we could pick a country that hasn't signed the treaty and put the city there.

We could pick no country at all and make a full scale replica of Atlantis from Stargate Atlantis. Which has the added benefit of existing plans and schematics and being able to fly to Mars when we get board of the oceans.

Or we could pick a) an uninhabited Island or b) not have it on land, have it floating. Or c) have it flying. A 10km * 10km * 1km bag of Hydrogen or Helium can carry 80,000,000 mt at sea level. Admittadly it would have to use H2 as we don't have enough Helium, which is a bit of a fire risk, but if my idea bears fruit it would be able to lift 125 million tons with no fire risk.

Craazy idea, but it'll happen.

option b) plus c) gives you SG A again.

Does anyone know if refridgerated condensation towers could be effective in hot dessert regions?

I think you'll have to tell us what a 'refrigerated condensation tower' is first... Sounds interesting though...

I just had a look at the Vertical Farm Project website. It seems as though they've added a lot more info on there. Check out their list of recent articles here (at the top), and heaps more images here.

If you assume that power supply is plentiful but water is not, you could envision building say a 500m tower with an open structure shaped perhaps like two cones one inverted. If you then massively refridgerated the structure, two things should happen, firstly the dew point of the air should drop allowing what water there was in the previously hot air to condense and be guided done to the ground and into an underground resevoir, secondly the cold air should sink drawing in more air from further up, where ther should be more water. maybe.

Interesting concept. Reminds me of the 'WindTraps' of the Dune books, or the 'moisture evaporators' of StarWars.

Seems like even if we had loads of energy, cooling an entire tower to condense what little water there is in a desert environment would be a waste. Desalination plants would be immensely more efficient.

From the guys over at Cquestrate.com comes another interesting read and video too: http://www.cquestrate.com/get-involved/growing-biomass-in-arid-environments
