# Seastead Design Analysis

This document analyzes the proposed seastead design, focusing on buoyancy, stabilization, power systems, and costs.

## 1. Structure Weight Estimate

### Main Components:
1. **Triangle Frame (40 ft sides):**
   - Aluminum box beams 40 ft long × 6 in × 4 in cross-section
   - Volume per beam: 40' × 0.5' × 0.333' = 6.67 ft³
   - 3 beams: 20.01 ft³
   - Aluminum density: 0.098 lb/cu.ft.
   - Weight: 20.01 × 0.098 = 1.96 tons = 3,920 lbs

2. **Living Area (12 ft wide, 8 ft high):**
   - Volume: 12' × 12' × 8' = 1,152 ft³
   - Weight: 1,152 × 0.098 = 112.9 lbs

3. **Floats/Wings (3 total):**
   - NACA foil shape, 19 ft long, 2 ft chord, 1 ft thickness
   - Volume per float: Approximate using wing volume formula
   - Each float: 0.5 × 19' × 2' × 1' = 19 ft³
   - 3 floats: 57 ft³
   - Weight: 57 × 0.098 = 5.59 lbs

4. **物体重量：**
