wohahaha..
here comes the next posting about an unbelievable structure.. that's why i namd it MEGASTRUCTURE
this is the 4th Megastructure... it is the biggest swimming pool...
It is more than 1,000 yards long, covers 20 acres, has a 115-foot deep end, and holds 66 million gallons of water.
The Guinness Book of Records has named the vast pool beside the sea in Chile as the biggest in the world.
But if you fancy splashing out on one of your own -- and you have the space to accommodate it -- then beware: this one took five years to build, cost nearly 1 billion, and the annual maintenance bill will be 2 million.
The man-made saltwater lagoon has been attracting huge crowds to the San Alfonso del Mar resort at Algarrobo, on Chile 's southern coast, since it opened last month.
Its turquoise waters are so crystal clear that you can see the bottom even in the deep end.
It dwarfs the world's second biggest pool, the Orthlieb -- nicknamed the Big Splash -- in Morocco , which is a mere 150 yards long and 100 yards wide. An Olympic size pool measures some 50 yards by 25 yards.
Chile's monster pool uses a computer-controlled suction and filtration system to keep fresh seawater in permanent circulation, drawing it in from the ocean at one end and pumping it out at the other.
The sun warms the water to 26c, nine degrees warmer than the adjoining sea.
Chilean biochemist Fernando Fischmann, whose Crystal Lagoons Corporation designed the pool, said advanced engineering meant his company could build "an impressive artificial paradise" even in inhospitable areas. It uses hardly any chemicals.
"As long as we have access to unlimited seawater, we can make it work, and it causes no damage to the ocean."
