There is such resourceful logic to the design of the Twist Stovetop Kettle that makes you wonder why plenty of others like it aren't already on the market. This simple water-warming appliance is more impressive than most because it promises to reduce the amount of wasted water and energy that other kettles emanate so excessively.
Hakan Gursu designed a hollow lever-like handle that spins around to connect to the open spout. As the fluid inside boils, vapor might pass through the arching aluminum tunnel but it will not escape from the vessel. A sealed pressure valve in the lid accounts for the increasing inner imbalance and all H2O is conserved throughout the boiling process. Acting like a thermos, the Twist Stovetop Kettle keeps the warmth in the liquid for longer.
