A revolutionary chalk duster produces recursive chalk

This is pretty cool. Perpetual chalk, depending on the transmission loss…

“As you erase the board, the Chalkeeper has a tiny vacuum motor that sucks up all of the dust and stores it inside the handle. That by itself would be a big improvement over the usual chalky mess, but this concept goes one step further by combining the chalk dust with heat and water to mold new chalk sticks.”
