we missing a way to destroy this 3 items from inventory, maybe simple add a 0.1 MJ fuel value (or less) to it can be burned,
and i love the idea of players run in panic becouse run out of energy and shred the blueprint books in pieces to keep engine running
i think it needs enouth fluel value that a burner inserter can fill themself with a page and grab a 2nd page to fill themself bevore the 1st burn out
