Checked his Twitter feed, he talked with a few persons about their gear and how to help with pumps, power etc. So the sub wasn't the only thing he did.

And yeah, he probably doesn't have all the domain knowledge needed, but I reckon he had some help. Example; the 6 or so people seen on the video when they tested the tube.

I really can't see why people are bashing him. Yes, he was public about it, but he also created something that seems to work, and if it's a prototype, that prototype can be used for further development. It feels like nothing speeds up R&D like a crisis.

Let's hope he keeps working on it now and delivers something viable for the next rescue.
