#1 - George Washington Carver Tech

Season 12 - Episode 8 - Aired 2/15/2005

One of the 20th century's greatest scientists, George Washington Carver's influence is still felt. Rising from slavery to become one of the world's most respected and honored men, he devoted his life to understanding nature and the many uses for the simplest of plant life. His scientific research in the late 1800s produced agricultural innovations like crop rotation and composting. Part of the "chemurgist" movement that changed the rural economy, he found ingenious applications for the peanut, soybean, and sweet potato. At Tuskegee Institute, Dr. Carver invented more than 300 uses for the peanut, while convincing poor farmers to rotate cotton crops with things that would add nutrients to the soil. A visionary, Carver shared his knowledge free of charge, happy in his Tuskegee laboratory where he could use his gifts to help others.

Season 12 - Episode 21 - Aired 4/27/2005

Join us on two treacherous trips as we follow two separate structural moving families in their struggles to relocate and save a 100-year-old homestead and an 1890 Queen Anne Victorian house. In Colorado, a father and son have to fight fierce weather and the fragility of a purported haunted log cabin and decaying barn to move them two miles across a rugged mountainside. In Illinois, three generations of movers are pushed to their limit when they are hired to transport a 180-ton monster house across town. Will these historic homes reach their final resting places in one piece and find peace?

#5 - Desert Tech

Season 12 - Episode 10 - Aired 2/23/2005

It's hot, dry, deadly, and hard to ignore with close to 40% of Earth classified as desert. But in this scorching hour, the desert turns from barren wasteland into an environment rich with hope. In the Middle East, desalination of seawater now fills water needs. Americans have created booming desert communities like Las Vegas, where the Hoover Dam produces hydroelectric power and manmade Lake Mead supplies water. Native Americans farmed the desert on a small scale, but 20th-century technology begot greater opportunity. Once desolate areas of California and Mexico now grow agriculture due to irrigation, and the desert's abundant sunshine allows solar-energy and wind-power production. And in the future, desert technology may enable colonization of planets like Mars. We also take a look at how refrigeration and air conditioning have made life in desert communities tolerable, and examine the latest in survival gear and equipment.

#6 - Nature Tech: Lightning

Modern Marvels examines the incredible phenomenon we know as lightning.

#7 - The Cape Cod Canal

Season 12 - Episode 29 - Aired 6/15/2005

In a battle against the ferocious Atlantic or safe passage through waters where ships wrecked and lives were lost, it was an engineering feat that many believed impossible. This is the story of the Cape Cod Canal and the men who braved the natural elements and the Great Depression by venturing into new engineering territory. In 1909 excavation began on what would become one of the greatest success stories of our time. The evolution of the Cape Cod Canal into what it is today--a major commerce and recreational route of the Intracoastal Waterway--is a tale of determination, ingenuity, and the American spirit. Through historical photographs and expert interviews, the Canal's story unfolds, and while traveling along on an Army Corps of Engineers Patrol Boat and Coast Guard vessel we see firsthand what happens on the Canal on a daily basis. And we meet the people who make the Canal and its bridges functional and safe, keeping the legacy of the early engineers alive.

#8 - Walt Disney World

Season 12 - Episode 66 - Aired 12/25/2005

It is a magical place, full of animated storybook characters, majestic castles, thrilling rides, and colorful parades. For over thirty-five years, Walt Disney World has been welcoming and entertaining kids of all ages, cultures, and backgrounds. The world-famous Orlando theme park is not only the most visited in the world, it’s also the most technologically advanced. From a network of underground tunnels connecting various regions of the park, to the space-age propulsion technology of linear synchronous motors, the Disney dynasty has been on the leading edge of theme park innovation since the opening of Disneyland, its first park, in 1955. With soaring castles, sleek monorails, and lifelike animatronics, THE HISTORY CHANNEL takes a behind-the-scenes look at the ingenious industry and incredible engineering feats that went into building the renowned 27,000 acre Disney World complex.

#9 - The Arch

Season 12 - Episode 3 - Aired 1/12/2005

Join us as we explore the vast and varied world of the arch, one of the strongest and most versatile structures made by man. Deceptively simple, an arch can support tremendous weight because its structure is compressed by pressure, and it provides a much more spacious opening than its predecessor--post and lintel construction. Although ancient Egyptians and Greeks experimented with the arch, the Romans perfected it. Medieval Arabs incorporated it into stunning mosque architecture, soon followed by Europe's great medieval churches. In the 19th and 20th centuries, the steel arch became a favorite of architects and structural engineers. Dam builders employed it horizontally, using the water behind the dam to provide the pressure to compress it. And tomorrow, the arch will continue to serve mankind in every form--from nanotechnology to domes on Mars and beyond.

#10 - Punishment

Season 12 - Episode 22 - Aired 7/16/2012

#11 - World's Biggest Machines (3)

Season 12 - Episode 5 - Aired 1/26/2005

Giant robots on the factory floor and in outer space. A floating fortress that's home to 6,000 military personnel, which is almost as long as the Empire State Building is tall. And a diesel engine with 108,000 horsepower. (You read that right.) These giants must be seen to be believed! In this episode, we travel over land and sea to find these and more of the biggest, baddest, most audacious feats of engineering in the world.

#12 - Glue

Season 12 - Episode 24 - Aired 5/18/2005

It's Super! It's Krazy! And it can be found in everything from carpet to computers, books to boats, shoes to the Space Shuttle. It's even used in surgery! Without it, our material world would simply fall apart. In this episode, we'll visit the stuck-up, tacky world of glue. Glue's sticky trajectory spans human history and we'll cover it all--from Neolithic cave dwellers who used animal glue to decorate ceremonial skulls to modern everyday glues and their uses, including Elmer's glue, 3M's masking and Scotch tape, and the super glues. Remember the Krazy Glue commercial in which a man held himself suspended from a hard hat that had just been glued to a beam? Well, that 1970s vintage ad understates the power of glue. With the help of a crane, we're going to hoist a 6,000-pound pickup truck off the ground by a steel joint that's been bonded with glue!

#13 - The B-2 Stealth Bomber

Season 12 - Episode 45 - Aired 8/26/2005

In any battle, the key to victory is the ability to strike the enemy without them knowing what hit them. Within the US arsenal one such weapon can go into harm's way, deliver 40,000 pounds of either conventional or nuclear bombs, and slip away unobserved--the B-2 Stealth Bomber. With its origins in single-wing experimentation in Germany in the 1930s, the B-2 was developed under a cloak of secrecy. But when that cloak was lifted, the world was awed by what stood before them. Able to fly over 6,000 miles without refueling, it can reach whatever target the US military wants to attack and deliver its awesome array of laser-guided weapons with pinpoint accuracy. Using state-of-the-art technology, including over 130 onboard computers, and shrouded by a mantle of stealth, it's undetectable by any radar.

#14 - The World's Fastest

Season 12 - Episode 44 - Aired 8/24/2005

Perhaps no field has experienced this revolution in velocity more acutely than transportation. We look at five blazingly fast technological marvels that have pushed the speed limits to the very edge, each with its own unique and dramatic history: the world's fastest production car (Sweden's Koenigsegg CCR); the world's fastest train (the Maglev in Shanghai); the world's fastest boat (The Spirit of Australia); the world's fastest roller coaster (the Kingda Ka) and the fastest thing on earth (the Holloman High Speed Test Track), used to test highly sensitive equipment for many branches of the government and commercial clients.

#15 - Deadliest Weapons

Season 12 - Episode 17 - Aired 3/16/2005

In this fiery hour, we profile five of the world's deadliest weapons, focusing on the inventors, battles, and dark technology behind their lethality. Beginning with the deadliest bomb ever created, the Tsar Bomba--a 50-megaton nuclear bomb--we move on to the deadliest weapons ever used on people, the atomic bombs exploded over Hiroshima and Nagasaki in August 1945. During WWI, the machine gun led to the deaths of over 8-million, and in WWII, the use of incendiary bombs killed hundreds of thousands of people. Another deadly invention of WWII was the proximity fuse, or VT fuse, that allowed artillery to detonate within a predetermined range of an enemy target. Finally, we examine VX nerve gas--a deadly chemical agent used twice by Saddam Hussein with devastating results--and visit Edgewood Chemical BioCenter, where suspicious items in the current war in Iraq are examined for traces of VX.

#16 - Lube Job

Season 12 - Episode 41 - Aired 8/10/2005

From chariot wheels of ancient Egypt to hard disks in a computer to the wheels on a Mars rover, machinery can't function without lubricants. And in today's technology, there are a mind-boggling number of friction points that must be lubed, and a staggering number of lubricants-- petroleum motor oils that keep car engines from burning up, synthetic greases that stay put in the zero gravity of space, and solid coatings that prevent eggs from sticking to a pan. We'll see how this marvel of chemistry works and how it's used. Peering into the future, we'll behold a power generator that employs air as a lubricant, trains using magnetic levitation, which eliminates any need for lubrication, and bio-engineered vegetable oils that promise to take humanity back to one of its very first lubricants. From helping medieval windmills spin, to allowing robotic arms on planetary rovers to move, lubricants are crucial to the advance of technology and literally keep the wheels of progress turning.

#17 - Firefighting! Extreme Conditions

Season 12 - Episode 9 - Aired 2/15/2005

This episode of Modern Marvels examines the most extreme raging fires and the firefighters who tame them. The program features interviews with a World War II firefighter who helped contain the London’s blitz fire. We also meet “Hell Fighters” who fight raging oil well fires, and “smoke jumpers” who parachute into forest fires. Firefighting: Extreme Conditions also takes a look at how NASA guards against the very real risk of a fire aboard a space vessel.

#18 - The F-117 Nighthawk

Season 12 - Episode 54 - Aired 9/22/2005

The project was surrounded by secrecy and dogged by controversy from the very beginning. Starting in the late '70s, engineers at Lockheed's legendary "Skunkworks" developed a revolutionary new fighter that was destined to transform aerial combat forever. Little more than a decade later, the F-117 NIGHTHAWK STEALTH fighter saw combat for the first time in Panama.

#19 - Route 66

Season 12 - Episode 43 - Aired 8/24/2005

Route 66, encompassing eight states from Illinois to California and 2,400 miles, represented an American myth--that something better lay over the rainbow. Route 66 began in the early 20th century when a confluence of technologies--automotive, steel construction, and concrete paving--merged with population explosion, westward migration, and prosperity after WWI. The federal government responded with highway bills that converted existing roadways into an interstate called Route 66. Later, WWII highlighted the need for a strategic system similar to Germany's Autobahn--wider, safer, and more advanced. As federal and state governments worked on a superhighway, millions sought "their kicks on Route 66." By 1985, the abandoned roadway no longer "officially" existed, yet, it remains a destination for nostalgic travelers wishing to recapture a simpler, more adventurous era.

#20 - Secret Luftwaffe Aircraft of WWII

Season 12 - Episode 42 - Aired 8/17/2005

German military aircraft designs were decades ahead of their Allied counterparts. To insure Luftwaffe superiority, their designers tested advanced concepts including swept-wing and vertical take-off aircraft and stealth bombers. Using computer-generated images and archival footage, we trace development of Hitler's airborne arsenal.

Buckle-up for safety as we race into the near future--where fantasy becomes fact. There have always been visionaries, futurists, and dreamers predicting the world of tomorrow--flying cars, space-station colonies, and android personal assistants. But time has proven the fallacy of many of their predictions. So what future technology can we realistically expect? With the help of 3D animation, we present some pretty far-out predictions and take you to various research labs to see working prototypes of these technologies in their infancy. Join us on a rollicking ride through the entertainment room, down the road, over the battlefield, through the mind, out in space, and into the future, where science fiction becomes science fact.

#24 - Engineering Disasters (17)

Season 12 - Episode 58 - Aired 11/2/2005

It's another chapter of complex, deadly and controversial engineering failures, using 3-D animation, forensic engineering experts, and footage of the actual disasters to understand what went wrong, and how disaster has led to improvement. In Sun Valley, California, weeks of record rain turn a crack in the middle of a street into a 200-foot long sinkhole. Months later, rain led to the Laguna Beach, California landslide, which destroyed 11 homes and caused millions in damage. On May 23, 2004, four people were killed when the roof of the new Terminal 2E at Charles de Gaulle International Airport in Paris collapses. Other disasters: the 1931 crash of Fokker F-10 passenger airplane with coach Knute Rockne aboard; the sinking of the coal ship Marine Electric off the coast of Virginia; and the blinding reflection of the new Walt Disney Concert Hall in Los Angeles.
