I got in on the second season of the IP craze. 6L, stainless pot, didn’t actually think about the pressure vessel, I’d have to check if it was non-stick. But it does well. I think if I got a decent air fryer 80% of my need for a stove would be negated.
To add to this, the Primitive Technology channel on YouTube shows how to make a fire with two sticks. The key to his preferred method is a harder stick with a point and a softer one with a notch. Then you have a lot of work, prep, and trial and error ahead of you.
