The idea consists in using gravity to make an escalator without using electrical energy.
It can be used in a place where people want to go up and down, like the entrance of a subway.
We concentrate people that want to go down in a platform, then the people that want to go up stay in another platform .

These platforms are connected by pulleys in order to guarantee that the weight of people wanting to go down will generate enough potential energy to move the platform with people that want to go up.

The balance can be upheld by cords, that people can pull to control the movement.
The fun is in the connection among people, because the mechanism only works with cooperation in both sides.
