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.

This documentary presented by Professor Simon Schaffer describes the amazing story of automata Designed and built with pen and paper in the 18th Century leveraging the mechanisms employed in making timepieces, these mechanical devices containing 1000’s of parts and are programmable to mimic human actions in Mechanical Theatre. The program describes how there development has led to the creation of the mechanical devices we take for granted today showing the first mechanical weaving looms allowing for the mass production of fabrics and in effect started the industrial revolution.

NOVA takes you inside the historic international race to develop the first supersonic airliner, the Concorde. Hear stories from those inside the choreographed effort to design and build Concorde in two countries at once—and the crew members who flew her. Then, follow Concorde’s legacy to a new generation of innovators reviving the dream of supersonic passenger travel today.
Electricity powers the life support systems that keep our cities running. Lights, transport, communications, and even hospitals rely on this invisible force. Without it, our cities come to a standstill and lives are put at risk. Meet the people who spend tireless hours to make sure that city power grids remain safe, efficient, and uninterrupted
Mankind has always looked at nature to solve problems, taking a cue from the solutions that biological systems have refined through natural selection. In this episode we look at a robotic plant that mimics the mechanics of plant roots, and dive underwater to see robots inspired by fish.
