Shocking Science: UAF engineers create award winning electric snowmachine

Despite the cold March weather, the UAF ME Clean Snowmachine Team brought the heat at the Society of Automobile Engineers’ “Zero Emission” Snowmachine competition this year.
The competition was held in Michigan, and consisted of four teams: Michigan Tech, South Dakota School of Mines and Tech, UAF and McGill University.
The team consisted
of Christin Davis, Isaac Thompson, Ben Neubauer, Karlin Swearingen, Russell Carroll, Craig McKenzie, Amanda Mertes, Adam Burnett and advisor Michael Golub.
The team won nine out of 12 events and
took first place in the overall competition.
“It took us a year to make the machine,”
Thompson said. “Its MSRP is valued at about $17,000 .” The team was disqualified from the distance event due to an engine mishap.
“During the noise competition the throttle was held wide open,” Thompson said. “Since the rev limiter is on a one second delay it can be bypassed by holding the throttle open. So the engine kept revving up and it shorted out.”
The team was able to ship a spare motor overnight to the competition.
The team was then disqualified from the distance event because of the newly replaced engine.
The snowmachine has a peak horsepower of one hundred, can reach a top speed of 70 miles an hour, and weighs 580 pounds.
“A regular snowmachine weighs around 540 pounds,” Neubauer said. “With a little more time we can get our machine there.”
“With the battery at three quarter of a charge it went sixteen miles, It could easily get to twenty with a full charge,” Thompson said.
Even with all this power, the machine has a zero emission rate, makes little to no
noise and runs off nothing but battery power.
“You have to be careful when you’re riding the snowmachine, it has more power then you think,”
Swearingen said. “One time I was driving it around, I pushed on the throttle too fast and nearly flipped it.”
Because of the team’s sweeping victory, the National Science Foundation asked the team to bring the snowmachine to Greenland for emission research. The team and the electric snowmachine will
help researchers come up with new ways to efficiently travel between research stations without fear of emissions ruining data at the stations.

“If we get the money to do this again,” Thompson said. “We can build an even better one, maybe we could even try it out at Arctic Man, if someone was brave enough to drive it.”
