Abstract
A dining table which automatically maintains food at an optimum temperature all the while the food is on the table. Disposed beneath the table top, which permits flux linkage therethrough, is apparatus which generates one or more electromagnetic fields with each of the fields of influence thereof extending upwardly through the table top. Placing a peculiar food vessel within each field of influence causes an electromotive force (EMF) to be generated within conductor windings disposed therein. The food vessel also includes a heating element which is connected to the conductor windings; this heating element is powered by the EMF being generated by the conductor windings. Thus, a nominal amount of heat is developed which keeps the food contained within the food vessel at an optimum temperature.
