When you use the Bee-vi toilets, you will receive the Feces Standard Money (fSM). The powdered feces are used to produce various energies such as methane and biodiesel and the remained sludge is used as fertilizer.
Feces, like gold, is limited and precious; nobody can make more than a certain limit, and it can be converted to energy. fSM can automatically become ‘basic income,’ as long as we put feces into the reactors on a daily basis instead of continuing to flush the toilet.
The concept of fSM was introduced on Edge https://www.edge.org/response-detail/26660
