Power/Performance Bits: Jan. 2


Hydrogen from seawater Engineers at Columbia University are developing an ocean-based photovoltaic-powered electrolysis device that can operate as a stand-alone floating platform to split water into hydrogen fuel and oxygen. State-of-the-art electrolyzers use expensive membranes to maintain separation of the H2 and O2 gases produced by water electrolysis. The new device relies instead on an... » read more

Power/Performance Bits: Nov. 14


Bacteria power wastewater cleanup Researchers at the King Abdullah University of Science and Technology (KAUST) are exploring ways to detoxify warm, salty industrial wastewater while simultaneously generating electricity. They are using bacteria with remarkable properties: the ability to transfer electrons outside their cells (exoelectrogenes) and the capacity to withstand extremes of temperat... » read more
