What's behind Nokia's ClearBlack display technology?

Nokia's ClearBlack Display technology has been announced in September 2010, and Nokia is using it in several phones (including the Lumia 900, Lumia 800 and older Symbian models such as the X7 and E7). We know that it includes polarizing filters to block incoming light. Today however Nokia finally revealed how it actually works: A CBD filter includes both a linear polariser and retardation layers between the surface of your phone and the display. When light hits your screen, this is what happens: It hits the linear polariser, this vertically polarises the light. (Polarising means – roughly – aligning the wave vibration in a particular direction). Then it hits the circular polariser retardation layer. This converts the light...

Australian farmer revolutionizes water-turbine technology

The Sundermann turbine "T3" prototype was tested in Hervey Bay, Queensland.MELBOURNE — Fred Sundermann, an Australian farmer with a long history in design and innovations, has developed a bi-directionally low-head water turbine designed to maximize operational efficiency in slow water flows. Turbines have been around for more than a century, but Sundermann Water Power (SWP) Limited (the business backing the technology) claims that the Sundermann Turbine (S-Turbine) is the most efficient in harnessing the power of water.“The problem today is that all existing lo-tech turbine systems throughout the world are inefficient as such whereby the water that hits the blade flows either passes through or around the blade, thus making them...

The Curse of Child Servitude

A girl not more than ten years of age trying to lift quite a healthy kid up, who I am sure was heavier than her, to a ride. She loses her balance in an effort to do so. This was a scene I got to see at a famous fast food restaurant play area. Yes! That little girl was a servant to a big happy family. The parents sit alone and dine in while the servants babysit the mischievous kids. Babysitting of course includes feeding them, taking full care of them that they don’t get lost and also bearing with all their stubbornness. Getting help of a servant is not bad at all, it’s just you should at least consider the age of a person before you hire him/her. How can you expect a kid, who herself/himself is not able to carry her/his own burden, to...

England need second-highest run chase in Test history for unlikely win over Pak

Azhar Ali scored a dogged 157 to push Pakistan's lead to 323 in the Dubai Test © Associated Press England at last saw the back of Azhar Ali, but still need to pull off the second-highest run chase in their Test history to avoid a 3-0 whitewash against Pakistan. Azhar's painstaking career-best 157 spanned six sessions and almost nine hours, before the number three was ninth out in Pakistan's 365 all out on the third evening at the Dubai International Cricket Stadium. England were therefore left with more than six and a half sessions to make 324, on a wearing pitch which had already helped spinners Monty Panesar (five for 124) and Graeme Swann share eight wickets. They made an acceptable start to their mission improbable, openers...
