So when the flip starts you basically have a few seconds to strap in before getting tossed around the capsule as it tumbles down the side of the berg right? Even if you are strapped in I feel like surely you're going to come out very concussed at the least.

His idea seems to be to detect the approximate timing of a flip or roll with sensors and then strap in and wait for it to happen. I have some serious concerns though lol. I mean if the ball rolled off a cliff on the iceberg and fell into the water I’m pretty sure it would be like trying to survive a crash at terminal velocity, and I doubt the racing chair would handle it.

That is what I was thinking. Are you also strapped down for the toilet? It's going to be messy when it flips while you're evacuating your bowels.

And, overall, it seems incredibly pointless! If you have a survival ball like this, why not just let it float? Why put it on a dangerously unstable surface?

I think that's the whole point? No "normal" person would think doing this is a good idea -- he wants the thrill of the ride with a minimum of recklessness.

You couldn't pay me enough to do this.

Not saying it’s full-proof but I believe it is a cage inside a ball w rollers so that the outside spins while the inside is at least somewhat stable. Nonetheless, they do mention that a full inversion is a worst case scenario due to the suddenness

No it’s a self righting interior. Read the article.
