EirGrid has published Tomorrow’s Energy Scenarios 2019, an analysis of Ireland’s electricity sector over the next 20 years. One of its key findings is that electricity demand will increase by a range of 28% to 55% by 2030 compared to 2018. Read more: https://t.co/egTFgKyPVFpic.twitter.com/VBkbJqUodY
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.
Melanie Hoff, a student at Brooklyn’s Pratt Institute, connected cables to a large sheet of wood and passed 15,000 volts through it, resulting in some rather unexpected fractal-esque patterns, like slow motion lightning.
We have no idea what this means but we’re pretty sure things will never be the same again.
