Imagine a solar electric power plant that operates by using a gigantic mirror to concentrate light on the boiler for a steam engine. Assume that the boiler generates steam at a temperature of 550°C. The only possibility for a cold-temperature reservoir is a nearby creek that has an average width of 4 m and an average depth of 0.7 m, flowing at a rate of 0.7 m/sec. What is the maximum electric power that could be produced by the plant if it boils the entire creek dry?
