Using air to charge cellphones?
Using air to charge cellphones? IIT-Delhi does it!
All you need to charge your mobile is -- air!
Students at the Department of Industrial Design at Indian Institute of Technology, Delhi have attached a turbine with a mobile phone that helps charge it even when the user is travelling.
"The electricity generated by the turbine when moved by wind energy could charge a cellphone in an emergency. It generates electricity to the tune of 3 to 4 watts which is sufficient to charge a mobile phone."
The specially designed turbine, which costs about Rs.200 to be developed inside a laboratory, is so small that it could be easily kept in a pocket.
The primary objective of the device is to extend mobile 'connectivity' where there is no electricity. The device also saves energy, though not to a significant extent.
The device is best suited for coastal areas where the wind flows almost continuously.
The technique is not yet commercialized but the department has sent a proposal to the ministry of science and technology to help manufacture the turbine on a large scale.
"The device will help mobile phone users charge their phones while travelling in a bus, a car or a train. All they need to do is -- place the turbine against the wind flow. It will use wind energy to move the turbine thereby generating energy."
The students have also used a spring in the device that can store energy through a handle. It could be used to charge a mobile during power cuts.

WatchMojo : Useful Site to Learn by Watching Videos
Knowledge is Power and this power comes with learning. Internet is full of Websites, which shares useful information and a Google search could let you find anything you ever wished to learn. Though, having a single resource where you can learn many new things is always great. I usually spend lots of time on Youtube to learn various things by watching How to videos. One of my particular area of interest is to learn about things which I use in day to day life, that includes learning how to cook, history of my favorite music star and band World history and so on.
Meet WatchMojo: Web Video Magazine
I love reading but videos are always more interactive and better way to learn new things. Remember, scene from a movie clip which you have seen 10 years back or do you remember, how easy it was to remember Apple in your kindlegarden by seeing the pictures. I have already talked about benefits of Video Blogging and from a user perspective, I always like to watch new videos which let me learn something new.
Couple of days back, when I was watching few How-to videos on Youtube, I stumbled upon video from this site (Watchmojo.com), which is a portal, where they product various professional videos on How to, people, Person, history and many more. After watching one video, I spent almost 3-4 hours that particular day watching various different videos and brushed up my knowledge.
I never knew about the history of Lady gaga, never knew how David guetta become a sensation or Warren Buffet biography. Watchmojo offers various videos on different topics and I’m sure you will end up finding something new to learn today by watching videos.
Here are few videos from their Video channel:
Watchmojo was founded in 2006 by Ashkan Karbasfrooshan, and founder of Askmen.com, before he sold it.
I’m sure many of you who like learning something new by watching videos, you would love to watch various videos on WatchMojo.
