Witness the Bahrain World Trade Center. Two 50-story glass "sails" rise over 240 meters into the sky along the shores of the Persian (Arabian) Gulf. This unique architectural marvel is powered in part by a revolutionary new means for a building this size - wind. It's the world's first large-scale integration of wind turbines into a skyscraper. Three massive turbines will supply clean power to the buildings. In this hour, we explore the science behind the concept and discover how engineers and construction crews attempt to tackle this audacious project. In an oil-rich region of the world, the team transforms the vision to reality and looks to the future, committed to a renewable energy source of mega proportions.

The Orange Bowl, home to the Miami Dolphins for 21 seasons and host of five Super Bowls is about to be demolished. It’s a monster breakdown job, with a monster deadline: in just four months, a demolition team needs to clear over a quarter million feet of stadium to prepare for a new stadium. Not only is there a tight timetable, everything must be salvaged or recycled. But before the team can break down the stadium, they have to save parts of it. After a memorabilia company combs the bowl for collectibles and auctions off what they salvage, it’s finally time for the demolitionists to get their hands on the bowl. 50,000 left over orange seats, nearly 100,000 square feet of turf, and eight ten-ton stadium light towers are recycled or resold, freeing the team to take down the stadium itself. Using a combination of wrecking balls and mega machines, they cut, pull and pummel this historic structure until it’s nothing more than rubble. The iconic Orange Bowl, is about to be history.

Perched 4,000 feet above the Colorado River on the very edge of the Grand Canyon is one of the most recent and innovative engineering marvels of our time. The Grand Canyon Skywalk, opened to the public in March 2007, is an engineering masterpiece united with natural wonder. It is the first ever cantilever designed glass bridge. Constructed in a horseshoe shape, visitors are given the chance to walk out over the edge of the canyon and look straight down. It's about 4,000 feet above the canyon, which is higher than any of the world's largest buildings and extends 70 feet from the edge. Take a closer look at the Skywalk's design, construction and the people that made it a reality.

In the extreme Russian north a team of engineers are ready to dismantle a Typhoon-class submarine – the world's largest nuclear submarine. In its heyday, this monster sub was a terrifying weapon of war. It prowled the oceans of the world armed with 20 deadly nuclear missiles. Now that the Cold War is over, the Typhoon is ready for demolition. But dismantling a submarine with two nuclear reactors is a risky mission. It will take the team over a year to remove the radioactive nuclear fuel, move the submarine into the dry dock and cut its hull into pieces small enough for recycling.

Three teams of engineers are locked in a race to harness what may be the most powerful form of green energy: swift tidal currents and battering waves, the power of the oceans. Each team believes it can solve a portion of the world's energy needs. They're testing three different machines designed to be placed in the water and convert oceanic energy into electricity. But getting the machine from the design stage to implementation is a difficult challenge and now each team prepares to install their systems and turn them on for the first time. If they succeed, they could radically change the way we power our planet.

The only purpose-built "flying crane" in existence, the Air-Crane heavy lift-helicopter is the most powerful helicopter workhorse in the world. It does extra-heavy, brute-force work with surgical precision thanks to its ability to keep its hanging load from twisting or swinging while aloft. It's also the only helicopter in the world with an aft-facing pilot seat to allow the payload to be strategically placed.

This installment follows the demolition of a 40-year-old rocket launch tower at Cape Canaveral. This tough, 90m high structure represents a massive logistical challenge for a family of demolition experts. Up to a third of the building’s entire weight must be stripped out before the tower can be imploded. Workers must brave high winds at great heights to ensure charges are planted correctly.

For over 40 years the Big Red Box at Jackson Hole, Wyoming, carried skiers, hikers, paragliders and sightseers up to the 3,400-metre summit of Rendezvous Mountain. But nothing lasts forever, so when cable inspector Norm Duke found evidence of stress fractures inside the aging steel track cables, there was no choice but to tear down and replace Jackson's iconic aerial tram. At a cost of US$31 million, this two year construction project is a top-to-bottom, state-of-the-art replacement. It will operate in 120 kph winds and minus 30°C temperatures, all with the quiet precision of a giant Swiss watch. Construction crews battle a record-breaking snowfall, zero visibility, high winds and impassable mud-slick mountain roads to build its five towers and two terminals, and string more than ten miles of heavy steel cable as they risk their lives in a battle to finish before winter closes in.
