    33.4KW

    Explanation:

    Firstly, we calculate the power index in a reversible heat engine which is given as;

    n = 1 - T1/T2

    T1 = atmospheric temperature 298k

    T2 = reservoir temperature 1500k

    n = 1 - 298/1500

    n = 0.8013

    output energy = n * energy input

    0.8013*150000 = 120195KJ/hr

    Power output = 120195KJ/hr/3600 = 33.4KW
