Shows roughly how the infrastructure works in a modern society. It’s the “general case” – to really get the detail down requires configuring the diagram for a specific place and time, but I think the rapid overview picture is still extremely useful.

A work in progress.

Five things on the chart.

1> Six Ways To Die (the target in the center.) Each ring is 10x the mortality rate, from 1/10000 to 1/10

2> Status dot showing current mortality for the population at hand.

3> Various things which impact the mortality – things like the water supply, the power grid, the food transportation grid, farms, and so on.

4> Range of those things from the individual level – individual, household, town, regional, national. Helps show what can break if networks are disrupted.

5> Simplified infrastructure interdependencies.

Observations: it’s astonishingly complicated, much more so that I’d thought it would be, and this is just a rough draft.

It’ll also show, very nicely, why the hexayurt infrastructure system is a very good idea, because that version of the graph has *almost no dependencies* on the various grids. And this makes it very, very clear.
