Charge - Shaken not Stirred!

Filed under: Royal Mumble, Technology - roshabraham @ 9:46 am

Couple of days back, I happened to read an interesting article on TechTree.com.
It talked about the ability of devices to generate electricity by subjecting it to physical or mechanical stress.

Dynamo powered radios, torches and even mini-computers that are charged by turning a mechanical handle for few minutes are quite common these days.
But, the shake and charge is an interesting concept none-the-less.

Here is the article from TechTree.com :
"If a bunch of ingenious researchers are to be believed, the day isn’t far when most of your gadgets would be powered by nanogenerators- tiny zinc oxide wires that possess piezoelectric properties.
If that went over your head, let us explain. Piezoelectric properties point toward the capability of an object to generate electricity (albeit tiny amounts of them, at least for now) when the object is bent, stretched or when subject to any physical or mechanical stress.
In short, with this capability added, any object that can "move" can be made capable of drawing power from the movement itself. The nano wires used to power these future gadgets possess the aforementioned piezoelectric abilities and are not only very small in size but also very thin. Each nanowire is 25 times thinner than a human hair!
The lead researcher behind this project, Zhong Lin Wang, believes that the device can be in the future used to power cellphones and gadgets.  Imagine, being able to charge your phone by merely moving it or shaking it? Even though these might sound farfetched now, a few years down the line, this might just become routine.
Apart from their use in charging gadgets, nanogenerators could be used in defense technology and biomedical sciences. Wang also demonstrated a video in which a single nanowire attached to a hamster managed to create 70 millivolts (.07 volts) of electricity.
Although this might sound too insignificant now, the team has managed to generate up to 0.2 volts of electricity, and with further improvements expected, the figure is sure to go up. Just to put things into perspective, a USB powered device uses about 5 volts of electricity. So I guess we still have a long way to go."
 
Cool. Ain’t it?

Holy Week

Filed under: My Life, Royal Mumble, Religion - roshabraham @ 9:08 am

I have been supporting India Campus Crusade for Christ for some time now. They are doing a wonderful thing by spending time with the youth and educating them the Word of God.
In a world where there is so much chaos and disharmony, it is good to know that the youth are being led the right way.
Let’s pray that God will bless their Ministries abundantly.

I got this beautiful message from Joseph Wilson who is a part of the Campus Crusade Mission.

‘Every part of Scripture is God-breathed and useful one way or another - showing us truth, exposing our rebellion, correcting our mistakes, training us to live God’s way. Through the Word we are put together and shaped up for the tasks God has for us.’ 2 Tim 3:16

Father God!
I know that I have committed many wrongs in my life. I repent for all my sins.
Father I believe that whosoever comes to you will not go empty handed.

I believe that I will find ‘your amazing grace‘ that will fill my soul and cleanse my heart of all evil and sin.
I submit myself into your care and protection of Lord. I believe that you will lead me through my life, helping me overcome all obstacles that come my way.
Lord I am like clay in your hands. Mould me in a way that you want me to be. I believe that your skillful hands will repair my broken life and cleanse me of all iniquities.
Thank you Father, for listening to my prayers.

May this Holy Week transform our lives and give us everlasting peace.

God Bless.
