Even though many people only associate solar power with dark, silicon cells, the technology will likely have altogether different appearances in the future. For example, some solar power technologies come in a liquid form that can be sprayed onto arbitrary surfaces. Colloidal quantum dots (CQDs) could be applied this way, but the actual spraying process is complicated, but researchers at the University of Toronto are changing that.

Traditionally batch processing is used to apply CQDs to a surface, but this is a somewhat slow and inefficient process, as it requires multiple stages. What the Toronto researchers built with airbrushes and a spray nozzle used in steel mills is able to do the same job, but very rapidly and efficiently, in a roll-to-roll method. This would also make adding these solar cells to other manufacturing processes much simpler.

The researchers ultimately want to see backups capable of spraying solar cells onto roofs, but that is still a ways off. As that is developed though, CQDs will also see their own performance improved, making for a more powerful combination.

Amazon has just launched a new program on its website that allows consumers to haggle prices with third-party sellers over select products, which currently includes items such as sports jerseys, autographed posters, collectible coins, and fine art. The program, known as 'Make an Offer,' allows consumers to suggest a reduced price for items that are sold by third-party sellers who participate in the program. The haggling itself occurs through email after an Amazon user submits their offer for an item to the seller. Once a final price is agreed upon, Amazon provides notification for the consumer to add the item to their cart so that they can complete the purchase. Throughout next year, Amazon plans to expand the new negotiation program to hundreds of thousands of items, though it is not currently known if technology products will be included in the expansion.

It is worth noting that the 'Make an Offer' program is not meant to act as an auction, as users interact one-on-one with the seller and will never pay more than the listed price for a product.

The ability of geckos to adhere to just about any surface has inspired a number of technologies, such as special gloves. There has been a question though, about whether geckos must apply some force for the adhesion to work. Researchers at the University of California, Riverside put this question to the test by measuring the adhesion strength of living and dead geckos.

The reason geckos are able to stick to almost any surfaces has to do with what are call van der Waals forces. These are the very small forces between molecules that can actually pull them together. To take advantage of them, gecko toes are covered with hair-like structures called setae that can actually require an electron microscope to see in detail. While these setae provide the clinging forces, some have believed that some active component is also required, such as using muscles to push the toes against the surface. By using a device to measure shear forces, the Riverside researchers found no difference in strength between living and recently-dead geckos. However, living geckos will hyperextend their toes to reduce adhesion, to prevent injury.

What this research translates to is that geckos use no energy when clinging to a surface, such as when they are sleeping. That adhesion can be entirely passive could influence many technologies.

Street Fighter V was confirmed by Capcom over the weekend and in doing so revealed that the game will be exclusive to the PlayStation 4 and PC platforms. Microsoft Head of Xbox Phil Spencer addressed the exclusivity deal over the weekend tweeting "Business deals happen. We won't do all of them." He further added "When we have a 1st party franchise in a genre I'd rather invest in ours," referring to Killer Instinct, which is owned by Microsoft. Spencer rounded out his thoughts on exclusivity saying, "I'd love it if Xbox fans could play all the games, but business just makes some deals happen. It's all part of competition... I appreciate the competition, they do good work. I just focus on us and like you say I think that makes us better." Only time will tell if SF:V will make its way to the Xbox One, but until then gamers will have to make due with what choices are available to them or purchase multiple consoles.

Sony was the victim of another hacking attack last night, targeted at the PlayStation Network, an occurrence that appears to be happening more frequently. Sony said it was "investigating the root cause for the issue," while the group known as Lizard Squad claimed responsibility posting to their Twitter account "PSN Login #offline #LizardSquad." Sony Pictures was the victim of a massive attack last week where hackers stole about 100TB of data including employee Social Security numbers, internal files, and multiple upcoming Sony movies. Hacktivist group Guardians of Peace claimed responsibility for the attack today in response to the upcoming movie The Interview and demanded that Sony stop "immediately showing the movie of terrorism which can break the regional peace and cause the War!"

It was recently revealed that Sony was selling a limited edition of the PlayStation 4 video game console to commemorate the 20 year anniversary of the original PlayStation. The limited edition of the console, dubbed the PlayStation 4 20th Anniversary Edition, managed to fetch an amazing $20,100 on eBay over the weekend following 34 bids. Another seller was able to sell their limited edition version of the PlayStation 4 for $15,100 after 106 bids were placed for the console. Although Sony released the PlayStation 4 20th Anniversary Edition for $499, consumers are purchasing the console for amazingly high amounts because the 12,300 units originally produced sold out quickly during preorders.

At the recent Game Awards 2014 show, The Witcher 3: Wild Hunt was named as the Most Anticipated Game. It looks like that anticipation is going to have to hold out a bit longer as the Board of CD PROJEKT SA has released an open letter announcing a 12 week delay.

The letter explains that there are still details to be corrected and even with everyone "working at full speed," they must shift the release date to May 19, 2015. The letter also states that this will be the studio's most important release in its history and that they want it to be "one of the best RPGs you will ever play." It goes on to say "we apologize and ask for your trust." This is actually the second time the game has been delayed.

While it is disappointing that we have to wait even longer, at least this will give us more time to finish playing The Witcher and The Witcher 2: Assassins of Kings, and any of the games we picked up in the recent Steam sale. You can read the full letter at the source link.

Even in this digital age, filled with displays, paper is still used with potentially 90% of all business information still being recorded on it. Typically this paper is discarded after one use, which makes some sense as you can only print on a page once, right? Researchers at the University of California, Riverside have created a rewriteable paper that could obviously reduce waste quite efficiently.

This new paper is made out of glass or plastic and contains a redox dye, a catalyst, and a thickening agent. Redox dyes are chemicals that are colored when oxidized, but when reduced, meaning they gain electrons, become transparent. Combined with the catalyst and thickening agent, it is possible to use ultraviolet light to cause this reduction, so the colored, opaque sheet will become transparent where the light reaches. By heating the paper to 115 ºC, the dyes are oxidized and return to their original coloring, removing what was printed on them. Considering laser printers can already heat paper up to 200 ºC, this erasing processing is quite feasible.

Currently the paper is only able to be rewritten 20 times before there is a significant loss in contrast or resolution and the printing will fade after three days. The researchers are working towards the paper surviving 100 cycles and extending the legibility beyond three days. They are also confident that it will be possible to print on the paper in multiple colors, though currently they have only worked with single colors.

British company Imagination has announced a barebones computer to compete with the Raspberry Pi. The Creator CI20 beats the Pi in processor speed, memory, and onboard storage, and also has Wi-Fi and Bluetooth for connectivity while many competitors only have wired Ethernet. The CI20 is available for purchase now, with shipment expected to begin in January, at an MSRP of $65. Imagination has previous experience designing graphics chips for Apple devices and will use a graphics chip found in iPads for the CI20. Chris Green, principal technology analyst at the Davies Murphy Group, described its' potential impact saying, "There will be a modicum of pick-up, especially for people trying to develop for Android it could be a very useful low-cost device to have. But do I think it will make much wider impact? The answer is no."

Everybody is likely familiar with lithium batteries because they are such a ubiquitous energy storage system. What fewer people may know though is that they are very hard to improve and that one method to do so presents serious issues. Researchers at the Pacific Northwest National Laboratory however, have recently found out why a specific coating can improve that method's effectiveness.

Normally lithium batteries rely on graphite electrodes to absorb and release the lithium ions, thereby storing and releasing electricity. Silicon electrodes can potentially hold ten times as many lithium ions though, and could allow for batteries with many times the life we have today. The problem is that silicon is so fragile that the swelling it undergoes when taking in the lithium ions breaks the electrodes. Silicon nanoparticles can help, and also offer even better performance, but still suffer the fracturing problem. Researchers at the National Renewable Energy Laboratory and University of Colorado, Boulder have found that a rubber-like coating of aluminum glycerol protects can let the nanoparticle electrodes survive five times longer. Now, thanks to PNNL, we know why.

Uncoated silicon nanoparticles will have an oxide layer on their surface, which restricts their ability to swell, but the aluminum glycerol, or alucone, actually removes that oxide layer is allows for the swelling. The researchers also observed the alucone preventing the nanoparticles from merging, which was another issue that would damage the electrodes.

In the future we may have advanced quantum computers capable of running algorithms that modern electronic computers could never hope to. There is still a lot of work to be done before these devices can become reality though, including finding ways to store and read quantum information. Now researchers at the Technische Universitaet Muenchen have found a way to access the information stored in nitrogen vacancies electronically, which has never been accomplished before.

Nitrogen vacancies are a defect found in diamonds where carbon atoms have been replaced by nitrogen atoms. When the nitrogen atoms are hit by a laser, an electron is popped up to a higher energy state, creating an electron-hole pair that can store quantum information. To access this information, the researchers used nanodiamonds and a layer of graphene. When the electron-hole pair, which acts as a dipole, formed in the diamond, another dipole formed in the graphene, which is highly conductive. Gold electrodes are then able to record the induced charge, thereby measuring the information electronically.

As the electron-hole pairs will disappear in a matter of nanoseconds, the researchers had to use a laser that reaches into picoseconds and use very sensitive equipment. Such a combination should allow it to future quantum computers to achieve clock speeds in the terahertz domain, if this system is used.
