1803 - Robert Hare developed and experimented with the oxy-hydrogen blowpipe 

1826 -   Thomas Drummond discovered that an intense illumination is created when an oxyhydrogen flame is directed at a cylinder of calcium oxide,  which can be raised to white heat without melting. He built the so called "Drummond Light" also calles "Limelight".  This "Drummond Light'' 'can be created with brown's gas and calcium oxide.

1832 - Michael Faraday discovered the laws of Electrolysis. He was able to seperate Hydrogen from water by using electricity.

1875 - The Mysterious Island, Jules Verne in his book wrote of the following age:        

"Water decomposed into its primitive elements, and decomposed doubtless by electricity, which will then have become a powerful and manageable force. Yes, my friends, I believe that water will one day be employed as a fuel".

1962 - William A. Rhodes (USA) is the first inventor known to patent an electrolyzer that produced the simple 'single-ducted' gas we now call Brown's Gas or Hydroxy Gas. In the mid 1960's Mr. Rhodes formed a company (Henes Corp.) with partners who took control of the operation and cut him out. This was a bad mistake, because they did not yet have Mr. Rhodes most efficient design.Henes Corp. eventually failed, went through several hands and was eventually acquired by Dennis McMurray. The company, now named Arizona Hydrogen , is doing well in Phoenix Arizona USA. Watch mr. William A. Rhodes Video.     

            
1974 - Ten years after William Rhodes patents,  Yull Brown   (originally a  Bulgarian Student named Ilya Velbov  1922-1998) from Australia  filed a patent on his design of a Browns Gas  electrolyzer and spent the rest of his life trying to make Brown's Gas a commercial success. He (convinced others) to spent about 30 million dollars and nearly 30 years in this endeavor. Due to his lifelong effort, he is posthumously honored by continuing to call the gas Brown's Gas. Several companies were started, both in cooperation and in competition with Yull Brown. Due to his efforts this variety of hydrogen gas is called (Yull ) Brown's Gas.  

"THE DISCOVERY OF BROWN'S GAS" Born in 1922 in Bulgaria, Yull Brown went to Australia in 1958 as an electrical engineer with a deep belief that Jules Verne’s vision of "There is fire in water", could be realized. He worked as an unknown laboratory technician until he could develop his own laboratory. By 1978 Professor Brown was being described by The Australian Post as "the most talked about inventor in Australia today".

He "discovered" in the early 1970's a proprietary method of water electrolysis that yields a nonexplosive mixture of hydrogen and oxygen gas in the precise atom-to-atom ratio of two volumes of hydrogen to one volume of oxygen. Professor Yull Brown disco vered that hydrogen and oxygen gas can be safely mixed (plus or minus 5 percent) if that ration is strictly maintained.

The result is Brown's Gas, a hydrogen and oxygen mixture that can be economically generated, compressed, and used safely. In Professor Brown's process, the hydrogen and oxygen gases are immediately and intimately mixed at exactly the right ratio (the scientific term is "stoichiometric mix"). Brown's Gas is produced within an electrolysis cell, without membranes and with safety, invented by Professor Brown.
