Abstract
Abstract A STEAM POWER PLAT FOR USE IN PROPELLING VEHICLES HAVING A RESERVOIR INTO WHICH THE WATER OR CONDENSATE IS DRAINED WHEN THE ENGINE IS SHUT DOWN. THE CONDENSATE IN THE RESERVOIR ABSTRACTS HEAT FROM A THERMAL ENERGY STORAGE MATERIAL WHICH IS HEATED BY A HOT FLUID STREAM FROM THE STEAM POWER PLANT SYSTEM DURING ITS OPERATION. THE HEAT STORED IN SAID MATERIAL PROTECTS THE WATER OR CONDENSATE IN THE RESERVOIR FROM FREEZING DURING NONUSE PERIODS OF NORMAL DURATION AT LOW AMBIENT TEMPERATURES.
