Desert sand isn't useful as it's too smooth and has properties nearer dust or silt than sharp sand.

- HarryHirsch 7y agoThey talk about the three main uses of sand being concrete, glass and electronics (the third one is actually wrong, only 15 % of silicon produced ends up in the semiconductor industry, the rest is used in metallurgy). I can imagine that one could use desert sand for the last two purposes but don't know how much of an impact that would make.
