Sorry but this comment is completely ignorant of the chemistry & manufacturing… you can make some shitty unusable glass with it, but unless you waste an unsustainable amount of resources to try to make the problems less apparent, a majority of desert sand is too low-silica to work. It’s a problem with the material, no new glass processing method will change that.

And if you do decide to use desert sand, it’s practically a logistics nightmare, especially considering you’ll likely have to be centered in one of the few deserts made of sand (most of which are in North/South-East Africa and the Middle East, but also Central Asia, Australia, some parts of the Americas). But even if you did it’s not sustainable or practical, and it most probably won’t be in the future, there’s a reason glass manufacturing plants smack dab in the middle of sandy deserts have to import their sand.
