I am sorry you feel that way.
It was a serious question.
My main concerns are-
Salt in Water
I don't understand the chemistry of salt (I have no understanding or training in chemistry -but try). I can't understand why you can't just add some chemical to water and all the salt molecules just fall out. That's why I was fascinated by my pool chlorinator (new house; first pool-saltwater).
How come this technology is not used to make drinkable chlorinated drinking water?
The growing lack of drinking and irrigation water is I feel the major problem facing mankind today.
My local Council, as of today, looks like banning all use of hoses- allowing buckets and watering cans only. We are in the middle of the worst drought ever. Day after day of sunny wide-blue skys is great but it has not rained here for at least 6 weeks and those clear blue skys are becoming sinister.
I have been mucking about with designs for a low tech. inexpensive solar still. Something easily used and transported and inexpensive to make to produce large and small amounts of drinkable water. I have some design ideas but need to make some proto-types to test.
Saliantion of Soil
This is a major problem in my country.
An area the size of the State of Victoria will soon be useless because of salt rising to the surface of the soil. The soil just turns white, everthing dies.
This is the result of land clearing and the huge underground aquifers under a good part of the country.
As the trees go, the underground water rises and the farmland is ruined.
Recovering the land is impossible.
This is a major tragedy.
I believe the problem is not unique to Australia
Why can't the salt be neutralised by some chemical?
I have read a number of books called "salt" most give historical rambles.
I have exhausted my local library.
I have done some web research on Salt -see above post- but am still puzzled.
I offered the topic because I thought, although a simple thing, salt rules our lives in a number of ways. I feel it is an important an issue as Global Warming or Dimming.
I thought I might provoke some interesting conversation on desalination and on the
environmental and
medical aspects of salt.
I guess I should have posted on those forums as the
chemistry forum seems to think such a lowly topic is beneath them?!
