I fix giant metal birds that light themselves on fire and scream really loud to fly across the sky. The kingdom heavily regulates who fixes them, how they fix them, and who flies them to make sure everyone is safe.
using superconducting magnets the cold will actually be beneficial?
e. caputures by solar panel & stores electricity with ultra dense capacitors, insolation at a rate that makes it economical
The idea of a flying machine isn't new. Though convincing anyone that you fix them might get you branded a liar, charlatan, or witch. Depending on your audience.
Also the fact that they are made of metal. Heck, just the idea of lighting a fire below deck of a ship made of cast iron back in the civil war was seen as something insane.
