What is most remarkable about what they are doing is that instead of trying to re-engineer the global economy----as is required, for example, for the use of hydrogen fuel----they are trying to make a product that is interchangeable with oil. The company claims that this “Oil 2.0” will not only be renewable but also carbon negative----meaning that the carbon it emits will be less than that sucked from the atmosphere by the raw materials from which it is made.
【正确答案】：他们所做的事最引人瞩目之处在于，他们不是像人们在采用氢燃料时所期望的那样要重振全球经济，而是力图制造一种可以与石油互换的产品。这家公司声称，这种“第二代石油”将不仅是可再生的，而且是负碳的----它排放的碳要少于它的原材料从大气中所吸收的碳。
