Thermochemical energy storage for a lunar base [PDF]

open access: yes
A thermochemical solar energy storage concept involving the reversible reaction CaO + H2O yields Ca(OH)2 is proposed as a power system element for a lunar base. The operation and components of such a system are described. The CaO/H2O system is capable of

An investigation of the thermal shock resistance of lunar regolith and the recovery of hydrogen from lunar soil heated using microwave radiation [PDF]

open access: yes
The objective is to develop a better understanding of the thermal shock properties of lunar regolith sintered using 2.45 GHz electromagnetic radiation and to do a preliminary study into the recovery of bound hydrogen in lunar soil heated using 2.45 GHz ...

Lunar beneficiation [PDF]

open access: yes
Natural concentrations of industrially valuable minerals are far less likely to be found on the Moon than on the Earth. But that is all the more reason for devising beneficiation processes to concentrate and extract the useful mineral components in lunar
