The Minnesota Vikings unveiled plans earlier this week for their new stadium that will feature the largest clear roof in the world.

Plans are to use ethylene tetrafluoroethylene (ETFE), which is a polymer, not glass. The beauty of this product besides the fact that it will allow natural light into the building? It’s self-cleaning, according to Vikings vice president Lester Bagley.

With rain and moisture, this product is self-cleaning,” Bagley told Bob Sansevere of the St. Paul Pioneer Press.

The roof will also be constructed to handle snow and ice, which is what did in the roof of the Metrodome during the 2010 season when the Vikings were forced to play two home games elsewhere.

“There's a basin that catches the snow and prevents it from going down to the street,” Bagley said. “It slides off the roof into a gutter, essentially, and it breaks up from there. It will be very safe.”

The $975 million project isn’t cheap though. Bracing for the possibility that electronic gambling might not generate enough revenue for the state’s portion of the bill, Gov. Mark Dayton proposed to more than double the tax on cigarettes. According to the Minneapolis Star Tribune, Dayton’s plan calls for the tax per pack of cigarettes to go from $1.23 per pack to $2.83 by July 1.

Whatever it takes to get that fancy clear roof.
