Question 42

In a conceptual nuclear fusion reactor, the total mass of the reacting fuel decreases at a rate of 1.8×10−5 kg hour−11.8 \times 10^{-5} \text{ kg hour}^{-1}1.8×10−5 kg hour−1 due to fusion reactions.

What is the maximum electrical power output of this reactor, assuming 100% efficiency in converting the released mass-energy into electrical energy?
