Within 10 years Planes Could Move Up To 10 Times The Speed Of Sound

An average flight from Miami to Seattle takes about six hours and 40 minutes, but imagine being able to reduce that time to 50 minutes or less. A recent study by NASA and Binghamton University researchers could lead to a drastic decrease in flight times. The study, funded in part by the U.S. Air Force, is one of the first steps toward the creation of planes able to move at hypersonic speeds, five to 10 times the speed of soundBinghamton University Associate Professor of Mechanical Engineering Changhong Ke explained that there are currently quite a few obstacles when it comes to building these super planes. The first of which is finding a material that can hold up to hypersonic travel.

Our study used what are called boron nitride nanotubes (BNNTs). NASA currently owns one of the few facilities in the world able to produce quality BNNTs.” Typically, carbon nanotubes have been used in planes for their strength — they’re stronger than steel — and their ability to conduct heat. However, BNNTs are the wave of the future when it comes to air travel. “While carbon nanotubes can stay stable at temperatures up to 400 degrees Celsius, our study found that BNNTs can withstand up to 900 degrees Celsius,” said Ke. BNNTs are also able to handle high amounts of stress and are extremely lightweight.

Withstanding high temperatures is an important requirement for any material meant to build the world’s next super planes, however, Ke clarified that the material has to be able to maintain both structural and mechanical properties in an oxygen environment. “We weren’t testing this material in a vacuum like what you would experience in space. Materials can withstand much higher temperatures in space. We wanted to see if BNNTs could hold up in the type of environment an average fighter jet or commercial plane would experience.”

While the study has brought new light to the strength and stability of BNNTs, their use on planes may not be a reality for another five to 10 years. “Right now, BNNTs cost about $1,000 per gram. It would be impractical to use a product that expensive,” added Ke. But, that does not mean it will never happen. Carbon nanotubes were about the same price 20 years ago. As more studies indicated the usefulness of carbon nanotubes, the production rates increased and prices went down to the current rate, between $10 and $20 per gram. Ke sees the same fate coming down the line for BNNTs.

Urban Farming At Home

Growing your own vegetables and herbs can be a laborious process. Lack of space in urban environments makes it even harder. But this smart garden is bringing the window box into the modern age. Much like Nespresso coffee capsules, users ‘plant’ this soil pod… containing the seeds and all the nutrients which are released in sync with the plant’s life cycle.


This is the plastic container they put the growing substrate in here. It has a wick solution, so basically it starts to drain the water from the water tank, and the lamp does the rest of the job. The lamp imitates daylight time, so it’s 16 hours on and 8 hours off. So far we have tested some 7,000 different plants and each growing substrate is designed specifically for this plant,” says Karel Kask, sales Manager, Click and Grow. Estonia-based ‘Click and Grow‘ says it’s tested up to a thousand lighting solutions to ensure optimal growth. The red and white lights deliver the perfect spectrum they say, speeding up growth by 30 to 50 percent, depending on the plant. Each soil pod provides up to 3 harvests. ‘Click and Grow‘ was inspired by NASA technology used to grow food in space. Here, astronauts aboard the International Space Station sample lettuce they’ve grown.

They’re using quite similar soil-based solutions; so they take the soil substrate into space and grow them already in there. They have an automated watering solution. So it’s quite similar to the solution that we do.The Smart Garden 9, its latest and most advanced model, was displayed at this week’s IFA tech fair in Berlin,” adds Kask.

How To Clean Up Space From Human-Made Debris

Right now, about 500,000 pieces of human-made debris are whizzing around space, orbiting our planet at speeds up to 17,500 miles per hour. This debris poses a threat to satellites, space vehicles and astronauts aboard those vehicles.

What makes tidying up especially challenging is that the debris exists in space. Suction cups don’t work in a vacuum. Traditional sticky substances, like tape, are largely useless because the chemicals they rely on can’t withstand the extreme temperature swings. Magnets only work on objects that are magnetic. Most proposed solutions, including debris harpoons, either require or cause forceful interaction with the debris, which could push those objects in unintended, unpredictable directions. To tackle the mess, researchers from Stanford University and NASA’s Jet Propulsion Laboratory (JPL) have designed a new kind of robotic gripper to grab and dispose of the debris, featured in the June 27 issue of Science Robotics.


There are many missions that would benefit from this, like rendezvous and docking and orbital debris mitigation,” said Aaron Parness, MS ’06, PhD ’10, group leader of the Extreme Environment Robotics Group at JPL. “We could also eventually develop a climbing robot assistant that could crawl around on the spacecraft, doing repairs, filming and checking for defects.”

Virtual Images that Blend In And Interact With The Real-World

Avegant, a Silicon Valley startup that sells a pair of headphones equipped with a VR-like portable screen, is breaking into augmented reality. The company today announced that it’s developed a new type of headset technology powered by a so-called light field display.


The research prototype, which Avegant eventually plans on turning into a consumer product, is based on the company’s previous work with its Glyph projector. That device was a visor of sorts that floats a virtual movie screen in front of your eyes, and developing it gave Avegant insight into how to build an AR headset of its own.

Like Microsoft’s HoloLens and the supposed prototype from secretive AR startup Magic Leap, Avegant’s new headset creates virtual images that blend in and interact with the real-world environment. In a demo, the company’s wired prototype proved to be superior in key ways to the developer version of the HoloLens. Avegant attributes this not to the power of its tethered PC, but to the device’s light field display — a technology Magic Leap also claims to have developed, yet has never been shown off to the public.

The demo I experienced featured a tour of a virtual Solar System, an immersion within an ocean environment, and a conversation with a virtual life-sized human being standing in the same room. To be fair, Avegant was using a tethered and bulky headset that wasn’t all that comfortable, while the HoloLens developer version is a refined wireless device. Yet with that said, Avegant’s prototype managed to expand the field of view, so you’re looking through a window more the size of a Moleskine notebook instead of a pack of playing cards. The images it produced also felt sharper, richer, and more realistic.

In the Solar System demo, I was able to observe a satellite orbiting an Earth no larger than a bocce ball and identify the Big Red Spot on Jupiter. Avegant constructed its demo to show off how these objects could exist at different focal lengths in a fixed environment — in this case a converted conference room at the company’s Belmont, California office. So I was able to stand behind the Sun and squint until the star went out of focus in one corner of my vision and a virtual Saturn and its rings became crystal clear in the distance.

The Glove That Gives You Super-Human Strength

The Bioservo or Soft Extra Muscles (SEM) glove mimics the human hand by using artificial tendons, motors and sensors for added muscle strength. The Swedish company is partnering with GMNASA to develop a glove to be used in manufacturing and other industrial applications.

GM-NASA Space Robot ‘Power’ Glove Finds New Life on EarthCLICK ON THE IMAGE TO ENJOY THE VIDEO

In 2012, General Motors and NASA developed a technology that could be used by both auto workers and astronauts aboard the International Space Station. Using actuators, artificial tendons, and sensors to mimic and multiply the function of the human hand, the battery-powered RoboGlove was designed to alleviate the stress and muscle fatigue of repetitive mechanical work in space. Now, according to The Verge, GM has licensed the RoboGlove to Bioservo Technologies, a Swedish medical tech company, so that it can finally be used to help workers here on Earth. Bioservo will fuse the RoboGlove technology with its own Soft Extra Muscle (SEM) Glove technology in order to make gloves for industrial use, according a press release from GM. “Combining the best of three worlds—space technology from NASA, engineering from GM and medtech from Bioservo—in a new industrial glove could lead to industrial scale use of the technology,” comments Tomas Ward, CEO of Bioservo Technologies.

Factory workers are about to get super-human strength. The glove helped scientists control Robonaut 2, a humanoid that provided engineering and technical assistance on space mission just like Star Wars’ R2-D2. But now it has been given power-boosting technologies.
Being a combination of sensors that function like human nerves, muscles and tendons the new Power Glove has the same dexterity of the human hand – but with mammoth strength. The ground-breaking muscle-mimicking technologies could help employees in health care. The glove could slash the amount of force an assembly operator needs to hold a tool during an operation in half.

Electric Car: Nanofiber Electrodes Boost Fuel Cells By 30 Percent

At the same time Honda and Toyota are introducing fuel cell cars to the U.S. market, a team of researchers from Vanderbilt University, Nissan North America and Georgia Institute of Technology have teamed up to create a new technology designed to give fuel cells more oomph. The project is part of a $13 million Department of Energy program to advance fuel cell performance and durability and hydrogen storage technologies announced last month.

hydrogen fuel cells

Fuel cells were invented back in 1839 but their first real world application wasn’t until the 1960’s when NASA used them to power the Apollo spacecraft. Fuel cells need fuel and air to run, like a gasoline engine, but they produce electricity, like a battery. In hydrogen/air fuel cells, hydrogen flows into one side of the device. Air is pumped into the other side. At the anode, the hydrogen is oxidized into protons. The protons flow to the cathode where the air is channeled, reducing the oxygen to form water. Special catalysts in the anode and cathode allow these reactions to occur spontaneously, producing electricity in the process. Fuel cells convert fuel to electricity with efficiencies ranging from 40 percent to 60 percent. They have no moving parts so they are very quiet. With the only waste product being water, they are environmentally friendly.The $2.5 million collaboration is based on a new nanofiber mat technology developed by Peter Pintauro, Professor of Chemical Engineering at Vanderbilt, that replaces the conventional electrodes used in fuel cells. The nanofiber electrodes boost the power output of fuel cells by 30 percent while being less expensive and more durable than conventional catalyst layers. The technology has been patented by Vanderbilt and licensed to Merck KGaA in Germany, which is working with major auto manufacturers in applying it to the next generation of automotive fuel cells.

Conventional fuel cells use thin sheets of catalyst particles mixed with a polymer binder for the electrodes. The catalyst is typically platinum on carbon powder. The Vanderbilt approach replaces these solid sheets with mats made from a tangle of polymer fibers that are each a fraction of the thickness of a human hair made by a process called electrospinning. Particles of catalyst are bonded to the fibers. The very small diameter of the fibers means that there is a larger surface area of catalyst available for hydrogen and oxygen gas reactions during fuel cell operation. The pores between fibers in the mat electrode also facilitate the removal of the waste water. The unique fiber electrode structure results in higher fuel cell power, with less expensive platinum.

Shower Of The Future Reduces Water Use Drastically

This shower is so futuristic, it could be from Mars. Its creators say the OrbSys recycled water shower could reduce water use by 90 percent, and save energy. But although its design was inspired by NASA‘s mission to the red planet, Orbital System‘s shower is for use on earth. CEO Mehrdad Mahdjoubi was inspired after a stint at the United States space agency. The shower works on a closed loop system – water falls from the showerhead to the drain where it’s purified to drinking water standard by a patented capsule. It’s then pumped back out of the showerhead.
shower2What began as a collaboration project between Lund University and NASA‘s Johnson Space Centre, Houston, made me question the possibility of recycling water on earth, like has been done in space. The shower of the future is a water-recycling shower, thus enabling water savings up to 90 percent, energy savings up to 80 percent, at the same time increasing comfort and hygiene.”

After the water is collected in the drain, analysed and the shower pump shoots it through our purification system, which consists of a micro-capsule that takes away the larger particles, then it goes to the nano-capsule, which takes away all of the smaller contaminants, making sure that the water that reaches the user from the recycling loop always is crystal clear and nice to shower in,” says Mehrdad Mahdjoubi.
The space-age technology means long showers won’t be a thing of the past, despite greater pressure on water resources.
What we are actually doing is we are changing the way that we humans relate to domestic water consumption. With the shower of the future…you can live a greener lifestyle without compromising on comfort,” he added. The shower has been tested at the Ribersborgs open-air baths in the south of Sweden. The company says it saved 100,000 litres of water over four months there. And after testing it all over Sweden. the OrbSys shower is ready for launch word-wide. Its developers say the purification technology could be used in taps and drinking fountains in developing countries, where water-related illness is rife.

Send Men Above Venus, NASA ‘s New Dream

To send an astronauts team around Venus is easier than to Mars. Why? Mainly because Venus is much closer to the Sun and due to continuous progress in the solar panel technology, any spaceship will benefit from an inexhaustible source of solar energy. The atmosphere of Venus is, as well, an exciting destination for both further scientific study and future human exploration. A lighter-than-air vehicle can carry either a host of instruments and probes, or a habitat and ascent vehicle for a crew of two astronauts to explore Venus for up to a month. The mission requires less time to complete than a crewed Mars mission, and the environment at 50 km is relatively benign, with similar pressure, density, gravity, and radiation protection to the surface of Earth. A recent internal NASA study of a High Altitude Venus Operational Concept (HAVOC) led to the development of an evolutionary program for the exploration of Venus, with focus on the mission architecture and vehicle concept for a 30 day crewed mission into Venus’s atmosphere.
NASA_HAVOCKey technical challenges for the mission include performing the aerocapture maneuvers at Venus and Earth, inserting and inflating the airship at Venus, and protecting the solar panels and structure from the sulfuric acid in the atmosphere. With advances in technology and further refinement of the concept, missions to the Venusian atmosphere can expand humanity’s future in space.

Cubesats, Super Powerful Tiny Satellites

A NASA engineer has achieved a milestone in his quest to advance an emerging super-black nanotechnology that promises to make spacecraft instruments more sensitive without enlarging their size.
A team led by John Hagopian, an optics engineer at NASA’s Goddard Space Flight Center in Greenbelt, Md., has demonstrated that it can grow a uniform layer of carbon nanotubes through the use of another emerging technology called atomic layer deposition or ALD. The marriage of the two technologies now means that NASA can grow nanotubes on three-dimensional components, such as complex baffles and tubes commonly used in optical instruments.

The significance of this is that we have new tools that can make NASA instruments more sensitive without making our telescopes bigger and bigger,” Hagopian said. “This demonstrates the power of nanoscale technology, which is particularly applicable to a new class of less-expensive tiny satellites called Cubesats that NASA is developing to reduce the cost of space missions.
