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.
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!

In 1992, University of Melbourne researchers TT Lim and TB Nickels wrote a scientific paper titled “Instability and reconnection in the head-on collision of two vortex rings.” The research so inspired Smarter Every Day’s Destin Sandlin that he launched his own research effort to study the phenomenon and capture it using high-speed video. Four years […]
Quantum physics gets real weird real fast, and one idea gaining more currency of late is the concept of quantum retrocausality, where a decision made in our experience of the present may influence what we experience as the past. These aren’t a bunch of Time Cube type cranks, either. From a helpful overview by Lisa […]
