There are vast amounts of low temperature energy ie (45 – 50 C) that is rejected to the atmosphere through evaporation of water. I was reading a study about fish and prawn growth rates (particularly Kuruma prawns) adversely affected by lower temperature waters.
I would like to know if anyone had considered coupling the two industries on a large scale (ie 100 ha size farms) and if so, with what result? The concept is not exactly new, European countries have been utilising the “waste heat” for district heating of dwellings… But there is not much call for district heating in Australia especially since the power stations are located in rural areas.
So I’ve been looking for an industry in Australia that could utilise large amounts of “waste heat” in rural areas. I think that a primary industry on a large enough scale could warrant some further investigation. A brief investigation was done during a study for solar thermal desalination of the Murray.
