Many of us have seen solar power plants of this type, and making primitive versions of these mirror dishes was the goal for some of us, for example this case...
Some of this stuff would be very easy to copy or modify.
in a Missouri USA they pump water up a hill then drain it back when demand increases, it’s a rather large system. In Al’Abama an individual is using underground salt water tanks to store hot an cold salt water for HVAC and electric on his farm.
personally… I use solar electric to drive a 10k/btu AC and scavenge the unit’s waste heat as a food dehydrator, storing food is also storing solar energy and the AC keeps is pleasant indoors.
