Generating electricity by boiling water used to be the cheapest option, but nowadays it’s a bottleneck that itself is way more expensive than the alternatives that people actually build.
It only got cheaper with time, though. It’s the alternatives (PV, wind, batteries, gas) that improved a crazy amount.
No, neither will it be cheaper.
People stopped building those some years ago.
(But those incredibly expensive concentrators with a single tower are more efficient. Nobody is building those anymore either.)
They used to be cheaper. Solar is bananas cheap now

I assume not efficient enough to justify cost
Turns out that sunlight is very cheap. You need a lot of efficiency to justify any extra cost.
PV panels have very low maintenance needs
