These Color-Changing Tattoos Monitor Your Health, No Wearable Needed

These Color-Changing Tattoos Monitor Your Health, No Wearable Needed | 21st Century Craft & Pride | Scoop.it
Researchers are getting closer to turning the skin into an interface, while designers imagine what these interfaces might look like. Do they come in the form of a tattoo, like Vega suggests, or a temporary tattoo that doubles as a circuit? Do they act like a second skin? Will we use them to control our devices, or to better understand our bodies? Either way, there’s a whole lot more to explore on the surface of our skin.
Vivalist's insight:
What if your tattoo could also be an accurate indicator of your blood sugar level or other medical variables some need to check on a regular basis...

No wearables needed... well, it's the ultimate wearable I guess. Permanent.

Scientists turn hydrogen into metal in breakthrough that could revolutionise the planet | 21st Century Craft & Pride | Scoop.it
Scientists at Harvard University succeeded in creating a tiny amount of the rarest, and possibly most valuable, material on the planet
Vivalist's insight:
I thought graphene would be the next revolution

But itlooks like we now have a contender as Harvard University researchers have found a way to pressurize Hydrogen into a metal that would be stable after pressure is released.

It is exciting to see more and more new materials with super-properties made available. Plastic made of orgnaic materials also have a bright future.

World's first pocket spectrometer lets you measure the molecular makeup of nearly anything

World's first pocket spectrometer lets you measure the molecular makeup of nearly anything | 21st Century Craft & Pride | Scoop.it
Equipped with some of the capabilities of large, heavy laboratory spectrometers, but built around the kind of optics used in cell phone cameras, the SCiO measures the light reflected off any given object, breaks down its spectrum, and then sends that information to the cloud. Consumer Physics‘ unique algorithms immediately interpret the resulting data and the results show up on your cell phone within 5 seconds on a 3G connection.
Vivalist's insight:
mind blown. I've been dreaming of this for a long long time. Hopefully, it isn't a poor capacity sensors and, along with the thermal cams for smartphone and other affordable sensors, this brings physics and chemistry measurements to everyone.

It is affordable (around 300$) compared to "normal" spectrometers... and it is possible to get a SDK (not free though) in order to integrate it in mobile apps :)

Artificial Spinal Cord Wirelessly Restores Walking in Paralyzed Monkeys

Artificial Spinal Cord Wirelessly Restores Walking in Paralyzed Monkeys | 21st Century Craft & Pride | Scoop.it

By implanting a wireless neural prosthetic into the spinal cord of paralyzed monkeys, a team led by Dr. Grégoire Courtine at the Swiss Federal institute of Technology (EPFL) in Lausanne, Switzerland achieved the seemingly impossible: the monkeys regained use of a paralyzed lower limb a mere six days after their initial injury without requiring any training.


Via Sílvia Dias
Vivalist's insight:
'The close-looped [untethered] system directly reads signals from the brain in real-time and works on the patients’ own limbs, which means it doesn’t require expensive exoskeletons or external stimulation of the patient’s leg muscles to induce the contractions necessary for walking. That’s huge: it means the system could be readily used by patients in their own homes without doctor supervision.'

'Going from monkeys to humans requires a bit more work. Unlike monkeys that use all four limbs to walk, we’re bipedal. And real-world injuries are often messier than the surgically induced lesions in the study, which only damaged one leg. That said, in humans with incomplete spinal cord damage, there’s a lot of circuitry that survives and could be commandeered for the system to work on. “It seems quite feasible that a similar technique could be used to generate walking in an individual who has both legs paralyzed,” says Andrew Jackson from the Institute of Neuroscience in Newcastle UK.

Forest-powered biofuel flight heads to Washington, D.C. - Washington State University

Forest-powered biofuel flight heads to Washington, D.C. - Washington State University | 21st Century Craft & Pride | Scoop.it

SEATTLE – Washington state-based Alaska Airlines today made history flying the first commercial flight using the world’s first renewable, alternative jet fuel made from forest residuals, the limbs and branches that remain after the harvesting of managed forests. The alternative jet fuel was produced through the efforts of the Washington State University-led Northwest Advanced Renewables Alliance (NARA). The demonstration flight departed Seattle-Tacoma International Airport this morning for Reagan National Airport in Washington, D.C. The flight was fueled with a 20 percent blend of sustainable aviation biofuel, which is chemically indistinguishable from regular jet A fuel. 

Vivalist's insight:
if the process doesn't lead to over-exploitation of the forest resources, then this could ease one of the transition obstacles: air traffic

Simple, inexpensive method for creating energy-harvesting wooden floors

Simple, inexpensive method for creating energy-harvesting wooden floors | 21st Century Craft & Pride | Scoop.it
electricity is generated through cellulose nanofibers less than a millimeter thick, which are embedded into the wooden flooring. Some of these nanofibers are chemically treated, and when they're brought into close contact with the untreated nanofibers through vibrations caused by footsteps on the surface of the material, they produce an electric charge. This can then be harvested to power lighting, charge batteries, or for other household needs, and the system's energy output could be increased by building in several layers.
Vivalist's insight:
yest another experimentation on energy-harvesting. It is not clear what kind of "power" could be generated amp-wise but it is still an encouraging step toward more alternatives to conventional electricity production.

And it also has the huge advantage of costing little to no extra money in comparison with a "normal" wooden floor as the nano-fiber wouldn't cost much and their integration to the wood pulp wouldn't require extra engineering.

Solar Capture Technique Turns CO2 Into Burnable Fuel

Solar Capture Technique Turns CO2 Into Burnable Fuel | 21st Century Craft & Pride | Scoop.it
In a new paper published in Science, engineer Amin Salehi-Khojin and colleagues describe the new system, which can turn CO2 into fuel at a cost that’s comparable to producing gasoline.
Vivalist's insight:
"To make it work, the researchers used a photosynthetic cell, as opposed to a conventional photovoltaic cell. So instead of converting sunlight into electricity and then storing that energy in batteries, the new device converts atmospheric carbon dioxide directly into fuel. In essence, it does the work of plants. But instead of turning fuel into sugar, the “artificial leaf” delivers synthetic gas, or “syngas,” which is a mixture of hydrogen gas and carbon monoxide. This solar-produced gas can be burned directly, or converted into other forms of fuel, like diesel."

SO yes, it would encourage the use of diesel which is not a "clean" energy, but it would do so in a much cleaner way than most energy production means - so I guess it is good news.

Over-Unity Reactionless Generator Invented In India

Over-Unity Reactionless Generator Invented In India | 21st Century Craft & Pride | Scoop.it
A Reactionless AC Synchronous Generator (RLG) has been invented by Paramahamsa Tewari, electrical engineer and former Executive Director of Nuclear Power Corporation of India.
Vivalist's insight:
Dated April 2015, this article is pointing to what could be one of the biggest breakthrough of the century.

"[the author] believe, as do the engineers in India, that this is the biggest breakthrough in rotating electrical machine design since Faraday’s invention of the electrical motor in 1832. [...] Current models can be cascaded for higher output. Each machine can produce at least 2.38 times the input and can be configured in a self-running mode."

"The RLG is based on an understanding of the non-material properties of space. Paramahamsa Tewari’s search for the nature of reality has led him from study of the ancient Vedas of India to the formulation of Space Vortex Theory.

It is a new theory unifying the relationship between space, mass, inertia, light, and gravity. Starting with principles described in the Vedic texts, Tewari was able to delineate a mathematical model that explains the words of Tesla when he said:

'All perceptible matter comes from a primary substance, or tenuity beyond conception, filling all space, the akasha or luminiferous ether, which is acted upon by the life giving Prana or creative force, calling into existence, in never ending cycles all things and phenomena.' – Nikola Tesla,“Man’s Greatest Achievement,” 1907"

This incredible soft robot needs no batteries or computer chips

This incredible soft robot needs no batteries or computer chips | 21st Century Craft & Pride | Scoop.it
Researchers use an ingenious design to make a soft robot that moves on its own.
Vivalist's insight:
According to the Harvard researchers who created it, it’s the first soft robot that is completely self-contained. It has no hard electronic components—no batteries or computer chips—and moves without being tethered to a computer.

The alternating release of gas produced by catalyze of hydrogen peroxide hitting platinum is what makes the bot do what looks like a little dance, wiggling its tentacles up and down and moving around in the process. The octobot can move for about eight minutes on one milliliter of fuel.

Still missing are sensing and programming abilities that would afford more control over the robot’s movement. But the octobot is purposefully minimalist, meant just to show that such a soft robot can be made at all.

Researchers convert CO2 into biofuel

Researchers convert CO2 into biofuel | 21st Century Craft & Pride | Scoop.it

Researchers from the Ulsan National Institute of Science and Technology (UNIST) in South Korea have developed methods to make biofuels from carbon dioxide (CO2) which could power trucks and buses.

Professor Jae Sung Lee published [a paper] in the journal Applied Catalysis B: Environmental, [which] demonstrates it is possible to 'direct CO2 conversion to liquid transportation fuels by reacting with renewable hydrogen (H2) generated by solar water splitting'.

Professor Lee said the new mineral (delafossite-CuFeO2) catalyst converts CO2 into liquid hydrocarbon-based fuels offering a new opportunity for recycling CO2 into valuable fuels and chemicals.

Google’s Project Sunroof Expands to 42 States and Millions More Rooftops

Google’s Project Sunroof Expands to 42 States and Millions More Rooftops | 21st Century Craft & Pride | Scoop.it
Project Sunroof works by using high-resolution aerial imagery from Google Earth to help calculate a roof’s solar energy potential. Potential customers simply need to enter their address, and in roughly one second the program analyzes factors such as shade, roof orientation and local weather patterns to calculate how many hours of sunlight hit that roof in a typical year. All of this information is combined to create an estimate for how much the household could potentially save by going solar over the term of a 20-year lease.

Users can fine-tune the estimate by entering their electricity bill information. They can also view savings estimates for different financing options, including a loan and direct purchase. Potential customers can then click to see solar providers in their area.

Project Sunroof currently hosts a mix of solar companies, including major players like SunPower, local installers like Verengo Solar and new players like Pick My Solar. Interested customers can choose to share their contact information with selected providers on the Sunroof platform or contact them directly.
Vivalist's insight:
Google's Project Sunroof now extend to most of the United States. I wonder if Elon Musk's Solar City will join the project :)
If they did, it certainly won't be with a standard deal.
