Abstract

Fuels are any materials that store potential energy in forms that can be practicably released and used for work or as heat energy

Fuel

HistoryThe first known use of fuel was the combustion of wood or sticks by Homo erectus near 2,000,000 (two million) years ago.

PETROLEUM CONSUMPTION PER DAY8,76,00,000 Barrels of petroleum used per day733.33 litres of petroleum used by a person per yearAs per estimated values by survey the world can go with petroleum for the next 47 years only.

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.

Simple separation of hydrogen from water

Advantages1. Most abundant element:Hydrogen is the most abundant element in the Universe, which makes up about 3/4 of all matter. Anywhere there is water (H2O) you have hydrogen and oxygen.

2. Hydrogen has the highest energy content:Energy content of hydrogen is the highest per unit of weight of any fuel. Therefore it offers the most “bang for the buck”. When water is broken down into HHO, otherwise known as oxyhydrogen or Brown’s Gas, it becomes a very, very efficient fuel.

3. Hydrogen is non-polluting:Along with its effectiveness as a fuel, hydrogen is non-polluting. The only byproduct of hydrogen when it burns is heat and water.

4. Hydrogen is a renewable fuel source:Hydrogen is very plentiful. The trick is to break the water molecules down to release it.

5. Reduce dependency on foreign oil:It will greatly reduce the import of highly expensive oil demands of our country.

Disadvantages1. Hydrogen is currently very expensive, not because it is rare (it’s the most

common element in the universe!) but because it’s difficult to generate, handle, and store, requiring bulky and heavy tanks like those for compressed natural gas (CNG) or complex insulating bottles if stored as a cryogenic (super-cold) liquid like liquefied natural gas (LNG).

2. It can also be stored at moderate temperatures and pressures in a tank containing a metal-hydride absorber or carbon absorber, though these are currently very expensive.
