Geek Challenge: Football Stadium Stumper

January's Geek Challenge comes just in time for Super Bowl XLV, where the players on the field won't be the only ones burning energy.  And the excitement of the NFC championchip game that was held in Chicago got us thinking of some football related engineering.

Which football game related activity consumes more energy?

A. NFL stadium lighting for a 3 hour game

B. A field heating system that keeps the field from freezing at 20°F for a 3 hour game

C. Cooking 20,000 hot dogs 

The correct answer with the best engineering content will be this month’s winner. Submit your responses to: geekchallenge@dmcinfo.com
