If your interest is in solving global warming, there are thousands of people in universities, think tanks, etc. working on it. I think a single invention can only play a small role in that.
Heliostat solar collectors are a thing. At a small scale, you can use concentrated PV. At larger scales, it may become practical to use a turbine.
My general comment is that you're getting wrapped up in the details before proofing out the concept. You need to do the relevant calculations. How large a collector? How much radiant solar energy is that, on average? What's the conversion efficiency? And the estimated cost? Once you have some (approximate) answers to these questions, many aspects of your design are likely to change.
Also, that's not called a turret. Perhaps the word you're looking for is gimbal.
