An improved swamp cooler (10) in which a D.C. motor (43), a D.C. water pump (40), a storage battery (68), and solar panel (62) are utilized to operate apparatus (10) in a self-sustaining mode without the necessity of a separate electrical source to operate the D.C. motor (43), water pump (40). Solar
An improved swamp cooler (10) in which a D.C. motor (43), a D.C. water pump (40), a storage battery (68), and solar panel (62) are utilized to operate apparatus (10) in a self-sustaining mode without the necessity of a separate electrical source to operate the D.C. motor (43), water pump (40). Solar panel (62) provides the energy source for D.C. motor (43) and water pump (40) by means of electronic circuitry (60). When solar energy is not available to solar panel (62), battery (68) in apparatus (10) provides such energy, it being recharged during utilization of solar panel (62), so that apparatus (10) continues to operate under clear skies or non-clear skies.

In a food-preparation table including (a) a table base having a top member with a top surface and pan-receiving space(s) beneath the top member, pan-supporting surfaces adjacent to the space(s), and a thermal device providing thermally-useful air in the space(s), and (b) pans in the space(s), each pan being uncovered for food serving and having a sidewall with an upper portion terminating in an upper edge, the improvement wherein: the top member, the pan upper edges, and the pan-supporting surfaces are positioned and arranged such that the pan upper edges are substantially flush with the top surface; and the sidewall upper portion of at least one of the pans has at least one inflow vent through it such that thermally-useful air in the space(s) flows unrestricted therethrough into the uncovered pan, thereby to provide temperature protection for the upper surfaces of food presented in a readily accessible position. 2. The food-preparation table of claim 1 including a plurality of the vents. 3. The food-preparation table of claim 2 wherein the sidewall of each of the vented pans has four walls, including two opposite walls each of which has at least one of the vents. 4. The food-preparation table of claim 3 wherein each of the four walls has at least one of the vents. 5. The food-preparation table of claim 1 wherein the thermal device of the table base is a refrigeration system. 6. The food-preparation table of claim 5 wherein the refrigeration system is a sole refrigeration system. 7. The food-preparation table of claim 6 wherein the refrigeration system and all parts thereof are beneath the top member of the table base. 8. The food-preparation table of claim 7 wherein: each pan has a pan bottom; and the refrigeration system includes cooling coils all of which are positioned without juxtaposition with respect to the pan bottom or sidewall of any pan, thereby to avoid adherence of food to pan surfaces. 9. The food-preparation table of claim 1 wherein the thermal device includes heat-transfer devices all of which are beneath the top member of the table base. 10. The food-preparation table of claim 9 including a plurality of the vents. 11. The food-preparation table of claim 10 wherein the sidewall of each of the vented pans has four walls, including two opposite walls each of which has a plurality of the vents. 12. The food-preparation table of claim 1 wherein the pan-supporting surfaces are part of the top surface. 13. In a food-preparation table including (a) a table base having a top member with a top surface and pan-receiving space(s) beneath the top member, pan-supporting surfaces adjacent to the space(s), and a thermal device providing thermally-useful air in the space(s), and (b) pans in the space(s), each pan having a sidewall with an upper portion terminating in an upper edge, the improvement wherein: the top member, the pan upper edges, and the pan-supporting surfaces ate positioned and arranged such that the pan upper edges are substantially flush with the top surface; and the sidewall of at least one of the pans has four walls, including two opposite walls, wherein the upper portion of each opposite wall has at least one vent through it, each vent being partially covered by a louver and the vent and louver being configured such that thermally-useful air in the space(s) flows theretrough and downward into the pan to facilitate contact with food in the pan, thereby to provide temperature protection for the upper surfaces of food presented in a readily accessible position. 14. The food-preparation table of claim 13 wherein the louver extends upwardly and outwardly from a bottom side of the vent. 15. The food-preparation table of claim 13 wherein the louver is integral with the sidewall. 16. In a food-preparation table including (a) a table base having a top member with a top surface and pan-receiving space(s) beneath the top member, pan-supporting surfaces adjacent to the space(s), and a thermal dev
