This can been shown with only a cursory look at 3 and 5 phase power then a small amount of group theory. Unfortunately power electronics engineers are some of the least mathematically inclined people in STEM, so no one has tested this on a linear power system. Also it's very difficult to get multiphase systems to stay a fixed time shift apart on an active power grid. So even people who do realize the potential have reasons to not bother.
