Kind of worries me given what I hear about sand issues in construction

I have no idea but it just might be that a non construction grade smooth sand can be used as a heat sink.

I'm not a specialist either, but smooth sand might even be better, as it can flow more easily. If it's the case, the resource is virtually infinite.

I really hope so. I imagine there's different results for energy storage depending on the type - even if just slightly - and I'm hoping they don't overlap w/ construction needs.
