PumpTire: Self Inflating Bicycle Tire

PumpTire: Tire Inflates Itself As You Ride - Technabob
http://technabob.com/blog/2011/08/29/pumptire-self-inflating-bike-tire

  • The PumpTire is a revolutionary design by Benjamin Krempel that’s currently up for funding on Kickstarter. The tire actually employs a mechanism that pumps your bike tires as you pedal and move along, ensuring that you will never have a flat tire or ever have to manually pump some air into your tires – if all goes well, that is.
  • The PumpTire is fitted with a valve and a special inner tube that work hand-in-hand to determine if your tires are full or if they could still use a pump or two of air. As you can see from the video clip, Krempel already has a working prototype of the PumpTire, and just needs funds to ramp up production.

  • The PumpTire features a special valve which, like a conventional valve, can attach to a bicycle pump for manual inflation but also takes in air as the tire spins. The air is channeled into a small tube, or "lumen," that runs around the outside of the tire, where it makes contact with the ground. The weight of the bike squeezes the air out of the lumen and into the inner tube. The specially designed valve automatically shuts off and stops its air intake when the desired tire pressure is reached.

  • To make his two types of tires -- the City Cruiser for the casual,  urban cyclist and the City Pro High Performance Tire for professional riders -- Krempel needs a hefty cash injection. He's asking for $250,000 on Kickstarter, and has raised $12,000 so far, with a month or so to go.
    If his funding drive is successful, Krempel and his company will sell the Cruiser wheel set for $64.95 (£50 with international shipping) and the Pro kit for $129.90 (about £100 with postage to Britain).

  • Russia has unveiled an ambitious plan to build the world’s longest tunnel under the Bering Strait as part of a transport corridor linking Europe and America via Siberia and Alaska.

     The 64-mile (103km) tunnel would connect the far east of Russia with Alaska, opening up the prospect of the ultimate rail trip across three quarters of the globe from London to New York. The link would be twice as long as the Channel Tunnel connecting Britain and France.

     The $65 billion (£33 billion) mega-project aims to transform trade links between Russia and its former Cold War enemies across some of the world’s most desolate terrain. It would create a high-speed railway line, energy links and a fibreoptic cable network.

  • The high speed railway and tunnel will be a private public partnership whose economic impact could be startling. 100 million tons of freight could be moved per year using the most efficient known way of transport. Proposed tidal energy plants could provide 10 gigawatts of energy and a string of wind power fields could churn a constant supply of clean energy, serving as a vital link to a worldwide energy grid. The tunnel alone would take fifteen years to complete — and an energy and railway network would take many more — but the project would significantly change the shipping and energy industry.

    • Computerization has had a major impact on just about every aspect of manufacturing and fabrication. It’s also led to a democratization of the process, enabling enthusiastic DIYers with a bit of know-how (and a little extra cash in their bank accounts) to create some pretty amazing things with devices like 3D printers, desktop laser cutters, and programmable CNC machines.
    • It’s this last piece of equipment that WikiHouse wants to help you put to good use. The goal of WikiHouse is to allow people to freely download “open source structures” which can be opened and modified using Google Sketchup. The plans’ building components are designed to be milled from 18MM sheets of plywood, and the resulting pieces can be fitted together like a giant puzzle. They’re even labeled during fabrication, making it perhaps a bit more like building an Ikea desk (though that can be puzzling at times). In addition to marking pieces for easy assembly, the CNC will even cut a wooden mallet that can be used to ensure a tight fight between panels.

    Digital Holographic Microscopy (DHM) Reveals Brain's Inner Workings

    Holograms reveal brain's inner workings | Health | EarthSky
    http://earthsky.org/health/holograms-reveal-brains-inner-workings


    • Scientists have discovered a way to observe living neurons without damaging them – in 3D and with up to 50 times greater resolution than before. The technique, using digital holographic microscopy (DHM), is non-invasive and can create imagery of hundreds of neurons at once. DHM has the potential to streamline drug studies involving neurodegenerative diseases such as Parkinson’s and Alzheimer’s, because researchers can test new drugs more quickly and in greater numbers than before.

       The research team, from Switzerland’s École Polytechnique Fédérale de Lausanne (EPLF) and Centre Hospitalier Universitaire Vaudois (CHUV), included neurobiologists, psychiatrists, and advanced imaging specialists. Results of their collaboration appear in the August 17, 2011 issue of The Journal of Neuroscience.

    • “DHM is a fundamentally novel application for studying neurons with a slew of advantages over traditional microscopes,” explains Pierre Magistretti of EPFL’s Brain Mind Institute and a lead author of the paper. “It is non-invasive, allowing for extended observation of neural processes without the need for electrodes or dyes that damage cells.”

       Senior team member Pierre Marquet adds, “DHM gives precious information not only about the shape of neurons, but also about their dynamics and activity, and the technique creates 3D navigable images and increases the precision from 500 nanometers in traditional microscopes to a scale of 10 nanometers.”

      Typical optical setup of DHM.

    • Digital holographic microscopy (DHM) is digital holography applied to microscopy. Digital holographic microscopy distinguishes itself from other microscopy methods by not recording the projected image of the object. Instead, the light wave front information originating from the object is digitally recorded as a hologram, from which a computer calculates the object image by using a numerical reconstruction algorithm. The image forming lens in traditional microscopy is thus replaced by a computer algorithm.

    • Real-time monitoring
      The DHM system is an ideal tool for real-time cell monitoring because it allows, from a single image acquisition, non-invasive high-resolution imaging of living cells in their natural environment without use of a contrast agent. The real-time imaging (up to 15 fps for a 512x512 pixels image) and the postponed reconstruction (up to 10'000 fps by using high-acquisition rate camera) make the DHM instrument a system well suited for the dynamic analysis of morphological modification of cells due to natural or artificial stimulations such as drugs, electrical or thermal stimuli.
      For example, neuron cell swelling induced by hypotonic stress was studied by the Brain Mind Institute (EPFL, Switzerland).

    Living Bridges

    • In the depths of northeastern India, in one of the wettest places on earth, bridges aren't built—they're grown.
    • The root bridges, some of which are over a hundred feet long, take ten to fifteen years to become fully functional, but they're extraordinarily strong—strong enough that some of them can support the weight of fifty or more people at a time. In fact, because they are alive and still growing, the bridges actually gain strength over time—and some of the ancient root bridges used daily by the people of the villages around Cherrapunji may be well over 500 years old.
    cherrapunjee.com
    http://www.cherrapunjee.com/index.php?mid=66&pid=66
    • The lower reaches of the southern slopes of Khasi and Jaintia hills are humid and warm and are streaked by many swift flowing rivers and mountain streams.  A species of Indian Rubber tree - botanical name: Ficus elastica - thrives and flourishes alongside these streams and rivers. 
    •  Our ancestors, the early war-Khasis, had noticed these qualities of this tree and had adapted it to serve their need for bridges to cross rivers and streams.  In order to direct the roots in the desired direction, betel nut tree trunks, sliced half in the middle for their entire length, are hollowed out and are positioned according to the requirement of the bridge.
    • Cherrapunjee Holiday Resort has brought the focus on these Living Root Bridges, which are exclusive only to Meghalaya and are not found anywhere else in the world.

    Redirecting Asteroid Apophis From its Collision Course with Earth

    Apophis 99942: The Killer Asteroid of 2036 - YouTube
    http://www.youtube.com/watch?v=zazuzkO9nNk

     
    This is a short clip of scenes which depict scenarios of the happenings that might take place on April 13, 2036. The asteroid will come very close to the Earth in 2029, but miss. That close encounter will trigger a collision in 2036
    Asteroid Apophis 2036 The Official Asteroid Apophis site. Near Earth Asteroid and news.
    http://asteroidapophis.com
    • Asteroid Apophis is a possible Earth bound asteroid. Known as 99942 Apophis is a near-Earth asteroid that had caused concern in December 2004 because initial observations indicated a small probability (up to 2.7%) that it would strike the Earth in 2029. Recent news indicate that it could be on a collision course afterall.
    • Apophis will come within 18,000 miles from earth on Friday, April 13th, 2036. That amount of miles is actually very, very close and it will be visible to the naked eye. You thought Halley’s comet was the talk of the world in the 1980’s…just wait until this Asteroid Apophis comes knocking on our door.

       Asteroid Apophis is 1,000 feet in diameter, which is about 90 stories tall and weighs 25 million tons. If this asteroid hits anywhere on earth it would be 68,000 times the force that the atomic bomb that destroyed Hiroshima.

       NASA labeled Apophis as a Near Earth Object. Lets just hope it stays in that label and not become an impact asteroid.

    http://www.theblaze.com/stories/1600-foot-wide-asteroid-headed-for-earth-in-2036-can-scientists-stop-it
    • The European Space Agency will test its technique against a real asteroid in 2015 in a mission called Don Quijote. Don Quijote involves two spacecrafts. One, called Hidalgo, will impact the asteroid at a speed of six miles per second while the other (Sancho) will orbit the asteroid before and after collision collecting data and analyzing just how far off course the impactor spacecraft threw the asteroid.

      Watch the European Space Agency’s simulation here:

    • Similarly, the Chinese researchers propose hitting the asteroid with a spacecraft, but the method of getting there is a bit different. They propose using a solar sail (a form of spacecraft propulsion) to send the spacecraft into retrograde orbit and on a collision course with the asteroid.


    • Shengping Gong and pals at Tsinghua University in Beijing say they've come up with a plan that will ensure Apophis never returns to Earth on this timescale .

       They point out that keyholes are tiny, in this case just 600 metres wide. So deflecting Apophis by only a small amount in the near future will ensure it misses the keyhole and so cannot return to Earth.

       There are various ways to deflect an asteroid. Gong and pals say their preference is to use a solar sail to place a small spacecraft into a retrograde orbit and on collision course with Apophis. The retrograde orbit will give it an impact velocity of 90km/s which, if they do this well enough in advance, should lead to a collision large enough to do the trick.

       Putting a spacecraft into a retrograde orbit about the Sun using little or no fuel is a pretty neat trick by anyone's standards.. The Chinese team's calculations demonstrate the point. They show that a 10 kg sail in retrograde orbit, that hits Apophis a year before 2029, would deflect it enough to miss the keyhole, thereby eliminating the chance that the asteroid will return in 2036.

    MABEL The Fastest Human-Like Running Robot

    Running robot: MABEL is now the world's fastest two-legged robot with knees
    http://ns.umich.edu/htdocs/releases/story.php?id=8508
    • ANN ARBOR, Mich.—A robot in a University of Michigan lab can run like a human—a feat that represents the height of agility and efficiency for a two-legged machine. With a peak pace of 6.8 miles per hour, MABEL is believed to be the world's fastest bipedal robot with knees.

     Proud: The University of Michigan team with MABEL the running robot

    • Professor Jessy Grizzle, from the University of Michigan, where MABEL was built, also stressed how useful human-like robots could be.

       He said: ‘The robotics community has been trying to come up with machines that can go places where humans can go, so a human morphology is important.

      ‘If you would like to send in robots to search for people when a house is on fire, it probably needs to be able to go up and down stairs, step over the baby’s toys on the floor and manoeuvre in an environment where wheels and tracks may not be appropriate.’

      It’s taken the researchers three years to get MABEL up and running to her current top speed and she needs the aid of a stabilising boom, but she still represents a huge step forward for robot-kind.

      ‘It's stunning,’ Professor Grizzle adds. ‘I have never seen a machine doing a motion like this.’
    Grizzle, Jessy W.: Biped Experiments (MABEL)
    http://www.eecs.umich.edu/~grizzle/papers/MABEL.html
    • Research objectives: MABEL was designed to be both a robust walker and a fast runner. It pushes the state of the art in bipedal mechanism design and provides an opportunity for effective control design methodology to maximize the robot's energy efficiency, speed, and stability. Our specific objectives are to demonstrate: energy efficient walking on flat ground; the ability to walk over uneven terrain; and running. All of this should be accomplished with provably correct feedback laws. The emphasis on energy efficiency is because, for a biped to be able to operate in the real world for an extended period of time, it must carry its own power and use that power as economically as possible. The ability to walk on uneven ground will allow bipeds to function out of the laboratory. The ability to run is in part for fun and in part to demonstrate dynamic balance in an extremely challenging situation. The running achieved with current bipeds is very unsatisfactory. Just take a look at their gaits and you'll see what we mean. Finally, the emphasis on provably correct feedback laws is because we are attempting to remove a lot of the trial and error from the process of designing control algorithms for bipedal robots. Our objective is to design controllers on the basis of models and have the controllers work on the associated hardware. It's a big challenge! Maybe the biggest one in the list.
