This past June, while many Canadians were beating the summer heat with a quick dip in a pool, a lake or the ocean, Ali Najmabadi was zipping up his parka to ward off the -20C (-4° F) temperatures waiting outside the Summit Station on the Greenland ice sheet. “And that’s their summer,” said Najmabadi with a chuckle.

Ah, balmy Greenland.

So what was Najmabadi, who had finished his undergraduate degree in electrical engineering at McGill University in Montreal just weeks before, doing at the Summit Station, a scientific research center perched atop 3,200 meters (10,500 feet) of ice and nearly 400 kilometers (249 miles) from the nearest point of land? Chaperoning Wendigo, the McGill electrical snowmobile, of course.

Najmabadi  and Wendigo were invited to Greenland based on the latter’s gold medal performance in the Zero Emission category of the Clean Snowmobile Challenge last March. Sponsored by the Society of Automotive Engineers, the competition is designed to test snowmobiles for use in extreme Arctic research conditions.

But Greenland wasn’t a sightseeing junket. Arriving aboard a U.S. Air Force C-130 Hercules transport aircraft, the snowmobile was immediately pressed into service.

The Summit Station is home to the Greenland Environmental Observatory where year-round monitoring of key climate variables is conducted. “The researchers have areas where they take air samples that are about one kilometer away,” said Najmabadi. “The problem is they can’t introduce any pollution, such as emissions from traditional snowmobiles, to those areas because then the samples will be contaminated…This is where the electric snowmobile came in very handy.”

This marks the third time McGill has sent an electric snowmobile to the Summit Station and, since the program’s inception in 2005, the Electric Snowmobile Team has had vehicles recruited to do everything from toting recyclables down from the slopes at the 2009 FIS World Alpine Ski Championship in Val d’Isère, France, to carrying the Olympic torch at the 2010 Winter Games in Whistler, B.C.

According to Cyrille Goldstein, a fourth-year mechanical engineering undergrad at McGill and a member of the Electric Snowmobile Team, the project is a great opportunity for engineering students to apply principles learned in the classroom to a real-life scenario because it provides them with the practical engineering and project management experiences that will greatly benefit them in their future careers.

“It’s an invaluable learning experience because we’re not just copying something that already exists, we’re building new things,” said Goldstein. “We build the lithium ion battery pack from scratch.  We take individual cells and build a case for it, build the structure and design all the wiring and electrical architecture that controls the pack and keeps it safe.

“Anyone on the design team will tell you that the most valuable thing is getting hands-on experience,” said Goldstein “We get to do something that is real.”
