Gettin’ Clean

The primary hygiene component of a standard shipboard ‘fresher is a cylindrical translucent compartment, resembling a drug capsule set on its end, with a watertight sealing door. At top and bottom, gratings conceal powerful counter-rotating fan/turbine units.

In dynamic mode, these fan/turbines are engaged to blow (at the nominal “top”) and suck (at the nominal “bottom”) a water/air colloid past and over the bather at configurable velocities ranging from strong breeze to hurricane-strength wind, providing the water with a functional simulation of gravitic flow – a “shower”. To conserve water where necessary, many ‘freshers recirculate filtered water while in operation, requiring fresh water input only for the initial fill and the final rinse cycle.

In static mode, the gratings close and the capsule itself fills entirely with water – a microgravity “bath”.

In the former mode, breathing while bathing is, at best, difficult; in the latter, it is downright impossible. Early-model ‘freshers included a built-in breathing mask connected to ship’s life support to ameliorate this problem; in these days of respiratory hemocules which enable the modal transsoph to hold their breath for over an hour, ‘fresher designers tend to assume that this will not be a problem. Those without such hemocules must, therefore, remember to take a portable breather with them when bathing.

Dr. Kajen’s Famous Nanosalts

The crystals fizzed as they dissolved, salt lattices slipping apart into their ionic components, releasing tiny pockets of oils, aromatic compounds, and CO2 trapped within them.

Nanomachines, too, came free from encapsulation within the crystals. Their triggering conditions met – the latent heat released by the crystal’s dissolution and the presence of water molecules around them – they sprang to life, cilia driving them outward, sensors sniffing for the distinctive chemical gradient of their target. Identifying it, they swam towards its solid surface, and nanoscopic ”brushes” sprang into action, scrubbing it free of even the smallest particles of foreign matter, while other chemical armatures dissolved contamination, smoothed away damaged areas, and extended cleansing probes into its pores.
