Rotating broom

Because of anomaly climate due to environmental pollution,
it snows much in winter. When snow falls,
one should necessarily sweep the road in front of one’s house
to prevent injury by slipping. At normal times, the broom can
be used for cleaning, and by changing the motion energy in
to electric energy, it can be used as broom for snow removing.
The sweeper of the broom rotates so it can more easily and
quickly remove frozen snow in the ground.
