy from multiple wave wind tide and solar sources.
- Battery Storage – save the energy in electrolytic and hydro tanks for later recovery.
- Sea Water Desalination – on-board desalination.
- Water Storage – on-board water storage.
- Electrolytic Storage – on-board battery storage.
- Return to Base – when all systems are charged.
- Discharge fresh water – energy hydro recovery.
- This hydro energy saved could pump fresh water into the city water system.
- Conversely the U-pressure equilibrium pump-tide-leveler could.
- Portable – can sail to next destination.
- It’s not in my backyard.

And certain perceived disadvantages:
- Too expensive.
- Too much trouble to go through just to make water… but I’ll wait for the energy figures verses cost.
