Interestingly, at least one solution has been around for a long
time. It's a "two-part" solution:

[1] Run a Stirling engine to convert solar (heat) energy to
mechanical energy.

[2] Apply that mechanical energy to a second Stirling engine as a
heat pump to provide the cooling you want.

I've been working on a fluidyne-based version of this scheme, but
still haven't managed to get past [1]. (Glad you're not holding
your breath )
