The real question is whether aquaponics can create higher quality food than organic produce, which is not subsidized. Subsidies are also unsustainable in the long run. The major costs in aquaponics are in the technology, which will inevitably get cheaper. If aquaponic agriculture truly represents an order of magnitude improvement in water use and space use, and can produce better food, it's only a matter of time before not even subsidies can keep traditional agriculture economically sustainable.

This is just what I needed to see after the front page of HN was dominated by bullshit about Surface and iPad mini. Finally, technology used to make something other than toys for bored rich people.
