Image: Wristify Here’s a scary statistic: In 2007, 87 percent of households in the U.S. used air conditioning, compared to just 11 percent of households in Brazil and a mere 2 percent in India. Another one: By 2025, booming nations like those are projected to account for a billion new consumers worldwide, with a corresponding explosion in demand for air conditioning expected to arrive along with them. Keeping indoor spaces at comfortable temperatures requires a huge amount of electricity–especially in sweltering climates like India and Brazil–and in the U.S. alone it accounts for a full 16.5 percent of energy use.
All of that adds up to a big problem. At a point when humans need to take a sober look at our energy use, we’re poised to use a devastating amount of it keeping our homes and offices at the right temperatures in years to come. Shames runs hot. Shames runs hot. The team’s now turning to refining the design. 8 inventions techno-écolo ! Des végétaux très au courant Produire de l’électricité avec… de la mousse ! C’est ce qu’ont réalisé des designers et scientifiques de l’université de Cambridge. Utilisant la technologie Biophotovoltaïque (BPV), la Moss Table capte l’énergie produite par la mousse lors de sa photosynthèse, la stocke dans une batterie et la redistribue sous forme d’électricité pour alimenter la lampe intégrée au meuble.
Si la mousse ne produit actuellement que 50 milliwatts / m2, les scientifiques espèrent atteindre une production électrique de 3 w/m2. La Moss Table pourrait alors alimenter un ordinateur portable pendant 14h00. www.cam.ac.uk Romain Dondelinger Diplômé de l'École Française de Journalisme (EFJ) et après plusieurs expériences dans des chaînes de télévision, Romain s'envole pour l'Australie.

Synthetic living creatures would be released into the wild to save endangered species and clean up pollution under this futuristic proposal by designer Alexandra Daisy Ginsberg (+ slideshow + interview). Called Designing for the Sixth Extinction, the project is designed to trigger debate about how artificial organisms could be used to solve environmental problems.
"I'm looking at how we could do rewilding using synthetic biology," said Ginsberg. "The idea is that we could preserve or maintain a state of nature using synthetic organisms that are designed to save other species. " Ginsberg has proposed four new species, including a slug that leaves a trail of alkali to neutralise acidic soil, and a porcupine with sticky rubber spines that would help disperse seeds of threatened plants. There is also an artificial puffball that kills tree-damaging pathogens when it bursts; and a biofilm that grows on leaves and absorbs pollutants and viruses, safely removing them when the leaves fall in autumn. Led Mushroom par Yukio Takano. Des champignons dans une maison, un bureau … c’est jamais très bon signe. Sauf quand il s’agit de champignons que l’on dirait tout droit sortis d’un conte fantastique et qu’ils sont destinés à illuminer votre bureau.
Le designer japonais Yukio Takano a imaginé un concept eco-design de lampe de bureau dénommé Led Mushroom. Portant un certain intérêt aux champignons, Yukio Takano a réalisé cette série de lampes à la fois amusantes et très réalises représentant des champignons poussant sur des souches de bois. Les champignons sont réalisés en matière synthétique et sont incrustés de LED pour offrir une petite lumière d’ambiance.
La base en bois sur laquelle il repose, abrite une batterie qui va servir à alimenter le dispositif en énergie et un bouton marche / arrêt.

Engineer Jim Kor and his design for the Urbee 2. Photo: Sara Payne Picture an assembly line not that isn’t made up of robotic arms spewing sparks to weld heavy steel, but a warehouse of plastic-spraying printers producing light, cheap and highly efficient automobiles.
If Jim Kor’s dream is realized, that’s exactly how the next generation of urban runabouts will be produced. His creation is called the Urbee 2 and it could revolutionize parts manufacturing while creating a cottage industry of small-batch automakers intent on challenging the status quo. Urbee’s approach to maximum miles per gallon starts with lightweight construction – something that 3-D printing is particularly well suited for. Jim Kor is the engineering brains behind the Urbee.
“We thought long and hard about doing a second one,” he says of the Urbee. Kor and his team built the three-wheel, two-passenger vehicle at RedEye, an on-demand 3-D printing facility. Photo: Sara Payne “We’re calling it race car safety,” Kor says. New Invention Makes Ocean Water Drinkable.
Susanne Posel Occupy Corporatism July 2, 2013 Chemists with the University of Texas and the University of Marburg have devised a method of using a small electrical field that will remove the salt from seawater. Incredibly this technique requires little more than a store-bought battery. Called electrochemically mediated seawater desalination (EMSD) this technique has improved upon the current water desalination method. Richard Cooks, chemistry professor at the University of Austin said : “The availability of water for drinking and crop irrigation is one of the most basic requirements for maintaining and improving human health.”
Cooks continued: “Seawater desalination is one way to address this need, but most current methods for desalinating water rely on expensive and easily contaminated membranes. Kyle Krust, lead author of the study said: “We’ve made comparable performance improvements while developing other applications based on the formation of an ion depletion zone.

Newlight Technologies co-founder Mark Herrema shows off AirCarbon pellets | Image credit: Dan MacMedan/USA TODAY We’re hearing more and more often about inventive new ways companies are turning waste into valuable resources — from turning everything from CO2 and methane gases to human and food waste into fuels, and plastic into bacteria-battling “ninja polymers.” This week USA Today explored another breakthrough — a process that extracts carbon molecules from methane gas and turns them into plastic. California-based startup Newlight Technologies is using captured methane gas from dairy farms and turning it into AirCarbon, a durable and versatile plastic that can be used in everything from furniture and food containers to auto parts.
According to the article, AirCarbon removes more carbon from the atmosphere than its manufacturing emits, making it a carbon-negative material. Already in the works? Compostable Material to Replace Plastic? Credit: Courtesy of Zeoform Cellulose is the most pervasive natural polymer on the planet. As the primary structural material in plants, it is essentially a long chain of connected sugars. We encounter cellulose in consumer goods such as textiles and wood pulp, in the form of paper. However, the Australian company Zeoform has figured out how to turn the soft, fibrous material into a hard plastic. Made from nothing but cellulose fibers and water, Zeoform is promoted by its namesake company as “the world’s new plastic”—a nontoxic, compostable, and environmentally favorable alternative to petroleum-based plastics.
The cellulose-based material used to fabricate this coffin will biodegrade is less than a year without protective coatings, its maker Zeoform says. Sourced from the fibers of recycled waste paper, Zeoform exhibits characteristics of plastic and wood.

Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010,[1] and is expected to increase about 3.1% each year for the next 25 years. Hydropower is produced in 150 countries, with the Asia-Pacific region generating 32 percent of global hydropower in 2010. China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010, representing around 17 percent of domestic electricity use.
There are now four hydroelectricity stations larger than 10 GW: the Three Gorges Dam and Xiluodu Dam in China, Itaipu Dam across the Brazil/Paraguay border, and Guri Dam in Venezuela.[1] The cost of hydroelectricity is relatively low, making it a competitive source of renewable electricity. The Solar Energy Timeline. Innovative Wind Turbine Smaller Than a Penny Could Power Your Smartphone.
Researchers at the University of Texas at Arlington have developed a renewable energy technology smaller than our smallest form of currency, yet capable of charging smartphones. The micro-windmills designed by electrical engineering professor Dr. J. -C. Chiao and research associate Smitha Rao are so tiny that a single grain of rice could hold about 10 of them, according to a news release from the university.
The duo envision embedding hundreds of micro-windmills in a sleeve for a cell phone. “Imagine that they can be cheaply made on the surfaces of portable electronics,” Chiao said, “so you can place them on a sleeve for your smart phone. “When the phone is out of battery power, all you need to do is to put on the sleeve, wave the phone in the air for a few minutes and you can use the phone again.” Taiwanese fabrication foundry WinMEMS Technologies is exploring ways to commercialize the turbines.
At its widest point, one of the micro-turbines measures 1.8 millimeters. Gravity Battery Concept. The Crystal Cell - turning coherent quantum flu. BLP | Electrical Power from Water Vapor Fuel. Power plant claims to produce hydrogen by splitting water with sunlight. The plant would use an array of mirrors to focus sunlight onto a huge towerThe tower heats up to 1,350 °C - enough to liberate hydrogen from steamScientists describe the process as the Holy Grail of a hydrogen economy By Ellie Zolfagharifard Published: 18:07 GMT, 1 August 2013 | Updated: 11:31 GMT, 14 November 2013 Scientists believe they have achieved the ‘holy grail’ of the green economy by designing a hydrogen production plant that can split water with sunlight.
The University of Colorado at Boulder envisages an array of mirrors that would focus sunlight onto a central tower several hundred feet tall. The tower would heat up to around 1,350 °C - enough to liberate hydrogen from steam with the help of a metal oxide compound. A concept design of a hydrogen production plant that could fuel a sustainable green economy with sunlight and water. An array of mirrors focuses sunlight onto a central tower several hundred feet tall. This frees up hydrogen molecules for collection as hydrogen gas. Energy-producing shell covered with hairs that can extract wind energy. Belatchew Architects presents a visionary idea called STRAWSCRAPER, the first project to come out of their business called Belatchew Labs. STRAWSCRAPER is an extension of the south tower on Södermalm in Stockholm with a new energy-producing shell covered with hairs that can extract wind energy.
What was originally meant to be 40 storeys became only 26. The South Tower on Södermalm in central Stockholm was completed in 1997, but the architect Henning Larsen had then dropped out of the mission after having lost control over the design of the tower. Belatchew Architects want to give South tower its original proportions and at the same time explore new technologies to create the future of urban wind farming. Furthermore, an additional aspect is revealed when the constant movement of the straws creates an undulating landscape on the facades. We're One Step Closer to Nuclear Fusion Energy - Wired Science.
