I want to know the answer to the following question:
What was used to power the plants engine?
All the background I'm provided with is that "Shuman’s plant used parabolic troughs to power a 45–52 kilowatts (60–70 hp) engine that pumped more than 22,000 litres (4,800 imp gal; 5,800 US gal) of water per minute from the Nile River to adjacent cotton fields.". Is that enough to answer the question?
