1. A water harvesting system, comprising:
a heat pump having a condenser and an evaporator, wherein said condenser comprises a hot side of said heat pump, wherein said evaporator comprises a cold side of said heat pump;
a first chamber containing a water capture material,
said first chamber encompassing or positioned in close proximity to said hot side of said heat pump,
said first chamber operates in an adsorption mode in which said water capture material captures water from surrounding air,
said first chamber operates in a desorption mode in which said hot side of said heat pump transfers heat to said first chamber to desorb water vapor from said water capture material; and
a second chamber fluidically coupled to said first chamber, said second chamber encompassing or positioned in close proximity to said cold side of said heat pump,
said second chamber operates in a condensation mode to receive water vapor from said first chamber,
said cold side of said heat pump transfers heat from said second chamber to condense said water vapor to liquid water.
