I would want to invent a portable water purification device that uses solar energy. Access to clean drinking water remains a critical issue in many parts of the world, and a compact, efficient solution could significantly improve health and quality of life. By harnessing solar power, the device would be sustainable and suitable for remote areas. This innovation could empower communities and reduce the burden of waterborne diseases.
