Appears to be a very well executed dangerous idea
Placing a combustible anything on top of stove burners or elements is a bad idea.  Perhaps if it included a lockout that would key into the knobs to prevent them from accidentally being turned on, it might not be such a hazard.  But my rule is nothing that is not intended for heat is to ever go on the stove.  (I myself almost ruined our smooth top during kitchen remodeling when I placed a box of LED fixtures and electrical components on the stove top.  One of the knobs got bumped -fortunately I smelled the tape melting before there were flames, and I was able to immediately scrape off the residue before it ruined the top.  Had I left for more supplies there could have been a fire.)
