No, it is a 777 that has crashed on an island without anything modern on it. They have to scavenge the plane to make their needs met.
The plane is about 2 miles from the settlement, so running cables to the APU is problematic. Moving the APU is possible, but according to someone else, there is only about 15hrs of operation on 1,000G of fuel. The APU appears to be quite expensive to run for power. It is overkill for their needs - maybe in their future.
The only way to go is:
a) Windmill
b) Steam
Since there are 28V AC alternators on the plane, along with the electronics to deliver both 28V DC and 115V AC and I think three 28V DC batteries, that seems to need to be the heart of the power generating system. Initially, they will use wind to turn the alternators, later they will shift to steam.
There is also a 11-speed mountain bike in the cargo hold. They will use the 10:1 gearing on the bike to convert the 500 RPM wind speed to 5,000 RPM the alternator wants to run well.
With long enough blades, there should be sufficient torque/power to drive things.
Other suggestions are welcome.
