From seawater to fresh water.
A solar-powered emergency water still for boats. Its inflatable ribs need less air to pump and leave more room to condense.
The first batch goes into production when 500 units are committed. If we don't reach it, private customers get every payment refunded in full.

Runs on sunlight alone. No battery, no generator, nothing to charge before you leave port.
A few strokes of the pump and it stands. Deflated, it stows in a locker until the day you need it.
Drinking water collects in its own bag, so it never touches the seawater in the base.
Make fresh water yourself.
Three steps, one button. Try it.
- 1Pump up the ribsTap the orange button 5 times. Each tap pumps air into the ribs.
- 2Let the sun shineTap the button to let the sun rise. You can also drag the sun yourself.
- 3Collect fresh waterNothing to do: water evaporates, condenses on the dome and drips into the bag.
- Illustration. Real output depends on sunlight and temperature.
- 1Fill it with seawater
Pour seawater into the base and let OA-SEAS float next to the boat or sit on deck. No pump, no power cable, no filters to replace.
- 2Sunlight heats the water
The clear dome traps the sun's heat. The water warms up and starts to evaporate. Salt and dirt stay behind in the base.
- 3Vapour condenses on the dome
The vapour rises, meets the cooler skin of the dome and turns back into drops. The ribs keep the space open so there is plenty of surface to condense on.
- 4Fresh water drips into its own bag
The drops run down the inside of the dome into a separate fresh-water bag, kept apart from the seawater from start to finish.
Less air. More water.
Most inflatable stills hold their shape with one large air chamber. OA-SEAS uses slim inflatable ribs instead. You pump less, it packs smaller, and the space inside goes to condensation.

Production only starts once 500 units are committed by 12 January 2027. If we don't get there, private customers get every payment refunded in full to the original payment method.
