I had to hang around home a little longer than usual. There's a Goodwill dropoff place across the street from work, and someone left an old pressure cooker outside while the place was closed overnight. Imagine the uproar, cops and fire trucks and bomb squads and massive traffic jams. It's over now, so I guess I'll mosey over there and design something.
I wonder if pressure cookers could be redesigned to make them less useful for off-label applications.

Sure, and let's redesign iron pipes so the end caps don't screw on properly. ;)

Prolly not -- it has to have a fairly high rupture strength to do it's job, and it's that rupture strength that's going to make for good shrapnel. Even if you did something like design it with engineered blow- outs, a bit of work with a dremel tool or even a chisel could turn it back into a great big grenade. So maybe a bit less useful, but not much.
And, there's a hell of a lot of old pressure cookers out there. Do you really want a government-mandated drive to have people come to your house and take your pressure cooker away, in return for enriching some offshore factory owners?

I'm looking for work -- see my website!
I don't think a pressure cooker has to be overly strong to hold the 15 psi most work at. I expect they are greatly over designed so that if the pressure valve is stuck they won't blow so readily.
Is that necessary? Look at this one, it reminds me of deep sea diving gear!
A36 is 58000 to 80000 psi. But that is ultimate strength. Not yield strength. And one should probably use a sifety factor of about 5. So one should use about 7000.
Hillary would ban pressure cookers, or at least require registration, a training certificate, and a background check.
Hillary believes Americans have no individual right to own a pressure cooker (or a pencil--you can put out an eye with those things), and will appoint a Supreme Court that agrees. (After all, the Constitution doesn't mention a right to own pressure cookers, and it was something the Founders of the country clearly could not have anticipated.)
Probably not. Nobody has ever bothered with anything like that, and Hillary Clinton isn't exactly an innovator.

I think James Arthur is animating his cartoon version of Bernie Sanders, ra ther than Hillary Clinton, and rather forgetting that even Bernie Sanders i s a modern socialist who is perfectly happy to let the free market do what it does well - sell pencils to people who want them - and only intervenes i n areas where the free market doesn't work too well - health care and educa tion do come to mind.
The free market can degenerate into cartels and monopolies, and one needs t o regulate it closely enough to prevent this. It works badly in "natural mo nopolies" - remember ENRON - and for stuff like education where the product and the customer interact in unpredictable ways. Trump University isn't an example of that particular problem - it was just a con trick.
No need to be charitable about Trump - he's got his own charitable foundati on, and it's charitable to him on a scale that makes any contribution from the rest of us quite unnecessary, as well as inappropriate.
James and his friend gave us one for the cabin in the mountains, after an unfortunate batch of mashed potatoes. It's useful at 6400 feet, probably more like necessary at 12,000.
