An Englishman, a Scots man, and an Irish man are sentenced to 100...

An Englishman, a Scots man, and an Irish man are sentenced to 100 lashes.

The judge was in a benevolent mood though and offered them each a request that maybe would make it easier on them.

The Scottish man asked for a pillow to be strapped to his back, but it had worn away after 50 lashes and he suffered for the remaining 50.

The Englishman being smart asked for 2 pillows, and he didn't feel any of the lashes on his back.

Before the Irishman was asked, the judge said "I love Ireland, it has given us the greatest music, poets, writers and art - because of this you get 2 requests"

The Irishman thought and said "firstly I'd like 200 lashes, and second of all strap the Englishman to my back"

World's biggest battery

In 2003, the world's biggest battery was connected to provide emergency power to Fairbanks, Alaska's second-largest city. Without power lines between Alaska and the rest of the U.S., the state is an "electrical island." Worse, tough environmental conditions cause a total city blackout every two or three years. The $35 million rechargable battery contains 13,760 large nickel-cadmium cells that weigh a total of 1,300 tonnes and cover 2,000 square metres, an area greater than a sports field. The battery can provide 40 megawatts of power, enough for around 12,000 people, for up to seven minutes, while diesel backup generators are started. This will be an important safeguard, where winter temperatures can drop as low as -51ºC.
