Floating power

This is an impressive photo, from a Time magazine story on China and renewables:

And how's this for the symbolism:
....the world’s largest floating solar farm on a lake formed on top of a collapsed and flooded coal mine just northwest of Anhui province’s Huainan city. A tapestry of 166,000 glistening panels bob and bask below an ochre sun, producing almost enough clean energy to power a large town, as fish break through the inky water all around.
Other photos in the story show that its construction is pretty low tech - the solar cells are on simple plastic floats.

I would have thought that this is a pretty good idea for water storage dams in Australia - I'm sure I've suggested this here years ago.  I don't think there is any substantial risk of polluting the water if some sink, is there?  Furthermore, in a hot area, the coverage might help reduce evaporation, I would have thought.

When am I going to see this on , say, the Wivenhoe dam near Brisbane?
