  • I guess that depends on your definition of a flamethrower. To me, a flamethrower is primarily a weapon. And what you are describing is a roofing torch. Googling it now, I can’t seem to find anyone calling them “roofing flamethrowers”. Flame gun — sometimes — but never actually a flamethrower.

    So the legality is probably an issue with not being specific enough with the tool/weapon differentiation. I don’t think actual flamethrowers should be legal.










  • You’re right, haven’t heard about that one. They actually do use superconducting magnets on a train that runs along a magnetic track.

    But I feel like my feasibility comment still stands. It seems like all they had built is a 18km test track, and there’s some info about extending it to 48 km, but it doesn’t seem like the extended part uses superconducting tech yet, it only mentions regular maglev. The Tokyo — Osaka line is planned for 2037. So yeah, its technically possible, but it’s not like you can cover Europe or the US with this type of track for any sensible amount of money.

    That’s the cool part about room temperature superconductors, they make this type of tech possible on much larger scales.
