The Interrelated Mix of the Measurable Effects of Pollution and Pollution Legislation

A Sea Change... Global Warming

"As the earth rotates on its axis, it is warmed by day as it faces the hot sun and then the temperature drops at night as the surface is cooled by thermal radiation losses into cold space. These temperature oscillations and the nature of the radiation balance were first understood by the French scientist Joseph Fourier. These were further clarified by the British scientist and engineer John Tyndall about 150 years ago when he discovered that CO2 and water vapor acted as [a] radiation barrier that would stop energy losses from the earth, and would retain the energy on the surface of the earth." 1

I remember listening to a radio show on PRI (Public Radio International) where a scientist was viewing data that came from a satellite that measured heat conditions across the surface of the Earth. He did some calculations and found that there were noticeable differences in surface temperatures in areas of the globe that were industrialized. Another scientist was surprised on the air to discover that the human heating systems had a measurable effect on the overall temperature of the planet. Prior to seeing the data he had believed that heating systems had no measurable influence on the temperature of the earth’s atmosphere. My witness of this discovery made me realize some time ago that man’s activities affect the temperature of the planet.

Rising Oceans

"At least one thing was certain. If temperatures climbed a few degrees, as nearly all climate scientists now anticipated, the sea level would rise simply because water expands when heated. This is almost the only thing about global change that can be calculated directly from basic physics.... bring significant everyday problems, and occasional storm-surge catastrophes, to populous coastal areas from New Orleans to Bangladesh. More likely than not, low-lying areas where tens of millions of people live will be obliterated. Entire island nations are at risk. Then it will get worse. Even if greenhouse emissions are controlled and global warming halted, the heat already in the air will work its way gradually deeper into the oceans, so the tides will continue to creep higher, century after century."2 ~The Discovery of Global Warming, Rising Seas

Venice, Italy was thought to be sinking into the sea. A city that was built in Roman times and stayed the same for more than two millennia was suddenly too low in the water to walk the streets at high tide. Venice, we now know, is not sinking. The oceans are rising. What is causing the rise? An increase in greenhouse gasses is causing the rise. The gasses that keep the heat in near the planets surface are growing at a great rate, which doesn’t allow for the temperatures achieved during the day to be dissipated into space at night.

Whose is Producing Pollution? Cars? Farms? Factories?

The arguments about who is causing pollution have subsided. Years of environmental controls have reduced the truly poisonous emissions of most factories. Greenhouse gases have also been reduced significantly as a side effect of these emissions abatement requirements. Today a coal fired power plant emits one tenth the greenhouse gases that an automobile does when measuring their comparative energy output.3 Farm equipment does pollute and is one area of emissions that until this year has avoided regulation. Cars by their sheer volume pollute more than all the other sources combined. "Gasoline and diesel powered vehicles ... emit vast quantities of gases that cause smog and small particle pollution in urban areas. These are two pollutants that EPA has just implicated as major risks to U.S. public health, responsible for the premature deaths of tens of thousands of Americans each year." 9

CAFE’ (Corporate Average Fuel Economy) standards don’t really help. CAFE’ is a series of laws aimed at setting the average fuel economy levels of a particular category of automobile by the Federal government. For example, in 1995 the standards were set at 27.5 miles per gallon (mpg) for cars and 20.7 mpg for light trucks. The idea behind the CAFE’ standards is that when vehicles burn less fuel they produce less pollutants. Unfortunately, CAFE’ standards, though they reduce individual car emissions, can be outdone by the choices people make. "... consumers' current preference for trucks has stopped average fuel economy progress for automobiles and caused combined car/truck average fuel economy to fall from about 26 mpg in 1987 to 24 mpg in 1999."4

Conclusion

As people drive more cars the gains made in reducing emissions for a single car can be erased by the increased number of users, which is what has happened in California. The only solution to California’s smog problem and the United States dependency on foreign oil is to find alternatives that do not pollute as well as allow consumers to choose a vehicle that suits their needs and tastes.

The Enthusiasts

A Spark from the Sky: The Australians Learn to Move with the Sun

"Danish born Adventurer, Hans Thostrup, created the World Solar Challenge. ...The first World Solar Challenge was staged in 1987, with a field of 23 fantastic cars led by the GM Sunraycer which completed the trip with an average speed of 67kmph. ...The 1990 winner was the Biel team from a Swiss Engineering School. ... 1993 saw the 1987 GM Sunraycer record broken. Honda took the honours over Biel, and travelled 803 kilometres in one day." 5

Nothing in this world has ever brought technologists and gear heads so close together than the idea of building the most sophisticated automotive technology needed to make a solar car. The Mecca of solar car test racing is the World Solar Challenge.

Hans Thostrup was a person who believed that the spirit of competition would push the edge of technology further forward. I don’t believe he foresaw the influence his event would have on technology as a whole.

At first only a few universities entered the competition. The World Solar Challenge’s (WSC) first year was the bastion of large corporations, some local Australian universities and the Engineering College of Biel, Switzerland who had also participated. The surprise of the event was that the local universities did so well against world class corporate giants. The instant prestige that the event gave to Australian universities and to Biel pushed other universities around the globe into the fray. In a few short years the large corporate representation that was present at the beginning gave way to universities dominating the WSC.

Lately, the Australian universities, who have been an ever present force in the competition, have regrouped and formed teams made up of several universities. These groups call themselves associations. The best example of this is the Aurora Vehicle Association that won the event in 1999. High school associations have also entered the event and in the early years one such high school group placed near the top, of course it was the United High Schools of Beil, Switzerland association.

Collegiate Electric Formula CART Racing

 photo 0516d007.jpg

Formula Lightning is a spirited, highly visible, electric powered, competition series for Colleges of Engineering student teams. High performance open-wheeled electric race vehicles (top speeds of 143 mph) ... These vehicles raced first in 1994 at the Cleveland CART [Championship Auto Racing Teams] race and since then have participated in venues across the country. 6

The Formula Lightning competitions are based on making the motors and drive train fast and efficient. The cars themselves follow a strict standard to keep costs low and participation high. Though the excitement is high among participating engineering schools, the high degree of standardization has not brought about much innovation. Yet, to see Formula-1 type cars speeding around a race track at speeds of 140 miles per hour certainly does dispel any idea that electric cars are slow and dull. It also demonstrates how schools, when they compete with each other, are virtual hotbeds of innovation.

High Schools, Elementary Schools and Others Chime In

Colleges and universities are not the only ones who have been sparked by competition. High schools, elementary schools and others are all getting into the act. Teachers looking for ways to spark student’s interest have found that competition and project building are very effective ways to demonstrate a direct connection between real life and what is learned in the classroom.

The Electrathon

photo d17089e2-e791-4e5d-b959-dd3a852a816d_zpsaf01b01a.jpg

Electric vehicle competitions began in England in 1978. A group of enthusiasts, encouraged by the development of EV’s formed the UK Electric Vehicle Association. With the help of the Institute of Mechanical Engineers they decided to hold a competition exclusively for electric vehicles. ... All vehicles were supplied with 25 Kg of identical Lucas batteries and the 25 Kg limit is still used today! ... The Lucas Electric Vehicle Endurance Run was born. ... The Electrathon format rewards strategy, skill and common sense, by limiting battery capacity and rewarding endurance. Limited to 64 pounds of battery weight, Electrathons are won by the driver who goes the furthest around a course in one hour. The results are impressive with vehicles typically traveling over 30 miles on a few cents of electricity! ... To enable the average person to build his own design at a lower cost, a simple vehicle design was encouraged.7

Though started in England electric vehicle endurance runs were the fathers to such contests as the World Solar Challenge and Tour de Sol. Both contests grew out of electric vehicle endurance races. Today they are a rage among elementary schools in Canada, Australia and in the Northwestern states of the United States.

Electric Conversions Projects

The idea of taking thousands of dollars of ones hard earned money and thousands of hours of a persons precious time plus the cost of a car that you gut of the engine, gas tank and anything else associated with an internal combustion engine just to make a car run on electricity would indicate to me that there are some people in the market that really, really want electric cars. Now think that there are enough people doing this that an entire industry has grown up around them to supply these people with all they need to do just that, to convert standard cars to electric power. There are literally thousands of electric conversion vehicles on the road; there are probably just as many attempts at converting vehicles to electricity that are unfinished in people’s garages. How do I know this? I know this because in my research I came across web site after web site of classified ads for these vehicles. I found them on eBay. I found parts distributors, parts manufactures and much more. There were companies that specialized in making electric motors for conversions, transmission adapters, motor controllers, switches, gauges, brake compressors, etc. You name it there is a company that has it. There are books on how to do conversions. I bought, "Build Your Own Electric Vehicle," by Bob Brant. There are web sites that display pictorials and diaries of the trials and tribulations of converting a vehicle to electricity. I did a search on Google narrowing the search to "electric vehicle conversion" or "electric car conversion" and I got 3,110 relevant sites. This enthusiasm for electric vehicles convinced me that there is a bigger market for electric vehicles than the major automakers in Detroit would like us to believe. If you want to see an example of what I am talking about go to The Electric Vehicle Photo Album at http://www.evalbum.com/. There you will find many examples of electric conversions as well as parts, and some production vehicles too.

Hand Built Vehicles

Conversions were one thing but hand built vehicles were quite another. There are various backyard tinker built vehicles made of bicycle parts and other objects found around the house. One vehicle grabbed my attention more than all the rest. It was the Robert Q. Riley designed Trimuter, a space ship looking three wheeled vehicle that appeared on the cover of Mechanix Illustrated magazine in February, 1980. The designer’s idea was that an enthusiastic person with a little dexterity, time, tools, money and a garage could purchase plans and build the car from scratch. From the looks of it many people did just that because I have seen these vehicles completely built come up for sale from time to time on EBay and elsewhere. The plans are still available for purchase on Robert Q. Riley’s web site. Go to http://www.rqriley.com/tm.html. The Trimuter just looks out of this world.

The Electric Vehicle Clubs

Another gauge of enthusiasm for alternative vehicles is how many support organizations there are. Let me list just a few groups that support electric vehicles:

I found clubs for steam powered cars, solar powered and hybrid vehicles as well. I did not find clubs or associations for compressed natural gas, (CNG), liquefied natural gas, (LNG), hydrogen, methanol, ethanol or compressed air vehicles. By far the most enthusiasm shown for any type of alternative fueled vehicle, gauged by the number of clubs and associations formed to support ownership, was the electric vehicle.

Conclusion

Alternative forms of personal propulsion have a strong appeal to many people. Not just because it may save the planet from the effects of oil waste. I believe what really motivates people to put such extraordinary efforts in acquiring, converting or hand building electric cars, and for schools the desire to design and build vehicles that push to the outer edges of capacity and efficiency, is that there is a genuine belief that alternative vehicles are the future. The largest group of forward looking individuals believes that the future, in some way, shape or form, is electric.
