Since the first handheld computer appeared in the last century, energy technology has been greatly developed. As a way to demonstrate these technological advances and how we may lead in the future, < / P > < p > is a self-contained game system developed by scientists from Northwestern University and Delft University of technology in the Netherlands, who are exploring the limits of battery free computing. The system features a retro 8-bit Nintendo game boy processor that can run the Yuan Dynasty cassette games. This, the team points out, actually requires considerable computing power and energy. < / P > < p > but instead of turning to batteries to provide continuous power, the team has embedded solar panels at the edge of the screen, working in conjunction with a capacitor based system, to collect energy from the user device interaction (each time the user clicks a button). “This is the first battery free interactive device that collects energy from the user’s actions,” said Josiah Hester of Northwestern University, who co led the study. When you press a button, the device converts that energy into something that powers your game. ” < / P > < p > the team said that under typical game conditions, these interruptions last less than a second, which is feasible for games such as Tetris or solitaire. But for more action oriented games, it needs further optimization. On the positive side, the system can save users’ progress at the moment of power failure, allowing them to continue playing from where they left off. < p > < p > co led the study, Przemyslaw pawlczak of TU Delft said: “sustainable games will become a reality, and we have taken an important step in this direction – completely getting rid of batteries. We hope to make a sustainable development game system in the future to bring fun and joy to users. Global Tech
