尿液对于身体来说是废物，但对社会来说，它也可能成为重要的资源，尼日利亚的一个由三个学生组成的发明小组这样报道。他们研发了一种用尿液产生燃料的系统。他们通过分解尿液中的水来获取氢和氧。氢是一种强大的能源。它清洁且易于获得，这几位青少年指出。
To the body, urine is a waste. But to society, it could be a major resource, reports a trio of student inventors from Nigeria. They developed a system to produce fuel from urine. They do this by breaking down the water in urine to get hydrogen and oxygen. That hydrogen is a powerful source of energy. It＇s also clean and readily available, the teens note.
