Answer 1

Cover a large satellite dish with tiny mirrors, like you were tiling a floor.  Play around with it until you can get it to focus somewhere that you can put the water.  It should boil in a few seconds.  MIT basically did this and was able to burn wood within a minute.

Answer 2

Black absorbs heat so surround or contain water in a black container that is in the sun.

I heat a pool by coiling black garden hose into a spiral and putting it in a frame that is covered with plexiglass. 100 feet of hose gives water about 100 degress f on a sunny day.

I used to just lay the hose flat on a blacktop pavement.

Try this but if if the water is just sitting still, be careful, it can burn you!

bye for now.

I would also suggest you reword your question with a little more detail about what you need it for and post in engineering, you might get some more interesting ideas there too.

Answer 3

put the water in a black plastic container
