S22E9: Life Casting, Downdraft Cooktops, Compression Hosiery, Electric Motorcycles

Flexible moulding materials capture the contours of a living subject before plaster or resin is poured to create a detailed life cast. Burners and electric heating elements are combined with built-in ventilation systems in downdraft cooktops; specialized knitting machines produce hosiery with graduated compression; and batteries, electric motors and control electronics are installed in motorcycle frames.
