Slingshot requires a combustible fuel source--burning wood, coal, etc--in addition to the electricity. It's a step forward but it's not truly "clean." The device itself is also not cheap; it is estimated to cost several thousand bucks.
Nanotubes are a possible candidate but the technology just isn't there yet, and desalination with them still require a lot (albiet less) of energy. It's also not particularly cheap to make carbon nanotubes at this point in time; if it was, carbon nanotubes would already be replacing things such as steel due to their strength.
Modern desalination tends to be either "we evaporate it" (which usually requires burning fuel; Slingshot uses this premise) or "we run it through filters." There's a reason why countries that actually use desalination on a large scale tend to be ones with a lot of fuel but not a lot of fresh water, like certain nations in the Middle East.
