I'm Rodrigo and I'm writing from Madeira island, Portugal. I've been in the composting toilet business and research of my own for 4 years. I'm willing to find in this forum a solution for a challenge that I have in hands.
It goes like this: since a composting toilet doesn't use water to flush human waste, there is a need for a vertical fall of the waste into a tank. With this the user when in need to use a composting toilet, will have a visual contact with others people waste inside the tank. From my questions to the users this is the most unpleasant side of using a composting toilet.
So my idea is to create a visible flat laser beam just right bellow the toilet lid, so the users cannot see inside the tank and the waste will still have a free vertical fall. Do you think that this is possible to make? I was thinking of using a laser pointer, pointed at some kind of amplifying glass that would transform a visible laser beam into a visible flat wide beam. The color of the beam isn't important for me. The goal is to "hide" the waste inside the tank for a human eye.
Tell me if you guys need more information or drawing about this idea. Thank you!
