This carbon-negative vodka is made from captured CO2. 这种负碳伏特加（碳排放为负值，也就是说，生产时产生的碳要低于消耗的碳）是用采集的二氧化碳制成的。 A new brand of vodka from a startup called Air Co. is made from captured CO2 instead of yeast—and making a bottle of it is the equivalent of the daily carbon intake of eight trees. 一家名为Air Co.的创业公司推出了一种新款伏特加，它不是用酵母制成的，而是用采集的二氧化碳制成的，而且生产一瓶伏特加消耗的碳量相当于八棵树每天吸收的碳量。 “Our technology uses carbon dioxide and water along with electricity to create alcohol,” says Stafford Sheehan, an electrochemist and cofounder of the startup, which launched the product in a handful of bars, restaurants, and retailers in New York City today. “我们的技术是用二氧化碳、水和电来生产酒精，”该初创公司联合创始人斯塔福德·希恩说道，他还是一位电化学家。该公司目前在纽约的少量酒吧、餐厅和零售店推出该产品。 “That’s inspired by photosynthesis in nature, where plants breathe in CO2. They take up water, and they use energy in the form of sunlight to make things like sugars and to make other higher-value hydrocarbons, with oxygen as the sole by-product. Same thing with our process: The only by-product is oxygen.” |
