In some of these areas, there's not enough water, there's no energy, it's going to cost tens of trillions of dollars to lay out the sewer lines and to build the facilities and to operate and maintain these systems, and if you don't build it right, you're going to have flush toilets that basically go straight into the river, just like what's happening in many cities in the developing world.
在上述的某些地区，没有足够的水， 也没有能源， 为了修建这些抽水马桶将要花费数十万亿的美元 去铺设排污管道 和建设这些设施 以及运营和维护这些系统， 并且如果你不能正确的修建它的话， 那么你的抽水马桶 就可能基本上把污水直接排到河里， 就像那些在很多发展中国家的城市里 正在发生的情景一样。
