Blade less wiper / Blade less wind screen wiper

Blade-less Wiper,
Conventional Wipers are not necessarily the only way to clean wind screen.
Idea of Blade-less wiper is based on making a tangential air curtain on wind-screen generated by a brushless fan and a specific air-channel.
The wind-screen is covered by non-stick nano coating to improve the efficiency of wiping-system.
A control circuit manages the optimal fan-speed depending on the velocity of vehicle and ambient conditions.
Blowing warm air on wind-screen is another helpful function of the blade-less wipers to melt down frosted windscreen quickly in winter.
Eventually the car window is cleaned silently, completely and sustainably
