| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Electricity (electricity) | enabling | 68% | expert_inference | Electricity provides a capability that enables this technology without being the only possible path. |
|
| Steam Engine (steam_engine) | commercial_or_scaling_dependency | 55% | expert_inference | Steam engines supplied mechanical power for later generator deployment, but Faraday's early generator principle did not require steam power. |
|
| Classical Monumental Construction (construction) | enabling | 68% | expert_inference | Construction provides a capability that enables this technology without being the only possible path. |
|
| Early Electromagnetism (electromagnetism_early_discoveries) | historical_predecessor | 75% | expert_inference | Early Electromagnetism is an earlier historical predecessor or foundation, not a one-to-one engineering dependency. |
|
| Copper Wiring Production (copper_wiring_production) | enabling | 68% | expert_inference | Copper Wiring Production provides a capability that enables this technology without being the only possible path. |
