There are 758 billion people suffering from illiteracy (above 15 years) and 1.3 billion who do not have access to sufficient electricity. One consequence is that children have to work to support their family financially. Our pen should generate electricity (through frictional electricity or the piezo effect) that got saved in a battery. This battery can either load a LED light bulb or can be used as another source of electricity. Our aim is that children can support their family with bringing home light and simultaneously learn how to write. This could fight child labor, illiteracy and simplify access to light.
