NUS researchers invent 'humidity digester' to keep rooms feeling cool at zero energy cost

A team of researchers from NUS developed a hydrogel which, when combined with some chemicals and a thin carbon mesh, can absorb water vapour from the air and break it down into hydrogen and oxygen molecules, lowering the humidity in a room.

SINGAPORE - A team of researchers from the National University of Singapore's (NUS) Faculty of Engineering has invented a novel way to lower the humidity in a room without using energy.

The team developed a hydrogel which, when combined with some chemicals and a thin carbon mesh, can absorb water vapour from the air and break it down into hydrogen and oxygen molecules, lowering the humidity in a room.
