Solar Sinter, 3D Printer That Uses Sunlight to Melt Sand Into Glass


Markus Kayser
Solar Sinter Concept 


In our world with shortage of energy production and raw material which is of great concern, a project exploring the capabilities of desert manufacturing, has surfaced where energy as well as material seems to be in abundance. The project was developed by Markus Kayser during his MA studies in Design Products on Platform 13 at the Royal College of Art and built by him the `SolarSinter’ concept is not too dissimilar from laser sintering printers which are used in operations such as SpaceX for printing impossible objects from metal.

 A focused sun beam is less precise than a finely honed laser though the core concept remains the same. The product designer, Kayser from Hannover, Germany, had his solar powered sand printer taken to the Egyptian desert to portray how it functions. On harnessing the power of the Sun, he heated ordinary sand into glass to create natural and unique 3D objects.

In the experiment, sunlight as well as sand is used as raw material and energy in order to produce glass objects with the help of a 3D printing process, which combine natural energy and material with high tech production technology. Solar sintering would give rise to questions about the future of manufacturing, giving way to dreams on the full extent of the potential of production on the world’s most capable energy resource which is the sun.

Two Elements of Desert - The Sun & Sun

It was in August 2010, when the first solar machine – the Sun-Cutter was taken to the Egyptian desert in a suitcase which was a solar powered, semi-automated low tech laser cutter which used the power of the sun to operate it and directly harnessed its rays through a glass ball lens to `laser’ cut 2D components with the use of a cam guided system.

The Sun-Cutter created components in fine plywood with aesthetic quality of curious hybrid of machine made and nature craft because of the crudeness of its mechanism as well as the cutting beam optics together with variation in solar intensity and the outcome of the weather fluctuations.

The sun and the sand are the two elements which rule the desert world wherein the sun offers a huge potential of large amount of energy source while the sand with unlimited supply of silica in the form of quartz. This provided the experience of working in the desert with the Sun-Cutter directly with the new machine which brought together the two elements, where on heating silica sand to melting point and enabling it to cool solidified as glass.

Sintering – Central Process in Design Prototyping

This process of conversion of powdery substance through heating process to a solid form is called sintering and has become a central process in design prototyping in recent times as 3D printing or Selective Laser Sintering – SLS.

Laser technology is used in the 3D printers to create precise 3D objects from various powdered plastics, metals and resins since they are appropriate counterparts of computer drawn 3D designs data by the designer. With the use of the sun’s rays rather than laser and sand instead of resins, an entire new solar powered machine and production process in making glass objects which can tap into the vast supplies of sun and sand is found in the deserts.

In February 2011, the first manually operated solar sintering machine was tested in the Moroccan desert with good positive results leading to the development of the present larger as well as fully automated computer driven version – the Solar Sinter.

Successful Teleported Quantum State of Proton

Quantum State of Proton Teleportation
A team of physicist for the first time have successfully teleported a quantum state of photon to a crystal over 25 km distance through a fibre optic cable showing effectively that the photon’s quantum state, is important to the teleportation process and not its composition.

Nicolas Gisin of the University of Geneva, successfully lead his team and the results were published in the journal Nature Photonics which squashed the earlier record that they had set a decade ago by teleporting a quantum state of a proton 6 km.

The quantum teleportation is a process wherein the quantum information which is the exact state of an atom or photon, is transmitted, in principle from one area to another with the use of classical communication with the earlier shared quantum entanglement between sending and the receiving location.

Since it is based on classical communication, which tends to proceed not faster than the speed of light, the same cannot be used for superluminal transport or communication of classical bits. It could also not be used to make copies of system since this may violate the no-cloning theorem.

Teleportation – Form of Transportation/Communication

Current technology offers no possibility of anything resembling the fictional form of teleportation even though the name is inspired by the teleportation which is used in fiction.

One could think of teleportation as a form of transportation or a kind of communication providing a way of transporting a qubits from one location to another without the need to move a physical particle with it.

The photon’s quantum state is cable of preserving information under extreme conditions which include the difference between travelling as light or stored in the crystal form matter.

The photon’s condition acts as information which can be teleported towards great distances with the use of the optical fibre and can be stored within the crystal which is achieved due to the phenomenon in quantum mechanics called entanglement when two particles have a correlation inspite of not touching and transmitting information to one another.

Quantum State - Controls Quantum Physics 

In order to test this, ensuring that they observe what occurs, one photon was stored in a crystal and the other was send along the optical fibre at a distance of 25 km. and the photon which was sent along the optical fibre collided with a third photon presumed to destroy both of them.

But the information derived from the first photon was transferred to the third photon in the collision just as in the case of a billiard ball being hit by another for transfer of energy. The information from the third photon returned back to the crystal where it was measured ensuring that the information was preserved between the first and the second.

Gisin’s team mate, Felix Bussieres in a press release states that `the quantum state of two elements of light, the two entangled photons are like two Siamese twins, a channel which empowers the teleportation from light to matter’, irrespective of the information being in crystal or light, making no change to the information.

This would mean that the quantum state not the physical state, controls in quantum physics. Quantum entanglement being the basis for theoretical quantum computing as well as quantum communication perhaps will take a long time for the results to have real world implications and the achievements of Gisin’s research could help to improve how quantum entanglement interactions could be measured.

Keecker- Interesting Machine That Can Move Around Your Room


Keecker
Keecker is a type of mobile computer  Robot that consists of a projector along with an audio structure on a mobile base and also a group of potentially attractive sensors. However, its designers do not imagine it as a robot. CEO, Pierre Lebeau stated that robots are often portrayed as utilitarian and mechanized man’s tasks, and it is not parallel to Keecker. In fact, they really deemed Keecker as the development of computers and it is 100 percent made for a house or collective atmosphere.

Some hardware and software of the system-

It is a number of sensors and figures that is utilized to help this Keecker to be in motion, lock-in on people and keep away from obstacles. The manufacturers apply a combination of infrared with ultrasound signals, manifold camera imagery system and also Wi-Fi network method and many more.
The machine possesses some of the autonomous abilities.

Keecker shifts from one room to another room and can remember definite spots in your home. Therefore you can order it to go from one spot to another in only one click. You may even manage this Keecker yourself from your own Smartphone even though you are not at home. It is because it will run its camera to your handset and will allow you shift it in actual time.

Keecker can moreover be programmed to shift from room to room in the day or at night to test if all is normal. When the charge of battery is low, this device goes back to revive itself.

In accordance with Lebeau, while you first take Keecker into your home it starts moving around, by means of a 360-degree camera on its head to work out the ground space. When that mapping is finished, you may name every room, then you can point Keecker to move there with the valve of a switch. Lebeau was motivated by cleaning bots such as the Roomba, but he did not want Keecker to be exactly the same. Roomba can just hit into the wall and it is very stupid-like.

When you are out of the home it can be set to identify motion and check temperature, moisture, and CO2 amount. It can also change your babysitter, or even let you to simply keep a watch on her from the ease of your Smartphone. This device also contains a microphone, permitting it to act as a center for video calls or get voice commands. You can connect it with your phone via Bluetooth.

Length of the device-

Keecker is a supple, plastic orb that is about eleven inches broad and sixteen inches in length. It goes around the floor on a couple of wheels, which make it appear like a remote. You can manage it on your phone through an app for iOS system or Android.

Thus, when bring home this HomePod, Keecker and take it out from its container, it would start to look around, examining every part of the room. Later, you can instruct it to go to a specific position in your house, from your app.

Sony Patent For Electronic Mirror Device And Electronic Mirror Program


An electronic mirror is really an electronic machine that works as both a TV set and a mirror simultaneously. In many hotels, it is seen that flat screen televisions are exactly placed right in the center of the mirror, occupying most part of the space, leaving only some spaces near it for seeing anyone’s reflection.

So, it would be better if a TV can be converted to an original mirror at only one click of a finger. Well, the mirror TV takes that concept one-step beyond, with the mirror itself becoming a television set at a click of a finger. The lavish hotels that cater to the discriminating customers can embraced this modernization, which merges technology and sophisticated set and also a mirror- all at once.

A patent application US20130314581 was filed regarding this new type of electronic device- an electronic mirror. According to the patent,the device will really work just like mirror, as it would reflect the user. Here, actually a TV set will do the work when it is in switch of mode.

Need of Such Device

A TV set with a flat-panel display machine, when not utilized, is just a stationary piece of a blackboard and otherwise it has no extraordinary use. In case of the TV set, a well-designed and multifunctional picture display device is present that can be used like a mirror for another function when it is not utilized as a display machine.

This multifunctional image displaying device comprises a liquid display machine and a half mirror, within which the half mirror usually runs as a mirror, and on identifying a person moving, the liquid display tool shows motion picture.

But the half mirror had some problems, and therefore there was a demand of an electronic mirror machine that does not get darkens when utilized as a mirror and helps the object to appear more beautiful than ordinary mirrors perform. This mirror works through an electronic mirror display technique along with the electronic mirror program.

System of the device-

It is to be noted that the electronic mirror device of this patent would consists of a camera, a display unit, along with a control unit that exhibits a screen image of an individual recorded by the camera unit on a primary portion acquired by opening the screen of the particular display unit.

It shows a basis of light for lighting the individual on a second area, and regulates an intensity of the light source in proportion to the sex and an age of the individual, identified by examining the screen image. In this electronic mirror device, the second area is placed in left sides and right sides and also in top or bottom sides.

The control unit of the electronic mirror does the function of eliminating a backdrop by cutting a picture of the individual out of the screen image trapped by the camera unit. This control unit has also the task of reversing the left as well as the right parts of the screen image of camera.

It even alters the emission color of the source of the light in the second area to control the image quality of the camera.
