Yes, I agree this is vastly over-engineered. There are commercial solar farms that actively point toward the sun, but many (most?) do not, because they may fail. Before medicine, I studied and worked in renewable energy: in medicine, simplicity in critical engineering problems is more obviously important.

In this solar project, the metric should be a comparison to the yield from pointing at the sun based on lat,long, and (earth) time.

Really, the analysis would have to include anticipated costs of installation and maintenance in comparison to a dumb array.

Perhaps the ingenious author could consider xy or xyz movement in an intermittently shadowed environment instead of 2-axis rotation. This might be be a better job for machine learning, or just a well-known control system problem.

Physician, anesthesiologist speaking. Intravenous phenylephrine widely used, effective. No good in stomach.

Doctors struggle to harness all the historic use and evidence for treatments, sometimes based on great evidence. Often evidence is the best that can be had given available resources.

Drug companies hiding data (derived from volunteers and patients) is wrong, and a problem. Selective publishing of only positive findings in medical journals is common. Careers depend on publications. But despite these pressures, most doctors think hard about these issues, and do their truthful best for the patient in front of them, given the imperfect knowledge available.

OTC labeling is deceptive at best. Placebo only works for a few things.
