Three Gorges Dam: power, displacement, and silt tradeoffs

A 4-beat faceless video outline for “Three Gorges Dam: power, displacement, and silt tradeoffs” in the Engineering megaprojects explained niche, derived from caption timing of 2 reference videos.

Angles

• Open on power capacity claims, then flip to displacement and silt — megabuild references supply both awe and costs
• Engineering idea: ship locks + spillway + turbines in one cross-section
• Tradeoff board: electricity, flood control, resettlement, ecology, silt
• Earth-rotation trivia only as a sourced sidebar, not the thesis

Beat-by-beat structure

1. Hook (0:00–0:30): the world's most powerful dam — at what price?
2. How it works (0:30–2:30): cross-section of generation and navigation.
3. Tradeoffs (2:30–5:30): people moved, silt, ecosystems; sourced figures only.
4. Recap. Original narration only.
