What an odd choice of words for a headline. Expecting something to do with big balloon tyres that could drive on water or something.

They meant hydrogen powered wheeled excavator. I could understand it if it was just the hacker news title but the article headline doesn't either. Not sure if this human error, bad AI or deliberately click bait.



No, I think it's the way they call them in the industrial sector. You have "wheel excavator" or "track excavator" depending on its ways of movement.


The headline was clear to me. Maybe I'm already vaguely familiar with excavators, though.
