Interesting, but they neglect to mention why desert sand is unusable.
In case you don't know, desert sand is very smooth, which means that it doesn't bind at all in e.g. concrete. For cement, concrete etc., you need sharp sand, which has more 'sharp' bits for things to bind to.
Easy. Just put the desert sand in a magic bullet to make more edges.
Bake it, then crush it? I guess it's just easier to pick it up as long as there's some laying around.
