This Spit-Powered Battery Requires Just A Drop Of Saliva
The idea of spitting out your torch to get the light for 20 minutes may not be very attractive, but scientifically correct. As you can also replace saliva with dirty water to get even more energy.
The saliva or dirty water fed batteries are already a reality. A group of scientists from Binghamton University in New York, led by the researcher Seokheun Sean Choi, have developed disposable paper batteries that are recharged with dirty water or saliva. Actually, the source of energy is the bacteria that contain these liquids.
This battery has a curious origami ninja star design, which can be deployed to connect up to 16 batteries fed with dirty water or saliva. You can see it in this video:-
The battery, which is completely disposable, contains microbial energy cells that feed on the energy generated by the cellular activity of bacteria. At first, the energy obtained by this method was of the order of some nanowatt, but in five years of investigation, they have obtained a recharge of several microwatts per square centimeter. Connecting 16 batteries to each other by means of the pop-up design seen in the video, you can charge an LED flashlight for 20 minutes with a few drops of dirty water.
This improvement allows substituting the dirty water for saliva, easier to obtain although with less energetic power, generally in the saliva there are fewer microbes and bacteria than in the dirty water.
Researchers at Binghamton University have already found practical applications to this discovery. In emergency situations, for example, if you have lost yourself in a forest and your battery has run out, or it is too cold or too hot to use a standard battery, the battery powered by saliva or dirty water could be the salvation. Likewise, because of disposable paper, they are useful for making paper-based biosensors, such as pregnancy tests or HIV testing.
Seokheun “Sean” Choi and his team continue to work to perfect this technology and to generate more energy through bacteria. Reload the mobile with the water to scrub the floors? It sounds crazy, but maybe it’s not that far.

Android 8.0 OTA Updates Will Still Work Even If You Have 1 KB Of Space
When a system update arrives on an Android device, the first reaction from many people is, “Wow, am I awake?” And the second is: “Do I have free space to download this update?”. Typically, a major update may temporarily take up to more than 1 GB of storage.
However, let me tell you people, a good news about the tech giant Google’s upcoming Android operating system update, of course, the Android 8.0 will not make you worry about your space left on your device.
According to the media channel “The Ars Technica”, the latest version of the tech giant Google’s operating system Android 8.0 documentation clearly describes a feature called “streaming updates.” Basically, this new feature simply allows a new version of the Android operating system to be installed directly on the system partition, without requiring a previous download of the entire package.
In practice, this new extraordinary feature will simply decrease the gigabyte free space requirement to just 100 KB or even less than that. As we all know that the Android 7.0 Nougat arrived with a feature that allows you to update the system in a more transparent way.
As it works like this: there are two system partitions on your smartphone; One is partition A (you can save whatever you want, and it contains the current version of the Android operating system running), and the other is partition B (a reserved place where the original Android files are stored).
Today, in order to update Android, you need to download a large package in partition A, restart the device, and then wait a few minutes for the files to be replaced in partition B.
While with the streaming updates, you can simply continue to use your smartphone normally in partition A, as the System files are downloaded and updated in the background directly in partition B. Then after the download gets over just restart and use the new version of the Android operating system.
The tech giant Google documentation also tells you that the news will be released for Android 7.0 devices through a Google Play Services update – so we’re likely to see the news even before the release of latest version of the Android operating system, of course, Android O.
