🎨 STEAM Project — Thread 1 Solar Geometry: Sovereign Solar Food Dehydrator — build a passive solar dehydrator from local materials, calculate the optimal collector angle for your latitude (θ = φ + 15°), document the build, dry food off-grid. Field guide included.
🧩 STEAM Project — Thread 3 Analog Logic & Algorithms: The Fluid Logic Computer — wire PVC pipe and ball valves into AND/OR logic gates; open and close valves to watch Boolean logic flow as water. One weekend, no electricity.
⚙ STEAM Project — Thread 4 Mechanics & the Physics of Work: The Gravity-Powered Kinetic Battery — lift a weight, store energy as PE = mgh, release through gears to drive a small load — same equation as grid-scale pumped-storage hydropower.
🌱 STEAM Project — Thread 5 Seed Sovereignty & the Living Engine: The Living Jar — Lacto-Fermentation — salt selects for Lactobacillus on fresh vegetables; pH drops from 6 to 3.1–3.7; self-preserving food, no refrigeration. 1–2 weeks.
