The way to engineer a good heat transfer system has never been developed but could be.

True water is good, but has such a small window of temperatures in which it remains in liquid form.

Water is used wherever it can be, depending on the application, because the bottom line is always cost, and water is cheap and easy to use.
Look at all the evaporative coolers that cool our homes (in dry climates) and all the steam turbine condensers, and all the cooling towers. If you take the time you will find all kinds of applications for water being used as a heat transfer medium.

"The way to engineer a good heat transfer system has never been developed". LMAO !!!
Wrong!
And who said water isn't used as a heat transfer medium? What do you think is used in your car (hint: ethylene glycol + "a secret ingredient").

No. The thicker the fluid the longer it will remain heated.
Some types of oil or even sand would be better than water.

depends on the specific application

no it does not retain heat as long as other liquids like oils or thicker liquids

I believe molten sodium is more efficient. It really depends on your application.
