Documentary which follows the construction of a trailblazing 36,000-tonne steel structure to entomb the ruins of the nuclear power plant destroyed in the 1986 Chernobyl disaster. It films close up with the team of international engineers as they race to build the new structure before Chernobyl's original concrete sarcophagus - the hastily built structure that covers the reactor - collapses. Built to last just thirty years, the temporary sarcophagus is now crumbling, putting the world at risk of another release of radioactive dust. Radiation levels make it impossible for workers to build the new shelter directly over the old reactor, so engineers are erecting the new megastructure - taller than the tower of Big Ben and three times heavier than the Eiffel Tower - to one side and will then face the challenge of sliding the largest object ever moved on land into place over the old reactor.
Special access to Tesla's record-breaking Gigafactory reveals its bold ambition to build one of the most advanced cars in the world; this cutting-edge facility is one of the world's largest, representing the frontier of engineering innovation.
This episode will show how innovations in construction are burgeoning: 3D printing, material salvaging... In cities, homes will be modular and “intelligent” and the growing population will lead us to explore new spaces on Earth and even other planets...
They are constantly circling hundreds of miles above our heads, driving our daily lives - yet we barely give satellites a second thought. Satellite engineer Maggie Aderin Pocock wants to change all that. She wants to make us realise and appreciate what these unsung heroes of the modern world have done for us. Maggie reveals how satellites have revolutionised exploration, communication, location-finding and spying. She discovers how they have transformed not only the way we see our planet but our understanding of the dangers within it, like volcanoes and earthquakes. Plus, she discovers the jaw-dropping power of the technology used by satellites to make our lives run smoothly.

Join Steven Johnson and consider how the invention of the mirror spurred on the Renaissance, how glass lenses allow us to reveal worlds within worlds and how, deep beneath the ocean, glass is essential to communication. Johnson learns about the daring exploits of glassmakers who were forced to work under threat of the death penalty, a physics teacher who liked to fire molten glass from a crossbow and a scientist whose tinkering with a glass lens allowed 600 million people to see a man set foot on the moon. The link between the worlds of art, science, astronomy, disease prevention and global communication starts with the little-known maverick innovators of glass.
