I have the impression that there are three seperate bits involved
First site using the lens to heat the oil then use the oil to generate elecy or store
energy in salt
Second site using mirrors to heat water make steam then elecy or store energy in salt
I would be very interested in a small scale system storing energy in salt -
RMH to generate electricity and heat home anyone ?
