  • Ice Gurus

    Ice tailoring appears to be the new Olympic challenge. Ice must be tailored to each athlete's needs, e.g. long-track speed skaters prefer a surface as low as -7 to -8°C, whilst figure skaters need to dig their skates into the ice in order to pull...

  • Radiative Cooling in the Sub-Saharan Desert

    A new way of lowering temperatures without using electricity has recently been developed. Iterrae, a French company, has discovered a way of using radiative cooling, a phenomenon that takes place at night, when the Earth is cooled by the 0 K...
