Final answer:
The question about the duration of fuel storage for emergency generators does not have a definitive answer provided within the context of the given hints or references. The concept of power generation is involved, such as how many people would be needed to pedal at 100 W each to power electrical devices or replace a power plant.
Step-by-step explanation:
In the context of the emergency fuel storage capacity question provided, the duration for which the fuel storage must be capable of running the generators is not explicitly stated within the hints or reference information given. Therefore, without specific guidelines or regulations mentioned, we cannot definitively answer the question about the required operational time of generators during an electrical power loss.
However, to provide conceptual insight from the provided physics problems: a person in good physical condition can output 100 W of power. This relates to the concept of power generation and energy conversion efficiency. For instance, to run a 4.00-kW electric clothes dryer, it would take 4,000 W / 100 W per person = 40 people pedaling continuously without rest. To replace an 800 MW electric power plant, it would require 800,000,000 W / 100 W per person = 8,000,000 people.
