    Nice!

  2. For your interest, here is average monthly data on the water-from-air
    resource in Lima, Peru. The units are for water vapour density [grams of
    water vapour per cubic metre of air]

    Jan 15.2, Feb 16.2, Mar 16.2, Apr 14.3, May 13.5, Jun 12.7, Jul 11.2, Aug 11.2, Sep 11.2, Oct 11.9, Nov 12.7, Dec 14.3

    The billboard’s water-from-air machine (or atmospheric water generator)
    will be a maximum of about 58% efficient at removing water vapour from
    the air in February and March. In July and August, the machine’s
    dehumidification efficiency drops to 39%. These efficiency values
    presume that the chilled surface in the machine is maintained at 5°C.

    The energy typically needed by dehumidifiers to condense water vapour into
    liquid water is approximately 0.4 kWh per litre of product water.
