A system for reducing an evaporation and energy transfer rate between a body of fluid and an environment is provided. The shape memory alloy element is loaded by the spring towards a deflected position and is movable in response to a temperature increase and the shape memory effect activated thereby, into a position which is at least less deflected against an increasing load by the spring. In other embodiments, the cured coatings have improved slip properties and at least 6 H hardness. The vertical height of the luminaire can be adjusted by pulling one end of the cable through the track adapter. The server receives an upload command from the client computer and the upload command includes a file name. The system can provide damage attribution on a space vehicle, data gathering for debris models that are starved for information on small debris pieces, measuring density and distribution of predominantly small orbital debris in a debris cloud, and monitoring the performance of orbital debris removal efforts that target small debris.
