Hyperloop One engineers demonstrate the power of maglev using spinning arrays atop a copper plate. Despite weighing over 100 pounds, the gadget floats and could hold considerably more weight.
Quoth Veritasium:
Obviously this “quadcopter” is a demonstration device, showing how moving magnets over a conducting surface can generate levitation. It has not been optimized to minimize losses or be an efficient mode of transport. I still think it’s pretty cool. I’m used to seeing light things levitated by induced currents but not a 100+ lb machine.
He does a great job of showing how the mechanics work, and he demonstrates another form of maglev that gets extremely hot. All very interesting!
