Mega-Projects of the World

If you're interested in mega-scale projects, I had written about the "Palm Jebel Ali" and the "Palm Jumeirah" islands earlier (And then man built an island...) These are the two huge man-made islands built in Saudi Arabia.

Today, I came across Tokyo's G-Cans project.

"The G-Cans Project is a massive project, begun 12 years ago, to build infrastructure for preventing overflow of the major rivers and waterways spidering the city (A serious problem for Tokyo during rainy-season and typhoon season). The underground waterway is the largest in the world and sports five 32m diameter, 65m deep concrete containment silos which are connected by 64 kilometers of tunnel sitting 50 meters beneath the surface.

The whole system is powered by 14000 horsepower turbines which can pump 200 tons of water a second into the large outlying Edogawa river."

The whole site is in Japanese, but the pictures are great.

Check out the photo gallery. There is a flash animation here.
