this is a fridge, you put your shit in the gel and it keeps it cool, than you just reach in and take it out. the gel automatically reforms.

WTF

what happens if someone falls in

then they freeze and 1000 years passes and they fall out and get a cyclops for a girlfriend

Ok but like, germs n stuff.

Doesn’t actually exist, but is a design concept.

If you look at the bigger images on that page, you can see that the “groceries” (which include whole fish?????) are just flat images shooped in there for aesthetics/to show the concept.

Also, nanorobots.  This is just the kind of thing my particular Art & Tech professors would’ve gotten all wet over.

Huffington Post Religion is proud to announce that our 2012 Person Of The Year is Balpreet Kaur.

Ms. Kaur became an internet sensation when a photo of her standing in a line was taken by an editor at Reddit (a ‘Redditor) who posted it online under the subject heading ‘funny,’ apparently based on her unique appearance.

Balpreet Kaur responded to the intentional denigration by explaining who she was, why she looked the way she does, and the tenets of her Sikh faith with a remarkable generosity of spirit:

“Yes, I’m a baptized Sikh woman with facial hair. Yes, I realize that my gender is often confused and I look different than most women. However, baptized Sikhs believe in the sacredness of this body – it is a gift that has been given to us by the Divine Being [which is genderless, actually] and, must keep it intact as a submission to the divine will… When I die, no one is going to remember what I looked like, heck, my kids will forget my voice, and slowly, all physical memory will fade away,” Kaur wrote. “However, my impact and legacy will remain: and, by not focusing on the physical beauty, I have time to cultivate those inner virtues and hopefully, focus my life on creating change and progress for this world in any way I can.“

Hot-Fire Tests Show 3-D Printed Rocket Parts Rival Traditionally Manufactured Parts

What can survive blazing temperatures of almost 6,000 degrees Fahrenheit without melting? What did not break apart at extreme pressures? What is made by a new process that forms a complex part in just one piece? What takes less than three weeks to go from manufacturing to testing? What can reduce the costs of expensive rocket parts by 60 percent or more?

Answer: 3-D printed parts

Engineers know that 3-D printed rocket parts have the potential to save NASA and industry money and to open up new affordable design possibilities for rockets and spacecraft. But until recently, no one had tested rocket parts critical to engine combustion in a hot-fire environment.

NASA engineers at the Marshall Space Flight Center in Huntsville, Ala., not only put rocket engine parts to the test but also were able to compare their performance to parts made the old-fashioned way with welds and multiple parts during planned subscale acoustic tests for the Space Launch System (SLS) heavy-lift rocket. In little more than a month, Marshall engineers built two subscale injectors with a specialized 3-D printing machine and completed 11 mainstage hot-fire tests, accumulating 46 seconds of total firing time at temperatures nearing 6,000 degrees Fahrenheit while burning liquid oxygen and gaseous hydrogen.

“We saw no difference in performance of the 3-D printed injectors compared to the traditionally manufactured injectors,” said Sandra Elam Greene, the propulsion engineer who oversaw the tests and inspected the components afterward. “Two separate 3-D printed injectors operated beautifully during all hot-fire tests.”

Post-test inspections showed the injectors remained in such excellent condition and performed so well the team will continue to put them directly in the line of fire. In addition to the SLS acoustic tests, Greene and her team tested a more complex assembly of a 3-D printed injector and thrust chamber liner made by Directed Manufacturing, Inc., of Austin, Texas. Marshall engineers transferred a second 3-D printed injector to NASA’s Stennis Space Center in Mississippi, where it will continue to accumulate hot-fire time to test its durability.

“Rocket engines are complex, with hundreds of individual components that many suppliers typically build and assemble, so testing an engine component built with a new process helps verify that it might be an affordable way to make future rockets,” said Chris Singer, director of the Marshall Center’s Engineering Directorate. “The additive manufacturing process has the potential to reduce the time and cost associated with making complex parts by an order of magnitude.”

Traditional subscale rocket injectors for early SLS acoustic tests took six months to fabricate, had four parts, five welds and detailed machining and cost more than $10,000 each. Marshall materials engineers built the same injector in one piece by sintering Inconel steel powder with a state-of-the-art 3-D printer. After minimal machining and inspection with computer scanning, it took just three weeks for the part to reach the test stand and cost less than $5,000 to manufacture.

“It took about 40 hours from start to finish to make each injector using a 3-D printing process called selective laser melting, and another couple of weeks to polish and inspect the parts,” explained Ken Cooper, a Marshall materials engineer whose team made the part. “This allowed the propulsion engineers to take advantage of an existing SLS test series to examine how 3-D printed parts performed compared to traditional parts with a similar design.”

Since additive manufacturing machines have has become more affordable, varied, and sophisticated, this materials process now offers many possibilities for making every phase of NASA missions more affordable. The SLS injector tests are just one example of NASA’s efforts to fabricate and test 3-D printed parts in relevant environments similar to those experienced during NASA missions. The SLS injector test series complements a series of liquid oxygen and gaseous hydrogen rocket assembly firings at NASA’s Glenn Research Center in Cleveland, which hot-fire tested an additively manufactured, select laser melted injector developed through collaboration of industry and government agencies. A J-2X engine exhaust port cover made at the Marshall Center became the first 3-D printed part tested during a full-scale engine hot-fire test at NASA’s Stennis Center. Marshall materials engineers are currently making a baffle critical for pogo vibration mitigation; it will be tested at Marshall and Stennis and is a potential candidate for the first SLS mission in 2017. Marshall engineers are finishing up ground tests with Made in Space, a Moffett Field, California company working with NASA to develop and test a 3-D printer that will build tools on the International Space Station next year. NASA’s Johnson Space Center in Houston is even exploring printing food in space.

“At NASA, we recognize ground-based and in-space additive manufacturing offer the potential for new mission opportunities, whether printing rocket parts, tools or entire spacecraft,” Singer said. “Additive manufacturing will improve affordability from design and development to flight and operations, enabling every aspect of sustainable long-term human space exploration.”

NASA is a leading partner in the National Network for Manufacturing Innovation and the Advanced Manufacturing Initiative, which explores using additive manufacturing and other advanced materials processes to reduce the cost of spaceflight.
