Composting Toilet Type for South Central Mexico?

Hey, Svante... did I ever answer you?
Let me know if Claire comes back. There's four dance classes a week up here, can't believe it.
I, obviously, am dancing my ass off and then collapsing in the hammock.
I have no ready made design for you.
The chambers should be BIG (about 4 times as big as for a dry toilet) and the vent should be BIG (25-30 cm diameter)...the floor needs to have a drain for the piss to leach out...that's
all now....

Hope all is well,

Hallo Mr. ART. The mighty VIKING is back, toasted at the ocean and ready to do some shitwork.

Giovanni seems to have come up with the same solution. A BATCH TOILET.

Now to the nitty gritty.
DO you have an actual detailed plan that could serve us, so that we can go ahead and build?
Otherwise are you dancing your ass off by African drums or just hanging out in the hammock.

Here Clair has left us all alone and the nice chicks have all left.
However Gwyn will be doing some circular, so we don't turn all fat and old.

My love to the sweet family.
Love to hear from you. Saludos to all Californians we know.
Svante. Subelefante.
