How Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of

Advantages and Disadvantages of Renewable Fuels Solar Energy: Advantages: -Energy is free although there is a building cost. -Causes no pollution‚ however‚ energy may go into machines that produce pollution. -Solar energy can be used in remote areas where it is too expensive to extend the electricity power grid. -Estimated that the worlds oil reserves will last for 30-40 years whereas solar energy is infinite. Disadvantages: -Solar energy can only be harnessed when it is daytime

Fuel From Plastic Waste Introduction: Household items made of various kinds of plastic. Plastic is the general common term for a wide range of synthetic or semisynthetic organic amorphous solid materials used in the manufacture of industrial products. Plastics are typically polymers of high molecular mass‚ and may contain other substances to improve performance and/or reduce costs. Monomers of Plastic are either natural or synthetic organic compounds. The word is derived from the Greek
