The deathstill featured in Dune Part Two is an inefficient way to store water, even with mitigation techniques like the Persian ab-anar, water would be lost at an unacceptable rate in an environment like Arrakis.

This is why the only Dune I care about is this dune-buggy I stole from NASA.

Someone should tell Guillermo del Toro that pine wood is uniquely unsuitable for the making of a boy.

With a density as low as 0.28g/cm3, it's nowhere near the correct density of a human boy, roughly 1g/cm3.
