西内SINE

在我们认识以后，我对这个问题进行了研究，发现洛杉矶自来水公司打算在胡佛水坝下游20英里处安装一个水泵，在电力需求低的时候把水调回去。我不知道他们为什么想用风能和太阳能来驱动水泵。总之，最让我惊讶的是意大利和瑞士已经这么做了很长时间了，但是没有用风能和太阳能来驱动水泵。但是他们日夜都有充足的水。太阳能，甚至是大型公用事业公司的太阳能，都使用电池，而这些电池所提供的电力并没有大坝所发的电那么多。这个想法好吗？
I looked into this sometime after we met and found the Los Angeles water utility thinks to install a pump 20 miles downstream from Hoover dam and move water back up when power demand low. I do not know why they think to use wind and solar to run the pump. Anyway, most surprising for me is Italy and Switzerland have been doing this for a long time already, but not wind and solar for the pump. But they have almost all the water they need ready all day and night. Solar, even big utilities solar, use batteries, and these do not provide as much power as a dam releases for as long as sometimes is necessary. Is a good idea, huh?

也许他们可以把它抽回到浴缸里？
Maybe they could get it back up to the bathtub rings?
