This installment was inspired by the editorial illustrations of Rob Dobi (though this looks nothing like his), and the following paper from JACS, wherein the authors describe a cubane-based water oxidation catalyst. It is capable of oxygen evolution, a key component in artificial photosynthesis, which is a key component in playing nice with earth.
