People around the world produce an estimated 6.4 trillion litres of urine every year. BRL, a collaboration between the University of Bristol and the University of the West of England, want to make the most of this abundant resource. At the core of urine-tricity are microbial fuel cells (MFCs), which contain live microbes. When urine flows through an MFC the microbes consume it as part of their normal metabolic process. This, in turn, frees electrons. Electrodes within the cell gather these electrons and when they are connected to an external circuit a current is generated.

It is early days, but the work—which is being supported by a number of organisations, including the Gates Foundation—shows that urine could have the potential to make a significant contribution to renewable energy. It might also provide a commercial incentive to build more toilets—over 2.5 billion people around the world have no access to proper sanitation.

There’s money in them thar ‘nals.

The ‘P-Tree’ from Dutch design studio Aandeboom – recently ‘beta tested’ at the 2011 Roskilde Festival in Denmark.

But not at Oxegen. Obviously.

The P-TREE is a temporary tree-friendly urinal that can be fixed on every tree using straps and lashings. The P-tree gives a feeling of freedom during peeing. It is the same as peeing into the wild. The hoses from the urinal can be combined and connected on a waste pipe with container. The P-tree is very accessible for festivals, public gardens, events, etc. P-tree and Lashings are available in different RAL-colors.
