Flush Before Flying

A Chinese airline is urging people to use the washroom before boarding the plane. A recent study by the airline shows that flushing a toilet at 30,000 feet can use approximately 1 liter of fuel.

(MSNBC)"The energy used in one flush is enough for an economical car to run at least 10 kilometers," Captain Liu Zhiyuan, who flies regularly between Hangzhou and Beijing, was quoted as saying.
