The primary application of AMWAS is for production of clean water from Mars soils for electrolysis, fuel and oxygen production, food production, and radiation shielding. The AMWAS can provide a reliable, low-cost, low-mass technology to produce water, hydrogen, and liquid oxygen on the surface of Mars out of indigenous materials at low power. The ability to extract water from Mars could also serve to supply the crew of Mars missions with water, which is the second most massive logistic component of a Mars mission. Smaller versions of the AMWAS could be used to help make the return propellant for a Mars sample return mission on the Martian surface, thereby making such a mission both cheaper to launch and much easier to land.
The AMWAS could be implemented in arid terrestrial climates for recovery of water from soils. Even in the driest regions of Earth, the regolith is several times wetter than on Mars, and the AMWAS can operate efficiently under those conditions. Regions that are too far from the coastline to economically pipe water may be potential markets. Units sized for vehicles traveling in desert regions could reduce logistical requirements for the military and civilians operating in remote areas, since it is very lightweight, cheap, and portable. By enabling agriculture in arid areas the AMWAS could also support the production of renewable energy in the form of biofuels.
