Experts say that about 70% of the heat generated on a fire stove is lost, and this is quite a concern in terms of efficiency and conservation. The Heat-Save Kettle addresses this issue and is designed to absorb the heat-loss and regenerate it as heat energy. Essentially, you fill the ring with water, which absorbs the excess heat. The heated water can now be used for other purposes – a warm soak or tea! Designers: Li Yi, Zhang Sen, Hao Hao & Qian Cheng “compatible with conventional pots and pans and pots. The ring-style design of the base offers a bigger capacity to contain water. The patterns on the metal surface provide a bigger inner surface area to maximise heat absorption and air circulation for efficient cooking,” says designers Li Yi.
