Water H2O

WATER

I have been doing a little research on water,( now that we have solved the Global Warming problem) and have been surprised about how little we know about this ubiquitous and essential "thing".

I have been looking especially at the physics and chemistry of it. Most people say it is very odd 'stuff' and shouldn't be able to do a lot of the things it patently does do.

Someone told me, here, how water adsorbs heat (from sun) which was a revelation to me. A revelation my old brain has already forgotten :confused:

How come it wants to soak up all our Co2 emissions? (or try to)

How come only 1% is fresh

and

How come water isn't drop-dead-easy to desalinate?

There are many odd beliefs about water-social and scientific and fairy stories- some even with some science behind them like magnetism and water-- where argument flares.

In folklore, magic and religion water and especially springs are sacred

Look at the R. Catholic "Holy water". people are immersed or washed in water to wipe away original sin, to be re-born in Christ.

Water is pretty too. We are always taking photos of it. It can be all colours not just the blue commonly associated with it.

In Australia most of us live near it (the sea) yet depend on what falls from the sky thousands of miles away

Water brings and is essential to life but also seems able-in storms- to bring death and destruction.

We like to visit it, sit in it, swim in/under it, ride it, float in it, skim over the top of it, frolic in it.

Some recommend a daily drink of it.

Some won't drink recycled water but are happy to drink water collected in a dirt dam.

There are many famous quotes about water.

W.C. Field's is a favourite "I never drink water. Have you seen what fish do in it!?"

Apparently, many of our common medical ills come because we/humans stopped living in water--some aeons ago (hernias for example).

The developing foetus at one point even looks like a fish. Often children are born with webbed fingers or toes.

You can make the closest thing I've seen to a continuous -motion-machine from it:-

Hydraulic ram pumps - Technical Information Online - Practical Answers

.Yet we spend $billions pumping and piping it about the planet.

Without water we could not make much electricity or have even started The Industrial Revolution.

It has shaped and made us and our history.

Now, on a blue planet, we are said to be running out of it.?

How is this possible? ""Earth" is a bad name for our planet; it should be called "Water". From space, you can see, there is a lot more water than earth.

Many diseases are carried/transmitted in water Yet most are simple to eradicate. It is said, that the large population of China, is in part due to Tea drinking, which involves boiling water.

Where to start? :-(

now that we have solved the Global Warming problem

No, no I dont think we have. There are still tons of co2 being released into the atmosphere enlarging the hole in the ozone layer. Where did you come up with this idea? We will only solve the problem when we close the hole in the ozone and we harness our CO2 emissions.

It can be all colours not just the blue commonly associated with it.

Water reflects light and light can be tons of colors becuase of the spectrum.

Yet we spend $billions pumping and piping it about the planet.

you can thank gravity for that.

How come only 1% is fresh

Becuase most water is seawater. Im not sure if it is because there are natural salt deposits under the oceans but I do know that the only reason we have fresh water is because we have rain.

on seawater:

define: osmosis

define: diffusion

when ya think about it, this really explains seawater.

Solvents(of which water is one) like to move all the molecules suspended in their murk to have an even distribution. Might be time to pull out your high school chemistry books and take a look on solutions and the mixing of concentrations thereof ;)

Hi.

There is a drop dead simply way to desalinate sea water into fresh water. It's called distillation.

Make a still. Put in sea water. Heat to boiling. The condensate is pure water.

However, it is energy intensive, and if fossil fuels are used, the process adds to climate instability and global warming.

A 5 litter pressure cooker, a length of copper tubing from Home Depot, a couple of band clamps and a heat source and you've got a desalinator.

you can use the sun to distil water.
