How It Works

Air in. Water out. Sun does the rest.

Humid air flows in

Every cubic metre of air at 35°C and 65% humidity holds up to 27g of water vapour. The device pulls air continuously across its cold surface.

Solar cools the plate

The solar panel powers a Peltier module — no compressor. The cold side drops to 8°C, below the dew point. Vapour becomes liquid water.

Water drips and filters

Condensed water drips through an activated carbon filter. Clean, ready to drink or feed to plants directly.

Free, every day

No electricity bill. No delivery. No plastic waste. Sun rises, device runs, water comes. Replace the filter once every six months.

Hot Climate Advantage

The hotter it gets,
the better it works.

Hot, humid coastal climates are ideal. Mediterranean summers are a goldmine, not a challenge.

Tel Aviv: 60–80% humidity in summer

At 35°C and 70% humidity, a cubic metre of air holds 27g of water. The device processes hundreds of cubic metres per day.

300+ sunny days mean continuous power

Israel gets 10+ hours of usable solar per day in summer. The Peltier runs all day and stores charge for overnight production.

Works anywhere water is scarce or expensive

Cyprus, Greece, UAE, Morocco, Mexico. Any place where water costs money or infrastructure is unreliable.
