Pendulum Oxygen Rebreather Umbrella

The Pendulum Oxygen Rebreather Umbrella employs advanced aerodynamics to harvest atmospheric oxygen while providing reliable rain protection. As wind forces shift, an intricate pendular mechanism adjusts airflow through miniature turbines, extracting O2-rich air particles within a radius of five meters. This results in breathable air quality identical to natural environments. In emergency situations, users may activate the umbrella's rebreathing mode by shifting their weight onto either foot tip. The altered center of gravity triggers synchronized flapping motions, generating sufficient negative pressure to draw polluted air into miniaturized filters before recycling clean oxygen back into the atmosphere around the user.
