未来的燃料不久可能来自随处可见的资源——人类的排泄物。研究人员找到了将污物转化为生物质原油的方法,使用被称为水热液化的过程制造类似从地下开采石油的物质。美国每日要处理约340亿加仑(约合1.29亿立方米)的污水,能源部西北太平洋国家实验室的科学家称,使用这个系统每年可将这些污水转化为300亿桶石油。 The fuel of the future may soon come from ubiquitous sources - human waste. The researchers found a way to convert dirt into biomass crude, using what is known as hydrothermal liquefaction to create substances that resemble oil from the ground. The United States handles about 34 billion gallons (about 129 million cubic meters) of sewage daily, scientists at the Department of Energy’s Northwest Pacific National Laboratory said using the system could turn the wastewater into 30 billion barrels of oil a year.
