The Problem

TANKS ARE 100 YEARS OLD.

We still carry heavy, flammable gas cylinders in an era where they should be obsolete. DAIVIN! changes everything.

diver
Helium price increase since 2000
400-1000%
Problem 01
Heavy, dangerous tanks
Divers carry bulky cylinders of exotic gas mixes some rare-earth gases that are running out. Helium has increased 400-1000% in price since 2000.
Problem 02
Immense logistics bottlenecks
Refilling, transporting, and managing dive cylinders creates massive operational overhead for every dive operation worldwide.
Problem 03
Technology from 1943
Modern dive gear is built on the same principles as equipment from the 1940s. The ocean floor is still accessed with century-old logic.
The Answer
Water contains everything we need
H2O the molecule present at sea, land, and space is the only oxygen source we will ever need. DAIVIN! extracts it on demand.

We as humans need air to live. We breathe oxygen every day and take it for granted — until we go and push the limits of our terrain. Whether underwater, in high altitudes, or even space. The only answer lies in water — the molecule available on Land, Sea, Air and Space. If we ever want to live in space, tap into our underwater domain, or save our loved ones when in need — we must evolve.
