The solution for this problem is create a system of propellers, in specific points of the city, that work in the night hours, that propel the PP2,5 particles to high altitude, and the wind take them.

​

-  The first step is design a propeller with low weight, but with a very high resistance to meteorological factors.

- Next, we make a investigation about how much energy we save with exercise machines.

-We will present this project to the Antioquia government because they can give us the possibility to give prizes to people that make exercise and help the public health, and they can give us monetary funds to create all the project.

-We create public gyms where the people can make a good exercise in machines with special system to save the energy produced for the movement of the people in them, and with a some time make exercise, people can win prizes.

 

The advantage of this project is that we improve the people's health in 3 factors:

1. With a public gyms many people can make exercise, and get better health

2. The propeller system doesn't use a harmful energy. It use the energy that people make with exercise

3. The most important factor! we can help to the north winds to take PP2,5 particles, and clean up the air of medellín
