Comments Off on New smart grid solution heals itself amid central grid outages

Renewable energy may offer emissions-free electricity , but it isn’t always easy for electrical grids to integrate that energy. Dutch company Alfen is launching their answer to the dilemma. The Cellular Smart Grid Platform (CSGriP) allows a central grid to be divided into smaller cells that can operate independently, if necessary, and even self-heal . CSGriP provides energy from sources like biogas , solar power , or wind power for local consumers. It includes “a 0.5 megawatt energy storage system and complex algorithm used for local energy management.” Should the central grid go out, local cells would take over to restore power for local customers. According to Alfen, “Once the grid balance within a cell is restored, it automatically reconnects to other cells, and, as such, quickly rebuilds the larger power grid” to reduce the duration of central grid outages. Related: INFOGRAPHIC: How a smart electric grid could reduce emissions by 58 percent in the US Alfen energy storage specialist Evert Raaijen said in a statement, “Unique about this solution is that the local cells are intrinsically stable through self-adjustment of supply and demand based on the frequency of the electricity grid. This makes the grid truly self-healing in cases of central grid outages. The self-healing mechanism based on frequencies sets it apart from many IT-related smart grids that require relatively vulnerable data and ICT connections for balancing local grids.” In developed countries, the point of the platform is to decentralize the grid and make it more ready for renewables. But the platform could also be deployed in developing countries that still need to be electrified, allowing them to avoid constructing central grids obtaining power from large fossil fuel -burning plants in favor of these local cells with storage systems for renewable sources. Alfen has worked in countries from the United Kingdom to the Czech Republic to Nigeria, on projects for electric vehicle charging , transformer substations, energy storage, smart grids, and grid automation. They are currently field testing CSGriP at the Application Center for Renewable Resources in Lelystad, the Netherlands . + Alfen Via Alfen Images via Alfen on Twitter ( 1 , 2 )

Comments Off on This pop-up prefab cocoon can immerse you in the heart of nature

Immersing yourself in nature without leaving the comfort of the hotel room may sound too good to be true, but that’s exactly what French architect and civil engineer Christophe Benichou sets out to achieve in LUMISHELL . Created in the shape of a cocoon, this prefabricated curved dwelling blurs the distinction between indoor and outdoor space with LUMICENEs, a patented reversible window concept. The LUMISHELL is designed for placement in a variety of exotic environments—even in Salar de Uyuni, the world’s largest salt flat that experiences below freezing temperatures. Clad in a protective aluminum skin, the 40-square-meter LUMISHELL comprises all the needs for a comfortable, long-term stay including a bedroom, bathroom, kitchen, and living room. The bedroom and living room are located at opposite ends of the curved dwelling and wrapped by LUMICENE , a curved glass sliding door that opens up to transform the room into an outdoor space. Curtains attached to the LUMICENE rails allow for privacy and protection from solar gain, while the shape of the structure is optimized for natural cross ventilation. Related: Cover installs its first prefab dwelling “for the masses” in L.A. “Both rooms provide unique panoramic views and can be occasionally transformed into outdoor spaces to enhance the feeling of being transplanted in the middle of vast scapes,” wrote the architect. “Various mirrors also create reflections that diffuse the landscape in the heart of the dwelling.” The self-supporting and prefabricated LUMISHELL can be assembled on site in as little as four days—not including hookups—and does not require foundations. The LUMISHELL is currently available for pre-orders and is expected to ship out for first installations in 2018. + LUMISHELL

E. coli bacterial evolution can be accelerated with the MAZE technique to produce favorable mutations Bacteria are prolific replicators, and some species can replicate into the millions in number in just a few hours. Bacteria, in the functioning of their cellular and biochemical machinery, also just happen to manufacture some very useful chemicals and bio-active molecules.

9500 Liberty Documentary Fuels Immigration Debate

Comments Off on 9500 Liberty Documentary Fuels Immigration Debate

For anyone who has seen the original Invasion of the Body Snatchers , they might get that same feeling of “us” versus “them” that fills the truly indie 9500 Liberty . Body Snatchers grabbed its content and texture from the red scare, the McCarthy era where people believed that Communists (or rather aliens) launched an invasion of the small town. 9500 Liberty takes that same feeling with a Virginia town that according to some locals has been invaded by Zapatistas but the scary thing here is that the film here is a documentary.

Comments Off on The Danger of Staring too Close at 350

The International Day of Climate Action last Saturday saw the power of grassroots activism leveraged by new media and social networking. Through an online and viral campaign, Bill Mckibben’s climate action group  350.org inspired an international response of more than 5,200 events in 181 countries. Hailed as the “most widespread day of environmental action in the planet’s history,” the action focused on a single number: 350.
