Count down the technological leaps in six landmark domes including Rome's Pantheon and Florence's Cathedral, that allowed this, the world's largest spanning dome, to be built.

Uncover the technological leaps that allowed the world's biggest cruise ship - the Independence of the Seas - to be developed. The ship cost US$800 million to build, carries her passengers in unrivalled luxury and is manned by a crew of 1,360 who occupy a vast behind-the-scenes world of control rooms, kitchens and engine spaces. Longer than 5 jumbo jets and weighing more than 80,000 family cars, explore how this gargantuan ship was made possible through a series of six historic breakthroughs on liners such as the SS Great Britain and RMS Queen Mary, that allowed engineers to build ever-larger ships.

Filter through the technological leaps forward that have allowed the world's largest hydroelectric dam - the Three Gorges Dam in China - to be built. The Dam harnesses the power of China's great Yangtze River. It is over two kilometres long, towers over 60 storeys high and creates a reservoir 600 kilometres in length. On completion the scheme will be able to generate 22,500 megawatts of power - enough to supply electricity to 60 million people. At its peak, over 25,000 men and women were working round the clock to make what was once Chairman Mao's dream a reality. Explore how this immense project was made possible through a series of breakthroughs on six landmark dams - including the Hoover Dam in America. Each features a major technological innovation that allowed engineers to create bigger dams to generate ever more hydroelectric power.

Explore the giant technological leaps forward that have enabled the world's biggest space station to be built. The International Space Station orbits 350 kilometres above our heads, hurtling around the Earth at almost 30,000 kilometres an hour. It is one of the greatest engineering feats of all time. Its crew performs vital experiments that will one day allow humans to live permanently in space. A test bed for future missions deeper into space, the space station could enable future generations to journey throughout the Solar System or even live on Mars. Five landmark space stations contributed innovations to allow engineers to build bigger, making it possible to explore the wonders of space travel and push the boundaries of science ever farther.

Uncover the technological leaps forward that have enabled the world's largest observation wheel - the Singapore Flyer - to be built.
