And yes, now it is developed by the west for the west. My line of thought is which branch is later easier adopted for production and usage along the equator, and my bet is on really on small thermal, which I think will benefit from advances in large solar.

Molten salt is storage and storage depends usage. But yes, if you need molten salt storage for it to make sense you are probably on a technological level where PV is as attractive as thermal.

And of course, for the hybrid system linked to above that concentrates the solar onto a CPV module and harvests heat from that module ~ which also serves to provide the required cooling ~ the heat is more likely to be used directly, for solar Heating / AC, or solar hot water, or industrial process heat, so there is not necessarily any central thermal generator in the system. That is an especially interesting approach for urban uses in low income nations.

I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
