Water: - Now a Cell Phone Charger


Water Cell Phone Charger
Cell phone: - The Power Issue: -

Cell phones have become indispensible in the last decade or so. Cheap prices along with a wide range of choices have resulted in almost everyone having a cellphone. But even though life has become a lot easier thanks to this device, people nowadays have to face a new challenge, the challenge of keeping their phones adequately charged.

Though charging is a fairly while at work or at home, it becomes difficult when people are outdoors, i.e. away from power outlets. Even though power banks have solved this dilemma to some extent, they still have certain flaws regarding their affordability/availability.

Thus it is clearly seen that there is a need of a device which can easily charge cellphones by harnessing something which is naturally available or something which is not directly related to a power source. Water covers more than 2/3rds of our planet’s surface & is present in abundance in our surroundings & it would be amazing if a device can be invented which could utilize this abundance & harness power from it to run our cellphones. Researchers at the Massachusetts Institute of Technology (M.I.T.) have helped mankind realize this dream.

Mechanism: - 

Researchers namely, Nenad Miljkovic and Evelyn Wang have come across the fact that when water drops jump spontaneously while coming in contact with super-hydrophobic (water repelling) surfaces, during condensation, they carry an electric charge.

They also stated that a device consisting of interleaved plates can be created to utilize this fact to power cellphones. As water droplets will jump, they will come in contact with one plate & another carrying their charge.

This chare can be harnessed as power by constructing an external circuit across the said plates. The device can be made of any conducting material, even something as cheap & abundant as aluminium, thus potentially reducing its cost. Another perk of this system is that it can also produce clean water.

In humid environments, this device can simply harness power from the surrounding atmosphere provided that a temperature difference exists between the surroundings & the device for condensation to take place.

Even though the process will be time consuming, it is a boon for people who have to operate in remote areas where conventional power sources are difficult to come across. It can also be use to power remote, automated environment sensors.

Implications: - 

Once a producible version of this device is available, a huge part of energy crisis will be solved also as people will no longer have to depend on fossil-fuel generated electricity. The energy harnessed will be clean, cheap & virtually infinite in terms of amount & availability.

Pollution issues will be solved to some extent as well. Clean water, another compelling requirement in today’s world can be generated as well thanks to this device.

People will be tension free when it comes to keeping their cell phones powered 24*7. Thus, once again technology comes to the rescue to rid mankind of misery & improve the quality of life.

SmartPhones Sensor: Helps Generating Crowdsourced Pollution Maps

Pollution Maps
Science is progressing daily. Every second of every day someone in some part of the world is creating something new and innovating. But Science and technology have its backlogs too. One of the major side effects of developing technology is pollution.

The irony is to compact these side effects we need the help of science. In the Kalsruhe Institute of Technology, a technology is being developed that will enable the smart phones to measure and determine the level of particulate matter present in the atmosphere. But the accurate calculation of the particulate level in the atmosphere for a crowded city or a large region will need conservable amount of manpower.

THE IDEA: 

The idea is to attach a sensor to the smart phones that will calculate the particulate matter level in the atmosphere and in turn generate effective pollution maps for that particular area. The idea is still under consideration and the research is going on this particular topic. But what is yet to be determined is exactly how many persons will be required for this project to generate a reliable and accurate pollution map for a certain area.

THE PROGRESS: 

Kalsruhe Institute of Technology is not the first intuition to work in this field. Other institutions have worked on a similar idea before Kalsruhe. At the University of California, a project was undertaken by a group of researchers who explore the same idea. Back in the year 2010, smart phones were used to read the levels of particulate matter and researchers were under the impression that by installing an app in the smart phones, light could be emitted via the LED’s flash from the built in camera and photos pertinent to the topic were analysed.

The researchers at KIT went further ahead and attached a light trap to the concerned phone to receive more accurate and reliable results. A low cost dust sensor was also adapted.

In another year or two , researchers hope to develop a production version of this product with a newer version of the sensor that will calculate fine dust along with course dust. Photos could also be stored and preserved in the future version increasing the effectively of the product. This form with be supported by a magnet which will suit the needs of the application in the smart phones.

THE PROBLEM: 

In spite of all this, a slight problem still remains. This application will be used by the general public and researchers are doubtful about how this application will be used by the public.

No matter what the negative consequences of the application might be, this is certainly a ground-breaking idea in the field of science. This will help to solve a number of health issues especially in over populated and busy cities. With the help of accurate pollution maps, necessary measures could be taken for a particular region to protect and preserve their environment. The health department could concentrate on a particular area with this app.

Moreover, since they are coming with a Windows 8.1 combination, things become simply smoother and faster. One can track the daily activities on the go, no matter which place is it or what time is it. Also with the help of this App, users can measure themselves against the present Fitbit friends.

A Wise Decision

The introduction of the Fitbit App is really useful as well as important in order to stay ahead in the competition. Like in Android and IOS phones, Microsoft in order to hold an important and competitive rank in the smartphones market, needed to take this step.

In each aspect, this step taken by Microsoft is indeed a wise one. It breaks free from the conventional Apps that are generally presented by the Windows, like Xbox games and social networking applications. Microsoft like always thus is successful again to present a literally “healthy” competition.

Types of toner cartridge:
 
Canon
A few top companies that manufacture printers are HP, Epson, Canon, Lexmark, Brother, and Samsung. The not only manufacture printers, they also manufacture toner cartridges. Also, there are a number of companies selling toner cartridges apart from the original manufacturers. However, the best option is to choose the original equipment manufacturer (OEM) cartridge as it is not only compatible with your printer, but also saves you the uncertainty of your cartridge running out or getting non-functional during the hour of need. The only hindrance in choosing an OEM toner cartridge is that they are comparatively expensive. There are other options as well, like remanufactured toner cartridges, where-in toner cartridges are made up of recycled or refurbished parts of an old toner cartridge.

They are reasonably priced as compared to an OEM toner cartridge. However, one cannot vouch on its performance. Apart from these two, there are generic toner cartridges as well, but they are very uncertain in their performance and if it so happens that they are not compatible with the printer. It might hamper the performance of the printer as well. So, usually people don’t prefer generic toner cartridges for their printers. One more option is the refill toner kit, but the same being very expensive and complicated in exercising; it is best advised to stay away from this option.

Pricing and sustainability:
 
Toner cartridges are usually priced as per the page yield or the brand of the OEM cartridge. Page yield is the number of pages that can be printed before the printer runs out of the toner. As mentioned earlier OEM cartridges are mostly expensive. However, one can choose a more economic option by choosing a remanufactured toner cartridge, if someone has a budget issue. Remanufactured toner cartridges are usually available for half of the price of an OEM cartridge. Many stationery stores offer wholesale discounts or quantity discounts on toner cartridges.

So, bulk purchase can also help in cost saving. The only care to be taken is to store toner cartridge in the right position and under the right temperature, as sunlight and heat can cause serious damage to the toner particles. Another good way to buy a toner cartridge is to order it online. Online stores offer a wide range of OEM, remanufactured, generic toner cartridges and refill toner kits. They make it super simple as they offer a wide range of products to select from but also enable a person to choose the exact specific toner for their printer. Additionally, online stores offer good discounts on the products. It is easy and convenient and you get your toner cartridge at your door step.

Now, mere choosing the right cartridge isn’t enough, one needs to maintain the toner cartridge properly. So, below are a few check points that can help in maintenance of your toner cartridge and your printer.

1. If your printer is showing low toner levels, don’t rush in to installing a new cartridge. Always check for clogged nozzles, clean the cartridge with a damp cloth and also change the font settings. Reinstall the cartridge and try running it once again.

2. Before installing a new cartridge, shake it gently or rock it side by side. This ensures that all the powder is evenly distributed before the cartridge is installed.

3. One has to keep a check on the printer settings, make sure ‘toner saver’ mode is on. The font is ideal font without much bold and large font text. Also, the printing should ordinarily be done in the draft mode.

4. Nevertheless, the use of paper should be optimum and printing should be done wisely. As it is best to save paper than to waste it.

Firefox Apps being Repackaged by Mozilla to Make them Usable by all Android Users!

About Mozilla

Mozilla is a well-known company, which is a part of the free software community. It is popular for making the widely used browser- Mozilla Firefox.

This community is known to use, develop, advertise and support Mozilla products. It thus promotes availability of free software and open standards having nearly negligible exceptions. The Mozilla community is institutionalised under the Mozilla Foundation.

Apart from the browser, Mozilla has also produced Thunderbird, Firefox OS for mobile devices, Firefox Mobile, Bugzilla, i.e. the system used to track down web bugs.

About repackaging Firefox OS apps for Android: 

This company has now undertaken the endeavour of repackaging Firefox OS apps to make them compatible with and usable in the Android platform.

Mozilla aims to make Web apps and Open Web Apps the epicentre of smart phone experience by making use of the Firefox OS.The devices with the Firefox OS is cheaper than other modern day smart phones. Survey says that Android is the most popularly used mobile phone OS.

By repackaging the Firefox apps for the android platform, the company is delving into a new realm. Previously, it had already made packages of the Firefox OS apps to suit the desktop OS such as Windows, OS X, and Linux etc. It is their first attempt in repackaging for mobile OS.

It has already launched the repackaged apps. All the users of the repackaged Firefox OS apps in android platform are able to download and install the apps from the Firefox Marketplace. These apps will behave like all other commonly used Android Apps.

A developer gets the provision of making his own personally customised Open Web App for Firefox OS devices and make that app available to millions of users of Firefox for Android users all over the world. The developer does not have to change a single line of code, making his task so much more user.

To install and use apps that have been repackaged, the user has to allow unknown sources to make the installation of the app.

The repackaged apps have been built using HTML5. They are different from the native apps found normally on Android, iOS or Windows platform. At the initiation of making Firefox IS, Mozilla made use of Boot 2 Gecko.

Get yourself acquainted with the company's plans and undertakings: 

The Mozilla Company has expressed its wish to make the Firefox OS apps compatible with the iOS platform too.

But the iOS platform does not possess the option of installing a web browser that is Gecko-based. This sort of web browser is essential for support Open Web Apps and its unavailability is preventing the repackaging of the Firefox apps in the iOS platform.

So that iOS compatibility can be achieved, Mozilla has collaborated with Apache Cordova. Mozilla has been reported to have signed deals with companies in India and Taiwan so that it can market its devices in these countries.
