Well, the reason we're doing this offshore is because if you look at our coastal cities, there isn't a choice, because we're going to use waste water, as I suggested, and if you look at where most of the waste water treatment plants are, they're embedded in the cities.

This is a greenhouse designed for arid coastal regions, and the way it works is that you have this whole wall of evaporator grills, and you trickle seawater over that so that wind blows through, it picks up a lot of moisture and is cooled in the process.

This helps to widen regional disparities, especially between eastern and western China, with the wealthiest regions being those that have benefited from high concentrations of FDI.
