I took a clean, plastic-Housing Garden Sprayer we had laying around and painted it flat black. When Boondocking, I put a piece of 'Reflectix' in back of it in a half circle up against a small pile of Rocks in a natural formation. This helped concentrate Solar energy to the back Sprayer side not in direct Sunlight. I used the original Sprayer Head. Yah, the mist coming out was kind of fine, but it got the job done, and saved Water. That fine mist cools as it comes out, so you have to let the Water heat up to a higher temp than what you think is comfortable. I suppose you could get a small Drill Bit and make a few holes slightly larger in the Garden Sprayer Head.
