  • New technology generates power from polluted air

    Researchers from the University of Antwerp and KU Leuven (University of Leuven), Belgium, have developed a process that purifies air, and at the same time, generates power. The device must only be exposed to light in order to function.

    "We used a small  with two rooms separated by a membrane," explained professor Sammy Verbruggen (UAntwerp/KU Leuven). "Air is purified on one side, while on the other side,  is produced from a part of the degradation products. This  gas can be stored and used later as fuel, as is already being done in some hydrogen buses, for example."

    In this way, the researchers respond to two major social needs: clean air and alternative energy production. The heart of the solution lies at the membrane level, where the researchers use specific nanomaterials. "These catalysts are capable of producing hydrogen gas and breaking down air pollution," explains professor Verbruggen. "In the past, these cells were mostly used to extract hydrogen from water. We have now discovered that this is also possible, and even more efficient, with ."

    The process seems more complex than it is; the device need only be exposed to light. The researchers' goal is to use sunlight, as the processes underlying the technology are similar to those found in solar panels. The difference here is that electricity is not generated directly, but rather that air is purified while the generated power is stored as hydrogen gas.

    "We are currently working on a scale of only a few square centimetres. At a later stage, we would like to scale up our technology to make the process industrially applicable. We are also working on improving our materials so we can use sunlight more efficiently to trigger the reactions."

  • should shut down sleep or hibernate your laptop

    Shut Down vs. Sleep vs. Hibernate

    Shut Down: This is the power-off state most of us are familiar with. When you shut down your computer, all your open programs close and the computer shuts down your operating system. A computer that’s shut down uses almost no power. However, when you want to use your computer again, you’ll have to turn it on and go through the typical boot-up process, waiting for your hardware to initialize and startup programs to load.

    Sleep: Also known as Sleep or Standby. In sleep mode, the computer enters a low-power state. Power is used to keep the computer’s state in memory, but other parts of the computer are shut down and won’t use any power. When you turn on the computer, it will snap back to life within just a few seconds. You won’t have to wait for it to boot up – everything will be right where you left off. However, this uses more power than shutting down or hibernating your computer.

    Hibernate: Your computer saves its current state to your hard drive, essentially dumping the contents of its RAM into a file on its hard drive. When you boot up the computer, it will load the previous state from your hard drive into its RAM. This allows you to save your computer’s state, including all your open programs and data, and come back to it later. It takes longer to resume from hibernate than sleep, but hibernate uses much less power than sleep. A computer that’s hibernating uses about the same amount of power as a computer that’s shut down.

    If you put your computer to sleep and its battery becomes critically low, the computer will automatically go into hibernate mode to save your state.

    When To Shut Down, Sleep, and Hibernate

    Different people treat their computers differently. Some people always shut down their computers and never take advantage of the convenience of the sleep and hibernate states, while some people run their computers 24/7.

    When To Sleep: Sleep is particularly useful if you’re stepping away from your computer for a small amount of time. You can put your computer to sleep to save electricity and battery power. When you need to use your computer again, you can resume from where you left off in just a few seconds. Your computer will always be ready to use when you need it.

    When To Hibernate: Hibernate saves more power than sleep. If you won’t be using your computer for a while – say, if you’re going to sleep for the night – you may want to hibernate your computer to save electricity and battery power. However, hibernate is slower to resume from. If you’re hibernating or shutting down your computer every time you step away from it throughout the day, you may be wasting a lot of time waiting for it.

    When To Shut Down: Most computers will resume from hibernate faster than they will boot up from shut down, so most people will probably want to hibernate their laptops instead of shutting them down. However, some computers or software may not work properly when resuming from hibernate, in which case you’ll want to shut down your computer instead. It’s also a good idea to shut down (or at least restart) your computer occasionally – most Windows users have noticed that Windows needs an occasional reboot.

    Making Your Choice

     

    Once you’ve made your choice, you can control what happens when you press the power button on your computer or close the lid on your laptop. To do so, press the Windows key, type Power buttons, and press Enter. You’ll see the power button options in the Windows Control Panel. (On Windows 8, you’ll need to click the Settings option on the search screen after typing Power buttons.)

  • Crack any WiFi password using simple steps

    It is very easy to find WiFi password using few cmd commands. This command works even when you are offline or you are connected to some other WiFi network. Using this command, we can further optimize our particular WiFi network like turning on some features such as mac randomization, changing the radio type of your WiFi etc.
    whenever we connect to a WiFi network and enter the password to connect to that network, we actually make a WLAN profile of that WiFi network. That profile is stored inside our computer along with the other required details of the WiFi profile.
    These steps work even when you are totally offline or you are not connected to the particular wifi you are looking the password for.
    How to know the WiFi password using cmd:
    1.Open the command prompt and run it as administrator.
    2. In the next step, we want to know about all the profiles that are stored in our computer. So, type the following command in the cmd:
    netsh wlan show profile
    This command will list out all the WiFi profiles that you have ever connected to.
    3. Type the following command to see the password of any WiFi network:
    netsh wlan show profile WiFi-name key=clear
    4. Under the security settings, in the ‘key content’, you see the WiFi password of that particular network.
    Besides knowing the password, you can also use this result to further optimize your WiFi. For example, Under the profile information, you can see mac randomization is disabled. You can turn on mac randomization feature to avoid your location tracking based on the device’s MAC address.

    Here is how to turn on mac randomization on Windows 10:

    1.Go to settings and click on ‘Network & internet’
    2.Choose the ‘WiFi’ in the left pane and click on the advanced option.
    3. Turn on the ‘Random Hardware Address’ feature under this settings. If your wireless hardware does not support this feature, the “ Random Hardware Addresses ” section will not show up at all in the settings app.
    Once you have turned this on, you are done.
    Also, under the connectivity settings, in radio type, you can see the whole list. Channel interference could be another reason for a slow WiFi. So, next time, you might also like to change the radio type settings for a better speed.
    As far as radio type is concerned, you can also change that in your router for a better connection or connectivity. 
    If you are also aware of some more tricks and tweaks like this, please put them in the comment below. We would be happy to feature some of those in our next articles

  • Scientists found first independent space nation 'Asgardia' - and you can become a citizen

    A consortium of scientists, engineers, entrepreneurs and legal experts has announced plans to create the first ever nation in space.

    The new nation will be called Asgardia - after Asgard, one of the Nine Worlds of the ancient gods ruled over by Odin in Norse mythology - and will be independent of any current nation state on Earth.

    Asgardia will be built on a satellite, which will be launched into orbit in the Autumn of 2017 - 60 years after the launch of the first ever satellite, Sputnik.

    It will have its own legal framework, flag and other symbols of nationhood, representing a new era in the "Space Age".

    "Asgardia is a fully-fledged and independent nation, and a future member of the United Nations - with all the attributes this status entails," said Dr Igor Ashurbeyli, chairman of UNESCO’s Science of Space Committee and founder of the Aerospace International Research Centre in Vienna, who is leading the project.

    "The essence of Asgardia is peace in space, and the prevention of Earth’s conflicts being transferred into space."

    Under current international space law, including the widely adopted , states are required to authorise and supervise national space activities, including the activities of commercial and not-for-profit organisations.

    Objects launched into space are subject to their nation of origin, and if a nation launches an object into space, that nation is responsible for any damage that occurs internationally and in outer space.

    The Asgardia project aims to create a new framework for ownership and nationhood in space, which will adapt current outer space laws so they are fit for purpose in the new era of space exploration.

    By creating a new space nation, the scientists hope to enable private enterprise, innovation and the further development of space technology to support humanity to flourish, free from the tight restrictions of state control that currently exist.
