Ulaanbaatar, Mongolia has been rated by Time and other organizations as the most highly polluted capital in the entire world. Because the city experiences such frigid temperatures, residents living in poorly-insulated gers use coal-burning stoves almost constantly, which causes such bad pollution. To help alleviate these conditions, BYU Engineering Capstone students designed a system to better insulate gers, allowing occupants to use electricity to heat and cook. These changes significantly decrease the amount of pollution being produced by coal burning stoves.
