This is either the scam of the century or a pretty ground-breaking piece of news. An Israeli company has patented and prototyped a tankless underwater breathing apparatus that separates absorbed gas in water. By using a small centrifuge, this system extracts breathable oxygen in depths up to 200 meters. The system can run for an hour on one battery.
I did a bit of due diligence and couldn't find anything refuting these kooky klaims, so I'm going to accept this one as an interesting future technology that may allow us to live among the fish like brothers and sisters. (Thanks, Roland)
