Must be something in the water…

Engineers have found a new class of materials that harvest water from air, no energy needed. These nanostructures absorb moisture, store it, and release it onto surfaces.

ELON ON STARSHIP TILES: SUPER HOT PLASMA DOESN’T CARE ABOUT YOUR IDEAS Some are floating the idea of ditching Starship’s tiles for a balloon-like reentry body made of bare stainless steel, or overlapping heatshield tiles. Elon explained the difficulties of the engineering involved: “The angle of attack is significantly different during ascent, hypersonic flight and subsonic flight, so it is hard to overlap tiles consistent with the direction of air flow. Also, super hot plasma water-falling over the height differences between overlapping tiles would create heat concentrations that erode the tiles.” Although he did say that "Giant steel dragon wings would be sick."
