Porque os "carros eléctricos" são, sinceramente, uma anedota, e iriam arruinar as já sobrecarregadas e sobre-reguladas Redes Eléctricas, eis algo de REALMENTE positivo, um Combustível Líquido, a partir de Energia Solar, sem ter de roubar Alimento às populações, como o Bio-Etanol...


Researchers generate liquid fuel using electricity

By Darren Quick

While electric vehicles have come a long way in the past decade, they still have many disadvantages when compared to internal combustion engine-driven vehicles. The lithium-ion batteries that power electric vehicles have a much lower energy storage density when compared to liquid fuel, they take longer to “refuel,” and they lack the supporting infrastructure that has built up around conventional vehicles over the past century. Now researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a process that could allow liquid fuel to be produced using solar generated electricity.
Using only electricity for the energy input, the team was able to convert carbon dioxide into the liquid fuel isobutanol. They did this by genetically engineering a lithoautotrophic microorganism (one that utilizes inorganic compounds as energy sources) known as Ralstonia eutropha H16 to produce 3-methyl-1-butanol and isobutanol, a colorless, flammable liquid that holds potential as an alternative to gasoline in combustion engines. The microorganism was placed in an electro-bioreactor and used only carbon dioxide as the carbon source and electricity as the sole energy input.





Eis algo de fantástico, um Novo Material que pode substituír o Aço, 30% mais leve, e é um Material fácilmente moldável:


Polyurethane composite could replace steel or aluminum in some applications

By Ben Coxworth

A consortium of German research groups has created a new sandwich-type material that they claim offers strength similar to that of steel or aluminum, yet is significantly lighter and less expensive. It consists of a honeycomb-structured paper core, with glass fiber-reinforced layers of polyurethane on the outsides. To give an idea of how tough it is, it’s about to be tested on the diesel engine housing of a train.
The material is intended for a number of applications, but it was decided that the engine housing would be a good test. The housing will be located on the underside of the train, where it will be constantly subjected to track debris such as flying rocks. It must also contain engine fluids such as oil, to keep them from leaking into the environment, while additionally serving to contain the flames in the event of an engine fire – additives in the polyurethane ensure that it meets fire safety standards.





...E esta pequena maravilha, com muitas aplicações, mas dá um Brinquedo do caraças...



Collapsible “Buckliball” turns failure into functionality

By David Szondy

Taking inspiration from a toy, a team of researchers at MIT have developed a new engineering structure that is mechanically unstable, yet collapses in a way that is predictable and reversible. The structure, formed out of a single piece of rubber-like material, is fabricated so that it collapses in harmony to form a smaller structure that can then be expanded into the original shape. This structure opens up new potentials in everything from architecture to micro-medical applications.

When we think of structures, we tend to think of them as things that don’t fall down. If you had to come up with one common criterion for bridges, buildings, houses, stadiums, sheds and dog houses, it’s that once built, they should tend to stay upright and not come crashing down around people’s ears. If they do so, that is generally regarded as a failure, so engineers put a great deal of effort into keeping that from happening.

Uma boa notícia, a Fibra de Carbono do amanhã poderá vir... Dos sacos de plástico!



Tomorrow's carbon fiber could be made from plastic bags

By Ben Coxworth

Thanks to research currently being conducted at the U.S. Department of Energy's Oak Ridge National Laboratory, our unwanted plastic bags may one day be recycled into carbon fiber. Not only that, but the properties of the fibers themselves could be fine-tuned, allowing different types of carbon fiber to be created for specific applications.

The Oak Ridge team, led by materials scientist Amit Naskar, start with polyethylene-base fibers – these could conceivably come from waste plastic sources, such as shopping bags and carpet backing scraps. Using a “a multi-component melt extrusion-based fiber spinning method,” the surface contours of these fibers can be customized, and their diameter can be manipulated with submicron precision. It is also possible to control their porosity.

Bundles of these fibers are dipped into a proprietary acid chemical bath. A process known as sulfonation causes the plastic molecules to bond with one another, transforming each bundle of fibers into one joined black fiber.

MIT researchers create camera that can see around corners

By Darren Quick

Fans of the classic 1982 science fiction movie Blade Runner will remember the ESPER machine that allows Deckard to zoom in and see around corners in a two-dimensional photograph. While such technology is still some way off, researchers in MIT’s Media Lab have developed a system using a femtosecond laser that can reproduce low-resolution 3D images of objects that lie outside a camera’s line of sight.
The experimental setup designed by the MIT researchers gained attention last December when video of it capturing a burst of light traveling through a plastic bottle was released. But as amazing as that capability is, it was for the even more amazing ability to literally see around corners that the team says the system was developed.

Seagate demonstrates HAMR hard drive technology that promises 60 TB HDDs

By Darren Quick

Despite solid state drives increasing in capacity in recent years, the humble platter-based 3.5-inch hard drive still reigns supreme as the data storage device to beat in terms of bits for your buck. But if traditional drives are going to meet user’s ever-increasing data storage demands they will need to improve on the maximum 620 gigabits per square inch storage densities currently possible in platter based 3.5-inch drives. That’s just what Seagate has demonstrated with new technology that has achieved a milestone storage density of 1 terabit per square inch.

From the advent of hard drives in 1956, the magnetic surface of the hard drive platters was divided in sub-micrometer-sized regions called magnetic domains that were oriented horizontally and parallel to the disk surface in what was called longitudinal recording. But around 2005/2006, Perpendicular Magnetic Recording (PMR) was introduced, which changed the orientation to perpendicular to allow for closer magnetic domain spacing and increase data storage capacity.

Futuristic biplane design eliminates sonic boom

By James Holloway

A throwback to early 20th Century aviation may hold the key to eliminating the sonic boom - at least according to researchers at MIT and Stanford University. Strongly reminiscent of biplanes still in use today, the researcher's concept supersonic aircraft introduces a second wing which it is claimed cancels the shockwaves generated by objects near or beyond the sound barrier.
In fact the idea is not a new one. The idea of a biplane to negate the sonic boom was proposed in the 1930s by aviation pioneer Adolf Busemann, also responsible for the idea of swept-wing aircraft.
Aircraft traveling at supersonic speeds cause shockwaves in the air around them. A first boom is caused by the rapid compression of air at the front of the plane, literally pushed together by the aircraft. A second is caused by the negative pressure left in the plane's wake - or rather, the rapid return to normal pressure that follows soon after. Though the two booms separate phenomena, they occur so close together that they they are usually perceived as a single sound. An aircraft in supersonic flight creates a continual boom as it goes.

Introducing the ShapeOko 3D printer/CNC kit!

The $300 open hardware CNC machine is here. And it’s also a 3D printer!

Last summer, Edward Ford announced a Kickstarter campaign to support a project he had been coming back to for years: the most affordable desktop CNC machine ever, completely open hardware.
Edward’s project was over 700% funded, and he immediately set out improving his initial design. He also set up ShapeOko.com, and blogged about his progress along the way.
It’s been 8 months of late-nights in the garage, community feedback, sourcing woes, and huge support. And a few weeks ago the first batch of ShapeOko kits shipped out to his Kickstarter supporters.
ShapeOko looks a lot different these days than the previous laser-cut MDF machine holding a ballpoint pen. : )

It now features extruded aluminum rails from MakerSlide, custom laser-cut steel plates, and an 8″x8″ cutting area with a Z axis height of 3.5″

Flat polymer sheets bend themselves into 3D shapes - just add water

By Ben Coxworth

When the petal of a flower is being formed, its shape is achieved by cells in one area expanding more than cells in an adjacent area. This uneven expansion causes the material to buckle, creating the desired curves and creases. Scientists from the University of Massachusetts, Amherst have taken that same principle, and applied it to flat polymer gel sheets that fold themselves into three-dimensional shapes when exposed to water. Some day, such sheets could serve a number of useful purposes.

The researchers use a photolithography process, in which parts of each sheet are masked with a thin painted-on coating, followed by an exposure to ultraviolet light. The polymer that is masked from the UV light will uniformly expand like a sponge when exposed to water. In areas that aren't masked, however, the UV light causes the molecules within the polymer to become cross-linked. This means that the material in those areas will only experience limited expansion when water is added.

Nanoscale 3D printing

Is this the smallest race car you’ve ever seen?

Researchers at the Vienna University of Technology have a bit of a penchant for speed. And it’s not just the nanoscale 3D printed race car that gives it away… the team there have developed a mirror guided, laser equipped 3D printer that is officially faster than any that has come before.
…printing speed used to be measured in millimetres per second – our device can do five metres in one second.
Not only is it fast, it is also remarkably accurate. The printed structures are highly detailed, yet no bigger than a grain of sand. These results are achieved using a process called two-photon lithography – developed through the combined might of specialised molecular chemists working together with mechanical engineers.

SAFFiR robot could be putting out fires on Navy ships

By Ben Coxworth

If there's one thing that you don't want happening on board a ship, it's a fire. People on board burning ships can't simply run out onto the streets, as they hopefully could in the case of a structural fire, plus many people caught belowdecks don't have windows nearby to climb out of. Then, there's also the fact that crew members fighting such fires have to work in narrow, claustrophobic passageways, instead of wide-open roads. Given that fires are particularly possible on military ships, due to attacks by enemy forces, America's Naval Research Laboratory is now developing a special something to help fight fires at sea - it's called SAFFiR, the Shipboard Autonomous Firefighting Robot.

SAFFiR will be an autonomous bipedal humanoid robot, based on the CHARLI-L1 robot created at Virginia Tech - the school is a partner in the project, as is the University of Pennsylvania.

Raspbery Pi, e um Site bacano

A loucura do Raspbery Pi já me atacou, é um projecto fascinante, um PC que corre Linux, por 25 Euros:


Raspberry Pi

About us

If you want to find out what the Raspberry Pi is, head to our FAQ page.
The idea behind a tiny and cheap computer for kids came in 2006, when Eben Upton and his colleagues at the University of Cambridge’s Computer Laboratory, including Rob Mullins, Jack Lang and Alan Mycroft, became concerned about the year-on-year decline in the numbers and skills levels of the A Level students applying to read Computer Science in each academic year. From a situation in the 1990s where most of the kids applying were coming to interview as experienced hobbyist programmers, the landscape in the 2000s was very different; a typical applicant might only have done a little web design.
E vejam só este Vídeo duma dessas placas, feito em Sketchup...
Isto dá-nos a ideia de fazer o mesmo tipo de vídeos, para tudo o que queiram ilustrar, Protótipos, ideias, etc:





Como é usual nestes casos, uma coisa leva a outra, e eis este Site bacano, com uma quantidade de Ficheiros 3D Sketchup de PCs feitos e modificados à vontade do freguês, que é como dizer, Case modding:


This site is a repository for SketchUp components (3D models) related to the design of custom-build PCs. (a.k.a. Case Modding)
There is a thriving community at the bit-tech.net forums (amongst others) which enjoys this increasingly popular hobby.

Make a 30tonne hydraulic press. Squash anything!


This instructable will show you how to make a 30tonne hydraulic press. In my press i use some serious hardware, and the final press is going to end up weighing 86kg, which is 164lbs or 13.5 stone. I use M42 threaded rod which is 42mm wide and weighs a tonne. There is nothing to stop you using smaller hardware, I am told that M30 rod (which you can buy from RS for 10 quid will take 26 tonnes, so two of those would handle it fine.

However you build it, its a nice project, and the finished product is great fun to use.

Melhor Design, mais barato... MakiBox!

Uma Impressora 3D que não abana como uma aranha maluca, é pequena, mas imprime um pequeno barrote, e é BARATA?
Isto promete...


MakiBox A6 aims to bring affordable 3D printing to the desktop

By Randolph Jonsson

Over the past few years, the price of desktop 3D printers has been falling thanks to devices such as the uPrint, MakerBot, Printrbot and Cubify ). But designer Jon Buford's thoughtfully-conceived MakiBox looks to be the least expensive yet. He and his team have now pre-sold enough of the device to make the move from prototype to market and the result looks rather promising. If all goes well, the US$300 printers (plus US$50 for global shipping) could be available for delivery as soon as the end of the month.

The 280 mm x 210 mm x 210 mm (11 x 8.27 x 8.27 in) self-contained MakiBox has a footprint about the size of a piece of standard letter paper, yet can build objects up to 150 mm x 110 mm x 110 mm (5.9 x 4.3 x 4.3 in) in size - about a quarter of the printer's overall volume. Replicator G, an open source 3D printing software application compatible with Windows, Mac and Linux, drives the printing process during which spooled 1 mm (0.04 in) diameter polylactide (PLA) plastic filament is melted and extruded in thin layers at 60-80 mm (2.36-3.15 in) per second.

The Pirates! 3D Printing Now Used for Animated Films

The Pirates! is the first animated film to embrace 3D printing on a large scale.
Characters of the new Sony Pictures movie have been partly created with 3D printing technologies. In order to make the Pirate Captain and his shipmates talk, artists of Aardman Animations 3D printed not less than 8000 mouths!
Key animator Ian Whitlock told Fox News that they build 257 separate mouths for the Pirate Captain and about 130 for the Charles Darwin model.
It was a real gain of time and allowed stronger animation styles to each face. Even if hand-molded plasticine is still used for most of the parts of the characters (the eyes for example), Aardman team was deeply impressed by the quality of 3D printing, mostly for creation and time purpose.

Vortex gun blows rings of high-speed electrified gas – could have numerous applications

By Ben Coxworth

While something called a "vortex gun" might sound like a device from science fiction, the fact is that they have been available as novelties for years - if you've ever used a toy gun that shot out a smoke ring, then you've used a vortex gun. Lately, however, scientists from the Ohio-based Battelle R & D group have developed one that could have practical uses for people such as firefighters, exterminators and riot cops.

Vortex guns work by forcing air or another gas at a high velocity, down the inside of a cylinder. Friction along the inside of that cylinder wall slows down a thin layer of that flowing gas, causing it to roll forward on itself. By the time it exits the cylinder, it's formed into a self-contained donut shape, which it is able to maintain as it flies through the air - even when subjected to cross winds.

Indian inventor creates children's science toys from trash

By Ben Coxworth

Children in the First World have a lot of choice when it comes to scientific toys. In fact, there are whole stores devoted to selling things like robotics kits, ant farms, and simple microscopes. In the developing world, however, such fancy toys are relatively scarce. So, what's an adult to do if they want to get the local children interested in the sciences? Well, in the case of Arvind Gupta, they show the kids how to make scientific toys from trash.

Gupta's story began in the 70s, when he was an engineering student at the Indian Institute of Technology. While he was there, he volunteered to teach the children of the mess staff, who couldn't afford a formal education.
Upon graduation, he went on to work at Tata Motors, where he helped to build trucks. After five years of doing so, however, he decided that it wasn't the career for him. In 1978, he took a one-year leave from his job, and took part in the Hoshangabad Science Teaching Program. "The objective was to make science fun and exciting for village children using simple, low-cost materials available in their environment," he told us. "This experience had a profound impact on me. I thought it was much more satisfying than making trucks."

Portable device instantly detects diseases

By Bridget Borgobello

Infectious diseases these days seem to have gotten a lot of attention, with media hype and threats of pandemics often being portrayed in apocalyptic sci-fi movies. We all know that several types of these diseases can spread rapidly, and it is crucial that doctors be able to identify them quickly in order to prevent an epidemic. Unfortunately, current testing methods can take hours and even days, delaying the process of adequate prevention. It should then ease your mind to hear that researchers at the University of Tennessee have invented a device that can rapidly detect these unwanted afflictions.

Constructor robot assembles and disassembles structures as it climbs

By James Holloway

Researchers at Cornell University have built a robot prototype capable of navigating a three dimensional truss structure, disassembling and reassembling the structure into new forms as it goes. The project hints at a possible future when buildings and robots may be designed in close harmony for autonomous buildings maintenance.

The robots are fitted with specialized 3D-printed bi-directional gears and joints tailored specifically to the structural components. They are hinged at the middle allowing them to flex through ninety degrees in order to navigate from vertical to horizontal rods and vice versa. They are also equipped with a rotational mechanism allowing them to twist around the pole as well as to unscrew rods from the structure itself.
