He barely touched upon the engines behind APU's in this video. Go check out the APU in b-29's. That was an internal combustion engine. As with many large aircraft, even after the jet-engine became readily available. Eventualy, jet-based APU's did take over. But it sound allmost like APU=small jet-engine here. That's certainly not the case.

this video should be renamed as purpose & history of APU.
