Brisbane physicist Dr Ian Edmonds has had a novel idea for transporting water from rain soaked North Queensland down to the drier regions of South East Queensland and NSW.  Dr Edmonds has suggested floating large volumes of fresh water down the Australian east coast in large plastic bladders.  With the natural current that flows from north to south down the East Coat of Australia, Edmonds suggests it would be cheaper and more environmentally friendly than desalination plants or pipelines.

I think we need more novel thinking like this to solve our water woes and to solve the global warming crisis we're facing.
