This Idea Wasn't All Wet: The Sensing Water-Saving Shower Head Debuts

Cars That Think

In 2012, with California in the midst of a severe drought, Schneider, then a mechanical engineering graduate student at Stanford University , once again tossed out a “cool idea.” He imagined a shower head that would sense when the person showering moved out from under the stream of water. You’d waste more water than you saved.

Vitruivan crowd-sourcing funding for novel biofuel from sewage treatment bio-solids

Green Car Congress

EEB is produced from organic waste, including (and initially) sewage treatment bio-solids—the leftover, dirt-like organic material that remains after a community’s wastewater is treated. Vitruvian Energy is trying to crowd-fund its novel biofuel EEB (ethyl 3-ethoxybutyrate). Vitruvian has modeled production costs at $2.58-3.73

Although most national parks ban commercial foraging, about three-fourths allow people to explore and collect their favorite crops for personal use. Individual parks set limits each year, some like Death Valley in California and Nevada restrict the collection of foods like nuts and berries to a quart a day, and only for personal consumption.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

Wei Gao/Caltech California Institute of Technology’s Wei Gao developed a self-powering “electronic skin.” Personalized health care could revolutionize traditional medical practice,” Gao says. Using built-in fuel cells, the device absorbed the lactate in the sweat and combined it with atmospheric oxygen to generate water and pyruvate.

Greenius Will Meet With Al Gore To Talk Climate Reality

Creative Greenius

We may well be as doomed as doomed can be already – as I frequently tell my friends that we are, and the “ Hell and High Water ” may already have arrived earlier then even Joe Romm’s dire predictions, but I’m not quite ready to cash in my chips and give up the ghost.

Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities. Diane Pataki, University of California, Irvine.
