Windshield wiper in snowy and cold weather get frozen and it takes time to get defrosted my idea is about a new wiper that is not electrically heated like what is in the market because this one only heats the blades and not the wiper arm.
The new wiper mechanism uses hot air to warm up the whole windshield wiping system and windshield by a copper heat exchanger which receives heats from engine manifold and air can be supplied by many means from the engine or a simple fan.
