Is there a public design of an incineration toilet?

I cannot find one online, so I devised one.
Will it work?
How is its efficiency?
Is it better to point the propane flame to the waste at bottom of waste bowl?

Hi Douglas;
Yes indeed there are incinerating toilets.  
Here is just one     https://incinolet.com/
I think you are hoping to find free plans to build your own?
I doubt they would tell you on purpose exactly how to build your own.
But by reading all the different manufacturers descriptions you should be able to figure it out.

I did a look around out of interest.
It seems the energy usage of these systems is high and that may be an issue for you.
Also, the design to be efficient means DIY may not be practical, because I also could not find anything about building one.
