A solar energy collector produces a maximum temperature of 100°C. The collected energy is used in a cyclic heat engine that operates in a 5°C environment. Estimate the thermal efficiency if the engine operates at 40% of Carnot efficiency. How would the answer change if the collector were redesigned to focus the incoming solar radiation to enhance the maximum temperatures to 400°C.
