When a competition solicited ideas for what to do with a huge trash-munching power plant soon to be built in his native Copenhagen, Ingels’ studio, BIG, submitted the sort of idea you’d expect from a precocious first-grader: They suggested turning it into an massive artificial ski slope. To the firm’s surprise, the proposal won, and by 2017 or so when the project’s complete, it will no longer seem odd to spend a day skiing on a mountain of trash."
