As an engineer, you are in charge of designing a heat engine. For your thermodynamic cycle, if you have two options for the hot energy reservoir: (A) can supply thermal energy at a rate of 200 kJ/s whereas (B) can supply at 2 MJ/s. Reservoirs (A) and (B) are also distinguished in terms of temperatures such that (A) can supply the thermal energy at 593 K while (B) can supply at 343 K. If you have only one option for the cold reservoir and its temperature is 308 K, which hot reservoir would you choose for producing a larger work output?

As per the Carnot cycle efficiency, the thermal efficiency of heat engines increases with an increase in the temperature of the heat source. An inventor has proposed to use a heat pump to transfer the heat from the source to a high-temperature thermal medium before being used in the heat engine. The inventor has claimed this arrangement increases thermal efficiency. Evaluate the inventor's claim through the thermodynamic principles.
