Rotoverter at first glance appears to be overunity but vars are not real power. voltage and amps must be in phase or they are not present at the same time. They need power factor correction added to all output measurements.  All that is left for this to work is convert imaginary power to real power lol. lots of voltage with no current one millisecond and lots of current with low no voltage the next millisecond is not real power it is an illusion of power. Efficient resonance idling with no extra power is useless. Except to avoid the inrush current of the next startup. If your idle time is short it may be worth implementing into a working motor but not overuntiny and most likely better to just shut the motor off during idle times. Run capacitors are implemented to keep motors efficiently running under load and have been for a long time.  Then motors can be shut off during idle no reason to leave a motor running rotoverter mode at idle if no work is being done just shut it off. Only a very small advantage to this  RV mode and cost of switching in and out the rotoverter mode for a short idle is foolishness with the quantity of motors that could be in a single plant.

I'll give you an example where a motor, converted to RV, blows (literally) everything away.
Take a 120 VAC industrial fan, the portable ones used on warehouses, etc., which have a diameter of around 4  feet.
Those fans usually consume around 350 to 400 watts.
Now, take a three phase motor, a small 2HP, and convert it to RV. Idle watts at full spin, 1750 RPM,  is about 40 watts (tested) after modded,
Now throw away that big fan motor and change it for the modified RV and tune the run cap.
You'll be running now at around 60 watts (with blades installed) at full speed. (tested)
There you have it. An RV fan, way more efficient that any other fan of it's size.
