Abstract
A spherical inflatable solar concentrator is proposed for use on the Martian surface with potential for high mobility and convenient sun tracking as well as high peak temperatures. A rover inside the inflatable concentrator is able, by moving along the floor, to cause the structure to roll such that the interior concentrator mirror can be aligned with the sun (sun tracking) over the course of the Martian day. Comparison is made to conventional solid mirror heliostats suggesting the investigated approach may offer significant advantages in flexibility as well as lower system mass and size. Applications for early stage processes well suited to the proposal are suggested, its strengths being in processes requiring high power consumption and maintenance of elevated temperatures for sustained periods, such as carbochlorination, zeolite manufacture and pneumatic gas heating. Presently unsolved issues are then examined and future directions for research suggested.
