The Nuclear Option

 

Nearly six years after the earthquake and tsunami that triggered the unprecedented trio of meltdowns at the Fukushima Daiichi nuclear power plant, scientists and engineers are struggling to control an ongoing crisis at the wrecked plant. What’s next for Fukushima? What’s next for Japan? And what’s next for a world that seems determined to jettison one of our most important carbon-free sources of energy? NOVA investigates how the realities of climate change, the inherent limitations of renewable energy sources, and the optimism and enthusiasm of a new generation of nuclear engineers is seeding a renaissance in nuclear technology, all while the most recent disaster is still being managed.

Sinkholes: Buried Alive

 

In Tampa, Florida, in February 2013, a giant hole opened up under the bedroom floor of Jeffrey Bush, swallowing the 36-year-old as he slept. His body was never found. Bush was a victim of a sinkhole – a growing worldwide hazard that lurks wherever limestone and other water-soluble rocks underpin the soil. When carbon dioxide in the air dissolves in rainwater, it forms a weak acid that attacks the soft rocks, riddling them with holes. Sinkholes can occur gradually when the surface subsides into bowl-shaped depressions or suddenly, when the ground gives way – often catastrophically.
