Abstract: A system of devices designed to release the harness lines from a rider's seat harness when rider releases the control bar (36), including a sensor strip (62), ratchet reel (70), harness line (68) and release cam (108). The system may also employ other embodiments with different operating mechanisms, all which accomplish the design objective.

Abstract: A solar energy panel and an energy storing medium for use therewith is the subject of the present invention. The solar energy panel comprises a container having a transparent pane and designed to hold an energy storing medium. By utilizing a transparent material the solar radiation is passed directly to the energy absorbing medium thereby increasing the operating efficiency. A novel energy storing medium is also used in the energy panel. This medium comprises a paraffinic or aromatic hydrocarbon having a specific gravity of less than one, a melting point higher than 50.degree. F. and a relatively high heat of fusion. By using an organic compound a medium is provided which has the desired energy storage capability and which is noncaustic and relatively light weight.
