Life as we know it needs water. Water has 2.5 times more Hydrogen than gasoline or diesel. Water falls from the sky and comes out of the ground naturally. The Human body is 60% water and the Earth is 70% covered in water. When radio telescopes search for alien life they look for signs of water and start searching there first. Faraday wrote it requires 96Kj of electrical energy to split water into HHO with an increase of 286Kj of heat energy created when Hydrogen is recombined to make water. Gasoline and Diesel are around 90 Octane, but HHO is 130 Octane. Perfect for internal combustion engines, welding torches, Bar-B-Q grills, water purification, and energy generation as it is the only element that gives you more heat output than is needed in electrical input.
