The sea level in Venice has increased drastically in the last century or so, threatening the very existence of the city. Global warming and the harmful effects of tourism have amplified the phenomenon of acqua alta (sudden rise in sea level), rendering the traditional responses of inhabitants obsolete. It is urgent to act today. Projects conceived in laboratories across the globe are joining forces to save the city. These include RAMSES, a 3D modelization of the lagoon produced using lasers, which analyzes rises in water level; and MOSE, a series of movable dams costing over 4 billion euros, intended to block the sea in case of acqua alta. The film will take us on this extraordinary journey, the technological and scientific struggle for the survival of Venice, a survival that has been in doubt from its very construction.
Take to the sky with the dreamers whose work gave humans the ability to fly. From Leonardo da Vinci’s “flying machines” to the modern commercial plane, without these inventions, we may have never left the ground. Narrated by Patrick Stewart.
The Boeing 787 according to its manufacturers is a revolution in air travel. Similar to the Airbus A380, the plane is made from carbon fiber reinforced plastics and aluminum glass fiber materials which are lighter and more resistant to fatigue. It is one of many planes that have been developed to reduce the carbon footprint while improving space, comfort and entertainment for its passengers.
Can new engineering techniques help prevent deadly bridge collapses? In 2018, Italy’s Morandi Bridge collapsed, tragically killing 43 people. For 50 years, the iconic bridge had withstood the elements—and stress from ever-increasing traffic. What went wrong that fateful day? And how can new engineering technology protect bridge infrastructure to prevent such tragic failures in the future? Through eyewitness testimony, expert interviews, and dramatic archival footage, NOVA investigates the Morandi disaster and other deadly bridge collapses.
