I have a half written FATE campaign that starts off with making the players thinking it’s an isekai until about session 3 when I corner them with enemies, play this, and give them their I am thou, thou art I speil; surprise you fools you thought it was an isekai deconstruction but it was Persona the whole time!

According to priuschat you can leave your prius “idling” with light duty power draws (a small lcd tv and a fan) for about 7 days on a full tank of gas.

Also I think on the prius the starter motor-generator is also the one that bleeds excess engine power to charge the battery, but I’m not 100% sure on that one.
