Pressure Cookers are usually plug ins. In fact, I’ve not seen a battery operated one. How does this work without a plug in recipticle? Do they have battery operated pressure cookers?

There are probably millions of stove-top pressure cookers around. They are still being made, if I'm not mistaken.

Just saw one at Walmart recently, kinda spendy, plus its becoming a lost art pressure cooking. As far as a bomb casing it makes near perfect sense, you can seal it up, run any det wires through the pressure relief port, seal with silicone and then spray the exterior with a sanitizer.
Its just a casing, not a cooker, also a crude slow burning powder can be used. I work with high pressure hydraulics and have seen the destructive force upon a cylinder with just 200psi.
