&lt;br /&gt;
Born as Ilya Velbov in Bulgaria, in 1922, Yull Brown moved to Australia in 1958 where he worked as a laboratory technician. Trained as an electrical engineer, Yull Brown filed for patents for Brown&amp;#039;s gas in 1974, 10 years after William A. Rhodes filed for similar patents for an HHO electrolysis unit.  Most of Yull Brown&amp;#039;s demonstration were conducted with welding torches where he showed that hydrogen and oxygen could be separated from water and then burned cleanly using many different objects. There&amp;#039;s even a [http://www.youtube.com/watch?v=K6bfpdBUa2Y video] where Yull Brown not only welds and burns bricks with his Brown&amp;#039;s gas generator, he also burns his own arm to the point where his skin bubbles.&lt;br /&gt;
&lt;br /&gt;
Yull Brown spent most of his life convincing others of the commercial viability of his product. He spent 30 years of his life and was able to acquire upwards of $30 million from investors towards commercializing his product.&lt;br /&gt;
&lt;br /&gt;
On May 22, 1998, Yull Brown died at Westmead Hospital in Auburn, Australia. The HHO gas is still called Brown&amp;#039;s gas in memorandum to Yull Brown. - [http://www.hydrogen-gas-savers.com/yull-brown.htm Hydrogen Gas Savers]&lt;br /&gt;
