US Patent 11602712 Atmospheric water extraction system

A water sorption device includes a catalytic combustor configured to, in a desorption state, combust a hydrocarbon fuel mixture to generate heat; a thermoelectric generator configured to, in the desorption state, generate electricity from a first portion of the heat from the catalytic combustor; and an adsorber configured to in an adsorption state, adsorb water from ambient air from an environment and in the desorption state, desorb the adsorbed water as vapor using a second portion of the heat from the catalytic combustor.
