The problem with losing 5% of the energy in the motor windings is that they heat up. With superconducting windings you run smaller-lighter motors.

I would guess overhead lines and catenaries for some portion of the route rather than dragging cables around.

How does the temperature come into play?

To turn the magnet off you need to get the current out, I don't see why raising the temperature would make that easy.

It still might be worth cooling this with LN2, in many applications, assuming critical current and critical field scale up as temperature decreases as they do with other superconductors.

I don't think mistake is a possibility. If it doesn't superconduct at room temperature, the photo of it levitating has to be faked.

They should just mark the tires so you can tell at a glance. It's great fodder for the commentators to go on about the different tire choices each team made.

Do they even have ballast tanks? I saw mention of steel ballast they drop at the bottom. The biggest benefit of reduced weight on this thing would be minimizing the size of the crane and surface vessel needed to deploy and recover it.

There is a legitimate use for a steering wheel. The ability to remotely command full throttle on a car is useful for what?

Giving the vehicle owner an easy button to crash their car remotely is going to be a liability for the manufacturer when the obvious happens and it's used as murder weapon.

The ability to remotely send commands that spoof the accelerator pedal should probably be considered a safety defect. Not just if Jake's Auto Repair can do it, but if Ford Motor Company can do it.

The moon has large enough density variations that you can't analyze low orbits as though it's just a point mass.
