Get the Best Mileage

 

© Richard Grossman MD, 2008

 

            The cost of gasoline is over four bucks a gallon and diesel is getting close to five—what a horror! So what did I do? I went out and bought a macho four wheel drive turbo diesel truck!

            Can you imagine all the grief that I got from friends about increasing my carbon footprint? Well, most of the time this truck (which already has almost a quarter million miles on its odometer) will stay parked while I drive my Prius. The truck’s former owner told me that it gets 19 miles to the gallon, but I know that a gallon will take the hybrid 52 miles.

            I think that a hybrid is a nice gimmick, but it is not the solution to the petroleum crisis. It is too complicated. Furthermore, there is a lot of lithium in a hybrid’s battery, which is toxic to mine and process.

            The future holds small, efficient vehicles. Europeans have already recognized this. You’ll find Smart cars and similar vehicles everywhere in Europe. The price of gas there is much higher there—over seven dollars a gallon in many countries.

            We have been slow to change our driving habits in the USA. Domestic car manufactures are finally catching on that fuel efficiency is vital, although they have fought this for years. Fortunately, many imported vehicles are quite efficient. My current favorite (not a carefully researched opinion) is the Honda Fit. Two friends have bought these cars and rave about their flexibility and performance. Although it is predicted to get 34 miles to the gallon on the highway, one friend gets over 40!

            There are ways to optimalize your car’s efficiency. You probably know that it is important to check tire pressure every month, but let that gauge rest for several months at a time. Try increasing the pressure two pounds above the recommended level when you finally do check the tires—but not above the maximum pressure on the tires’ sidewall. Buying gas in the morning when it is colder and more dense will get you a few more drops per fill up, but the savings sure won’t make a significant difference.

            Leave jack rabbit starts for the really rich; they significantly reduce mileage. You know to use your air conditioner when necessary rather than leaving the windows open—especially when going fast. The cruise control is also a big saver of gas since it is smoother than most people’s accelerator foot. A gas engine doesn’t need to be warmed up more than a few seconds; any longer is just a waste of fuel.

            My big trick for increasing mileage is to drive so I don’t have to use the brakes—much. I learned this from my driving teacher when I was 16. Whenever you apply the brakes you turn energy into heat and it is wasted. Judicious driving can harvest more of your momentum.

To lay off the brakes safely I leave a little extra space behind the car ahead of mine. That space allows my car to slow down gradually if the one ahead stops, so my momentum is used effectively. I pay attention to the stop lights of vehicles ahead. If one flashes red, I immediately take my foot off the accelerator. Likewise with traffic lights; if I see amber, I start coasting.

Idling is a big fuel waster. One of the tricks my Prius uses to optimalize mileage is to turn off the engine when it is not being used. If you are going to be sitting for more than a minute or so, switch off the ignition.

All of these tricks help to save money. They are also important for the planet’s future. Although we concentrate on the cost of the fuel going into our vehicles, perhaps what comes out of them is even more important. Greenhouse gas emissions released by humans appear to be causing permanent changes to our climate. Storms, floods, forest fires and drought all seem to be worsened by climate change. These natural disasters already have had grave effects on people, but predictions are that the worst is yet to come. It helps that Americans are driving less since the cost of fuel has skyrocketed. Fewer people driving would also help.

What about that diesel-guzzling truck? We bought it to occasionally pull a horse trailer short distances and to share with our neighbors for agricultural work.

Our progeny will appreciate whatever we can do to slow global climate change, including driving less and more efficiently.

BOGO (Buy One, Give One)

“My town has no light,” writes my friend from Ghana. “The high school has no computer. All of us have to travel to Tamale on a rough road for 5 hours to have internet or better education. My parents have never touched a computer.”We all have images of young Abe Lincoln studying by firelight. The reality is that most kids who lack electricity just go to bed after dark. Too few parents can afford to light a lantern so their kids can do their lessons.It is difficult to study and to be productive after dark without artificial light. A recent medical article pointed out that “…1.6 billion people are exposed to adverse health risks because of lack of access to electricity.” Even if there were medicines and the best of doctors living in their towns, they would be useless without electricity for medical instruments and refrigerators to cool medication.Yet two billion people live without a reliable source of electricity. Kerosene is the alternative for many of these people. Kerosene lanterns always present the risk of fire, and they generate air pollution. Their smoke adds to the burden of respiratory disease that afflicts millions.The World Health Organization estimates that indoor air pollution kills 1.6 million people annually in developing countries. That means that one person dies every twenty seconds from smoke from kerosene lights and from cooking and heating fires. Those who do not die from the fumes may suffer permanent damage to their heath. Many of the affected are children, who cannot escape the pollution.Many of the poorest people—the billion who live on the equivalent of just one dollar a day—cannot even afford kerosene. They are doomed to a life of darkness between sunset and dawn.Burning coal and biomass fuels is responsible for much ill health in the poorest countries. When we visited India last winter we watched a woman harvest manure from the sacred cattle. After drying, this biomass was used to cook and heat.Sometimes help comes from unexpected places. An ex-Marine recognized the importance of a safe source of light for people in poor countries and has developed a solar flashlight. How could he get them where they are needed, without a huge grant or government support?BOGO! This stands for “Buy One, Give One.” We’ve had our BogoLight for several months now, and use it frequently. It sits recharging in a sunny window and is ready to go when we are. We take it camping, where it hangs from the top of our tent when we bed down at night and read a bit before sleep. Part of it glows in the dark to help find it for late night pit stops.In bright orange or pink, BogoLights are waterproof, dazzlingly bright and rugged. To order these lights, go to www.bogolight.com. I plan to do some holiday shopping there! You pay $25, which buys your light and the one that goes to a dark country. On the website you can choose what organization gets the gift. My current favorite is Saboba’s Hope, a medical clinic in northern Ghana near where my friend grew up. I recently saw a similar (but inferior) light in a store for more money.Perhaps you have heard of the One Laptop per Child program. It is an educational program to supply robust little computers designed for children in developing countries. They draw so little electricity that the child herself can generate it with a crank. The plan is for each child to have her/his own computer! The specifics are available at www.laptopgiving.org. Although the manufacturer has contracts from the governments of several countries, they are using BOGO to kick-start the program.Hurry if you want one of these gems! They are only available in this country until November 26th—that’s tomorrow. Each order costs $399. Of that, $200 is a tax-deductible donation that pays for the unit that goes to a child in a poor country.These two products, the solar light and simple computer, are both high tech and, at the same time, simple. Each is designed to help people in the developing world, but can fulfill a need in our country. Neither is bankrolled by big money. In each case, the generosity of individuals can help our friends in poorer areas. Remember, two of the most important factors leading to lower birth rates in developing countries are education (especially of girls) and promoting health.© Richard Grossman MD, 2007[The article above may be copied or published but must remain intact, with attribution to the author.
