But we don't have a lot of time, and I'd like to show you the artist's conception of how this system might look if we find ourselves in a protected bay somewhere in the world, and we have in the background in this image, the waste water treatment plant and a source of flue gas for the CO2, but when you do the economics of this system, you find that in fact it will be difficult to make it work.
但我们时间不多，我要给你们看的是 这看起来像是艺术家的构想， 在一个受保护的海湾 在某个地方，想象中我们的背景是 污水处理场 和排放CO2的管道， 但当你考虑到这个系统的经济因素， 你会发现这个很难运作的。
