Power/Performance Bits: Nov. 21


Greener greenhouses Researchers at the University of California, Santa Cruz are testing greenhouses capable of generating some of their own energy, without hampering plant growth. Greenhouses use electricity to control temperature and power fans, lights, and other monitoring systems. Electricity-generating solar greenhouses utilize Wavelength-Selective Photovoltaic Systems (WSPVs), a novel ... » read more

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

Transient electronics Researchers at Vanderbilt University took a new approach to transient electronics, creating circuits that, rather than requiring active behavior to destruct, will dissolve if not kept above a certain temperature. Using silver nanowires embedded in a polymer that dissolves in water below 32 degrees Celsius – between body and room temperature – the team made a simple... » read more

Insect robots on the water Taking inspiration from water beetles and other swimming insects, academics at the Bristol Robotics Laboratory have developed the "Row-bot," a robot that thrives in dirty water. The Row-bot mimics the way that one aquatic insect, the water boatman, moves and the way that it feeds on rich organic matter in the dirty water it swims in. The Row-bot project aims to ... » read more
