Chalkeeper – The Never Ending Chalk
Chalkeeper is a concept that would turn chalk dust into chalks again. Teachers would use it to erase the board, but unlike standard dusters, it would absorb the chalk dust and mold it back into a piece of chalk when enough is collected. Water and heat are the only extra resources that would be used in the making of a recycled chalk. The Chalkeeper would also reduce allergic reactions from flying dust particles, as it would absorb them, unlike normal dusters.
