THE THREE LAYERS
Three frameworks, one purpose: making the thermodynamic reality of every material, action, and place finally visible.
From Odum's hidden energy accounting, through Moe's material trajectories, to Fuller and Arènes reading the same Earth from complementary positions — this is the accountability layer.
EMERGY (spelled with an M — Energy Memory) is the total available energy used up, directly and indirectly, to make a product or service. It traces every material, every process, every action back through its entire production chain to solar energy — giving us a common currency for comparing radically different things.
💡 Odum gives us the accounting ledger. Every decision an architect makes has an EMERGY cost. Now we can see it.

How the three connect
Odum's EMERGY fills Fuller's surface geography with energy values. Moe's Lagrangian trajectories trace material parcels across Fuller's map AND through Arènes's depth cycles. Every spatial relationship Fuller preserves carries an energy cost that Odum calculates, flowing through the biogeochemical cycles that Arènes draws.
