A human culture develops during the height of global warming. This culture has a coming of age ritual where a young person is put outside during wet bulb temperatures that may kill them.
Those that survive without difficulty, join a privileged class of humans that are allowed to explore outside. Those that fail and return early are confined to a life underground, working in the factories. The two classes are not allowed to interbreed.

The event space produces energy from solar and stores it on site as hydrogen. The site has a minimal production capacity for energy from hydrogen, but massive storage. When hydrogen fuel cell powered cars, carrying people, show up at the event, they plug into the hydrogen power system. Each vehicle being refueled and used to produce extra power for the event.
While the event space sits idle, it produces energy for the local community.
At home, the vehicle connects to the home energy grid. A sort of mobile battery.
