Graphene is a one-atom thick layer of carbon that is 200 times stronger than steel and extraordinarily good at conducting heat. But the material, discovered in 2004, has yet to generate mass-market commercial applications. The South Korean company Graphene Square is looking to change that with the Graphene Kitchen Styler, an appliance that heats up to nearly 570 degrees Fahrenheit in two minutes, with a rechargeable battery pack for outdoor cooking, and is slated for 2023 release. The device can function as an oven or grill when folded, a two-burner stovetop when open, or a warming plate. Transparent cook surfaces offer users a panoptic view of bread toasting (or steak grilling, or cookies baking) to help ensure the perfect level of doneness.
