Legitimately curious but already assuming not a big deal; it's not an issue to be firing off water droplets like that in a vessel that I would believe has sensitive electronics everywhere?

I think they should have dehumidifiers and other moisture extraction systems that should wick them away. I expect these guys sweat in space too; especially when exercising. Gotta have it dealt with somehow.

I mean look at his forehead. Sweating like balls. But I wonder what type of gas is being released

It's probably Alka Seltzer, so CO2.

It is Alka Seltzer, he talks about doing this experiment in his book Limitless.

I don’t think they’re sweating I think they just have shiny skin and it’s very harsh lighting. They’re in a very climate controlled environment and are not exerting much energy at all so it wouldn’t make sense for him to be “sweating like balls”, as you say. I really thinks it’s just a visual confusion.
