It's on the SpaceX website. That Musk was doing this through SpaceX is news to me.

He said yesterday he's not "doing" it at all. He's just throwing an idea out there, but not actually building it. In that case, I guess he can just use one of his companies websites.

maybe Spacex has built a hardware tech demo. They have a flexible factory.

I don't think he is - he has to put the information somewhere since he doesn't own a personal website

I admit I didn't know that either, but does that really make it worthy of being the top story on HN?

Nope. But now we've got a great dataset of users that blindly upvote stories.

Many people were wondering under watch branch of the "Elon-mpire" this would fall under.

eg why not put it on elonmusk.com? Or its own website?
