Biopod

Biopods are life support tanks filled up with isolation gel, equipped with a life support system and a neural interface. They are designed to isolate their user them from the outside world while keeping his body in a healthy condition for an indefinite time - possibly until he dies of old age.

Life Support System
The user of the biopod is floating in a tank of isolation gel, a gelatinous nanomaterial designed to hold him in a state of weightlessness while letting his skin breathe. Inhalation and exhalation are usually done through tubes inserted to the nose (tracheal intubation), through some podders decide to have a tracheal implant instead. Feeding and hydration is almost always done intravenously, bypassing the digestion system entirely.

Astronautics
Biopods are indispensable for interplanetary travel and especially space warfare. Compared to full-size crew quarters, they need much less radiation insulation (since isolation gel is an insulator itself), have practically no heat signature and podded crew needs much less food, water and oxygen. Perhaps most importantly, biopods allow their users to survive acceleration up to 30 g, more than twice as much as unpodded humans.

Networking
Many people working in the Network choose to install themselves into a biopod both to make deep dives more healthy and comfortable and to decrease their cost of living.

Side Effects
Correctly functioning biopods have no biological side effects and can keep the body of their user healthy for decades. However, long-term separation from the real world may result in schizocosmia, a serious and untreatable mental disorder. Through schizocosmia is caused by neurodiving and not the biopod itself, the pod makes regular deep dives much easier and safer, helping neuroaddiction and eventually schizocosmia to form.
