I've been following Sam for awhile, his business model makes heavy use of outsourcing production of components to skilled partners. It's no sweat off him if he makes the Impulse stove in California or not.
His point is that it's impossible to manufacture much of anything in California if you aren't grandfathered in. Seems pretty important for economic and security issues.
The electric induction cooktop he and his team has made is pretty cool! I'd check it out.
I'm not sure I agree.
Unless you believe there needs to be a plan for CA to secede in the future and thus it needs to be self-sufficient, why does manufacturing need to be in CA? As you stated, the Impulse stove makes heavy use of outsourced manufacturing to other parties; as long as those parties are within the US (which I'm not claiming they are, but there are states like TX that are far less concerned about environmental impact than CA is and thus could pick up any such slack), why is there a security concern here?
As for the economic concern, it seems like this is backwards: I'd argue it's the HCOL that drives industry with the need for low-wage labor away to non-CA locations. There's nothing stopping non-polluting corporations from working and hiring large numbers of people in CA.
