Amazing solar-powered fridge invented by British student in a potting shed helps poverty-stricken Africans

By Chris Brooke
It's the kind of simple yet brilliant invention that would have the tycoons of Dragons' Den salivating with excitement.
Not only is the fridge solar powered, it can also be built from household materials  -  making it ideal for the Third World.
Emily Cummins, 21, came up with the idea while working on a school project in her grandfather's potting shed. The fridge is now improving the lives of thousands of poverty-stricken Africans.

Blocklets!

Uma Ideia à parte, merece um Post à parte...
Via Ponoko:


About this project

Blocklets are a system of interlocking building blocks that can be used to make anything, from sculpture to furniture, and soon Arduino-based robots. Made of laser-cut wood and acrylic, they snap together with a satisfying 'click' and they feel great in your hand. 
The goal of this project is to not only set up a production facility to make Blocklets, but to also build a community to use and develop Blocklets. And here's the best part.  When we reach our funding goal, we will release the designs for Blocklets under a Creative Commons license. We can't wait to see the amazing things you can make with Blocklets, and the amazing ways you can modify, remix and repurpose and redesign Blocklets. We want your help to expand the capabilities of the Blocklets system with wheels, gears, hinges, shafts and many other components. We've got some great ideas in store, including an Arduino-based robotics kit, lamp kits, word art kits and more, but we need your support now to get started. Support us today to bring Blocklets to the masses.

Best Sun Images From Solar Space Telescope’s First Year

By Lisa Grossman 

NASA's Solar Dynamics Observatory, a space telescope charged with watching the sun in unprecedented detail, revealed its first look at the sun to the world one year ago today.
Since then, the telescope has watched the sun shift from its quietest period in years to the beginning of a new, active solar cycle. It's seen loops of plasma that dwarf the Earth tracing the sun's magnetic field, early stages of massive explosions that send hot charged material ripping through space, and sunspots dancing across the solar surface

New Graphene Material is Paper-Thin and Ten Times Stronger Than Steel
By Clay Dillow

Researchers at the University of Technology Sydney have created a new material that is lighter, less dense, harder, and stronger than steel. But this material isn’t one of those breakthroughs that only sounds good on paper. It is paper, and it could be a game-changer for materials science if it can live up to researchers’ hopes.

This graphene paper is constructed of graphite reformed by chemical processes into monolayer hexagonal carbon lattices stacked as thin as a sheet of paper, and it is remarkably strong. To quote a press release from UTS:

Compared to steel, the prepared GP is six times lighter, five to six times lower density, two times harder with 10 times higher tensile strength and 13 times higher bending rigidity.

That’s no incremental improvement on the qualities of steel, but a huge leap forward in terms of overall material strength (plus, like paper, it is flexible). And because it is graphene, it is also imbued with some interesting electrical, thermal, and mechanical properties.

The EUR65,000 Cavalon side-by-side, fully-enclosed gyrocopter

By Mike Hanlon


The newest addition to the gyrocopter genre arrived at Aero Friedrichshafen this week in the form of a side-by-side, fully-enclosed, composite construction Cavalon gyrocopter. The gyrocopter is to the helicopter what the microlight is to traditional small aircraft. Invented in 1923 by Spaniard Juan de la Cierva, the gyrocopter uses quite a different layout to the helicopter to give it stability at low speed. It is cheap to run, takes off and lands on a ridiculously small footprint, and has a powered pusher propeller in addition to an unpowered main rotor.

Researchers Succeed in Quantum Teleportation of Light Waves
By Rebecca Boyle

In a real-life use of Schrödinger's theoretical paradoxical cat, researchers report that they were able to quickly transfer a complex set of quantum information while preserving its integrity. The information, in the form of light, was manipulated in such a way that it existed in two states at the same time, and it was destroyed in one spot and recreated in another. The new breakthrough is a major step toward building safe, effective quantum computers.
No felines were harmed in the making of this experiment, which actually studied wave packets of light that existed in a state of quantum superposition, meaning they existed in two different phases simultaneously. This phenomenon is described in Erwin Schrodinger’s quantum mechanics thought experiment, in which a cat is simultaneously dead and alive, depending on the state of a subatomic particle.

Discovery paves way for “optical battery” to generate solar power without solar cells

By Darren Quick

It has long been thought that, even though light has electric and magnetic components, the effects of the magnetic field are so weak that they could effectively be ignored. Now researchers at the University of Michigan (U-M) have discovered that under the right conditions, a light field can generate magnetic effects that are 100 million times stronger than previously expected. The researchers say the discovery paves the way for the creation of an "optical battery" that could harness power from the sun without the use of solar cells.
Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics, and his colleagues found that if light focused to an intensity of 10 million watts per square centimeter (W/cm2) is traveling through a material that does not conduct electricity, such as glass, the light field can generate magnetic effects with the strength equivalent to a strong electric effect.

New coatings could protect jet engines from volcanic ash

By Ben Coxworth

Following last April's historic eruption of the Eyjafjallajökull volcano in Iceland, commercial flights were cancelled within most of Europe for several days – it was the largest disruption of air travel since the Second World War. Well, while no one is suggesting that airliners could now merrily fly right through clouds of ash, researchers from Ohio State University (OSU) have developed a coating that they say could allow jet engines to better withstand small amounts of volcanic ash that are ingested over time.
The metallic parts of jet engines are already coated with a ceramic thermal barrier coating, that allows them to withstand the 2500F (1371C) temperatures that occur during regular operations. When volcanic ash is sucked into an engine, however, it melts onto the coating and penetrates it. That ash becomes a brittle glass upon cooling and it flakes off, taking the coating with it.





E um Plástico barato de produzir avisa da deterioração dos alimentos...

Inexpensive plastic developed that indicates freshness of food

By Ben Coxworth
When it comes to buying packaged meat and fish, consumers usually just have to go by the "best before" label to know that it hasn't begun to spoil. Needless to say, the dates on those labels are just estimates and certainly won't tell you if the product has sat through a lengthy power failure, or been left out of the cooler for several hours. Researchers from the Fraunhofer Research Institution for Modular Solid State Technologies in Munich, however, have developed an inexpensive plastic film that will change color in the presence of rotten foods.
The film would be applied to the inside of food packaging, where it would respond to the biogenic amines produced by decaying meat or fish. If a sufficient amount of amines were present in the air within the sealed packaging, they would cause dye in the film to turn from yellow to an obvious blue.

Private Rocket Firm Under Pressure to Fill Space Shuttle Void
by Denise Chow

COLORADO SPRINGS, Colo. – Private rocket builder SpaceX is trying to speed up testing of its new Dragon spaceship to enable it to visit the International Space Station on the next demonstration flight.
With NASA's space shuttle programset to retire later this year, the pressure is on for commercial providers to compensate for the loss of the shuttles' enormous cargo-carrying capability.
"We have a very serious responsibility here because the space shuttle is coming to a close," SpaceX founder and chief executive Elon Musk told reporters here at the 27th National Space Symposium Tuesday (April 12). "What we've been told by NASA is that if we don't reach the space station by the end of this year, there's a risk that they will have to de-man the space station next year. We've got to be sure that we get to the space station. That is very much our primary focus." [Photos: SpaceX's Falcon 9 Rocket]

Isto promete, dos meus amigos Neo-Zelandeses da Diatom Studio, criaram uma nova library para o programa Processing, um programa grátis para Windows, Mac e Linux, que permite, com essa Library, não só fazer objectos, como desenvolver novas maneiras de os criar(?)

Via o Facebook da Ponoko:
Diatom Studio, the folks responsible for the SketchChair project that’s been mentioned here before, have created a neat library for Processing called CodeThread. It can be used not just for making objects, but for developing new styles of printing. As Diatom says on the CodeThread page on Thingiverse:
“One of the things we love about makerbot in contrast to commercial printers is that you have complete control over every aspect of the print technique. We think there is a lot of opportunity to develop new printing styles with makerbots, beyond traditional solid prints.
We wanted to experiment with the materiality of makerbot prints by working directly in gcode with processing, so we made this small library that provides some simple functions for generating gcode commands, and prints a gcode file.”

Quem se lembrar do Blitz Basic, bem, isto é MUITO MELHOR!
Para carregar e correr Processing no Ubuntu Linux, é só:
-Fazer o Download da versão Linux, 
-Descomprimir para a pasta, 
-E depois de entrar nessa pasta, botão direito em processing, Propriedades, Permissões, fazer correr como programa.
-A seguir, é só ir ao terminal, fazer sudo su, entrar na pasta, e escrever "sh processing"

Spider-silk-producing silkworms to be commercially developed

By Ben Coxworth

Although cobwebs may seem very fragile when we see people like Indiana Jones crashing through them, the fact is that spider silk is an incredibly strong and flexible material. It has a tensile strength similar to that of high-grade steel while only being one-fifth as dense, it can stretch up to 1.4 times its relaxed length without breaking, and it can maintain those properties down to a temperature of -40C (-40F). Given that spiders don't secrete huge quantities of the stuff on a daily basis, however, what's a biotech firm to do if it wishes to harvest the fibers for use in human technology? In the case of Sigma Life Science, it's getting genetically-modified silkworms to spin spider silk.

Cleaner-burning cook stove designed for use in developing nations

By Ben Coxworth

Chances are that even if you own a propane camp stove, you've tried cooking over an open fire at least once. When you did, despite your best efforts, you probably ended up sucking down a lot of smoke in the process. Now, imagine doing that for every meal. For many women in the developing world, breathing in toxic smoke while cooking over a wood, kerosene or coal fire is part of their daily routine. Not only can it have a detrimental effect on their own health, but it also worsens local air pollution and (in the case of wood fires) deforestation. The Eco Fire Pot Stove, however, is designed to allow these women to cook while breathing clean air.
The device was invented by Adama Kamara, a natural therapist who was born in Sierra Leone, but moved to Australia in 1996.

Radical-looking RoundTail bike claims radically smoother ride

By Ben Coxworth

If you banged a pole and a hoop against the road, which one would transmit more vibrations to your hand? Given that the flexing action of the hoop would absorb some of the energy, it's probably safe to assume that the pole would give you a numb hand quicker. Well, Canadian cyclist Lou Tortola applied the same sort of logic to the frame design of his Tortola RoundTail road bicycle. Where most other bikes would have a rear triangle consisting of straight seat stays, chain stays and a seat tube, the RoundTail simply has two shock-absorbing joined rings.

Earth Has an Orbital Companion Stuck in a Horseshoe-Shaped Orbit Around the Sun
Largest horseshoe companion known
By Clay Dillow


Near-Earth asteroids aren’t all that rare, but today two researchers at Armagh Observatory in Northern Ireland say they’ve found an extremely rare near-Earth object in an orbit very similar to Earth’s. Asteroid 2010 SO16 is not exotic because of it’s closeness to the home planet, but because it is stuck in a rare horseshoe orbit.

Horseshoe orbits only happen under a specific set of circumstances, so it is believed they are pretty rare. The name “horseshoe” is derived from the shape of the object’s orbit as seen from Earth--that is, it doesn’t stop mid-orbit, turn around, and travel in the other direction. It has everything to do with shifts in the object’s orbital path and our perspective of the object as it gets closer, shifts orbit, and then gets further away without ever passing Earth.

New advanced composite material lends itself to aircraft safety

By Frank Leonard

A combination of light weight AND strength makes advanced composite materials very useful when building something that's designed to go fast while being subjected to physical stress ... like an aircraft. On the downside, bulky equipment is required when it comes to inspecting these aircraft for damage – a problem that is MIT researchers hope to solve with the development of a new type of composite material that incorporates carbon nanotubes.
Aircraft composites consist of high-strength fibers, such as carbon or glass, embedded in a plastic or metal matrix. Unlike aluminum, they are not a uniform surface which means they can look fine on the outside despite being damaged internally – there's no noticeable crack or dent, so it's difficult to tell if there is damage?

Three Inventors Who Tried to Bottle the Ocean’s Power 
By Alexis Madrigal

A young man with artistic aspirations could not have resisted the crowds of Market Street on a Saturday night. Nothing was more San Francisco than the street that cut through its heart. Like a weekly fair, all classes of society and the many flags of a port town mixed on the promenade from Powell to Kearny. “Everybody, anybody, left home and shop, hotel, restaurant, and beer garden to empty into Market Street in a river of color,” wrote one young woman of the time.
Among the throngs of sailors and servants, we could almost certainly have found a young Jewish kid with an overbearing father and a canted, humane take on human foibles. Long after the 1890s and far away from the city by the bay, he would make a name for himself with a set of drawings that made him the most popular cartoonist of the machine age.

Video: Elektra One All-Electric Plane Makes Successful Maiden Flight
By Clay Dillow

German company PC-Aero is trying to win NASA’s CAFE Green Flight Challenge, and Saturday they took a big step toward doing just that. The company’s Elektra One aircraft, designed by PC-Aero’s founder and president Calin Gologan, made its successful first flight. But this one-seater isn’t your average single-prop. Elektra One flies on electricity alone.
The Green Flight Challenge seeks a demo aircraft that can fly 200 miles in less than two hours on the energy equivalent of less than one gallon of fuel per person. Elektra One didn’t push the envelope that far just yet--the maiden flight hit a ceiling just above 1600 feet and lasted just 30 minutes, burning just half the 6 kWh stored up in its batteries. But the fact that the lightweight aircraft was able to comfortably circle the airfield for half an hour-- more or less silently, we might add--is nothing short of impressive.
