INVISIBLE UMBRELLA

INTRODUCTION : Designers from “Nanjing University of Astronautics”

have come up with an impressive innovation in the field of

technology, with their invisible umbrella.

The product uses motor to propel air in every direction,

causing rain water to disperse away from the user.

WORKING : The “INVISIBLE UMBERLLA” consists of a “Narrow

handle” with a “Wider circular head”. The head contains a

“motorized fan” that sucks in the air from below and blows it

outward. The narrow handle house a lithium battery that lasts up to

Thirty minutes in some models with a single charge. At the base of

the handle is a controller, which can be rotated to control the force

with which the airflow can be carried out. Below this is the power

button.
