This invention relates to a system for automatically self-adjusting the height, length and direction of an electrical power cable connecting a movable machine, such as a crane, to a fixed electrical power supply. The tubular enclosure is fabricated of a microporous material that has microfiltration properties: it is hydrophobic, so that soil water will not enter the enclosure, but also oleophilic to enable petroleum and related substances migrate through the material of the tubular enclosure and accumulate therein. The method and apparatus provides for re-establishing dedicated traffic channels for the talker mobile and the dormant listener mobiles advantageously in parallel. The inner cavity is lined with stimulation material configured to contact the surface of the penis. 015 as a system in its entirety.
