Is Hydrogen a Safe Fuel, Or Not?
Is Hydrogen a Safe Fuel, Or Not? How dangerous is hydrogen, lets compare. We all know how dangerous gasoline is. You drop a match on spilled fluid it explodes. Diesel is not as bad as its flash point is a little higher. You can actually hold a match to diesel and light it, although I would not recommend it, the reason for this is the flash point. Gasoline flash point is 536 degrees Fahrenheit where as diesel is 489 degrees Fahrenheit. Hydrogen flash point is almost double that of gasoline or 932 degrees Fahrenheit. Flash point is defined as, lowest temperature at which a liquid can vaporize to form an ignitable mixture in air. So in other words, hydrogen has to be heated a lot higher than gasoline to ignite. Hydrogen gas is also lighter then air, in fact it is 15 times lighter. So if a leak did occur, the hydrogen gas would rise, it would than combine with air and quickly become so sparse that it could not burn. If by a small chance ignition did occur, being lighter than air it would burn upwards and be consumed quickly. Gasoline and diesel vapors on the other hand are heavier than air and will not disperse but will follow the contour of the ground. If ignited it would spread rapidly. These vapors also have a lower ignition temperature so the chance of ignition is greater. With gasoline you also have a larger chance of an explosion. Petroleum products are poisonous to humans and considered asphyxiates Hydrogen is actually a naturally occurring element and is non toxic. Petroleum products produce CO2 which is expelled into the air, while hydrogen produces O2. This is why when you leave a car running in a closed garage it could cause your death. This death is caused by too much carbon dioxide entering your body. It triggers your brain to speed up your breathing to get rid of excess CO2. Too much CO2 changes acid level in the body and in turns causes your death. When pure hydrogen and pure oxygen is burned only pure water is produced. So when hydrogen is introduced into an engine it actually cleans the ambient air by burning the excess hydrocarbon. By burning the excess hydrocarbon you start pushing oxygen instead of carbon dioxide out your tail pipe. With oxygen coming out our tail pipe instead of carbon dioxide, what do you think that it is going to do to our environment? In comparison petroleum products produces carbon monoxide, nitrogen oxides and hydrogen sulfide. None of which is good for the environment. As you can see introducing hydrogen into the fuel really helps in cleaning up our environment and as a bonus it will increase your fuel mileage. Fuel mileage increases from burning more of the fuel that enters your engine. The more fueled burned the less fuel is wasted out the tail pipes. With all these factors taken in consideration, hydrogen fuel is a pretty safe fuel and better for the environment when used correctly. Just remember, as with any other fuel if used incorrectly it can and will be dangerous. This is especially true in a closed area. But used correctly you not only will be able to increase our mileage you will also help save our air quality.
Hydrogen Car: The Answer To High Gasoline Prices?
The recent rise in gasoline prices have given people more reason to look for alternative means of transportation. The rising cost of using gas may have motivated a lot of people to clamor for an alternative form of transportation that would help usher in an age where humans no longer have to depend a lot on a so-called Oil Economy.
And with the move to look for alternative sources of transportation, many researchers have begun looking into other forms of alternative fuels in order to run future vehicles. One of the most attractive and in fact the most appealing concept provided is the use of hydrogen to run cars. It would only be time before hydrogen cars would be used as the primary transport in the streets. Btu what exactly is it?
A hydrogen car is a relatively new type of transport vehicle that uses hydrogen as its primary on-board fuel. The hydrogen car is different from conventional vehicles in that it uses a different type of engine to make the vehicle move. There are two ways that this can be made possible.
There is one type of hydrogen car can be powered by the burning of hydrogen fuel, much like what happens with a gasoline engine. The hydrogen engine is actually a modified version of the traditional gasoline internal combustion engine. The process used in running both may generally be the same- the force of burning hydrogen provides the explosive power that makes the engine produce mechanical power to make the car move.
A noticeable benefit that a hydrogen powered vehicle provides is that it makes use of a cleaner fuel source for power. This means that using hydrogen as fuel allows lesser polluting substances and chemicals being emitted into the atmosphere. In fact, the hydrogen car concept has been realized because researchers have been looking for a cleaner alternative fuel to be used in the future to replace crude oil. And apparently, hydrogen fits the bill quite nicely.
Another type of hydrogen car being develop today makes use of the hydrogen fuel cell for power instead of a specialized internal combustion engine. In this set-up, the hydrogen is used to provide and generate electrical power that can be used to run the car’s electric motor. This way emissions are totally avoided unlike a car using an internal combustion engine (ICE) running on hydrogen.
Although the use of hydrogen fuel cells is being eyed to have the best potential to power hydrogen cars of the future, the plan may still face certain obstacles. One, hydrogen fuel cells are too expensive to produce using current technology. Not only that, hydrogen fuel cells also tend to be very fragile and sensitive to vibrations and sudden movements.
Engineers today are still trying to come up with a design and develop a type of hydrogen fuel cell that can be strong enough to withstand the vibrations frequent bumps that normally comes with traveling by car. And at the same time, there would be a need for a better and more affordable technology to build the hydrogen fuel cells to make them more affordable to consumers.
But despite the challenges still posed on the development of the hydrogen car, its future still remains very bright. What especially makes hydrogen cars so attractive is that hydrogen is a renewable energy resource. This is unlike fossil fuels which will run out sooner or later and may cause even more serious rise in gasoline prices. The hydrogen car proves to be a more logical alternative to a world looking for a means to move away from too much dependence on fossil fuel.

Hydrogen Powered Cars
Hydrogen powered cars is the hottest technology to save the gas and fuel. With the recent increase in gas prices and the many environmental problems that have arisen, the need for a car that will not use gas. In an effort to lower the cost of gasoline and reduce the many car emissions ruining out atmosphere, scientists have come up with a car that is ecologically friendly and can be run without the use of fuel.
This car modification will give your car a whole new life; these hydrogen-powered cars can be had or created using a system. The system started out by turning a car into a hydrogen car using the HHO Car Modification system, which allowed the person to convert their vehicle into water driven car. The modification will save the person over 20% of the cost they would spend on fuel.
The conversion is easily accomplished by using the battery in your car to change the water into fuel that can be used to reduce the amount of mileage you put on your car, it also burns a lot cleaner than gas, which results in lower car emissions. Buying a conversion unit will cost a lot of money, however it will virtually pay for itself in the long run by saving you money on gas prices.
Another type of Hydrogen car was designed by a lab in Los Alamos, by technicians on a hunt for a car that would offer zero emissions and keep the fossil fuel cars of today from releasing harmful pollutants that escape from these cars. By creating these cars, manufacturers. These cars use hydrogen cells that are replacing the gasoline powered internal combustion engines and turning it into hydrogen powered combustion engine. These new engines will revolutionize the car industry and save the environment for out children.
Hydrogen modified cars and hydrogen powered combustion engines are the wave of the future, open up doors to a cleaner environment and less gas consumption, saving natural resources for other uses. It is the hope of scientist that these hydrogen-powered cars will completely replace the gasoline-powered car in the near future.
Many manufacturers are now making a type of hydrogen cars that are well designed and saves the auto owner tons of money on gas prices. Companies such as Volkswagen, Toyota, Think, Suzuki, Renault, Nissan, Mercedes, and many others have created their own version of the hydrogen car. These manufactures have stepped up to aid the Environmental Protection Agency in their fight to eliminate the use of fossil fuels and to clean up the pollution created by these vehicles and to cut down on the rising costs of these gas products.
If you are ecologically minded and would like to make the earth a cleaner, safer environment for your children, or you just want to stop paying so much of your hard earned money on the rising costs of gasoline, you will want to invest in a hydrogen powered car conversion kit and say good by to emissions. While this product is far from popular, the future of the world is the hydrogen cars.
