As noted in that discussion, there are different types of sand – (ironically?) the growing desert is not usable as a construction material; the individual grains are too small and spherical, in construction sand the grains are coarser and larger. Why is why we have the situation where Gulf states import some of the sand for their construction boom even though a huge proportion of their land is desert (that is to say – sand).

edit: so no synergies unfortunately!

So what you're saying is someone needs to invent a cryptocurrency where the proof of work is measured by the number of spherical grains of sand you coarsen?

We need to launch an ICO here. The Internet of Sand (IoS) is the future. Every coarse grain will have its IPv6 address which is retained in a blockchain for tracking, making "intelligent concrete" the very fabric of architecture 4.0.

According to some research papers [1] [2] it may be feasbible to use desert sand for concrete at least - However, my knowledge about construction is very limited so I may have misinterpreted the findings.
