//while working on a competition problem involving the Colorado River Lev: Wait, can we call the Hoover Dam? //later, when still unable to reconcile theoretical power output with actual power output (he calculated 120% efficiency) Lev: I think it's because the dam isn't running at full efficiency all day. Like, it doesn't run 24/7. At night and stuff, they turn it down-- Shirley: But that would make your calculations worse! Lev: No, it would make the left side bigger...oh wait, it would. Shirley: 200% efficiency! Lev: Maybe it operates more than 24/7.
