If you’ve ever gotten too close to your gas burner while your kettle heats up, you know that not all of the heat is transferred directly to the vessel. In fact, more than 50 percent of the heat produced by the burner flame is lost before it makes contact with the kettle. Heating water for a few cups a day, combined with other cooking, results in significant energy loss over time.
Two professors at China’s Hubei University of Technology’s School of Art and Design designed a tea kettle that virtually eliminates this heat loss. The square shape and conical hole trap heat that would have otherwise moved outward, and the multiple levels of the hole increases the amount of surface area that can be heated.
The design received a Red Dot Design Award for energy efficiency.
Not digging the kettle’s hyper-modern design? You can reduce tea-related energy loss by using the smallest burner on your stove to heat your kettle.
