A new washing machine design uses 90 percent less water and reduces utility bills by 30 percent by cleaning clothes with tiny plastic beads. The machine by UK company Xeros Ltd uses 3mm-long nylon beads that can get into all crevices and folds of clothing and absorb stains and dirt.  Stephen Burkinshaw, a polymer chemist at Leeds University, discovered that nylon beads at 100 percent humidity could attract stains away from clothing and into the center of the beads, preventing deposition back onto the clothes

Concentrated Solar Power Isn’t Just for Deserts, It Could be for Walls Too

Comments Off on Concentrated Solar Power Isn’t Just for Deserts, It Could be for Walls Too

Usually when you read about concentrated solar power, it’s referring to some large project destined for the Mojave Desert, but Syracuse’s Center of Excellence in Environmental and Energy Systems (SyracuseCoE) has set out to prove that this technology can be used in smaller, colder settings. SyracuseCoE in Syracuse, NY is itself a LEED-platinum-certified, 55,000 square-foot building that serves as a testing ground for renewable energy and efficiency technologies.  The south wall of the building is home to a concentrated solar facade that, at first glance, resembles the frosted cube walls found in doctors’ office waiting rooms. This 8-foot by 8-foot facade houses several clear pyramid lenses that track the sun and concentrate the rays onto high-efficiency PV cells.  Extra energy not converted to electricity is used for heating water and radiant heat in the building.  And because it’s made up of clear panels, it also adds natural lighting indoors.  You can watch a video of the system at work here .
