PROBLEM TO BE SOLVED: To provide receptacles such as a mug with a display.SOLUTION: A coffee mug comprises an energy harvesting element 101, such as a Peltier element, for harvesting electric energy from the temperature difference between a liquid 102 and an ambient of the receptacle 100. In addition the mug comprises a data processing device 103, a display device, and a data communication device 105 for receiving data wirelessly from an outer application system. The energy harvesting element 101 is configured to supply electric energy to the data communication device 105, data processing device 103, and display device. The data processing device 103 is then configured to receive the data via the data communication device 105 and control the display device to display the received data. |
