What surprises me, in a way, is that photovoltaics are literally 3,5 times cheaper than just mirrors reflecting light onto a tower. It got REAL cheap. Wish it'd go further!
The mirrors are the not the expensive part.
What is? Thermal to electricity conversion?
Yup. Steam turbine generators have a lot of moving parts, and moving parts break
Got it, thanks
