WAAIER

WAAIER is a small hand-held and hand-powered fan concept. The user holds the fan between the index finger and thumb and manually pushes the leadscrew inwards repeatedly.

It utilizes a custom proportioned leadscrew to translate pushing motion into rotational motion. An overrunning bearring coupled with regular ball bearrings allow this motion to be transferred to the fan blade while the parts that the user holds between the fingers remain stationary.
