Running
on fumes
Revolutionary
prototype vehicle aims for 2008 launch

Friday, May 25, 2007
George Parker, president of Fuel
Vapour Tech, stands with prototype car at Victoria airport yesterday.
George Parker has taken the expression "running on fumes" literally,
designing a fuel delivery system that runs on fuel vapours instead of
liquid fuel, allowing him to claim that his prototype vehicle can
achieve an estimated 2.6 litres per 100 kilometres on the highway.
Parker's company, Maple Ridge-based Fuelvapor Technologies, has
designed a three-wheeled vehicle around a turbocharged 1,500 cc
four-cylinder engine that showcases the company's patented fuel vapour
technology. His invention raises the air to fuel ratio, which is
usually 14.7:1 (14.7 parts of air to one part of gasoline) to 20:1,
which helps reduce fuel usage. Parker claims that his invention can
produce as much vapour as the engine needs and will eliminate the
fuel-injection system found in current vehicles.
The Fuelvapour vehicle, called the Ale, does not give up performance to
achieve the high fuel economy. The 180 horsepower Honda engine is
capable of 0-100 km/h acceleration times in the five-second range with
the top end electronically limited to approximately 220 km/h.
Parker also says that the vehicle produces 75 per cent less CO2 than a
conventional engine and does not need a catalytic converter.
The vehicle, which is certified for sale in B.C., can seat two in
tandem. The prototype has motorcycle plates on it.
Parker expects to deliver the first batch of completed cars sometime in
January 2008. The hand-built cars will cost approximately $75,000.
Parker suggests that with mass production, the price can drop to
between $30,000 to $40,000.
Parker is entering the car in the Automotive X-Prize competition. The
California-based foundation behind the competition is looking to
inspire individuals and companies to come up with a super-efficient
vehicle that can be produced.
Parker was in Victoria recently in talks with a Sidney-based company
exploring the possibly of replacing the vehicle's fibreglass body on a
tubular steel frame with one built from carbon fibre.
Switching to the composite material could result in weight savings of
between 30 to 40 per cent, which could result in a smaller engine and
even better fuel economy.
Entrepreneurs and inventors with concept cars touting super-efficiency
are not new, says Lawrence Pitt, a research coordinator with the
Institute of Integrated Energy Systems at the University of Victoria.
"Vehicles offering high fuel economy have sex appeal these days, but it
takes time and an exotic amount of money to bring the concept to
market." says Pitt. While he approaches each new idea with "healthy
skepticism," he points out that all the innovators of the modern
automobile started out in roughly the same way 100 years ago. "There is
always a niche for such cars. The company's success depends on the size
of the niche."

Device
Saves Fuel, Cuts Emissions
A device that could help New Zealanders save fuel and reduce carbon
emissions had its international debut in Queenstown on Monday.
The hydro-charger, a small black box that can be retrofitted to any
internal combustion engine, splits hydrogen from water and uses it to
boost the fuel supply while reducing carbon emissions.
Gary Rovin, managing director of Vision Energy Ltd, the
Queenstown-based private investment company which has New Zealand
distribution and future manufacturing rights for the American
invention, said New Zealand already spent $4.6 billion a year on
imported fossil fuel.
American trials have so far shown fuel savings of an average 12
percent, up to 70 percent, and emission reduction of at least 80 per
cent.
Monday's launch showed the device in action on cars, buses, trucks,
tractors and a generator.
John Dee, from Global Energy Options (GEO) which developed the device,
said he knew of no other company that had used hydrolysis technology to
produce enough hydrogen from a car battery to save fuel as well as cut
emissions.
"We all know from high school science that you can drop a 9V battery in
water and produce bubbles of hydrogen and oxygen. This is the same
thing, but bigger."
Their "secret formula of electrolytes in minute amounts" hugely
increased the amount of hydrogen so produced. This was then introduced
to the engine at the air inlet where, under high pressure, it ignited
and broke up the fuel's long chain hydrocarbons.
This both increased fuel efficiency and cut polluting waste products,
especially big particulates, Mr Dee said. The hydrogen itself also
acted as a fuel.
GEO has a government agreement to supply the hydro-charger to New
Delhi, in a bid to clean up that city's polluted air in the lead-up to
the 2010 Commonwealth Games.
Depending on further field tests and development, the devices could be
commercially available in New Zealand by March, he added.
The price had not yet been determined, as research continued to make
production cheaper, Mr Dee said.
Already, trials had shown the investment would be paid back within a
year.
Canterbury's Drivertek International managing director Bill Frost, who
installed a hydo-charger in his Nissan last Friday, was impressed it
had already shown an almost 10 percent fuel saving.
Queenstown Connectabus owner Ewen McCammon said that even in only 20
hours of trial, both visible and measurable emission levels had
declined significantly.
If proven commercially successful, Vision Energy planned to manufacture
the device in New Zealand, Mr Rovin said.

Necessity,
they say, is a mother
Mark Scott
When gasoline prices topped the $2 level back in 2005, Jack Talbert
dusted off an invention his father had worked on nearly 30 years ago.
"I remembered that my father had made a carburetor that would pre-stage
the fuel by converting it into a gas before it went into the intake
manifold," Talbert said.
By modifying the "fuel blender" device his father once worked on, he is
achieving his goal of beating the pump.
Talbert figures he's getting about 49 miles per gallon, which covers
more than 900 miles of driving and would be considered good with one of
today's tiny hybrid cars. But Talbert isn't driving a hybrid; his car
is a 1981 Oldsmobile Delta 88, with a gas-guzzling 350 V8 engine.
Talbert bought the Olds for $500 specifically for his project.
"I've always preferred big cars," Talbert said. He filled the car's
20-gallon tank in November of 2006 and didn't fill up again until March
of 2007. He was living in his hometown of Abilene at the time.
To fashion the modification, he relied on things he had learned from
his dad, and also from Tom Ogle, a Texas inventor who obtained a patent
for the device in 1977. When George Talbert began experimenting in the
1970s, he used a metal tube, similar to a diving snorkel, and mounted
it on a 1969 Lincoln Continental. The device reportedly increased fuel
efficiency from 12 mpg to about 70 mph. Talbert was five years old at
the time.
"I remember my father couldn't get the hood down, so he left it off
because of that little snorkel sticking up," said Talbert, 39, who
lives in Manhattan.
Talbert began his experimentation by reverse engineering the "fuel
blender." He knew that fuel, like a wood log in a fire, must go through
four known states of matter to complete the cycle. Wood will reach its
flashpoint, and then the outgases will combine with oxygen, leaving
oxidized ashes behind as the process is finished.
Fuel must also reach a particular temperature in order to begin the
reaction. When fuel is in a vapor state the process requires less
energy and heat to conclude. This process is process is called gasoline
vaporization.
"Right now I am the only one I know of that has the vapor converted
car, although it's been done in the past," Talbert said. "I wasn't the
first."
This was not Tablert's first attempt at perfecting the project started
by his father, who passed away in 1982. In 1993 he used it on a 1975
Cadillac, and it worked, even though the engine ran rough, for about
two days. The device eventually was torn up by the stresses under the
hood due to the size of the Caddy's V8 engine.
Talbert said the key to getting the "fuel blender" to work this time
was going with smaller rubber tubing than what had been used by his
predecessors. He used tubing measuring 1/8th of an inch in diameter as
opposed to 2 inches in diameter. He explained that with a larger line,
only the high octane portion of the fuel was being vaporized.
"There is a separate little can under the hood, and fuel is pumped from
the gasoline tank into the can and then the can becomes the fuel
reserve," Talbert said. "Because the can is small and the line in it is
small, then it completely vaporizes whatever is in that can.
Talbert admits that while his Olds Delta 88 gets great gas mileage, it
is hard to drive. It is also slow to accelerate, taking about two
minutes to get up to 55 mph. Therefore, a person driving from Manhattan
to Topeka would want to take U.S. 24, and not I-70.
"You want it to be a straight shot with not a lot of hills," he said.
Fuel is controlled by a plumbing value mounted under the dash on the
right side of the steering wheel.
"My father could never get the car to run and idle," Talbert said. "He
could get it to idle real good, or he could get it to run good, but he
could never get it to do both. By putting a fill control valve in the
fuel line when we need more fuel we just turn the valve up."
Talbert's son, Bruce, a high school student, has been driving the Olds
Delta 88 for about a month. Jack kids Bruce that he has a "lead foot"
and has more problems with the car dying out at stop lights.
Trying to promote his invention, Talbert has consulted with the small
business development department at Washburn University and the
Pottawatomie County Economic Development Corporation.
"Jack is a pretty entrepreneurial fellow," PCEDC director Bob Cole
said. "He needed to know where he can get a technical evaluation of the
device and find investors."
With gasoline prices skyrocketing between $3 and $4 in recent weeks,
why aren't the major car manufacturers jumping at a chance to get
hydrid-like gas mileage with gas-guzzling cars?
Today's cars are mostly port fuel-injected and they have electronic
control modules that govern all the functions.
"It's not that there is a problem using it with port-fuel injection, it
just requires a pressure pump that introduces that vapor into the
cylinder at the right time and right location," Talbert said. "It
literally could be in excess of a million dollars to get to that point.
You could have another $50 million involved in getting it approved, and
you haven't sold one car yet."
Besides, even then the public may not buy it. Talbert noted a survey he
had read reporting that it would take $5 per gallon gasoline before 100
percent of the respondents would make a lifestyle change.

Weston
man claims device can boost car mileage to 500 mpg
Inventor John Weston of Port Charlotte, claims to have invented a
device that can turn virtually any car into a gas-miser that can run as
far as 500 miles on a single gallon. Called the Air Vapor Flow System,
or AVFS, the device functions by vaporizing gasoline before it gets
inducted into the engine. That saves fuel and reduces pollution because
it allows the engine to burn more of the fuel that gets sucked into the
combustion chamber, he contends. The device works on small, industrial
engines or larger automobile engines regardless of whether they have
carburetors or fuel injection systems, according to Weston. The device
consists of a small, plastic tank that gets mounted under the hood of a
car. Some hoses from the engine's air intake housing are run to the top
of the tank so that the engine draws in vapors from above the level of
the liquid gasoline. The device also has some additional features that
affect its efficiency and safety that Weston is not disclosing. In an
impromptu demonstration conducted for this reporter last week, Weston
installed one of the devices into his battered 1992 Geo Storm.
Scientifically, the results can be described as intriguing but
inconclusive. Weston's car ran well on the vapors from the device when
the level of the liquid in the tank was within a certain margin. The
engine ran either too rich or too lean when the level was above or
below that margin. Weston is convinced that the car traveled 14.8 miles
on about 4 ounces of gasoline during the test. If accurate, that would
amount to some 473 miles per gallon. However, an exact measurement was
not obtained due to the testing method. Weston recently tested one of
his AVFS tanks on a gasoline-powered utility generator. Without the
device, the generator ran for 3.5 hours. With the device, it ran for 14
hours on the same amount of fuel, he said. AVFS testing on a small
engine by the firm Adiabatics Inc. in Columbus, Ind. The results showed
it reduced hydrocarbons 71 percent and carbon monoxide 25 percent. The
rate of fuel consumption was reduced by 15 percent to 30 percent. But
the device increased emissions of carbon dioxide 12 percent and
nitrogen oxides 296 percent. Those are greenhouse and smog pollutants.
Weston said those emissions increased because Reg Tech's engineer
failed to properly adjust the vapor/air mixture. "Not all engineers are
mechanics," Weston said.
