Treasure Hunters

For thousands of years, they lay dormant in the soil until suddenly, they became the driving force behind a technical revolution. Smart phones, laptops, touch screens, wind turbines, hybrid vehicles: they all needs rare earths. Now physicists and chemists continue to work on ground-breaking new materials that could soon replace rare earths completely. A fascinating glimpse at cutting-edge research that could make our green technologies of the future even greener.
