Il conçoit une balle qui peut rendre 3 litres d’eau sale, potable!
Australie – Eau potable : M. Liow M. Jonathan de l’Université de Monash a conçu un petit appareil qui peut fournir jusqu’à 3 litres d’eau potable par jour en utilisant le principe d’évaporation comme moyen d’épuration! La Solarball est sûre et pratique. Les matériaux choisis sont conformes aux critères alimentaires, sont entièrement recyclables et lui offrent une longue durée de vie malgré des conditions environnementales difficiles. Comment ça marche? La sphère absorbe la lumière solaire afin que l’eau sale s’évapore. Les contaminants sont alors séparés de l’eau pendant que l’eau évaporée se condense en gouttelettes qui sont récupérées pour fournir une eau prête à boire. Toutes les pièces de l’appareil peuvent être produites en grandes quantités ce qui devrait diminuer les coûts de production, jusqu’à devenir accessibles aux pays qui manquent le plus d’eau potable! Le produit a été finaliste à l’Australian Design Awards 2011 – James Dyson Award.

De två ljusskenen kommer enligt rapporten från de områden där bränslet är placerat, och de mörka horisontella linjerna är skuggor av elektriska resistanser som används för att hålla igång reaktorn. Foto: Giuseppe Levi En större värmeproduktion än vad som är möjligt att förklara med kemiska reaktioner. Det rapporterar en grupp svenska och italienska forskare efter två mätningar om vardera fyra dygn på den kontroversiella energiapparaten E-cat. Det är fem svenska forskare från Uppsala och Stockholm samt två från Italien som tillsammans författat rapporten, tillgänglig sedan måndag morgon på sajten Arxiv.org.
Enligt rapporten var målsättningen att göra ett oberoende test under kontrollerade former och att använda mätinstrument med hög precision. – För att få mer kunskap om vad som försiggår måste vi se vad som har hänt med bränslet. . – Nästa test kommer att bli ett långtidstest.

Zep'lin concept design by Damien Grossemy Image Gallery (4 images) A boat that flies. Now there's a vehicle Phileas Fogg could really have used. Zep'lin is a blue-sky concept developed by industrial designer Damien Grossemy during a five month internship at Renault which imagines the use of solar panel sails and electric propulsion to liberate the yacht-like vehicle from terra firma. Setting out to "explore new design language of electric vehicles," Grossemy has come up with a land anywhere vertical architecture that incorporates a propeller drive, flexible wing and rudder system that would enable the craft to tilt sideways to make the most of the Sun's rays.

This article is reproduced from here. For some reason it has been taken down from his blog… I have the intention of writing this very post on this blog, and I may well still do so, but for now here is someone else’s… Just to be clear, this is not a scam! It is, however, a really good example of really sloppy journalism. Solar breakthrough? Some poor 13-year-old kid is all over the news as having made a “solar breakthrough”. Usual suspects: This is his writeup: [AMNH] The Secret of the Fibonacci Sequence in Trees Essential summary: This is, I’m sad to say, clear nonsense.

The actual power delivered by a solar cell is not linearly related to the open-circuit voltage; actually, as a semiconductor, it has a horribly nonlinear relationship.

La Rochelle va accueillir le premier véhicule urbain sans chauffeur au monde. Google et son véhicule robot n’ont qu’à bien se tenir. L’entreprise française Induct expérimentera bientôt son véhicule Cybergo, à conduite automatique et complètement autonome en énergie, en plein cœur de La Rochelle. Un face à face avec les américains Il faut dire que Cybergo a déjà un passif outre-Atlantique. La petite entreprise française a déjà tenté de se mesurer aux plus grands centres de recherche américains il y a quelques années à l’occasion des fameux concours de l’Agence de Recherche et Développement du Pentagone (DARPA). En 2005, elle était la seule équipe européenne à participer au DARPA Grand Challenge, une course de véhicules totalement autonomes sur un parcours de 200 km en plein désert de Mojave aux Etats-Unis.
Fort de ce succès, Induct a voulu poursuivre son odyssée et travaille depuis deux ans déjà sur la conception de véhicules électriques intelligents qui puissent être exploitables en milieu urbain. Running robots | Robotics. A cheetah running in its natural environment is an elegant, fluid display of biomechanics. What if robots could run the same way, and be deployed for search and rescue operations in areas where conventional vehicles cannot go? According to University of Delaware assistant professor Ioannis Poulakakis, a large fraction of the Earth's surface remains inaccessible to conventional wheeled or tracked vehicles, while animals and humans traverse such terrain with ease and elegance. He believes that legs have the potential to extend the mobility of robots, enabling them to become useful in real-world situations, such as search and rescue.
Poulakakis is the principal investigator of a three-year, $265,532 grant from the National Science Foundation (NSF) to develop a family of systematic control strategies that work together with the robot's natural dynamics to generate fast, reliable and efficient running motions. Under the grant, Poulakakis will develop: EurekAlert. CES 2012. Search. Grocery Stores on Wheels - Neighborhoods. The next wave of food trucks aren't whipping up Korean tacos for adventurous foodies or slinging ice cream to kids. Instead, they're delivering fresh meat and produce in an effort to improve public health in low-income communities. A few months ago, a Chicago non-profit launched Fresh Moves, a one-aisle grocery store on a bus that sells pineapples, mangoes, collard greens, onions and other fresh fruits and vegetables in West Side neighborhoods like Lawndale and Austin, where locals have minimal access to fresh produce.
A 2006 study by consultant Mari Gallagher linked these food deserts – defined by the USDA as a census tract more than a mile from a grocery store – to increased diabetes and other diet-related maladies, as well as premature death. Four Chicago residents developed the concept after deciding that opening their own grocery store or waiting for big retailers would take too long. They asked the city to donate one of its fleet to serve as a farmer's market on wheels.
