Use of a Heliostat for Desalination
Desal is Not a New Idea
In 1974 Kuwait desalinated about 240,000 cubic metres per day.
By 1998 the Arabian area was producing 10 million cubic metres of fresh water each day.
By 2006 Australia was still producing practically no desalinated water at all.
But not only are the Arab States desalinating a lot of water - they do it very cheaply by using waste
heat from power station cooling systems.
Sunshine is Cheap
My proposal is to replicate the Arab approach, only using solar power. As far as I am aware there
have been no attempts yet to use a heliostat to power a desalinator.
A Different Heliostat
I have computer modelled the problems and written software to automate the process, and I believe
my designs are more efficient and cost effective than those in use overseas.
Now I want to build a proof of concept pilot project to show how a purpose designed heliostat can be
integrated with a desalinator.
I am looking for partners who would be interested in co-operating on this project, particularly
somebody with manufacturing and fabricating capacity.
The Objective
Using international estimates it would take around $100,000 to construct a 200 square metre working
demonstration that could desalinate 650 litres of water a day.
I believe I could halve that.
The Payoff
Heliostat powered desalinators could produce fresh water for less than one third of the current
domestic price of water in South East Queensland.
This would have to be a very profitable technology which will continue to be significant well into
the future.
