Model solar concentrator. It works without the focus moving.

Reason for half dishes is access to the Stirling engine or stuff you are cooking.

Reason for 2 dishes is you have the center of gravity on the rotating axis of the thing with year round seasonal adjustment.

Reason for equatorial axis (also called polar axis) is so your daily tracking is really simple. Just a simple constant speed rotation. If anyone wants to try this "quick and dirty" you could cut a sk14 in half and use that as your 2 dishes. Amazing: it is a year old and still untested!
