But I would pay for it.

Hah. Good comparison.

I didn’t respond for a while cause I kinda had something called christmas to enjoy. Exo equipment nowadays can hold up to 200+ pounds. Many years later this would improve a lot. The best actuators in PL can handle up to 2 tonnes on a small scale using hydraulics and all sorts of stuff like that. On a large scale for mechs they have actuators able to handle 30+ tonnes.
NLCO is probably the most advanced nation because the have access to space travel between their nations on Earth and back. Even then they don’t have self welding nano machines. They have drones on their ships that do repairments, but no smaller. Something that small can’t produce enough heat to melt metal together.

I upload everything of mine.

That ain’t bad. Pretty good

Depend on the type of material of the armor.
