‘Gradient’ by Dmitriy Shcherbakov is another innovative portable device designed to maintain a constant temperature of your beverages. The heating surface of the device keeps your cup warm, while the impeller located at the top of the case chills your beverages. This portable device also comes with a LED display to highlight the current temperature and a LED light to inform you whether it’s on warming mode (red) or chilling mode (blue). The whole system runs on electric power (consuming 20 W). Sadly, no word on pricing and availability yet. [TheDesignBlog]
