Where can we buy one?
What sounds like science fiction is unfolding in marine biotech facilities where underwater respiration is becoming biological. Engineers created membrane systems inspired by fish gills using hydrophobic polymers that separate dissolved oxygen molecules from H2O at 92% efficiency. Test divers breathe normally at depths to 60 meters with zero equipment failure across 2,400 hours of submersion.
The gill unit costs $28,000, mounts on chest harnesses, and operates on ambient water flow. Navy applications include covert operations and submarine escapes. Recreational diving is being transformed. Scuba tanks and decompression sickness are becoming obsolete. Humans are evolving aquatic capabilities through engineering.
