There is no such thing as a Stupid Question!
Don't be embarrassed of your curiosity; everyone has questions that they may feel uncomfortable asking certain people, so this place gives you a nice area not to be judged about asking it. Everyone here is willing to help.
- ex. How do I change oil
- ex. How to tie shoes
- ex. Can you cry underwater?

Thanks for reading all of this, even if you didn't read all of this, and your eye started somewhere else, have a watermelon slice ๐.

It's harder to freeze salt water then fresh water, do it's not economical.
The most energy efficient method of desalination i believe uses a membrane and pressure to get the fresh water to one side.
But these aren't even the biggest issue. The real question is what do you do with the left over brine? Desalination is not 100% perfect. You're left with fresh water and a salty sludge called brine. It's extremely difficult to dispose of without causing environmental impact
That is a really good point! I wonder if this means the polar ice caps have saltier oceans... but I'm guessing the brine is denser so it stays on the bottom.
