Under the guidance of teacher
Scott Runkel, a group of Community School middle school students turned
a pretty sorry looking 1981 VW Rabbit into a bio-diesel car.
Students from The Community
School explain how their veggie car works to a group of Hemingway
Elementary students. From left front are Wiley Chubb, Sophia Schwartz,

This past week they visited
Hemingway Elementary showing different classes what they’d accomplished.
That sorry looking car is now decorated with lively slogans and paint,
as well as numerous bumper stickers that say, "Drive Vegetarian."
Using a kit from Greasecar.com,
they placed into the car a Vegetable Oil Conversion System, which allows
diesel vehicles to run on vegetable oil.
Gathered around the car with Terry
Thode’s fourth grade tech class, Kingsley Murphy and his classmates
showed small vials of unfiltered grease. First, he explained, the grease
has to be heated, then filtered to eliminate bits of chicken and French
fries left over from its original fryer use at Atkinsons’ Market in
Ketchum. Then it’s poured into the heated aluminum fuel cell in the
trunk of the car.
Once warmed, a switch is turned
and pre-heated vegetable oil is burned in the engine. By using waste
vegetable oils as fuel, the car will reduce toxic emissions, recycle an
over-abundant waste product, and dramatically reduce fuel costs.
Recently three eighth-graders and
Runkel drove the car to Boise for an Environmental Conference. All went
well until they realized that despite the car getting between 30 to 40
miles per gallon, they didn’t have enough for the drive home. "We had to
improvise," Runkel said.
Taylor Straley and Alisa
Durkheimer picked up the story: The hotel janitor where they were
staying, (name withheld to protect the janitor) heard their story, took
pity and told them about a few restaurants that keep used veggie oil
outside in the alleys in huge barrels. The team scooped some into
cardboard boxes from behind Addie’s, a downtown restaurant on Main
Street.
Then they went to an Albertson’s
store to ask the deli people about large coffee filters, which were
given to them after the tale of woe was related. The cardboard boxes of
grease were decanted into 5-gallon buckets and then into small
trashcans.
"It smelled so bad," the girls
said, together. The trashcans were then placed into a bathtub full of
hot water and the oil was filtered and decanted again into the fuel
drum.
"We were creative about it,"
Taylor said.
Kinglsey, Alisa and Taylor are now
working on receiving a grant from the Christopher Columbus Foundation.
Awarded annually, eight teams of middle school students, from around the
country, who have qualified for the championships in Disney World,
demonstrate projects. The winning team receives a $25,000 Columbus
Foundation Community Grant that helps the team turn its concept into a
feasible solution to a community problem.
"The main obstacle is the car
itself," Taylor and Alisa said. It has problems totally un- related to
the new fuel system. They may need a newer model to use for the
demonstration. If they win the competition in June, The Community School
students intend for the money to go towards outfitting school buses with
the same Greasecar kits.
