A quick video to demonstrate the combustible heavier than air constituent of BG (HHO) and the three phases of combustion; explosion, steam/pressure, condensation/vacuum.
This video demonstrates:
1. How I use water displacement to assure that the bottles contain nothing but pure Brown's Gas at United States - Standard Temperature and Pressure (US-STP).
2. That Brown's Gas (HHO) contains combustible heavier than air constituent(s) by showing, after as long as 10 minutes, an upright open bottle still contains a combustible gas.
Hydrogen is MUCH lighter than air and escapes any open bottle in seconds. Ask any scientist how long hydrogen would remain in an open bottle. The hydrogen escapes at least as quickly as the bottle initially fills with water.
The reason I use a bottle with a narrow neck, for this demonstration, is to slow down the diffussion of air into the bottle (air that mixes with and gradually carries away the heavier than air gasses) not to slow down the escape of the hydrogen.
3. You can see the 'ring of fire' that I've described in the past. This demonstrates not only a 'rolling donut' of flame but that 'open air' combustion of these 'heavier than air' constituents is fairly slow; not the detonation you get from a US-STP stochiometric mixture of hydrogen and oxygen (one of the most powerful explosions short of nuclear).
4. See that 'closed bottle' combustion of the 'heavier than air' components results in a 'ping' (instead of a BANG) and the gases condense to water.
My theory is that Brown's Gas contains a special form of water that I call 'Electrically Expanded Water' (ExW). This form of water would normally be lighter than air BUT it acts like a 'glue' to allow additional hydrogen and oxygen atoms to cluster into what Ruggero Santilli calls 'magnecules', which are heavier than air. The ER50 allows you to demonstrate this combustible constituent of BG (HHO).
5. That a pop bottle can contain the pressures and temperatures resulting from a pure BG explosion, when the initial BG is at US-STP.
6. That there are three phases of BG (HHO) combustion;
Knowing how the characteristics of these three phases of combustion helps to design fun and practical applications for Brown's Gas. Like 'fireworks' or bottle rocket fuel or water bottle rocket canon fuel or fuel for internal combustion...
Currently I'm participating in a collaboration to use BG as a fuel for a pistonless water pump. You need to really understand BG combustion characteristics to design a pump that efficiently uses BG as a fuel.
