Isn't this what they used on Tatooine?

    Quote:

    The system Wang and her students designed consists of a kilogram of dust-sized MOF crystals pressed into a thin sheet of porous copper metal. That sheet is placed between a solar absorber and a condenser plate and positioned inside a chamber. At night the chamber is opened, allowing ambient air to diffuse through the porous MOF and water molecules to stick to its interior surfaces, gathering in groups of eight to form tiny cubic droplets. In the morning, the chamber is closed, and sunlight entering through a window on top of the device then heats up the MOF, which liberates the water droplets and drives them—as vapor—toward the cooler condenser. The temperature difference, as well as the high humidity inside the chamber, causes the vapor to condense as liquid water, which drips into a collector. The setup works so well that it pulls 2.8 liters of water out of the air per day when run continuously, the Berkeley and MIT team reports today in Science.

    End quote.

    Cool.

    Dune. The generic concept has been around, but the breakthrough is definitely around the materials.

    Very cool

    My understanding is that they're working on GMO earthworms as well.

    Correct. I've been re-reading Dune.
