Hydrogen cars have a long history, though not a particularly successful one. Despite a lot of research over many years, hydrogen cars have yet to be produced that are as efficient and environmentally friendly as people would like to see.
Most hydrogen cars utilize the fuel cell conversion principle. Hydrogen is allowed to react with oxygen to produce electricity, which is used to power a traction motor, which in turn is the motive force for the car. This process also produces water, which is a clean and natural waste product.
Hydrogen is not a power source. It is a power carrier, which has to be produced in some way. This is usually by a separate power plant. This is why hydrogen cars are not nearly as environmentally friendly as most people believe them to be.
Today's hydrogen cars actually produce more pollution than conventional cars do. It is not the cars themselves that produce the most of the pollution, but the power plants that are required to produce the hydrogen in the first place. It is the overall pollution levels of hydrogen cars that exceed the overall pollution of conventional cars.
There is also a danger aspect to having hydrogen cars. Carrying large amounts of hydrogen, usually in a compressed form, around in a car is not really very safe. Hydrogen is a highly combustible gas and there have been many serious accidents with it over the years to attest to that.
Hydrogen fuel cells are in fact highly efficient in themselves, but they are costly to produce. They are also fragile by nature and do not lend themselves well to all the vibrations, knocks and bumps that an average car goes through every day.
Additionally, hydrogen fuel cells do not perform well at start up in cold weather. This makes them unsuitable for a significant proportion of the world's land mass. However, research is continuing into this area and the problem may be overcome in time.
One major drawback of having hydrogen cars at this point in time is the lack of refueling points. It is still a specialist area and the vast majority of fuel station can only supply gasoline today. It would take considerable effort and time to replace them all with a hydrogen supply.
Fossil fuels are mainly used today to produce hydrogen. This goes against the current political climate of reducing dependency on fossil fuels. This is also why hydrogen cars are actually more polluting than conventional cars.
However, there is a ray of light on the horizon. It is possible to produce HHO, sometimes known as Brown's Gas, on demand from water through the addition of a simple kit to a standard internal combustion engine. The HHO is burned alongside ordinary gasoline, thereby greatly increasing the mileage per gallon.
Apart from the initial cost of the kit, which is somewhere around $100 to $200, there are no additional costs. One quart, or litre, of water will produce in the region of 1,800 gallons of HHO using a small amount of the electricity in your car's battery. You can double or even treble your normal mileage, at no extra cost. So, why aren't the governments of the world advocating this technology? Who knows!
Cars That Run on Water Tip #1
No matter what anybody tells you, there is not yet a water powered car in production. That is an urban myth that reached its peak with Stanley Meyer who claimed that he drove one hundred miles using only four ounces of water (he was later convicted of fraud). The water powered engine hasn't even been invented yet. Scientists are still trying to figure out if it is even possible. |
Cars That Run on Water Tip #2
Many major car manufacturers are embracing the idea of the hydrogen car. BMW hopes to release a hydrogen car to the public by 2008 (or 2010 at the latest) and other manufacturers like Toyota are also making plans to release hydrogen car lines. Of course the debate over using hydrogen in cars is still raging and nothing has been settled yet. |
Cars That Run on Water Tip #3
While both a water based engine and a hydrogen engine will do wonders for fuel emissions and the environment, one of the major reasons people want them is to improve their fuel mileage. Of course, gas mileage can be improved right now. You can improve your gas mileage drastically just by driving sensibly and making sure your car is maintained properly. |
