Splash! Festival in 2020

When I'm visiting the Splash! Festival (for Hip Hop / Rap music in Germany) the equipment used to generate power for the concerts will have changed totally. The tents, where the music is played, are covered with solar modules, so that sun energy can be saved over the day and used in the night, when it is dark outside. Furthermore there are bio-power plants around the area, so that the huge amount of waste and excreta can also be used to generate power. At last there is a totally new technology used to light the main stages: the area, where the audience is staying, jumping and partying is covered with plates. Everytime, people move on it or jump, the plate is pushed down and power is generated. The more the people are moving, jumping or partying, the brighter are shining the lights on the stage.
