Alternative Vehicles: Myths and Misconceptions
By Ned Ryan Doyle
|
For most folks “Alternative Vehicle”
conjures up the image of a futuristic contraption dramatically
different from today’s cars and trucks. That’s a misconception;
there’s nothing significantly strange or unique about the
vehicles themselves, it’s the fuels that are ‘alternative’.
The overwhelming majority of engines today run on either gasoline
or diesel fuel. Bio-diesel, ethanol, methanol, compressed natural
gas (CNG), electric and electric hybrids, hydrogen, wood gas,
propane, methane and fuel cell vehicles combined make up less
than an estimated one percent of all vehicles on the road. This
severely unbalanced ratio is a testament to the power of the oil
industry. The reliance on fossil fuels for transportation is a
major contributor to environmental pollution, disturbed weather
patterns, our economic instability and why we go to war to control
oil supplies.
A current ad campaign for an auto manufacturer applauds the vision
and creativity of Henry Ford, while subliminally supporting the
myth that his cars always ran on gas or diesel. In truth, Henry
Ford was the first vocal proponent of an ‘alternative’
fuel: ethanol. He preferred grain-produced ethanol fuel for his
cars, not because the engines ran better (they do), and not because
ethanol is nearly pollution-free (it offers spectacular reductions
in emissions), but because he believed in the economic benefits
of supporting the larger community by having farmers make ethanol
fuel. He did feel his cars should be affordable to all, as the
ads proclaim, but he also believed that the economic benefits
should be shared by all the people, not just a handful of industry
CEO’s. He lost the debate then, but Henry Ford’s arguments
are as persuasive, well reasoned, and logical today as they were
one hundred years ago.
Rudolph Diesel introduced his new, spark-less engine in 1900 in
Paris, France. His new invention, the diesel engine, ran on…
peanut oil. Yes, Rudolph Diesel also used an ‘alternate’
fuel over one hundred years ago. Today, running a diesel engine
on bio-diesel fuel offers significant reductions in emissions
in existing vehicles. The ongoing development of high efficiency
diesel engines suggests that future bio-diesel engines will be
dramatically cleaner. In addition, the same arguments for supporting
local farmers with the production of soybeans other crops for
bio-diesel holds true.
Other liquid and gaseous fuels, such as methanol, methane, CNG,
hydrogen and so on, are little more than variations on ethanol
and bio-diesel, at least from an engine’s perspective. For
example, a gas engine is designed to vaporize gasoline and then
ignite it with a spark.
Converting to a compressed gas, like methane from hog waste lagoons
or landfill reclamation projects, simply eliminates the need for
a carburetor because the compressed gas vaporizes naturally when
released from its storage tank.
Electric and hybrid electric vehicles are commonly misconstrued
as ‘alternative’, but in fact they too have a long
history. In a nutshell, electric vehicles are virtually pollution-free
in terms of operation, but their electricity needs to be generated
from some source. Unless the electricity is generated from clean,
renewable sources such as direct solar, wind power or bio-fuels,
the advantages of electric vehicles are diminished proportionally.
Hybrid electric vehicles that charge their own batteries, like
the Honda Insight and Toyota Prius, are unquestionably more efficient
than conventional cars and a major step in the right direction.
However, until they too operate on renewable fuels, they’ll
simply extend the diminishing supplies of very profitable fossil
fuels.
The newest ‘alternative’ myth is that of fuel cell
technology. Against all logic, the government is pumping billions
of scarce taxpayer dollars into a handful of private companies
doing fuel cell ‘research’. What makes it so illogical,
from environmental and economic standpoints, is that the fuel
cell technology being promoted will run on fossil fuels. Fuel
cells make sense and are environmentally positive if fueled by
solar or wind generated hydrogen, for example, but make little
sense if fueled by LP, coal gas or other fossil fuel hydrocarbons.
Fuel cells will extend our dwindling oil reserves, which means
prices and profits can continue to rise, but what all living beings
on this planet need is to stop squandering fossil fuels altogether,
not keep burning them until the final drop is gone.
It doesn’t require a degree in combustion engineering to
understand that the notion of ‘alternative vehicles’
is a myth. Anyone with a reasonable dose of common sense can figure
out it’s the fuel, not the vehicle, that is the ‘alternate’
issue. Sadly, common sense in the United States seems to be as
endangered as many species. Fortunately, a growing minority of
Americans are waking up to the realization that we must change
our oil dependant system, that we do indeed have much better alternatives
and that the future of our children – and theirs –
rests precariously in our hands today.
