There's plenty of dissolved oxygen in H2O – it's the “O”, you know. Fish extract oxygen from water--it's how they breathe. We humans can't. Until now.
Israeli scientist Alan Bodner has created Like-a-Fish, a breathing device that can literally spin oxygen out of water. Not only is it great for divers, but its technology can also be applied to submarines and in underwater habitats.
In 2015, Like-a-Fish partnered with Italian company Inova, whose new hydrofoil submarine The Atlantis is hailed as "a futuristic, multipurpose over and underwater travel vehicle."
From the Inova press release: "The Atlantis is the first submarine to be equipped with the 'Like-a-Fish' patented technology, a new system which can extract breathable air directly from the water during travel. This is why we call it "The Submarine with Gills.”
Like-a-Fish: a brave new world under the seas, made possible by a country that was built on the desert.
