The science or prediction of using water as gas started well over a century ago. In 1874 a French science-fiction author Jules Verne through his series of Les Voyages Extraordinaires predicted the use of hydrogen as an energy source. He also predicted many future modern conveniences and technological inventions such as submarines, airplanes, high rise buildings and helicopters. Almost every one of his predictions has come true, the last but not the least is the use of water-gas or hydrogen as a source of great energy of an intensity which coal will not be capable of. This prediction is coming true in time of great need and desire. At a time that it is most needed when gasoline prices is forcing people in hundreds to give up their treasure automobile and means of transportation because of inability to keep up with rising gas price.

Jules Verne’s water for gas prediction became our reality few years back, now it is exposed to everyone. This means everyone can benefit from this technology to get better gas mileage and save tons of money on gas. No technical knowledge or background is required to install the equipment on your car to start saving money. If you are not comfortable at all installing it, get help or let your mechanic do it for you, it is really simple and easy.

The technology is here and has been proven to work and be the best way to save on high gas prices, there is no other better way to get better gas mileage then running your car on water. A very simple system to put together uses the electricity from your car battery, a few spoons of baking soda, distilled or pure water and a container. This process will convert a gallon of distilled water to approximately 2,000 gallons of hydrogen gas for your car.

The end result of this will be a more powerful automobile that boosts performance while preventing smog. A motor that will last longer and age better overtime, because HHO will remove the carbon deposits and prevent future carbon build up. A quieter and smoother ride, in the combustion chamber HHO burns better than gas and adds more power. Emission of no harmful chemical, the burned HHO turns right back into water making it better for the environment. An incredible gas mileage, more HHO will be burned than gasoline.

Honda is in the fore front of auto manufacturer to introduce hydrogen gas automobile with their FCX Clarity, zero emission from combining hydrogen with oxygen to make electricity. The electricity then powers the electric motor, which in turn propels the vehicle. Water is the only byproduct the FCX Clarity leaves behind. That is exactly what your home made hydrogen car would do. The only difference would be you are using gas on demand while Honda is using compressed hydrogen. You do not run the risk of carrying a compressed gas.

If there's a single issue that has got people around the world apprehensive - it's the astronomical rise in fuel prices. Crude oil that used to cost $27 a barrel hardly 4 years back now costs $140 a barrel. And it could go still higher.

Never has there been a greater necessity for reducing fuel consumption. By doing so, not only would you be doing yourself good by decreasing your expenditure on fuel, you would also be doing the environment a favor by incinerating less fossil fuel.
How do you cut down on your fuel intake without requiring to stop using your vehicle? By keeping to my following six tips, you will cut your fuel expenses by at least 25%.

1. Maintain Your Car
A car that is regularly serviced will require less fuel. Manufacturers of cars suggest a maintenance program. Check yours, and make sure that you follow it meticulously. Get your car checked regularly and get the oil changed at fixed intervals, together with the filter.

2. Avoid Idling The Engine:
A lot of people believe the fallacy that their car engines must idle for some time in winter months so as to get them warm prior to driving. This is incorrect. Simply idling for more than half a minute only wastes fuel. Ten minutes of idling every day means 100 litres of fuel wasted per year. Instead have a block-heater that will heat your car without the negative side effects.

3. Maintain Correct Tire Pressure:
Are the tire pressures proper? See to it that a monthly inspection is carried out. Make sure this is performed when your car is in an idle state, and no one has used it for around 3 hours, at least.
In case your tires are not inflated enough, there is increased rolling resistance. This causes an increase in the load on your car engine, and makes your fuel use to rise. It the pressure comes down by 20%, your fuel usage increases one tenth. You also need to factor the effect of climate on your tire pressure, which has a tendency to differ depending on the temperature.

4. Take of Unwanted Weight:
Don't lug more load in your vehicle than absolutely necessary. Extra load means greater wind resistance, and means more fuel consumed. Whether it's a rack on your car roof or additional luggage, it all means greater gas guzzling.

5. Plan Your Trips:
Scheduling trips beforehand will help combine tips and errands to insure more efficient use of your automobile, and consequently, reduced fuel use.

6. Drive Cleverly:
Your way of driving also dictates how much fuel you consume. Are you a fast driver? Do you gather speed quickly? When you disregard the speed limit, you are, in effect, increasing you fuel bill. Plan beforehand when you need to halt by decreasing you speed in place of braking hard. On top of increasing the fuel used by your vehicle , this may possibly spoil your engine.

7. Assure Yourself Of the perfect Fuel:
Before getting a new car, get to know what its fuel consumption is - this is different from vehicle to vehicle. Which car you buy will impact your gas bill before any other factor.
