Seeking recourse to jellyfish as a source of inspiration for powering gas-filled balloons is an obvious thought; after all, a jellyfish consists of water to 99%. Its weight-to-volume ratio is approximately 1, and the figure is similar for a gas-filled balloon. Jellyfish fossil finds indicate an ability to survive dating back more than 500 million years. Jellyfish have thus repeatedly adapted to various environmental and living conditions and have become veritable survival artists; the diversity of jellyfish species suggests a high degree of adaptability.
