An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable (8) as seen in FIGS. 1A and 1B. The trolley comprises front and rear pulleys (44F) and (44R) conjoined via pulley housing (16) with left and right horizontal handles (10L) and (10R) attached to vertical shaft (12). Front and rear hand brake levers (20F) and (20R) are mounted onto left and right horizontal handles (10L) and (10R). When front and rear hand brake levers (20F) and (20R) are squeezed by the rider, they create a constricting force on front left and right calipers (32FL) and (32FR) along with rear left and right calipers (32RL) and (32RR) of FIGS. 2A and 3A. Thus, friction is applied to front and rear pulleys (44F) and (44R) via front left and right brake pads (34FL) and (34FR) along with rear left and right brake pads (34RL) and (34RR). This frictional force slows the rider's speed to his or her desired rate and brings the rider to a safe stop at a precise location along suspended cable (8).

A system of recirculating ducts insures that air within the interior of the cart is run through the air conditioning unit and then returned to the cart interior after it has been cooled so that recirculating air and not exterior air is cooled or heated depending on the setting of the air conditioning unit.

Method of cyclic anchoring itinerant (CAI) propulsion uses a phenomenon of anchored float horizontal motion as wave rises. The method repeats a cycle: Detaching the anchor from an immobile medium as a wave begins descent; Accelerating it in new position as the wave descends; Reattaching it to said medium as a wave rises. The medium can be railway or water. Respectively a trolley or a glider works as the anchor. To drag as anchor the glider orients perpendicular to the link. Improvements: adding an auxiliary propeller accelerating the glider, connecting bow and aft gliders with a single boom, making it telescopic, adding a small submarine hull for permanent observation water space, scientific researches, entertainment. The method allows to reequip watercrafts to all-weather, ocean going watercrafts with an unlimited range of operation. These solutions can be widely used in marine rescue remedies. Experimental models of CAI propulsion system show remarkable results.
