And the US automotive industry is in dire straits. It did not learn from the 1973 energy crisis. It did not learn from the Chrysler experience. It did not learn from Toyota. It continued to depend on old, worn out concepts and on CEO’s that are kept in their positions by nepotism and by boards that do not understand the automotive business.
In a joint effort the Big Three are asking the US government for a $25 billion loan. They argue that government demands for increased fuel efficiency are too expensive to implement and require huge amounts of capital for retooling.
Let’s assume for the moment that the argument has some merit. But how can companies with worldwide manufacturing facilities fail to notice the steady increase in fuel prices and not see the warning signs hoisted by governments across the world that want to limit greenhouse gas emissions and fossil fuel consumption. This neglect is inexcusable. Efforts of US and European governments to limit fuel consumption are misdirected, counterproductive, and coercive. A comprehensive analysis quickly reveals that we must indeed limit and eventually halt greenhouse gas emissions.
OPEC countries will continue their unstoppable increases of petroleum prices. Electric cars, CNG powered cars, and hydrogen powered cars cannot stop carbon dioxide emissions perceptibly and will not make our country independent of OPEC imports. Automotive companies are critically dependent on the fickle and changing preferences of national and international markets.
Industrial companies that follow political hype will be punished sooner or later. Governments are incapable of designing automobiles for the market place. The world is relegated to using automobiles, trucks, trains, ships, and airplanes for the next century and will have to power most of them with liquid transportation fuels. We may be able to use less of them, we will be able to reduce energy consumption, we can use other forms of energy for some transportation, and we can produce petroleum substitutes from biomass. We can even produce biomass without competing with critically important food crops.
In order to minimize fuel consumption quickly, the auto industry is forced to deal with performance features. American drivers cannot avoid covering much longer distances than European or Japanese drivers. American drivers have less access to public transportation, have larger families, and drive on different types of roads. Automotive companies must listen to their customers.
Toyota and Honda have been listening most successfully. American and foreign car companies have developed a wide range of comfortable cars with a wide variety of utilitarian and luxury features. Sportive cars and SUV’s are attracting large numbers of buyers. All cars offer a wide selection of comfort and entertainment features. One major car component has received only peripheral attention; it is the much maligned internal combustion engine.
Many modern internal combustion engines are marvels of engineering. Materials, manufacturing processes, and especially peripheral components have progressed to unprecedented levels of performance and longevity. There is a last frontier that has escaped deserved attention. This is the highly energy efficient combustion engine. This is the type of engine that the automotive engine needs to develop, this is the engine that legislators should make mandatory.
This is the engine that we need to use for at least one more century. Long term the automotive industry has to develop an entirely new, advanced, internal combustion engine! Average energy efficiency of the worlds inventory of combustion engines is somewhere in the lower mid-twenties. Energy efficiency cannot grow indefinitely. When approaching the 50% efficiency mark, it will be difficult and very expensive to increase efficiency by a single percent. Advanced automotive engines are operating in the mid-thirties.
Large stationary engines are breaking the 45% mark. Large engines on trains and ships are getting above 40%. Looking at the total world inventory, we may still have a chance to nearly double energy efficiency and to cut energy consumption of present inventory in half. We cannot reach this goal by legislating fuel consumption of cars only. We can achieve optimum energy efficiency only by reengineering the processes taking place within and around the internal combustion space.
We know that higher compression ratios will increase energy efficiency, we know how to produce high octane fuel, we know why Diesel engines are more efficient, we know how to minimize formation of pollutants. The automotive industry has developed a huge selection of sophisticated electronic components for single cylinder fuel injection, for precise controls of valve motion and ignition timing, and for reclaiming waste energy at the exhaust.
No company seems to have found the nerve to get a jump on the competition and develop the successor to the two more than century old engine concepts; the Otto and the Diesel engines. If the US government decides to extend a $25 billion loan to the automotive industry, it should attach a few conditions. The loan needs to be secured and must take precedent over shareholder equity. The loan should stipulate that the salaries of top management are tethered to salaries of other top CEO’s like that of the US President.
The obscene bonuses of yesterday should be paid only after a waiting period of at least five years; in which previously agreed upon management objectives must have been met or exceeded. We must stop the prevalent looting of cash from US manufacturing companies by unscrupulous investors. These investors do not contribute anything of lasting value. They are excessively rewarded for ruining once healthy companies. We cannot continue to let a selected few impoverish the many and ruin our country irreparably.

Have you heard about the latest technology that has caught the attention of environmentalists worldwide? Hydrogen technology is not new and it has been around for many years now. Continuous developments with the technology is being pushed through various governments and institutions because they can see a lot of advantages by using an alternative source of energy like hydrogen fuel.
Currently, converted cars are now using hydrogen fuel. Car engines are typically gasoline powered but with the introduction of hydrogen fuel, car owners can choose between hydrogen fuel and gasoline to power their vehicle.
Here are the advantages of using hydrogen and fuel cells:
- Fuel cells aren’t dangerous. If you frequently surf the net, you’ve probably heard some myths about hydrogen. Fuel cells are easy to operate and are not hazardous. The reason why a lot of people view hydrogen negatively is because of the 1937 zeppelin accident in Hindenburg. The accident was recorded and publicized extensively. That happened many years ago but with today’s advanced hydrogen technology, the use of hydrogen and fuel cells is not something to be scared of.
- Hydrogen provides plenty of energy. Fuel cells are powered with HHO gas and this is similar to water vapor. You will only use water and the HHO generator will do its task. It will separate hydrogen from oxygen molecules. The power of the generator will come from the separated hydrogen. Water is available anywhere, not unless your in a desert, scarcity is not an issue. With the scarcity of oil, it’s no wonder why its price is soaring higher and higher every year.
- Fuel cells require low maintenance. Once your car is converted, you will need to ensure that the quart-sized reservoir has the proper fluid amount. Other than that, you don’t have any other problem.
Gas stations are taking a lot of your hard-earned money. If you want to put an end to this, have your car converted now. Hydrogen powered vehicles are very limited and the purchase of such car is often regulated. Perhaps in the future, hydrogen powered cars will be available to the public and there will be better sources of hydrogen; only then can the price of hydrogen cars be more affordable.
Now that you know that the use of hydrogen and fuel cells is not dangerous, will you have your car converted? This is not a huge problem because all you need are hydrogen fuel car kits or boost kits and you can run your car using hydrogen power. You can definitely improve mileage and you can save a lot of money. Now, you can use the extra money to purchase other more important things.
At present, the source of hydrogen fuel is still under continuous research and studies. Experts are still trying to discover less expensive means of getting usable hydrogen. Although hydrogen makes up a large portion of the atmosphere, most are not in usable form. With studies underway, people can expect that in the future, the planet will be less polluted.
Environmentalists are pushing for the worldwide acceptance of hydrogen and fuel cells. It is up to the different countries now to pursue the use of hydrogen technology. Currently, only rich countries can afford this technology.
Well, who knows; in the future, everything might change.

You can now find hydrogen fuel for your car or cars and experience the many benefits it can provide. Some hydrogen cars are still being tested to prove its efficiency but time will come when these cars will be fully accepted on the road. It would be very beneficial if there are lots of hydrogen stations all over the world; well, who knows… perhaps that time will come too.
The demand for hydrogen fuel for cars will soon increase as the source of hydrogen fuel becomes stable. With the use of hydrogen powered vehicles, you can enjoy driving for about a month without refilling the tank; that’s discrete mileage, right? At present, fully hydrogen powered cars are not yet available.
However, the existing car engines can now be modified and converted. Once modified, the cars can use hydrogen as fuel. By 2010, some car manufacturers are going to launch fully hydrogen powered cars that can answer today’s energy and environmental problems.
With very few hydrogen fuel for cars at the moment, the price is too high for ordinary individuals to afford. But no one can really tell if the hydrogen fuel cars will soon be reasonably priced. At the moment, you can have your vehicle converted so that you can get the feel of driving a hydrogen fuel vehicle. Rest assured that you can save lots of money because you will be using water instead of gasoline. If you want to gain 35-100% increase in mileage, have you car converted the soonest.
Driving conditions differ and this is one thing to consider when using hydrogen fuel vehicles. The car of tomorrow will have an HHO fuel cell. This fuel cell can even be made at home. There are HHO car kits so that you can easily build the fuel cells since the building instructions are included in the kit. If you want, you can also purchase the needed materials and then look for the building instructions online.
How do hydrogen fuel cars work? The process is not hard to understand. Once the car is converted, you can now use clean water as fuel. The water molecules are separated and then the gases are forced into a combustion chamber. In the chamber, the gases are burned and in turn, energy is produced. Now, the car has power and you can enjoy driving for as long you like. Not only is the hydrogen fuel car cost effective, but it is also environment friendly as well. It can reduce pollution and the emission of greenhouse gases.
So, if you want to save the environment and cut-down your gasoline costs, have your vehicle converted now. Well of course, you need to consider if there are hydrogen stations in your locality. Otherwise, you will depend largely on your water source at home. You must know your options before you convert the car. It will involve a certain amount of money and you have to be prepared for it. And when new and fully hydrogen fuel cars are sold for the public, you can buy the car; that is, if you can afford one.
You have to learn more about hydrogen fuel for cars. If you want, you can take advantage of the various resources online and gather the needed information. You have to know how the hydrogen fuel car works so that you can appreciate it even more.
The environment definitely need help nowadays and the hydrogen fuel cars might be of great assistance.
