Like many other Pacific island countries, Nauru depends on desalinated water for its inhabitants' consumption despite being surrounded by the blue sea. Xinhua's Gao Yang takes you to a desalination plant in the country to see how it converts seawater into freshwater for residents in Nauru. Pro...
和第二段"At night,people pour sea water into the ponds.The next day,the hot sun shines through the covers.The sunlight runs the water into steam(蒸汽).It goes up from the ponds.On the inside of each cover,the little drops of steam run together to make big drops.People then collect ...
One good way to get water is cutting through a frozen lake or river surface. Warning: Beware of bad water Never drink from water that has dead animals or animal remains in it. The water probably has lots of minerals in it and has become toxic. You have the same problem with seawater—...
(2), vacuum pumps(3,4), flat evaporation plate(5) having high frame on both sides for preventing a water leakage; an inflow tube(6) connected to the vacuum evaporation tube(1), outflow tubes(7,8), a connector(9) for flowing steam from the vacuum evaporation tube(1) to the cooling...
If a drought is present, pumping water out of a permanent stream to our ponds or tanks can make a huge difference. Seawater desalination is expensive with current methods like reversal osmosis. However, using solar distillation could be practical if you have enough space. E-Course: DIY Off-Gr...
How much seawater has been sprayed into the Fukushima Daiichi nuclear reactors to keep them cool More (31) than the number of tons of water is the amount of sea salt that was (32) in the reactors: ninety-nine thousand pounds (33) in reactors NO. 2 and 3, and fifty seven thousand in...

They pushed up (5) through the water. Land from the bottom of the sea became mountaintops. Seashells and fish bones were pushed up,(6) too. They (7) were far away from seawater. They were left high and dry. The seashells and fish bones were covered with soft mud and sand. The mud...
According to Sirkar, his system is extremely efficient -- it can produce 80 liters (21 gallons) of drinking water per 100 liters (26 gallons) of seawater, about twice what existing desalination technology can produce. One potential downside of DCMD is that it requires a steady, inexpensive...
Studying the microscopic phytoplankton in the water helps monitor the effects of global warming. Samples are packed up and sent off to be analysed by researchers who can't get here themselves. 研究水中微小的浮游植物可帮助监测全球变暖的影响。样本会被装好并寄给无法亲自到场的研究人员进行分析。
