The main goal of this submission is to combine leisure / to appeal on the social responsability of the people / green energy in one, while having something new, something innovative. "Charge you battery" having 2 aspects (human & electronics):
1. charge "your own battery" while resting on the bench
2. charge your electronical devices (if needed)
The idea is to spread multipurpose covered / innnovative benches all over the city. As mentioned, the bench is covered, having a solar cell on the on the roof, which supplies the USB / plug with electricity. People walking around in Berlin just can take a seat, relax, and while relaxing charging their cell phone / tablet / laptop. On the side of the bench they will find an USB port + plug connector. There will be a display which shows: 1. the amount of money saved with the charging in euro (electricity used for charging), 2. the actual stand of the electricity supply (whether there is enough electricity to charge), 3. QR code.
The app can (shall) be downloaded, and does the following: based on the amount saved while charging, the one who downloads the app can make a donation (the amount will be automatically completed - default value of the amount would be equal with the saved amount by charging - but this amount can be changed manually). With this donation the Berliner Sparkasse can support several projects, especially those ones which provide help towards socially and culturally handicapped people. The Sparkasse originally “intended to develop solutions for people with low income to save small sums of money and to support business start-ups”. Exactly this is the point where this idea would like to connect to the history, to the main goal of Sparkasse. The amount of money saved based on the electricity used while charging will be a small amount, but each and every cent donated counts, it can help to make the life of a lot of “Berliner” better.
