Yull Brown, born Ilia Georgiev Valkov, was a Bulgarian-born Australian inventor known for his work with oxyhydrogen. He is particularly recognized for claiming the discovery of a unique form of oxyhydrogen, referred to as Brown's gas or HHO. While some of Brown's theories are based on real physicochemical phenomena, many of his more ambitious claims—such as using water as fuel and the capabilities of Brown's gas to vaporize tungsten or neutralize radiation—have been dismissed by modern science both theoretically and empirically.
