Getting Fresh Water From The Ocean - My Idea


scan06disk

if we run out of lakes etc we can get water from the ocean!"

Well well well nice to see someone thinking about our most important resource ! as for the Future when water is really gone what are we gonna do? forget oceans as the earthmoves closer to the sun and all sorts of changes occur, the only thing left to do is to join the 2 molecules H + O2 is some kind of ration that they form wate and thats the only was for mankind to survive. as for us we wont even be Alive then, hope so Think about it people ! the fastest and neares we can travel to safety is mars which in after a few years would also plunge into the sun thenwhat remains Nothing but Years of travel and finally the LOSS of mankind !



hehehe spooked you all eh hahahahahah
but still think about it !
Enjoy,

well then Iraq would want some other reason to charge us money neways
i do not think that we will ever run out of fresh water because of the water cycle.... which is the movement and transition of water through things like condensation, precipitation, transpiration, and evaporation.

basicly; Water evaporates from the earth goes in air up to clouds rains (or snows) back down to earth into lakes etc.......

so i dont think that we will ever run out of water...


You can't say that we won't ever run out of water perhaps not in america but I'm from Australia and I live in a city called Brisbane and my local damn is like at 20% capacity see through the stereotypes no I don't live in the country I live in a heavily populated city in Australia and i don't live on a farm.

We've been having a nation wide drought for a while now and you say that the cycle continues. our drought is caused by the Il Nino effect they think but it's coming to an end apparently. Look up more on the subject if you are interested because I'm afraid you've got it all wrong.

First of all, we aren't running out of water. We are running out of drinkable water. Second of all,

our population is increasing at a rate too fast to give them water or a bunch of other natural resources.

Third of all, global warming floods some areas and dries our some areas. It relocates the rain.

 

______

Here's how to solve the problem:

 

## Conserve water ( duh )

 

## Recycle water ( mentioned before )

 

## Import water

 

## Recycle pee ( it's gross, but they recycle the pee on the International Space Station,

and it's some of the cleanest water on Earth [ well technically not on Earth ] )

 

## Try to lower the rate our population is growing at so we won't have as many people

consuming natural resources, including water.

 

## Educate people about water

 

## Take water from the ocean and remove the salt. It has a lot of disadvantages like price and

everything, but it's a good natural resource.

 

______

 

I don't believe that humans have the capability to cause a significant drop in salt water.

Even though we can ravage the environment six ways from Sunday, the vast expanse of salt

water is simply too much for us to significantly lower.

 

I doubt that humans can survive long enough to significantly lower it anyway. If so much water

is needed, then how much of other natural resources are being used? Those other natural

resources like electricity, metals, land, etc. would have a tremendously negative impact on

civilization and may cause it's end even before we get to the point where we can literally

suck our planet dry.

well, that means we would have to get rid of at least 1/2 of the worlds population, to last till the earth is engulfed by the SUN !
it might be funny now but during those days u will be .........well yea think abt tht. hehe for now chill but then !

I didn't mean it like that. I meant that we should lower the rate that babies are produced so taking salt water and filtering it which has a high per-person cost, would have a slightly lower total cost.

I should probably add to my list to reduce pollution, even though a bunch of people already mentioned that.

Well it is easy to get water from the ocean it is in fact clean safe and not hazardus project in the beginning and if and when we come in contact with such problem as scarce water in the developed world we will start using it from the oceanes however there is another big problem which will happen oceans will become more and more salted and by that ocean currents will change affecting the climate of the world in many different ways this might be real problem because europe might end up like cold land and even further tornadeos and so on.So extensive use of such water is really dangerous for the hall life or for the mosr of it in the world.

Well if anyone can hook me up with someway to learn the process of changing salty water to fresh. Thanks.

More than twenty years ago, humans also thought, "The ozone layer is vast; we can't possibly cause any significant damage by using CFC's." Now, we have a gaping hole the size of Australia. See, it is this kind of aloof apathy that causes damage to the environment. "I didn't think it was going to be that big," or, "X Corporation had no idea it was introducing that much lead into the environment." How many times must we hear of these excuses long after the deed has been done and the damage, rendered irreparable?

 

Might I suggest that you also watch the movie The Day After Tomorrow. And, just in case that will be taking too much time and effort, I'll just explain a situation that, though presented in a movie, is quite real.

 

Ever since global warming began, chunks of polar ice caps have begun drifting out into the open sea. These fragments, known to us as icebergs, are made of pure water, not salt water. If this continues, we could reach a critical desalinization level that could radically alter the flow of ocean currents (This is true, not fiction. Apparently, the movie writers did some research after all)

 

Okay, so maybe I might concede that maybe we cannot greatly lower the salt content of the oceans by obtaining fresh water from it. However, in the current condition of our world, it might take, what, a few years or decades before we see what happens and could do no more than gasp, "Oh, $#!+"

I fully understand your point, but we seriously have a lot of ocean water. 70% of Earth's surface is covered with water.

Most of that is ocean water. Ocean water is also pretty deep too.

 

I also understand that we could suck the oceans of the world dry. But what would happen to our other resources?

If we take care of our other resources, we should not get the demand of ocean water that will make a dent in it.

Imagine what would happen to metal mining. The metal mining industry is one of the most hazardous to the environment.

If there is such a massive demand of water, and people are conserving it because cleaning ocean water is expensive,

then the industry would wreak massive havoc on the world compared to what's happening now.

 

Because people are trying to protect our other resources, if we can keep our more delicate resources safe, we can

keep ocean water safe.

 

PS: I've seen The Day After Tomorrow. I have it on DVD here.

Okay, okay. I could be wrong, yeah, but just in case I'm right, don't say I didn't warn you.
I'll probably grow into an old hermit, if only to nag, "I told you so"

To desalinize salt water, you'll need a heat source which should come as a boiler, you'll need vast amounts of energy to power that gigantic boiler. i.e. a mini-nuclear power plant. You pour salt water into the boiler, then turn up the heat. The steam should be collected and condensed to create pure water and the leftover 'brine' could be sold.Has anyone thought the idea of using raw 'materials' to create water? like combining hydrogen with oxygen atoms. That test facility in NASA actually creates rain because of the mixing of H and O


NNH1254

I think I misunderstood you, but if we just left a barrel out in Iraq we'd have a barrel of salt. You'd need something on top of it for the water, and it'd all need to be set up for every barrel, and you'd need to get the water from the ocean, and then all around the water-barrel-plant, and then back out wherever, and it'd all take up a lot of space. Solar panels would take up a lot of space too, but when we run out of oil we'd have a lot of space in Middle Eastern deserts with roads connecting them all because of where the oilfields used to be.

Well I'm sure you've all heard and said "if we run out of lakes etc we can get water from the ocean!" the problems is of course money because it costs a lot to heat the water and get the salt removed. Well I say either a)Leave a barrel of water of water out in the desert or iraq or some other really hot place. Or b)Use a ton of solar panels. This is still just a very small/insignificent/almost pointless idea because it would still cost a lot of money and take a lot of time. Well if you got any efficient ways of desillination and destilling water that may or may not be "better" than mine tell me! (to me the desert water-heating idea seems like it would cost less)

You have very interesting ideas, but the fact is that it doesn't just need to be heated to get rid of the salt. What heating does is separates the salt and the water, because the water starts to turn into a gas. The temperature needs to be above boiling. And then you need a tube coming out of the container of saltwater, going up, into another container which is cooled for the water vapors to turn back into water. Even if this was possible to be done in Iraq or some other hot place, you would get hardly any water out of it. Think about it... One barrel of water compared to trillions of people in the world.

As for the solar panels, solar panels are cheep, but it wouldn't help really. Solar panels output electricity, and you would need allot of electricity to heat enough water to suffice just one city, yet alone a state, or a country.

I liked reading your ideas, but I don't think they would work. Keep up the ideas though.

amit nigam

hi friends,sorry dazappa... i would beg to differ with you on both fronts....first of all that heating in deserts issue...there are many problems in it....first of all as posted in last post the amount of water needed is too much for total population that this thing is not practical...secondly if we think for once that its possible then what about cooling it down back to water as pointed in last post...third one is the political issue... as we see there are so many wars been fought over petrol then can you imagine what would happen if a bunch of countries hold the key to lives of the people of whole world....you see you can live without petrol...though you will face too many problems but still somehow you can manage....but what without water.... so if the water resource will be in the hand of just a few countries then i think it will be a very precarious situation....also if after all that we assume that ok water is being treated in deserts then can you imagine the cost of transportation....it would make it non feasible at the outset...as far as your solar cell thing is concerned i feel that that is also not possible, atleast in the near future...because of such low efficiency of solar panels they are not even able to provide the target set for them of electricity output of the world even today...so i don't feel that it will be possible to have such solar cells which can generate electricity to provide water for the world...i am placing my bet on nuclear fusion....i feel that within the next 20 years generating electricity through fusion will become feasible and profitable and then we will have almost unlimited source of energy....then we can easily use that electricity for desalineation.....that is what i feel.....if anyone disagrees with me then please do write...i prefer critics more than followers...since critics make you learn a lot...ok bye friends...keep writing...

Ishbir

Yeah, Desert heating would cost less but who would take so much of water to the deserts? I wonder God takes it but will he? I recently heard about Solar Guyser which uses Sun Power to heat water. There is a lot of direct sunlight in Sahara. Why dosen't the Arabic government put some of them there and all the electricity made from them used to heat a tonne or more water on a large scale. Just a thought. The government of my country is pretty useless, does nothing except eating and farting!


master_bacarra

one way of getting fresh water from the ocean is by freezing it. i think someone mentioned that you could get it from the polar caps. yes indeed. the water that you get from the ice on the polar regions are pure. once the water comes to the polar caps and freezes, any impurities are taken away from the water. i believe my marine science prof told us that this is one of the techniques used to make juice concentrates.so there you go. well whichever process takes faster will be most beneficial to humans.


Tetraca

There are salt water refinement facilities out there. The cost of maintaining them is usually what makes them unattractive, IIRC.


nol

You could say a lot of things like this..You could say why not take out all the gold while your at it? But there will always be the same ammount of water that was here 10 trillion+ years ago. Its called the water cycle, it will never leave our earth, it can't.


srujanlive

Well did you consider thae costs of actualy getting water till there...
