Nakheel Tallest Tower Then Burj Tower Dubai
It seems like the Burj Dubai will be dethroned from the “world’s tallest tower” position as (also) in Dubai will be built a one kilometer skyscraper. The tower was designed by Woods Bagot Australian architect and it will be built by Nakheel, the same developer which has built those fancy state-of-the-art man-made islands in Dubai. The skyscraper will be called Nakheel Tower and as a bonus, there will also be built world’s first inner city harbor. 200-storey tower Nakheel Tower will be built by 2020.

Competing MTX, Worlds Biggest Subwoofer
Royal Device has on its own developped and built in Italy the biggest subwoofer of the world for an Audio/Video room that can be also considered as the greatest AUDIO ROOM for private music listening of the world. The Royal Device audio room belongs to Roberto - the audio designer who made it.
The audio reproduction is focused on the speakers output capability more than electric power output of the amplifiers with no need of KWatts power supply lines, releasing more than 110 dB/1W/1 meter sensitivity starting from below 10 Hz focused on the listening position.
SUBWOOFER horns are built underneath the floor in a cavity of 1 meter deep. Each horn is driven by 8 x 18" (47 cm) woofers. A total of 16 woofers.
Each horn is 9.5 meters long and has a floor mouth area of 2.2 square meters and reproduce starting from 10 Hertz FULL POWER. The real mouth area IS NOT the one on the floor. The real mouth have to be considered together with the side vertical frontal panels. The total horn is calculated onto the listening point considering the side walls and the ceiling loadings. This reduces the floor mouth that is not in open air.
The SUBWOOFER efficiency is 120dB/ 1 Watt/1 meter. So the need of external regulation to adapt to the remaining audio system. The total electrical capability of the 16 x 48 cm woofers is about 400 W peak power per woofer that means about 400 x 16 = 6400 W peak total (practically uselss). Each woofer features a 100 mm coil. The real maximum power fed to both subhorn measured with an oscilloscope at the highest musical peak was 6 watts per channel when a pair of tube amps were used to drive the 16 LAuras, while up to date the electric power can reach 60 watts per channel using the 4 x 50watts/ch BLU EYES amps. In this conditions, peak levels are much higher and undistorted than any live concert at all. Walls and ceiling seems to fall down, but fortunately don't. The sound pressure is concentrated at the listening point and stopped by a 2 meters high woolglass anechoic wall on the back of the listening position. We should remember that the total diaphragm surface of the woofers is 2.89 square meters (8.67 square feet) and with the drivers horn loaded (not direct radiating), distortion at 60 watts is practically negligible. If for instance the real maximum rated power (6400 watt) would be used the pressure level would reach 160 dB, but I wonder who could survive. Not even the house built in steel & concrete maybe would stand up.

Dutch Set World Domino Record
A new world record for the number of dominoes toppled in one go was set in the Netherlands on Friday night, when according to event organisers, 4,345,027 dominoes fell during a two-hour TV show.
Smallest Snowman In Cristmas Season
You're looking at the tiniest snowman ever built. Well, it looks like a snowman, but this minuscule model about a fifth the width of a human hair is not made out of snow. It's constructed of two tiny tin beads that are usually used to calibrate an electron microscope, and welded together with platinum.
It's built by David Cox, a nanotech expert at the Quantum Detection Group of Britain's National Physical Laboratory. He's accustomed to working with such astonishingly small objects, and used his nano-particle manipulation tools to demonstrate the astonishing accuracy of his work.
He bathed the snowman in blue light to give us this entertaining, snow-blown image. The remarkable flourish of his smiling snowman is its little happy face, carved into the top orb using a focused ion beam. That's no small feat.

Largest Bikini-Clad Girls Parade
Hundreds of bikini-clad girls took to the streets of Johannesburg to set a new Guinness record for the World’s Largest Bikini Parade, defeating the previous record, set by participants in Las Vegas in May.
In total, 287 scantily-clad girls walked 1,690 meters on Melrose Arch Boulevard. Participants hoped that, in addition to setting a world record, the parade would raise awareness of breast cancer, a condition affecting one in every thirty South-African women. The event took place on November 9th, 2009.
