Miito Induction Kettle
It's a huge waste of energy to heat more water than your need for your coffee or tea. Unfortunately, most kettles weren't designed for single servings. The Miito Induction Kettle is. As the title suggests, it uses induction technology to heat only the water you need by letting you place the heating rod in your vessel of choice, then place the whole thing on the base and let it boil. It also lets you heat other liquids like soup and sauce, making it a useful addition to any kitchen.
