Tha Gates throne solves for different problems.... prioritizes water shortage/recycle and scalability.It could be far more extreme. This "solution" is an example of what happens when more dollars than [good] sense are applied to the problem.
RV and boat use prioritize simplicity... scale of use is smaller and recycling non-potable water is pretty much a non issue.
I like the clean design of the OGO. I'd like the internal solids bucket better without the through-hole in the base. Seems like a magnetic stir-bar would solve for everything but easy cleanup.
