Modern Marvels: Nature Tech: Tsunamis
Overview
Among the most mysterious disasters, tsunamis–Japanese for “harbor waves”–claimed over 50,000 lives in the 20th century! Generated by offshore earthquakes, volcanic eruptions, and landslides, these giant water walls result from large-scale displacement of seabed sediment. Rolling rapidly over the ocean floor, a tsunami rises to rapturous heights when it hits land. Scientists in Japan, Hawaii, Oregon, Washington, and California show the latest technology used to predict these killer waves.

Episode 34: Engineering Disasters 4
Engineering disasters can result in personal tragedy, national humiliation, and economic ruin. But buried within their wreckage lie lessons that point the way to a safer future. The fire at the Las Vegas MGM Grand Hotel, the collapse of Seattle’s Lacey V. Murrow Floating Bridge, the car that spurred creation of the National Highway Transportation Safety Administration, and the flaw that grounded the first commercial jet are among the engineering disasters that led to improvements in design and safety.
Episode 36: Logging Tech
When Paul Bunyan cried "Timber!", he never foresaw today's cutting-edge, controversial industry that feeds a ravenous, lumber-crazy world–a world striving to protect nature while devouring it. Come into the woods to see how he-men and hi-tech combine forces to topple 4-billion trees annually; journey to 19th-century America, when lumberjacks cut a legend as large as the timber they felled; and travel with a tree from stump to sawmill and learn its non-wood uses–from aspirin to film to toothpaste!

Episode 37: Breaking the Sound Barrier
For decades, the sound barrier loomed as an impenetrable wall against manned flight that buffeted planes with shock waves as they approached the speed of sound. Scientists thought the barrier couldn’t be breached–until the development of jet technology and rocket fuel at the end of WWII. This is the dramatic story, told through the eyes of many who were there, of the work leading up to October 10, 1947, when 24-year-old test pilot Chuck Yeager smashed through the sound barrier in a Bell EM XS-1 /EM aircraft.

Episode 38: Car Crashes
In the mid-1960s, the US lost an average of 55,000 people yearly to car crashes. Since then, the number of cars on the road has doubled, but fatalities have decreased by nearly a third. The dramatic reduction is the culmination of research and development that led to safer roads and cars and quicker emergency response. But car-crash technology’s future involves removal of its biggest threat–human drivers! Find out if computers and radar can prevent everything from fender-benders to pile-ups.
Episode 31: Dangerous Cargo
Toxic traffic is everywhere! An average of 800,000 shipments of hazardous materials hit our highways and railways daily. From Wild West wooden crates filled with explosives to HAZMAT containers of nuclear waste, we shadow dangerous cargo. We ride shotgun on a hazardous material shipment that's tracked by satellites; hunt down the hush-hush "ghost fleet"–trucks carrying classified government materials; and board a Con-Air flight moving another kind of nasty stuff–dangerous felons!
Episode 39: Sandhogs
Sandhogs work hundreds of feet down, where it is dark, damp, and dangerous, challenging nature’s awesome forces to drive tunnels through solid rock and sinking mud. They drill and blast, bore, mine, and muck. The painstaking process continues for days and yards, months and miles. Tragically, many sandhogs have been killed or injured in the process, but ultimately theirs is a story of triumph and survival. Join us as we review their impressive achievements and history.
Episode 30: 4x4
In this full immersion journey through the world of maximum off-roading, learn what it’s like to blow the carbon out of your system as we trace the history of the four-wheel drive vehicle. From the annual Baja 1000-mile race to the Paris-to-Dakar rally, off-roading has become an international sport for motorized thrill seekers. Drive along in your Jeep, dune buggy, Hummer, or SUV for this high-adrenaline, fun-filled romp as we see why 4x4s go where no one has gone before!
Episode 40: Convertibles
Topless, unobstructed–the convertible completely transforms the driving experience and unlike any other car, sets the driver free. During this face-paced hour, experts highlight the history of the world’s most dynamic car design and the essential quality that makes it so unique. From the very first convertible design in 1915 to modern-day marvels of retractable hardtops, we peer under the hoods to see why the convertible remains the car that everybody wants, but only a few are bold enough to own.
Episode 29: High Voltage
Look closely at those tall metal towers that span the country and you might see tiny specks climbing up the soaring steel like spiders on an enormous web. Meet the courageous linemen who erect, string, and repair 250-foot high electrical transmission towers, working with energized power lines that can carry up to 765,000 volts!
Episode 41: Loading Docks
Each day ships, trains, trucks, and planes haul supplies that keep store shelves full and factories moving. At every stop there’s a loading dock–an interface where shipping and storage hook up. You may not think much about a loading dock, but to the transportation industry it’s the very heart of their business. From ancient times to tomorrow’s lights-out facility, where computers and machines will store, sort, retrieve, and load stock without human interaction, we deliver the goods on loading docks.
