Humour first
Communications - cordless phones are pretty cheap
Regenerative - Hook it up like a trolley bus

The Chorus Motor is one very clever piece of kit.
Virtual windings (bit like the
Company) that actually harness the normally detrimental harmonics. On the fly it can perform as if many different style of motor, in one, and with greater efficiency than each regular motor/generator. Phenomenal power density. One of the big problems with traditional A/C motors is the size / capacity of the controller to handle the relatively large transient peak power requirements at start up. Industry leading
Semikron are handling that side of things. Neat is a word that springs to mind.
Safely too. A DC motor has a failure mode akin to an
arc welder. (Thought they banned smoking on flights some while ago). An AC motor fails to a non resistive open circuit state. An AC Chorus® Motor is the nextgen.
If I'm not mistaken, what held Maglev back for a long while, was the complexity of the electronics managing the magnetic field. All electric motors manage magnetic fields. Thus there will always be similarities. Mathematically a linear motor is simply an infinite rotating motor.
Come what may, WT technology has to safely, practically, economically reconcile itself with operations at airports.
I must thank you all for your continuing valued input.
