Drinking water from the Sea is possible?
Drinking water from the Sea is possible only when an affordable way could be found to squeeze the salt out of seawater which is a costly endeavour, mainly because it craves energy. More than 11,000 desalination plants, cleaning billions of liters of water a day, are located throughout the world, primarily in the Persian Gulf,. Most of these Gulf based plants use an older technology called multistage flash distillation, which basically boils the water. The process is extremely energy-intensive, which brings a problem for just about every country except those in the oil-rich Gulf countries. This method, too, is not that much bearable and cost-effective. According to an estimate about $ 2000 for a cell that produces 3,785 liters of desalinized water per day is quite expensive. Besides, more environmentally dangerous issue is where to put all that extracted salt?
Search for a viable and cost-effective technology is the thirst. Development strategists are way of investing in such expensive technologies in the hope that they eventually will become cost-effective. Some of the more utilitarian water technology research is being done on creating systems that are simple and the cheapest. A researcher, Widever spent his time in his Munich lab monitoring a model sewage system that automatically recycles household water multiple times. It means whatever amount of water is used returns to the same houses after it is cleaned. Rice producing countries including India, no crop requires more water than rice. One kilogram of this staple requires 1,500 liters of water. World Water Development Report of the United Nation says that the water often drawn from rivers, becomes saltly because of high evaporation rates, which then salinises surrounding bodies of water. Now, it is possible to ask people to give up rice. This could be one way to reduce the world’s water crisis, but half the world’s population consumes it.
