SOS by chi wei Kuo from taiwan

SOS is an emergency help system. In addition to emergency helium balloons, it is also equipped with LED lights and speakers, increasing the chance for recognition at night and the speed at which people can be discovered in the wilderness. This design will facilitate searches in the wilderness so rescuers can find the location of the lost people easily in a short amount of time. This will shorten the rescue time of the rescue workers, and increase the speed of salvation.
