The Sanddune Stepper is a new “balance pad system” designed specifically to treat foot, ankle, knee, hip and lower back pain. It is a simple exercise and rehabilitative method for fitness enhancement and general wellbeing. It is a low impact tool that would be similar to walking on a sand beach with an immediate bounce back effect.

We present a novel approach for numerical simulation of fluid flow and sediment transport past evolutionary landforms, with emphasis on sand dunes developing in extreme winds. Timedependent curvilinear coordinates are employed to fully couple flow aloft with the developing landform. The conservation law that defines shape of the lower boundary depends on details of local surface stress ...

Spice harvester | Dune Wiki | Fandom

A spice harvester is a large, heavy, mobile factory designed to harvest the Spice Melange. It is dropped by carrier ships (known as Carryalls) onto spice fields. These machines would then harvest and process the spice off the top of the desert floor. This immense farming mechanism is used solely on Arrakis, as it was the only known source of spice before the Tleilaxu developed a substitute.
