With the greatest of respect i think the technical aspects of this are too much for any non 777 technical geek to take on and mistakes will be mercilessly trashed where anomalies like control actuator motors, DC alternators, AC generators, 1KW per day etc are confidently bandied about.
Have you any idea how long and hard you'd need to pedal even an optimised generator setup to charge an aircraft battery? Or how much fuel you'd need to drive a steam generator - let alone the engineering impossibility of building one - or the engine to drive it - from aircraft parts.
You need a vast amount of very specialised knowledge and information to pull off a story like that and with the greatest of respect you haven't got past year one on basic electrical/power/engineering theory yet, let alone the type specific stuff you'd need.
