"Many people do not realize that when you run a car or truck on gasoline of diesel fuel, you are actually running it on hydrogen. And all we are doing is using the hydrogen from water. Safest gas on the planet, because there is no fumes. And under the National Bureau of Standards figures shows that when you use water, the energy release is roughly two and a half times more powerful then that of gasoline. So water is a very powerful fuel." Stan Meyers 1992"
"Hydrogen and Oxygen gas spilt from water, we can "Hydroxy gas"
the molecules are bonded together positively in a ortho hydrogen state,
2.4x's to 4x's more powerful than the normal "para hydrogen""
"By splitting water by electrolysis and creating hydrogen/oxygen gas, you can replace gasoline."
"You never hear much of this, expect for Nasa with rockets."

"At room temperature ordinary hydrogen consists of about 75% ortho and 25% para form. As the temperature is lowered, the equilibrium shifts in favour of para hydrogen. At 25K. There is 99% para and 1% ortho hydrogen. The change in the proportion of the two forms of hydrogen requires a catalyst such as platinum or atomic hydrogen or silent electric discharge."

"Because hydrogen is different from gas, the sorts of air-fuel ratios, compression ratios, timing and ignition energies you can run are wildly different from what you'd normally see. For example, you can run an air-fuel ratio as lean as 180:1, and a much higher compression ratio since hydrogen has a higher octane rating."

"In a fuel cell, hydrogen (H2) gas from the vehicle’s fuel tank combines with oxygen (O2) from the air"

"Brown's Gas, often referred to as HHO, is 2 parts hydrogen gas, and one part oxygen gas (by volume)."
"What makes Brown's gas unique, and much more valuable, is that the hydrogen and oxygen have not formed into H2 and 02 molecules. They are in their monatomic (one atom per molecule) state. In this state, 3.8 times more energy will be returned when the hydrogen burns (combines with oxygen)."
"Brown's gas is best provided in an on-demand system."

"injects the hydrogen directly into the car’s air intake manifold (similar to nitrous oxide injection) to be combusted in the engine’s cylinders rather than converting the hydrogen’s energy into electricity to spin electric motors like a fuel cell. BMW says this is a more efficient use of the hydrogen"

"Hydrogen is an increasingly popular energy carrier. It can be readily produced from water using renewable electricity, and it burns without any greenhouse gas emissions. It is colorless, odorless, and does not spill. It’s no wonder there is a great interest in hydrogen engines as a part of destination zero."
"Using hydrogen to power an engine or motor is more straight forward than you might think. There are two ways to do this.
The first way involves a device known as a fuel cell. The fuel cell converts hydrogen to electricity, which then powers the vehicle’s electric motors, just like in any electric vehicle.
The other way is hydrogen engines; internal combustion engines that burn hydrogen as the fuel. Either method has its advantages and applications where they are best suited. However, the latter, using internal combustion engines is a more familiar technology.
In fact, one of the very first internal combustion engines ran on a mixture of hydrogen and oxygen—and featured an electric spark ignition mechanism"

"Hydrogen has been used to fuel vehicles for decades; way back in 1807, Francois Isaac de Rivaz designed the first hydrogen-fueled internal combustion engine, and century and a half later, scientist Roger Billings converted the engine of a Ford Model A to run on hydrogen. Fast forward a little, and hydrogen is being used to send NASA rockets into space."
