The antenna is made by using organic dyes that are excited by light. The dyes then relax and emit more silicon-friendly photons. The dyes are embedded in a hydrogel that keeps them separated but densely packed. After being warmed up and cooled down, it creates a thin pink film that can be coated on top of solar cells, potentially doubling the efficiency.
Even better is that the materials are all biological and non-toxic -- even edible -- and the chemistry to make the film is simple.
"It can be done in the kitchen or in a remote village. That makes it inexpensive to produce," said Kumar.
The researchers are already working with a Connecticut company to figure out how to apply the coating to commercial solar cells. The team is also looking at how the same hydrogel technology can be used to improve drug delivery within the human body and white LEDs.
that's interesting... an easy to produce and clean way to enhance solar panels capabilities
The era of true nuclear fusion may be fast approaching thanks to some cutting-edge work from MIT. While fusion has been demonstrated before, it's always used more energy than it's created. But finding a new way to apply a strong magnetic field to a prototype device, the MIT team has learned how to better contain super-hot plasma, and that's a step towards practical application.
A fusion reactor works like a mini-star, fusing hydrogen atoms into helium just as the sun does. But without the immense gravity of a star, the plasma escapes, requiring more energy to keep it in place. This new magnetic field keeps the core together, and maximizes the energy output of the tiny star.
Promising solution of nuclear generated power - yet increasing the demand for rare-earth so it is just pushing the dust deeper under the carpet I guess.
Social media company plans to start testing the craft, which is intended to provide internet access to remote areas, within months
"Aquila is a solar powered unmanned plane that beams down internet connectivity from the sky. It has the wingspan of a Boeing 737, but weighs less than a car and can stay in the air for months at a time.
We've also made a breakthrough in laser communications technology. We've successfully tested a new laser that can transmit data at 10 gigabits per second. That's ten times faster than any previous system, and it can accurately connect with a point the size of a dime from more than 10 miles away."
That's money well spent. Imressive innovation. Hope it doesn't collide with Google's Loon balloon :)
The next billion devices may be powered from thin air, according to a team of researchers from the University of Washington
very interesting project by University of Washington researchers Shyam Gollakota and his team: PoWiFi ‘tricks’ routers into sending out constant RF signals received by an antenna. This is then converted into DC power with a ‘rectifier.’ A DC-DC converter increases the voltage to fit the sensor and microcontroller’s requirements.
As they report in the science journal PLOS, Michael Levin and Daniel Lobo, two computer scientists/biologists at Tufts University, have programed a computer that independently created its own scientific theory. It's one that may solve a 120-year-old mystery in biology that has eluded even our best explanations: exactly how the genes of a sliced-up flatworm conduct its symphony of cells when they regenerate into new organisms.
Levin and Lobo are quite adamant that what they programed their computer to do "is not just statistics or number-crunching," says Levin. Through trail and error, the computer invented an accurate model of the inner-workings of the flatworm. "The invention of models to explain what nature is doing is the most creative thing scientists do. . . this is the heart and soul of the scientific enterprise," he says. "None of us could have come up with this model; we (as a field) have failed to do so after over a century of effort."
exciting time ahead. Computers won't complain about research funding cuts ;) Joke apart, they are non human so less prompt to error and bias - being honest errors of judgement or plain corruption by research funders.
MIT researchers have developed a wireless touchpad small enough to fit on your fingernail. Dubbed NailO, the prototype is modeled after cosmetic nail stickers. It squeezes a capacitive sensor, microcontroller, Bluetooth radio, and battery into a footprint no larger than a quarter. The idea is to provide an alternative input mechanism for wearables and situations that don't map well to conventional control schemes.
Carbon3D lives at the intersection of hardware, software and molecular science. Our CLIP technology allows commercial customers to go beyond basic prototyping with conventional 3D printing to truly achieve 3D manufacturing.
That's it, the "real" 3Dprinting is here. It works around many of 3D printing limitations (time to produce, materials and their mechanical properties...)
In what is a giant leap towards true general artificial intelligence, Google scientists and engineers have created the first ever computer program that is capable of learning a wide variety of tasks completely independently.
the video where you actually see the learning happening in front of you is moving. Yet oh so scary!
The power of sunlight and the heat it gives off, the power of the wind, the power of the waves, the energy that makes plants grow, the water that falls under the force of gravity, what about the power of evaporation? Just another way mankind is learning to harness the energy that makes our world go....
Columbia University researchers experiment with a spore that contract and expand when the environment is dry or humid, harnessing the energy produced by the reaction. It is a very small scale project, but could have unexpected positive impact.
Shawyer [UK aerospace engineer who first came with the idea) has often been dismissed by the research establishment for not having peer-reviewed scientific publications, but White and Tajmar have impeccable credentials that put them beyond cheap dismissal and scorn. Physics is an experimental science, and the fact that the EM Drive works is confirmed in the lab. "This is the first time that someone with a well-equipped lab and a strong background in tracking experimental error has been involved, rather than engineers who may be unconsciously influenced by a desire to see it work," notes Wired referring to Tajmar's work.
tada! take that "science"! This is groundbreaking tech in order to explore space, but it could also revolutionize terrestrial transportation
Today, Microsoft has published a new video highlighting HoloLens and their partnership with Case Western Reserve University. The deal between the two institutions was announced back at Build along with a demonstration on stage. Based in Cleveland, Ohio, Case Western Reserve University is a private research university who plans to use HoloLens to teach anatomy and solving human problems...
Microsoft announced a partnership with a university in order to promote the use of HoloLens for medical studies. Holographic imagery put to good use :)
AND, they get to be more realistic about the field of view that HoloLens actually provide - which is quite narrower than what they communicated on in the past.
I've watched a lot of handsomely paid CEOs get on stages for keynote presentations over the past decade, and none were as good as the one I saw Elon Musk give Thursday night in California as he introduced Tesla's new battery system. I'm sure many people will disagree — I mean, how can you compete with Steve Jobs introducing the iPhone in 2007 — but ultimately Jobs was selling a better smartphone. Musk is selling a better future.
clocking at 17 :57 (with applause, laughter and cheers included)
Elon Musk just presented what will be the most disruptive tech of the 21st century. I've known for a long time that cars were just the beginning, but to see him explain how his company is actually going to roll out its plan for a better world is heart warming.
Aerospace and defense company Boeing recently earned a patent for its first ever force field. The design, submitted to the United States Patent and Trademark Office as a "method and system for shockwave attenuation via electromagnetic arc," could be the next step toward Star Wars-style military tactics, creating a brief plasma field to soak up potentially damaging shockwaves.
