Since early childhood, you've always been encouraged, maybe even forced, to drink water. Its healthy, pure, and most importantly its one of our basic needs for survival. While two-thirds of the human body is composed of water already, drinking potable water is essential in the process of respiration and energy. Water covers about 70 percent of the earths total surface. So in short, those "greens shades of crayon" of the colored globe are dominated by the blue Crayola crayon.
So why is that 100 percent of the worlds population are not adequately hydrated by the earths purest substance? While water takes up 70 percent of the earth, only 3 percent of that is drinkable - the rest is considered "undrinkable" because it is salt water. As a result, more than a billion people, more than one-seventh of the world, lack access to drinking water, as well as proper sanitation. Sadly, each year millions of people die due to lack of water and hydration, and waterborne diseases.
For decades the "we have to revise a plan to get drinking water into these countries" line has been overused, and no actions have been taken. Meanwhile, human beings are still suffering. So what can we do to reverse this crisis? We start by putting into effect the most logical plan. Since 97 percent of the earths water is of salt water, we have to eliminate the salt. We know that in order to precipitate salt, water must be brought to an extreme boil. Our scientist will do exactly that, just on a much greater scale. Underwater plates will be positioned at sections of the sea's bottom. as the heat intensifies, salt will began to precipitate, thus making more and more saltwater drinkable.
The idea of finding a way to purify salt water is one that would change the world. I would caution you to put it in the oceans just because it could dramatically cause chaos in the ocean's ecosystem if the salinity of water changes too much. I know for instance that if coral has even half a degree of change in temperature it can kill of the coral completely. Perhaps there is a way to make this into a portable unit that a person living by the ocean could grab a portion of water and then purify it from their own home.
ReplyDeleteI agree with the IST195GA, it is a great idea, kind of mad I didn't think of it, but I would put more thought in to what the TA said you would have to think of a way of implementing your idea without affect the wild life that inhabits the ocean because although we need pure water, they need salt water just as much. So think about somehow being able to move large amounts of salt water to and area in which it could then be purified
ReplyDeleteAs above, I think it's a great idea, but you have to worry about effecting the ecosystem. If this was on a large enough scale (which I am assuming it is, in order to provide a reasonable amount of water for consumption for a body of people) you not only have to worry about your local ecosystem, but possibly even the local weather. If the salt would precipitate as you wanted, how would you remove the precipitate? Or further purify the water in some way? Is there a special temperature you have in mind?
