Why making a device like this is such a challenge The Triton campaign claims its device filters water through tiny holes in the "gills" that extract oxygen. A tiny battery-powered "micro ...

Oxygen enters the river water from the atmosphere (via diffusion), from groundwater, and also as a by-product of the photosynthesis of aquatic plants. Oxygen levels in water can be expressed in units ...

A startling discovery made public in July that metallic rocks were apparently producing oxygen on the Pacific Ocean’s seabed, where no light can penetrate, was a scientific bombshell. Initial ...

The researchers suggested that the nodules could be acting as “geobatteries”, generating an electric current that splits water molecules into hydrogen and “dark” oxygen, produced naturally ...
