Chalkeeper : Create a New Chalk From Chalk Dust
Maybe now some schools prefer to switch to a whiteboard or markerboard than having to use a chalkboard or Blackboard, one of the reason is when using whiteboard, markers does not generate the dust that comes from using and erasing chalk which can lead to respiratory disorders. then what if there are schools that still use chalkboard ? the answer is Chalkeeper
Chalkeeper is a concept design by Yonggu Do and Eunha Seo that basically a chalkboard eraser that can suck up the chalk dust, then uses heat and water to create a new piece of chalk from the chalk dust that had collected earlier. interesting concept although I don’t know how the quality of this recycling chalk and how much chalk should be used to collect enough chalk dust that could be a new piece of chalk.
