Related: About this forumHuman urine bricks invented by South African students
Human urine has been used to create environmentally friendly bricks by university students in South Africa.
They combined urine with sand and bacteria in a process that allows the bricks to solidify at room temperature.
...
Regular bricks need to be baked in high-temperature kilns that produce large amounts of carbon dioxide.
...
The bacteria produces an enzyme that breaks down urea in the urine, forming calcium carbonate, which then binds the sand into rock hard, grey bricks.

If they really are usable as bricks (ie standing up to (possibly slightly acid) rain, frost in most climates, etc.) then that might be good. They are in a sense a by-product - 1 brick comes with 1kg of fertiliser.

people to pee. Can you imagine getting paid to sit around all day drink water and pee. Well maybe not sit as you will need to push that water down as soon as possible. Hmm, I do not know about this. Could you say things like urine my house?

Man sits in the bushes along the road with stacked cases of beer and drinking them at a furious pace. Questioned by a passerby as to what he's doing tells him "I'm working!" "Really" says the walker "What kind of job is that?" "I'm in brick manufacturing" "And they pay you to do that?" "Of course" he replies..."How much do they pay you?" "I don't know, I've always passed by payday!"...
