Though we have plenty of water around us, sometimes we have to face problems while using fresh water. This happen because of there is not enough supply of water against the endless demands of increasing population. So, the world leaders and planners are thinking about the reuse of water more efficiently or trying to sourcing new way of getting water.

So, you want to talk about reuse of water in regards to cinema operations? Or in case of water cooling inside a film projector?

Getting new water will be quite a trick. We don't even know where the water we have came from.
Maybe we should look into asteroid mining?
Still, this really seems outside the job scope of film handlers.

It's perfectly relevant. If you don't ingest water, you will die and therefore not be able to be a film handler! [beer]

This fellow's confusion seems to be about two things: one, "endless demands of increasing population" doesn't cause a reduction in the amount of water on our planet... the water is not always where the people are though and local supply shortages are unavoidable if people choose to live in arid areas. I suppose one can imagine enough people that all the world's water would be temporarily trapped in their bodies but it's not going to happen. And two, there is no practical way to make more water. What the planet has is all there is - or will be in a practical timeframe. Occasional ice meteors may hit us but that is not going to help. A massive ice asteroid arriving might increase water supply considerably but the impact effects would likely end Human (if not all) life here. When the Sun goes red giant the water will all be blown/boiled off... but that will not be a factor in our demise.

Tank Girl

One of my favourite silly movies. The bad guys have a hand-held gadget that they shove into people's backs to dessicate them and the water gets recovered into a jug that's part of the device.

And you'll note that I've successfully moved this thread to a movie, even....

It's not that the planet has too little water....it's that it has way too much effin salt. And if you think you don't know where the water came from, try to explain where all the salt came from. There are no big salt asteroids floating around our galaxy.

According to what they told me, the salt actually primarily came (and is still coming) from rainwater finding its way back into the ocean via small streams and ultimately rivers. During this journey, the water picks up and dissolves minerals.

Many of the minerals in the seawater are being used by the organisms that live in it, they just don't seem to have a particular liking to sodium and chlorine. (Corals for example, are almost entirely made up out of calcium and an important mineral for almost all living organisms.) Sodium and chlorine also tend to dissolve pretty well in water. That's why the primary ions in sea water today are sodium and chlorine. (Somewhere around 3% of the mass of water is salt if I remember correctly.)

Although the main ingredient of any sea salt is still Sodium Chlorine (a.k.a. ordinary table salt), most sea salts contain a lot of other ingredients, especially minerals which were obviously part of the sea water composition.

Posted by Dave Macaulay (Member # 813) on 11-07-2017, 07:06 AM:

All salt is sea salt. Salt mines bring up the remains of ancient dried up seas. I would rather have that prehistoric sea salt than dried out mediterranian seawater with everything humanity has been dumping in the sea for thousands of years.
OK, it can be made by combining sodium and chlorine but the industrial source for those is dissociated salt... so back to the sea.
"Sea Salt" is just a way to make suckers pay a lot more for salt.

Las Vegas has used recirculated water in all of the fountains, lakes and indoor decorative pools for probably going on ten years now....

So you're saying that the marketing should be taken with a grain of salt? [Big Grin]

Didn't Reza say elsewhere that his favorite movie is Waterworld? [Wink]

Posted by Dave Macaulay (Member # 813) on 11-08-2017, 04:05 PM:

Other than old world town fountains, originally intended as a fresh water source before indoor plumbing... most every fountain uses recycled water with fresh water makeup for evaporation and spillage. That helps make adding a jug of bubble bath so entertaining.
Or do you mean Vegas uses processed wastewater (sewage) in fountains?
