Since long time ago, artists were using grafite to draw. Pencils were and still are a great tool for artists of any kind, writers, painters, even photographers. Each and every one of these uses pencils to create sketches, to write notes. And after a little while, they also need to sharpen them. A gesture related to art. Art that, sadly, appers to many people “unuseful”.
How can be prove they are wrong?
Converting artistic action in electric current, energy will be produced. Energy that could enlight a world, a world that needs to be enlighted.
