WIRELESS POWER TRANSMISSION
The days of wires powering electronic devices could soon be at an end, with the development of a new system that will allow laptops, mobile phones and televisions to be left unplugged in the home while being recharged.
The new technology exploits a recent breakthrough in physics, according to the US company WiTricity. It has shown that it can send electricity “wirelessly” through the air and can switch on a light bulb or keep a computer running.

DOES TALLER PEOPLE EARN MORE ?
It finds that taller people, particularly men, earn more money - with every five centimeters of height being worth about $950 per annum.
“Our estimates suggest that if the average man of about 178 centimetres gains an additional 5 centimetres in height, he would be able to earn an extra $950 per year - which is approximately equal to the wage gain from one extra year of labour market experience”, explained co-author Professor Andrew Leigh.
The study also finds that, while there are wage returns to height in Australia, there are no systematic wage penalties to having a higher body mass index (BMI).
Professor Leigh added, “We began the project with a primary interest in whether overweight people were paid less, but eventually realised that the most interesting thing in the data is the relationship height and wages.”

ATM THIEFS-''be carefull"
WHEN A THIEF FORCES YOU TO TAKE MONEY FROM THE ATM, DO NOT ARGUE OR RESIST,
YOU MIGHT NOT KNOW WHAT HE OR SHE MIGHT DO TO YOU. WHAT YOU SHOULD DO IS TO
PUNCH YOUR PIN IN THE REVERSE, I..E IF YOUR PIN IS 1254, YOU PUNCH 4521.
THE MOMENT YOU PUNCH IN THE REVERSE, THE MONEY WILL COME OUT BUT WILL BE
STUCK INTO THE MACHINE HALF WAY OUT AND IT WILL ALERT THE POLICE WITHOUT THE NOTICE OF THE THIEF.
EVERY ATM HAS IT; IT IS SPECIALLY MADE TO SIGNIFY DANGER AND HELP. NOT EVERYONE IS AWARE OF THIS.
SO BE CAREFUL.

LG ELECTRONICS INTRODUCES 2 NEW "FULL LED" LCD TVS
LG’s newest ultra-slim full LED LCD TVs employ patented technology that helps keep the overall chassis thickness down to just 24.8mm. This proprietary technology allows the LEDs to be spread-out horizontally and minimizes the distance between the LEDs and the screen. Another innovation offered for the first time in the new LED LCD TV is the enhanced wireless feature which eliminates the need for image compression. Content can be sent from DVD players, game consoles or home-theater units wirelessly without any degradation.
LG’s ultra-slim full LED LCD TV is priced at around KRW 7 million (approximately US$ 5,500) for the 55LH93 and around KRW 7.6 million (approximately US$ 5,900) for the 55LH95 model which will be launched in July 2009.
LG plans to aggressively expand the LED LCD TV business and is aiming for three to four million unit sales next year. Three different models of full LED LCD TVs will be offered to suit different market segments. The ultra-slim model will be positioned as the premium product with additional products in this category being announced later this year. The company will unveil less expensive 42-inch and 47-inch full LED LCD TVs by the end of the year without the ultra-slim feature.
LG is forecasting that the global LED LCD TV market will grow to 30 million units by next year and to 68 million by 2011, up from 3.1 million this year. LG is aiming to become the world’s second biggest seller of LCD TVs and predicts that the proportion of LCD TVs that feature LED technology will also grow from 2.6 percent this year to 20 percent next year and to 40 percent by 2011.
