Most heat pumps maintain an average useful life of 10-20 years, but researchers at the University of Stavanger in Norway (USN) and the University of Oslo believe that they have developed a new heat pump that will last up to 10,000 years . The new heat pump is comprised of many miniature heat pumps, as small as one cubic millimeter, that can be arranged in an array to create a larger unit that can be tall and thin or short and wide, offering flexible modularity for application in any area of a building. <a href="http://ad.doubleclick.net/jump/Inhabitat/Technology;article=articlename;kw=content1;sz=300x250;ord=123456789?"
ENQUêTE Troisième volet de notre série sur les laboratoires d'exception : aux Pays-Bas, une trentaine de chercheurs modifient les propriétés des matériaux pour accroître leur durabilité. Delft, ses canaux, sa faïence, Vermeer... et son université technologique, TU Delft, où travaillent près de 2 700 chercheurs. Dans une ambiance très internationale : 80 % d'entre eux sont d'origine étrangère !
Device fabrication and operation concept
Self-powered laptops and everlasting batteries could soon become a reality thanks to a new study from the Royal Melbourne Institute of Technology that measured a piezoelectric film’s capacity for turning mechanical pressure into electricity. Piezoelectricity is a phenomenon already at work in small devices such as cigarette lighters, which use a piezoelectric crystal to create a charge when struck by a spring-loaded hammer. Piezoelectric materials such as crystals or ceramics are nothing new , but this is an application with a greater scope for use.
The University of Technology in Sydney recently unveiled a new type of graphene nano paper that is ten times stronger than a sheet of steel. Composed of processed and pressed graphite , the material is as thin as a sheet of paper yet incredible durable — this strength and thinness gives it remarkable applications in many industries, and it is completely recyclable to boot. <a href="http://ad.doubleclick.net/jump/Inhabitat/;kw=content1;sz=300x250;ord=123456789?"
Scientists at Konkuk University , Seoul National University and the University of Edinburgh’s School of Chemistry have developed an energy-efficient device capable of storing the memory needed for smart phones, mp3 players and digital cameras.
C’est à pas de souris que semble avancer la collecte des DEEE (déchets d’équipements électriques et électroniques) ménagers.
Above: Scott Weaver came to Maker Faire to show how he makes incredible toothpick sculptures. The "1-10-100 principle" applies to his art, I'm sure.
