-> Collect and use the energy generated by the pressure of our steps on the ground!
As a greedy consumer of energy, the cultural sector should also change its way of working and consuming.
Piezoelectricity is a helpful tool to achieve this. Its concept is to convert kinetic energy into kWs.
In this way, the energy produced by people walking could be transformed into electricity which would then be used to light up spaces (Theaters, museums…), or to power monitors..
Do we have any examples? A soccer field in Brazil, a club in England, a train station in the North of France, all of them are already using piezoelectricity.
What is preventing us from using it arts centers? After all, there are so many tourists and audience members who walk in them. Let’s not waste it anymore!
Our project aims to use the kinetic energy of the audience of a music festival to be able to generate enough energy for their electrical needs.
Are you ready to dance and become a human power generator?
It's Hajer BEN FEKIH's idea, who is a student in a Master degree in MODO (Modélisation Optimisation, Décision et Organisation) at Paris Dauphine University.
She told us that she is working in her Fablab on a shock absorber for cars with an electricity generator integrated in it. The electricity generated by cars passing through could possibly be stored and be used to light street lamps.
We all already know about windmill, solar energy or hydroelectricty. Any ideas of what piezoelectricity is?
Oxford dictionary tells us: Electric polarization in a substance (especially certain crystals) resulting from the application of mechanical stress. Piezoelectric substances are able to convert mechanical signals (such as sound waves) into electrical signals, and vice versa. They are therefore widely used in microphones, gramophone pickups, and earphones, and also to generate a spark for lighting gas.
It sounds all complicated but in fact the mechanism isn't. Anybody could by walking and therefore indirectly putting pressure on piezoelectric paving stones create electricity.
Imagine a stage made out of piezoelectric paving stones. By moving around and being creative, artists could create enough energy to light up their performance and be selfsuficient.
Hajer and her team are at the moment working on this project and we are there to support them and hope to present this project publicly very soon.
