Fuel prices are rising like crazy. To you and me, that usually means gasoline. Unfortunately, it’s not as simple as the the evil cartel called OPEC choking the oil stupply. There are also other factors such as fuel refiners’ capacity, huge demand from China, etc. During times like these, as during the Oil Crisis, there is a great interest in alternative fuels. So what are the alternatives to gasoline?
The first thing that would come to mind is diesel. It got a bad rap before for being unreliable, noisy, and dirty. This is unfortunate since diesel is actually much more efficient than gasoline: It can go further per liter. Consequently, it also produces less greenhouse gases. The new generation of diesel engines are even cleaner. This was accomplished by improving the combustion process and by improving the quality of diesel fuel. The good thing about diesel is that you don’t have to wait, it’s here now. In Europe, 40% of the vehicles are diesel powered.
Then there’s the environmentalists’ wet dream: Bio-diesel. Not only is bio-diesel renewable, it is also much cleaner than dinosaur derived diesel (aren’t they also bio?). Bio-diesel is made from a variety of renewable sources: vegetable oil, rapeseed oil, coconut oil, etc. And you can often just pour them directly into the fuel tanks of most diesel engine vehicles without modifications. They will probably be widely use in 5 to 10 years’ time when awareness spreads and production ramps up. That’s about the same time the US leaves Iraq.
Hybrids are a combination of electric vehicles and gasoline vehicles. When running slowly and in stop-and-go traffic, the electric engine is active. When running at high speeds, where gasoline becomes more efficient, the gasoline engine takes over. The battery is automatically charged during braking and when the gasoline engine is active. There are no hybrid diesels yet but it’s only a matter of time before those come out too. Then you can use bio-diesel in hybrids too. They will probably be in widespread use in 5 to 10 years’ time.
Finally there’s fuel cell technology. It is the environmentalists’ thunderous orgasm. The ultimate in forseeable fuel technology. Fuel cell technology is actually an alternative to batteries as a power source for electric vehicles. Batteries have been lagging badly in terms of energy density and the search for a better energy source has led to it. Fuel cells rely on the reaction of hydrogen from the fuel and oxygen from the air to produce electricity and form water vapor, the byproduct. It is the cleanest and most sustainable fuel. It’s is also the most expensive and least viable at this time. My guess is that we can expect widespread fuel cells only in 15 to 20 years’ time.
So what does this mean to us? If you have a gasoline-powered vehicle: nothing much. Just have to keep your vehicle well maintained and drive as fuel-efficiently as possible. If you have a diesel-powered vehicle: use bio-diesels which are being marketed mainly as additives. And of course: WAIT.
to the traffic controller (and others like him) who stuck it out at his post at F. Ortigas cor J. Vargas despite the heavy rain doing what he can to keep traffic flowing. I know some of these guys have reputations for being corrupt and inept (or both) but that doesn’t mean all of them are and the dedication of some, including this guy, is admirable.
to the impatient driver who was shouting out the window like the idiot that he is because he can’t wait his turn at the intersection.
