In college I worked on a project studying this. You can run a generator off the methane but it requires filtering, which makes it less profitable, so most landfills and waste treatment plants just burn off the gas with a flare.

You can’t without specialized equipment and specially trained workers. A car built with that kind of precision would cost many millions of dollars.

At my old shop they gave the job of running the EDM to the old dude who regularly fell asleep during his shift.

What I’m saying is that those machines are slow as hell.

The major structure of most cars are made of stamped and spot-welded sheet metal, usually steel. IIRC Teslas are made mostly of aluminum, so some of the parts might be extruded, cast, and/or machined, and they might also be riveted and/or bonded (glued) together. The body shell shouldn’t need to be very precise, maybe +/- .03" at most. On the other hand, the dies that make the body panels are under tremendous pressure and need to be more precise so that they can consistently turn out good parts without wearing down or breaking.

I wonder if he’s inventing arbitrarily rigorous standards as an excuse to delay production again

Depends on what it is. Some things like ball bearings need to be precise in order to work efficiently, but car body panels definitely do not need to be that precise. Pretty much nothing on a car needs to be within 10 microns.

Not so much the cans themselves, it’s mostly the machines used to manufacture the cans that need to be precise so that they can stamp out hundreds of cans per second without tearing or wrinkling the thin aluminum.

Here’s an explanation of the process

Modern day Howard Hughes, it’s not a question of if he’s going to collect his own urine, but when he’s going to start selling it as mineral water.

I used to work for a company that made stamping dies for aluminum cans, and some of those dies had tolerances close to .0004", because the aluminum is very thin and could crack and tear if the dies were not made precisely. The cans themselves are not that precise, they just need to hold beer without exploding. I can’t speak to Legos, but cars absolutely do not need this kind of precision, not even in the bearings. And especially not in the sheet metal body panels.

That information is relevant to zero people because it’s impossible to make anything out of bent sheet metal with a .0004" tolerance. He may as well have asked for a working car made out of cheese.

I would download so many cars
