Snecma Tests Open Rotor Engine Snecma, the French engine manufacturer of the Safran group is working on an ‘open rotor’ engine that promises to cut fuel consumption and CO2 emission levels, and reduce acoustic signature powering the passenger airplanes in the 2030s. The goal of the current research is to test a jet engine that consumes 30% less fuel than today’s powerplants. This new type of engine comprises two distinct parts: a conventional gas generator, and a turbine driving two counter-rotating, unducted fans that will propel the aircraft. “An aircraft engine’s efficiency and consumption depend on the amount of air the fans draw and eject at slow speeds,” Snecma (Safran) Research & Technology Director Pierre Guillaume points out. “With the open rotor, we will be able to considerably increase that drawn air flow because we won’t have any ducting around the fans. And that will improve consumption and cut CO2 emissions.” There are still a number of challenges to tackle, starting with noise.
How to Solder Metals Together - Tool Tutorial Friday Wheee, it’s another episode of Tool Tutorial Friday! Do y’all miss TTF? I do too, but this handy gal only has so many tools in her toolbox. I added a new one a few weeks ago, a soldering iron. When I was in college, I took a stained glass elective (one of the benefits of going to art school.) As promised, here is the tutorial on how to solder. Materials: Soldering ironDamp spongeSolderFluxBrush for the fluxSandpaperPainter’s tapeDamp ragSafety glasses If you’ve used a curling iron, you are qualified to solder. Plug in the soldering iron and let it heat up. In the meantime, lightly sand the edges of the metal where they will be joined. Wipe off any sanding dust with a damp rag. Cover any areas that you don’t want exposed to solder with painter’s tape (like this light bulb socket.) Add flux to the areas that will be accepting the solder. Set up your work area so everything is within easy reach. Have a damp sponge accessible to wipe off any excess solder from the tip of your soldering iron. P.s.

Inside the aid bag of a U.S. Army combat medic The Truly Spectacular Process Of How The Best Chef's Knife In The World Is Made Made of stacked melted meteorite that looks more like Thor’s hammer and armed with the encyclopaedic knowledge of knives and stunning skill from bladesmith Bob Kramer, these chef Kramer knives are among the finest in the world. This video of him, by Anthony Bourdain’s Raw Craft, features his process and it might be the most impressive knife making video I’ve ever seen. And I’ve seen a lot! Kramer is one of only 122 certified master bladesmiths in the US and the only one who specialises in kitchen knives.
Greenland Is Building The Perfect Place To Watch The World End A stunning structure built 241km inside the Arctic Circle will serve as a crucial research centre for glaciologists. But perhaps more importantly, it will be a place where humans can travel to see the real-time impact of climate change.Images: Dorte Mandrup The Illulissat Icefjord is a UNESCO-protected site on Greenland’s west coast that’s known for both its stunning natural features and its long history of human habitation. Illulissat is one of the few spots where Greenland’s continental ice sheet calves into the sea, allowing scientists rare access to glacial ice that’s over 250,000 years old. This is why it’s known as climate change “ground zero”. People have been coming here to study the famously fast-moving Sermeq Kujalleq glacier for 250 years. The Icefjord Centre will provide a permanent outpost for this scientific work as well as an interpretive centre to help visitors understand it. The Icefjord Centre is planned to open in 2020, but will Greenland even have any ice then?
Bruder Exp-6 Expedition Trailer The appeal of getting out into nature and enjoying the majesty of it – the sheer size of open land, the wildlife, and the stars at night – is nearly universal. On the other hand, a tolerance for bigs, dirt, and not showering for a couple weeks is not. That’s where the Bruder Exp-6 Trailer comes in. Bruder has pushed the envelope with this trailer by melding rugged capability with luxury.
Wedgewood Damascus Steel & Bourbon Barrel Ring There are two options a jeweler has when putting a piece together; you can either use a material as a straightforward design element, or you can use a material that tells a story and helps create something that is more than the sum of its parts. Wedgewood Rings’ Damascus steel and bourbon barrel wood ring goes with the latter option. More than anything else, these rings are unique. Each one is individually made by a single artist based out of Denver, Colorado, making it so every one that Wedgewood sells is slightly different from the last. Consisting of a twisted damascus steel pattern laid over the buyer’s choice of wood sourced from a whisky barrel, each one has a totally different motif. For even more personalization, those who order get the choice of having the interior of the ring made from barrel wood sourced from distillers ranging from Makers Mark to Suntory Yamazaki.
Edgeland House by Bercy Chen Studio Inspired after the age-old Native American Pit House, this modern take on an old classic works to utilize a similar methodology behind the style: that is using the earth’s mass to maintain heat through the colder months of the year. Think of it as a warm blanket, keeping heat maintained within the walls of the home. Dubbed the Edgeland House, it’s a well-respected project by Bercy Chen Studio. It boasts a roof full of growth and extends seven feet underground. The result is a warm household during the colder months and cooler dwelling in the summer. H3 House by Luciano Kruk Built upon a modest 688 square foot plot of land in the woodsy terrain of coastal Buenos Aires, the H3 house, designed by Argentinian architecture firm Luciano Kruk, was conceived as a summer home for three sisters and each of their families. It’s located in Mar Azul, literally translating to “blue sea,” so it’s obvious why the investment was made in the area. H3 hosts two social areas with one being a bit more private, along with a master bedroom and a smaller “cabin-like” one that share a Jack and Jill bathroom.
