Protection from the Rain – The ‘Air’ Umbrella.
The ‘Force Field’ Umbrella was developed by scientists in China, in Nanjing University in the course of two years. This design does not require the metal poles like other umbrellas. This device works by producing a shield of air around your body, preventing you from getting wet, also reduces the noise produced to a minimum. This device is operated by a lithium battery, a fan and a motor that provides an uninterrupted cycle of air flowing from the tip of the umbrella. The design team has come up with three models that differ in battery life and coverage space. They have 30-minute and 15-minute battery lives. The device takes 30-minutes to charge.
