Winter is bearing down anew, and Harvard University students have been engineering new ways to deal with it.
 
Eighteen juniors representing several engineering disciplines in professor David Mooney's problem-solving and design class spent the fall semester inventing a robotic remote-control rooftop snowblower, a superheated icicle cutter and a freeze-resistant doormat.
 
The projects grew out of meetings with the university's Facilities Maintenance Operations department, which is responsible for clearing snow from the 5,000-acre campus and was particularly challenged last winter when the Boston area got more than 9 feet of snow. Harvard shut down several times, the first time campus closed since the infamous Blizzard of '78.
 
"Don't get me wrong, FMO did an impressive job last winter," electrical engineering major Peyton Fine said. "But we wanted to somehow improve their operations. We wanted to make it easier to get around campus safely and keep workers safe."
 
A major problem is clearing snow off Harvard's many old and flat-roofed buildings. The main Cambridge/Boston campus has about 500 buildings.
 
The students retrofitted a commercial snowblower that can be controlled using a modified video game control pad and can be operated remotely, even from inside a nice, warm office. It eliminates the need for workers to spend time on slippery rooftops where they risk falling.
 
Another potential hazard for workers is clearing icicles off eaves. The students' research found that about 150 people a year are killed in the U.S. trying to clear snow and icicles off rooftops.
 
For that problem, the students came up with a device resembling a roof rake, with a long handle topped with a Y-shaped head that holds a super-heated wire that can quickly slice through the thickest of icicles while the operator stands on firm ground.
 
The students also developed a durable freeze-resistant hydrogel mat to keep doorways and steps ice free.
 
The class was one of the most practical junior bioengineering major Cassie Lowell has taken.
 
"It's a unique class in the sense is that we're given a lot of freedom," she said. "It was a really hands-on, real-world experience."
 
The students and Mooney stress that all their inventions are prototypes and won't be deployed on campus this winter. But some of the students plan to keep working on them, with the goal of one day making them commercially available.
 
Fine said he'd love to walk into a hardware store in the future and see the items for sale.
 
"Just like someone has a leaf blower in their garage, we'd love to see someone have an icicle cutter in the garage one day," he said.

    These problems are more relevant for Harvard students than students at the University of Miami because Miami is closer to the equator and does not receive snow due to the heat.

    It is more relevant for Harvard because they live farther up north.

    These problems are more relevant for Harvard students other than Miami students because the climate is different.

    These problems are more relevant for Harvard students than students of the University of Miami because there is high temperatures in Miami because it is so far south.

    The problems are more relevant for Harvard student because it is cold constantly were they live, and the buildings are flat roofed.

    These problems are more relevant for Harvard students than students at the University of Miami because they've created multiple items to get rid of the troubles from the snow such as icicles.

    These problems are more relevant to Harvard students than the University of Miami because Miami doesn't get that much snow, and if it does get snow, it melts quickly. Harvard, however, got 9 feet of snow last year. That's enough to bury a worlds tallest man, then some.

    These problems for Harvard students are more relevant than to those students at the University of Miami because in Harvard it gets really cold and they have to worry about how to get the icicles from the roof. Rather than, Miami is much more hotter due to them being in the south.

    The problems are more relevant for Harvard students than students in Miami because of the location. Miami is warmer, and they have no snow there, while Harvard is farther north, and much colder, and they get more snow.

    These problems are more relevant for Harvard students rather than students at the University of Miami because where Miami located in the south it doesn't receive.
