P.S. any tips on angle-wrap-respecting code to determine if a supplied angle is inbetween (on the short side) another two supplied angles? Imagine "spinning a bottle" and then checking if the resulting angle is within a certain sector, the sectors not all being equally sized or spaced, so it needs to be a genuine check of "is it between these sector limit angles".This problem is trickier than simple comparison due to wrapping issue, but still easily solvable by splitting circle in two regions.
Like the EM drive,
https://thedebrief.org/nasa-veterans-propellantless-propulsion-drive-that-physics-says-shouldnt-work-just-produced-enough-thrust-to-defeat-earths-gravity/
this one uses a capacitor. Instead of piezo (not that a piezo is not a capacitor) , but it sounds similar. That is that there is some unequal force in a polarizing material which leads to thrust. Not a (weak) photon drive.
Not surprising, since the capacitor’s leads have to be made of a material compatible with its own electrolyte!capacitor leads are tin plated iron (rarely copper)
