While noting costs are falling, and generally positive about the technology for affluent areas in proximity to oceans, a 2004 study argued, "Desalinated water may be a solution for some water-stress regions, but not for places that are poor, deep in the interior of a continent, or at high elevation. Unfortunately, that includes some of the places with biggest water problems.", and, "Indeed, one needs to lift the water by 2,000 metres (6,600 ft), or transport it over more than 1,600 kilometres (990 mi) to get transport costs equal to the desalination costs. Thus, it may be more economical to transport fresh water from somewhere else than to desalinate it. In places far from the sea, like New Delhi, or in high places, like Mexico City, high transport costs would add to the high desalination costs. Desalinated water is also expensive in places that are both somewhat far from the sea and somewhat high, such as Riyadh and Harare. In many places, the dominant cost is desalination, not transport; the process would therefore be relatively less expensive in places like Beijing, Bangkok, Zaragoza, Phoenix, and, of course, coastal cities like Tripoli."[25] After being desalinated at Jubail, Saudi Arabia, water is pumped 200 miles (320 km) inland through a pipeline to the capital city of Riyadh.[26] For coastal cities, desalination is increasingly viewed as an untapped and unlimited water source.

Uhm...
You have no idea about the amounts of Wather humans actually "use" do you?
Imagine the amounts of "Sand", "Plastic Bottles" and "other Stuff" you would need to just "clean" the amount of wather an average 1st World citizen needs per day... And then you still don't have the wather at the place you need it.

My trolling detector is bad, i can't tell if VelJa is serious or not.

Why did there is so much water problem in the world, why don't take water of the ocean and filter it to make it drinkable ?
Dont tell me that its impossible omg costs huge amounts of energy, and a decent bit technology which is not that available in most regions that have severe water shortages. what ? WHAT ? taking the salt off the water need HUGE amounts of enrgy and technology ? ahahahaha i used to do it when i was 10 y/0 with plastic bottle sand and some other shit in classroom ^^ Don't tell me you can't adapt the -easy- process .
I am pretty sure you didn't.
As others have mentioned, desalinating water is a very energy-intensive process. One can use solar power to do this directly, but you still need a gigantic and very expensive facility to do so.
Another big problem with water is that usually the problems are local, and it is hard to transport large amounts of water over large distances.

Come on don't bitch with me guyz
I can understand that the process becomes hardcore for massive production but ..
I'm 10000% sure this is viable but the only one reason no one is making this is that it don't bring us $$$$$$$$$$
Like the water-engine for cars if you prefer

There are actually not that many places with true water shortage these days. It's fortunately one of the areas we have made huge progress since the 90s: http://www.unicef.org/media/media_61922.html
However, the remaining places are usually not right by the ocean (sub saharan africa primarily) so in addition to the huge amount of energy for desalination you will need transport across politically unstable regions. Which is pretty much the number one reason why those places are still fucked up.
In other places, the problem isn't really (desalinated) water, but clean water. There is plenty of water, but in many places it's contaminated with disease and/or waste.
And yes, energy is a major factor. Countries with cheap energy and ocean access are in fact desalinating sea water on large scales:

Uh, if you have a way to do it cheap and you do it for California, you'd get very rich very quickly. Capitalist imperatives still work.

French spoiler
+ Show Spoiler +Non, c'est pas possible. Le processus est beaucoup trop lent, notamment parce que le problème d'eau provient en grande partie de l'agriculture. On ne peut tout simplement pas désaliniser assez d'eau pour combler leur demande. Ils en consomment énormément. L'utilisation de l'évaporation ne marche tout simplement pas pour de grandes quantités, à moins de vouloir couvrir la planète entière.
Et encore...
It is not possible. The process is way too slow, namely because the water shortage issue largely comes from agriculture rather than from personal use. We simply can't desalinate enough water for agriculture, they just use too much. And the using evaporation to desalinate water just doesn't work for large quantities, unless we want to cover the entire planet with such devices... and even then.

Too much French

you should have announced that with "pardon my french, but..."
but since he now referenced the water-engine for cars it is pretty well established he is trolling.

Yeah, at this point i think VelJa is just trolling.
"Water Engine for cars". I am now going to google this just to have a good laugh.

There are many people who believe that the h2o engines aren't being invested in because of the oil lobbies and whatnot. There's a part of truth to it - there's too much money to be made with the alternative, so companies are not yet investing massively in R&D for new sources of energy. He's perhaps a bit overzealous about his beliefs though. But I don't think he's trolling, just wrong 
That said I've been wrong before. I don't know why people would troll on TL though, TL doesn't like that.

there is a great documentary about the suppression of those ideas: http://en.wikipedia.org/wiki/Chain_Reaction_(film)

fuck yeah guy i was just having fun on this topic.
I really enjoy the part where i was claiming doing this in school with sand and plastic bottle ahahah. So gud. Simberto my man he knows it
The Water-Engine was may be too much, i will be more aware next troll :D
nvm, thanks all for serious answer. TL is awesome ^^

I dunno. Germany has a nice democracy. I really admire it. Oh wait, what's this? That's a "Made in USA" sticker!

Is this capture and redirect asteroids thing from NASA as stupid as it sounds?

Seems like they could use a refresher course.
