What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.
Foundations · builds on
Heat enginedepends onHeatEstablished
heat engine depends on heat.
Mechanism: A heat engine runs on heat: it draws energy from a hot source, converts part into work, and dumps the rest to a cold sink.

Gas turbine is a kind of Heat engine.
Power plantis aHeat engineEstablished
Most power plants are heat engines.
Mechanism: A fuel heats water to steam that spins a turbine, turning heat into electricity — a heat engine at scale.
Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: no key date stored · 9 of 9 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Builds on 3 foundations (requires / depends-on / derived-from / emerges-from).
structural · Structural graph analysis — not a claim of importance, causation or history.
Structural neighbourhood: 9 → 24 → 86 concepts reachable within 3 hops.
structural · Structural reach — being reachable is not the same as being understood.
All 9 of its relationships stay within its own discipline — a field-specific concept in the current atlas.
structural · Structural graph analysis — not a claim of importance, causation or history.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Its dependency reading rests on 3 foundation relations. structural
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
