Tesla is facing issues with the bare metal construction of the Cybertruck, which Elon Musk warned was as tricky to do as making Lego bricks

to build it to that accuracy the car would have to cost millions

To build it with that accuracy would be physically impossible. Guess he forgot about thermal expansion and contraction. Guess he forgot about the weather...

Nah, not impossible people build stellarator type Fusion reactors with large freeform metal parts in that tolerance region that are exposed to liquid helium.

Does not change the fact that all materials expand when temperature rises and contract when temperature cools. Plus different materials have different temperature expansion coefficients.

[–] botengang@feddit.de 6 points 1 year ago

So does the stellarator. What's the argument here?

[–] HeneryHawk@thelemmy.club 6 points 1 year ago (1 children)

Most. Water, for example, takes up more volume in spaces when frozen

[–] over_clox@lemmy.world 1 points 1 year ago

True, water is weird like that.

just define a temperature :D
