Personally, I'm getting a little sick of the 3D trend that is visible everywhere. I mean, 3D printers, movies, and game consoles, it's all starting to become a bit ridiculous. Finally, there's a piece of 3D that I can get behind. Researchers at Massachusetts Institute of Technology have recently discovered that a 3D inspired solar panel could produce 20 times more energy than its traditional flat brethren.
Traditional solar panels lay on a roof facing the sun to produce energy. MIT researchers decided to test the hypothesis set forth by 13-year-old Adiean Dywer. He hypothesized that a design based on trees would produce more energy. His testing failed, but MIT's didn't. MIT tried various 3D shapes such as a cube, tall cube, and tower to see which produced the most energy. All three outpaced the traditional panel and the accordion-style tower drew in 20 times more power per square foot.
"I think this concept could become an important part of the future of photovoltaics," said Jeffrey Grossman, one of the project leaders. The accordion-style worked so well because it could absorb energy from all angles. It also reduces the foot print of the installation by standing vertically. While MIT is confident with the tower design, they haven't figured out the best distribution for them yet. Since one tower may shade another, they are best used in a urban environment...at least for now.
Harry Potter's invisibility cloak is pretty cool. But it's just fantasy, isn't it? Well, by applying some technology, scientists have been able to make a breakthrough in cloaking objects from heat-sensing cameras and the like. This is done by controlling the flow of heat, either focusing it into a small point, or spreading it outside of an invisibility zone.
the technology will most likely go to the military, where something similar has been proven to hide a tank. This technology also has applications in computers, because it is fundamentally shuffling heat around at will. In computers, heat is still a major challenge for engineers. "We can design a cloak so that heat diffuses around an invisibility region, which is then protected from heat," Dr Guenneau explained. "Or we can force heat to concentrate in a small volume, which will then heat up very rapidly."
It could also be used by thieves, provided they can steal it from the military in the first place. They would be able to hide from police helicopters at night, or from thermal imaging alarm systems. Harry Potter's cloak is becoming reality. It will just take more time and research.
OK, I'll admit it: I'm scared of heights. I live in a two-storey house and can barely look over my balcony without feeling scared. But this, this is just absolutely insane! Enter "Fearless Felix" Baumgartner, who has jumped 2,500 times from planes, and helicopters as well as some of the world's highest landmarks and skyscrapers, such as the Christ the Redeemer statue overlooking Rio de Janeiro, the Millau Viaduct in southern France, and the 101-story Taipei 101 tower in Taiwan.
This summer, Baumgartner hopes to fly toward the Earth at supersonic speeds from a record 23 miles above the Earth, breaking the sound barrier... with only his body. During a dress rehearsal last Thursday, he made it more than half-way, ascending from the New Mexico desert in a helium balloon, and jumping from more than 13 miles up. It's said that he is one of only three people who have jumped from such a height and free-fall to a safe landing. He's also the first to do so in 50 years.
He's even caught the attention of NASA, where engineers working on astronaut escape systems for future spacecraft keeping an eye on the skydiver. Here's where things get insane: Baumgartner took a 100-foot helium balloon and pressurized capsule which lifted from Roswell, New Mexico last Thursday morning. He then jumped at 71,581 feet - 13.6 miles - and landed safely just 8 minutes and 8 seconds later.
Check out this cool use of an Arduino. It's a robotic arm that writes the time, erases it, and then writes up the new time over and over again. This device gives a whole new meaning to the phrase "time stops for no man." Apparently, "time stops for no man or machine." The robotic arm was created by a hacker going by the name of Ekaggrat. Of course, I'm sure you'd like to see this in action, so take a look at the video below.
I'm not sure just how practical something like this is to replace current clocks, but it sure is cool! What a display to have in a maker-shop or robotics office. Now, if only he provided instructions and the code required so that we could all make them in our own homes!
A few months ago, news found its way into the world that scientists in the Geneva-based CERN lab had broken the speed of light. But, news has broken that this may have been a 'connection' problem. The news is from a source close to the experiment, who spoke to the US journal, Space Insider that "a bad connection between a GPS unit and a computer may be to blame".
Scientists had originally claimed that neutrinos arrived 60 nanoseconds earlier than the 2.3 milliseconds taken by light. Science Insider reported:
The 60 nanoseconds discrepancy appears to come from a bad connection between a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos' flight and an electronic card in a computer. After tightening the connection and then measuring the time it takes data to travel the length of the fiber, researchers found that the data arrive 60 nanoseconds earlier than assumed.
Since this time is subtracted from the overall time of flight, it appears to explain the early arrival of the neutrinos. New data, however, will be needed to confirm this hypothesis.
3D printers have come a long way now, and in 2012, they're ready to do something quite miraculous. An 83-year-old woman is set to be the first to receive a titanium jaw crafted by one of these 3D printers.
The method was developed by the BIOMED Research Institute at Hasselt University in Belgium and what the printer does is create the low jaw replacement from layer-upon-layer of titanium dust. This is made possible by using a computer-controller laser that ensures the correct molecules are fused together.
The result, is a perfect titanium jaw which takes just hours to built, versus previous options where it would take days. Of course this new nail-biter weighs a bit more than its natural bone-based predecessor, but that doesn't stop the patient from returning close to "normal speaking and swallowing" the day after the operation.
First off, some back story. This will end up as a mini-editorial, but some of you will find this very interesting. Lake Vostok is a large (10,000km2), presumably fresh water body located under some 4km of ice in East Antarctica. The lake is not some little pool of water, its a gigantic, 250km long and 50km wide.
Because the lake is under kilometres of frozen ice, it has been untouched by todays technology and hence, the hands of man. The contents of this secret under-the-ice lake, have not seen the light of day for more than 20 million years. Because of this long period of pure isolation, it is believed that the water inside Lake Vostok could contain new, never-before-seen lifeforms, and unique geochemical processes.
For the past five-plus years, Russia and the United States have been seeking to probe Vostok in order to discover its underlying secrets from this pure, pristine body of water. The problem associated with such an untouched body of water is that as soon as it is discovered, tested and exposed, we would have contaminated it in multiple ways. Because of its long period of isolation, it cannot be explored without the introduction of the outside world, i.e. us.
We're not even finished with the first month of 2012 and we are already experiencing some seriously powerful stuff happening to us because of one of the most important things we, humans, require to live: our Sun, our Star. The Sun, at around 0359 UT on January 23, from sunspot 1402 erupted and produced a long-duration M9-class solar flare.
The explosion's M9-ranking puts it on the threshold of being classed an X-flare, the most powerful there can be. NASA's Solar Dynamics Observatory captured the flare's most extreme ultraviolet flare, below:
The resulting coronal mass ejection (CME) hit Earth's magnetic field at 0617 UT on January 22 and according to analysts at the Goddard Space Weather Lab, the CME strongly compressed Earth's magnetic field and briefly exposed satellites in geosynchronous orbit to solar wind plasma. The effects of this will last roughly 24 hours, where Earth's magnetic field reverberates from the impact. This causes bright auroras to be seen around the arctic circle. Bjørn Jørgensen observed this display from Tromsø, Norway:
Jørgensen said "this was amazing, it was a wonderful experience to see these stunning auroras".
Is it a bird? Is it a plane? No, it's Microsoft co-founder Paul Allen who has plans to create a business for commercial space travel
Space Travel. Microsoft. Skynet. The steps are there, and we're hitting them at a nice pace. Microsoft co-founder Paul Allen has announced new plans to create a business for commercial space travel. It should take roughly five years to develop.
With the U.S. government slicing space flight, Allen has sensed a gap in the market for investment. Yesterday, Allen showcased designs for a new craft that would eventually have the ability of taking human passengers into the vast space that is, well, space.
Allen has previously funded spaceflight, as he was behind SpaceShipOne, which was the first manned private journey. Stratolaunch System are the ones behind the building of the new craft, which is a company founded by Paul Allen.
Lunar Eclipse this Saturday, visible in Australia and parts of Asia, won't be seen against until 2014
Want to see something you won't be able to see again for another three years? Well, be outside on Saturday and you'll see a lunar eclipse. It will only be visible from Australia and in some parts of Asia.
The entire moon will turn red, as it falls behind Earth's darkest shadow. Sydney Observatory's Geoffrey Wyatt says:
People will see the shadow of the earth moving across the moon, and for 52 minutes witness the usually milky white moon turn a blood-red rusty colour.
This is the second total lunar eclipse this year, with the previous one in May. Wyatt says that the east coast will be the one of the best places on Earth to see the eclipse. It is set to start at around 11:30pm on Saturday, and last for around three hours.
Thank you to my wife for reminding me of this news!
