SCENARIO — THE DASHBOARD GOES RED
The grid is unstable. The internet is fragmenting. A fake government voice message is spreading faster than the real warning. The supermarket still has food but payments are failing. You have one power station, some bottled water and no idea whether that means six hours of resilience or three days.
The calculators above answer the boring questions before the fictional nightmare makes them urgent. The rest of the toolset deals with the human problems: family plans, evacuation, deepfake scams, AI dependency and disruption scenarios.
Family, scenario & AI-risk tools
Why the tools are free
A useful survival site should do more than describe a nightmare. These calculators solve individual planning problems immediately. The deeper problem is sequence: what to do first, which decisions depend on one another, and how a household moves from the opening hours into a longer disruption. That is what the 72-Hour Manual and the larger survival system are designed to organise.
