This is the unknown history of Professor Yull Brown an inventor of Bulgarian origin.

His baptist name was Ilia Valkov, one of the greatest Bulgarian and world chemists of all time.

and discovers the Brown gas.

The history that we’ll share with you today is one of the most amazing ones, it has all the ingredients to make an action movie script: a hero ahead of time, government repression, spying accusations, the plot developing in different countries, an amazing breakthrough and an unexpected end.

The real name of Yull Brown (Yull Brown) is Ilia Valkov, born at midnight on Easter in 1922 in a small village close to Varna.

From a young age, he is attracted to technology. As a teenager, he served in the Bulgarian Navy in the Aegean Sea.

Later move to Sofia following is electrical engineering studies at Sofia Polytechnic, but after the September 9 coup his life has the first twist, Ilia was sent to a Belene concentration camp (an island in the Danube river next to the city of Belene) in 1948.

He was accused of turning into foreign radio stations (Radio Free Europe) and spying on his own country and declared “enemy of the State“. He served for years in a correctional facility in Bulgaria in horrible conditions.

Later he worked under difficult conditions in the mine at the Labor Educational Dormitory in Pernik. Although a prisoner, during this period his assistance was used to repair important and expensive equipment.

In 1950 he was released but the harassment by Bulgarian secret services didn’t stop, and two years later, in 1952 he escaped from Bulgaria to Turkey passing by the Strandzha mountains and crossing the Rezovo River. In Turkey, he was convicted as a spy and imprisoned for 5 years.

He was released with the help of the US Army intelligence services and the personal involvement of Major Brown, Ilia Valkov took his liberator’s last name, and his first name from Jules Verne that in his book “The Mysterious Island” propose the idea of use water as combustible a kind of inspiration to his life work and fled to Australia in 1956 with a political refugee passport.

In Australia, he graduated from the University of Electrical Engineering in Sydney and began working as an engineer at several large companies in the early 1960s. Yull Brown filed for patents for Brown’s gas in 1974, 10 years after William A. Rhodes filed for similar patents for an HHO electrolysis unit.

Most of Yull Brown’s demonstration was conducted with welding torches where he showed that hydrogen and oxygen could be separated from water and then burned cleanly using many different objects.

In his process, water is separated into its two constituents, hydrogen and oxygen in a way that allows them to be mixed under pressure and burn simultaneously and safely in a 2:1 proportion.

The proprietary process results in a gas containing ionic hydrogen and oxygen in proper mixes which is generated economically and safely and which may be compressed up to 100 psi.

Brown’s Gas is a “cornerstone of a technological edifice” with many commercial and industrial applications.

The gas produced by Yull Brown’s process is a mix of the elements found in water – hydrogen, and oxygen. A mixture of these two gases, normally being highly explosive, is usually considered too dangerous to use.

But combined in exactly the same proportion as they are found in water, the gases can be used and stored together with safety. Hydrogen and oxygen can be separated from water in a proportion that ensures total combustion of the Brown’s gas and requires no regulators for the blending process.

What’s more, used in an implosive system their by-product is pure water vapor – engines powered by Brown’s gas can do the job of the trees by pumping clean water vapor into the atmosphere on a massive scale.

AUTOMOTIVE ENGINE FUEL EXPERIENCE

Yull Brown drove a number of cars on a variety of internal combustion engines, performing many measurements on them using his laboratory fully instrumented dynamometer set-up.

He has been officially monitored to drive 1,000 miles per gallon of water.

The staff of Electronics Australia magazine in 1978 found that the usual internal combustion engine needs very little modification to run on Browns Gas.

The main thing is the removal of the carburetor and its replacement by a pressure reducer and throttle valve. The only other change needed to the engine itself us re-timing to allow for the fact that the hydrogen-oxygen mixture has a higher flame speed that the normal gasoline-air mixture.

There is also a positive improvement in engine life since the only product of combustion is water vapor, leaving no carbon build-up on plugs and valves and no corrosion on the exhaust manifold or muffler due to acid vapors in the gas. The engine runs cooler, due to the absorption of heat by the exhaust water vapor as it expands on exhausting from the cylinders. And there is no pollution. The exhaust feels like warm steam.

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.

That is where he founded his own company Brown Energy and began producing Brown Gas generators. He sold the first to China, where to this day it’s being used to burn radioactive waste.

Browns Gas generators and some of the applications were first developed and manufactured in Australia. Production was transferred to the Peoples Republic of China at the inducement of its government, resulting in mass production of generators for national distribution.

Important Chinese applications, besides welding and brazing, include water desalination, medical and toxic waste management, and destruction, pharmaceutical production applications, and materials hardening.

On August 6, 1992, Prof. Yull Brown made a special demonstration to a team of 5 San Francisco field office observers from the United States Department of Energy.

Cobalt 60 was treated and resulted in a drop of Geiger readings from 1,000 counts to 40 — resulting in the radioactive waste residue of about 0.04 of the original level.

Apprehensive that somehow the radioactivity might have been dispersed into the ambient environment, the official requested the California Department of Health Services to inspect the premises. The health services crew found no radioactivity in the air resulting from this demonstration.

In 1996, the Chinese re-invited Yull Brown to build a Browns Gas system for deployment in automobiles. This particular technology transfer was interrupted in part due to ill health when he decided to return to his homeland, Australia, to spend the last months of his life, and died of heart and kidney failure in a hospital near Sydney, Australia on the 22nd of May 1998. His sole heirs is a daughter he never acknowledged.

What’s so special about his discovery? Brown gas can burn at a temperature of 6000 degrees Celsius – one of the hottest temperatures on Earth.

The gas is composed of hydrogen and oxygen and can be economically generated, compressed and stored. The really cool thing is that the flame regulates its temperature depending on the material being burned. So it’s not always at 6000 C. For that very reason, he believed this gas could clean the world – it could burn any material without harming the planet.

In 2015 in Bulgaria was held a contest to find the “Top 10 Wonders of Bulgarian Science” in that contest the discovery of Brown Gas by Yull Brown (Ilia Valkov) was ranked in the 3rd place by public vote.

If Brown gas will change the world is still to prove, but Yull Brown had been an inspiration to hundreds of scientists from all over the world that are looking for cleaner and more economical sources of energy for our planet.
