No fluid batteries.

Was my question so stupid? The budding electrical engineer student’s mouth was open for a long time when I asked him whether saft lithium batteries are suitable to power air-conditioners. Later, after listening to him on various scientific facts about energy storing devices, I admitted to myself that my question crossed the frontiers of stupidity.

Generally, I know Lithium batteries are preferred for laptops and cam coders as both these gadgets are mostly used for long hours and nothing but lithium batteries are best suited for this purpose. In addition, Lithium is a light weight material that makes it ideal for portable batteries.

When the engineering student (he is actually doing a research in electric energy storage) told me about batteries with no fluid thus making them leak proof, it was my turn for my mouth to fall agape. I though not much research and development had gone into energy storing.

He spoke about the usage of glass mat technology in battery manufacturing which I definitely could not comprehend.

In the end, I vowed not to talk to any engineer.

Don't throw away your newspapers.



First, I will tell you about electronic ink and then tell you why you need not throw away your used news papers.

I am sure you are aware of e-paper-the daily news papers you receive in your mail box are also available in digital form in your computer. Unlike a conventional flat panel display, which uses a backlight to illuminate its pixels, electronic paper reflects light like ordinary paper and is capable of holding text and images indefinitely without drawing electricity, while allowing the image to be changed later.

The e-ink rearranges itself each morning to form new headlines. Or maybe you've just finished pouring over a new best seller. No need to pass it along to a friend; the print can morph Harry Potter style into a new book.

Sound unreal? It is the world of electronic ink.

The e-ink, in its appearance is similar to regular ink but there is an uniqueness about it. It is made up of many tiny capsules, these capsules are filled with ink, and the ink contains white particles that have a negative charge. These three properties allow an electronic ink display to be changed on demand.

E ink can be used on many of the same surfaces as regular ink

Faith unlocks the door; your fingers too.

I could not care less for newspaper reports of house breaks in suburban areas. This doesn’t imply that I live in the heart of city; I live far away from it.

Of course I have some valuables in my house that are obviously more valuable for intruders.

No, I have not insured my properties.

I have not posted any security at my house.

My house is not wired to any fancy home security gadgets.

Still, I am not afraid to go on a long holiday locking my house behind simply because my house is break proof; it has keyless lock. Oh, I know I am building up the suspense. I enjoy it more when I break the suspense.

My house door can be unlocked only by my finger. This keyless lock technology is based on ‘Biometrics’ that is used in authentication purposes by finger prints, eye contacts and even voice recognition.

BTW, my house’s main door is not fitted with biometric lock but my bedroom cum office where the most valuable property is the DATA in my computer.

Please have a look at this keyless lock that looks very sturdy and safe. Again, it recognizes only your finger prints.

Here is another ‘never-seen-before’ type of lock that has no keys. It is called ‘Keyless Mortise Door Lock’ and it costs only $100

Can use IR mobile as a modem.

Using your infra red Nokia phone to use as a modem to connect to the Internet requires some technical guidance. And this will be very handy when you travel carrying your laptop without any broadband Internet connection.

This technology uses the ancient dial-up connection and yes, it will be slow but still useful when you have no other way to go online.

To make new Internet connection follow this steps:

1. Select Connect to the Internet. Click Next.

2. Select Set up my connection manually. Click Next.

3. Select Connect using a dial-up modem. Click Next.

4. Check the option Infrared Modem. Click Next.

5. Give a name to your ISP. Click Next.

Speak from your mobile while sailing.

I was on the dot for my appointment with a BPO provider. I was there to inquire about the possibility of renewing a contract for my online contact. The original contract with a Swedish company was about to expire.
The BPO company is housed in a high rise building in a sprawling campus consisting of more than 15 giant towers.
I sat facing an imposing man who showed indifference to me. May be my diminutive stature didn’t seem to go well with him. But as the discussion progressed, he became more attentive to me. My in depth knowledge about the topic must have made him to look at me with some respect.
In between our meeting, he kept receiving intermittent calls on his mobile. Suddenly I realized that I am a witness to a technology that was new to me. I am aware that cell phones either go silent or they are reluctant to give uninterrupted signal in high rise buildings or wherever there is a concrete jungle.
I took up the courage to ask him how come he is able to talk freely on his mobile phone when sitting in his office on 7th floor. He was suddenly pleased. With a look of pride, he informed me that cell phone repeaters are installed in all the buildings in the campus.
He explained that a cell phone repeater works like an amplifier that picks up the radio signal from the base tower and amplifies the signal in such a way that signal is clear even inside the building or deep underground.
“Does it mean that the battery power lasts longer because it need not have to strain itself to pick up the radio signal”?-I asked.
His face lit up with appreciation and affirmed my guess.
