Since there have been so many complicated inventions these days, do you think that it is too...
complicated to produce a filter for a machine to take salt out of ocean - and other salty - water? After all, there is so much water on the earth which we cannot drink because it is too salty, why has nobody done anything?
probably stop buying salt ex n add salt water for cooking purpose!
Desalination plants already exist all over the world to remove salt from ocean water and make it drinkable. There are several plants in the middle east and California even has plans for a few. The filtration system is complex and is very expensive to build and maintain. For now, other technology's tend to be cheaper which is the main reason desalination isn't the norm. Scientists and engineers are continually working to improve the technology to make it more efficient and cheaper to operate.
Let's not forget that there is plenty of water in our air as well. We can build machines, called Atmospheric Water Generators, to extract water from the air. This technology is also relatively expensive, but it does work. The US military used these water generators in the Iraq war. I wrote a hub about this technology if you are interested.
You bring up a good question and it does seem easy enough. If we can filter human waste from our water...why not salt. (Wish I was a scientist) As for why no one is doing anything, it has to be money right? That's what drives progress nowadays. Would it drive down the cost of our water bill today thus hurting the industry? If it's overly available, you can't sell it for as much...
Call me a conspiracy theorist but I strongly believe inventions or ideas like this get shot down all the time because it's "not good for business". How long and how much did auto manufacturer's get paid to keep low fuel consumption motors out of cars by oil companies???
At the beginning it always expensive but they find ways to improve inventions and save money. Are they saving it for when we run out of drinkable water?
Sure. Didn't they save those fuel efficient cars for when we were "running out of oil"? Besides, we can't dip into funding for researching cow farts 2 address something as useless as water. Best time to release products r when desperately needed.
It has been done and is called desalinization and is very expensive.
