A harmonic tide drives channel flow through a real turbine power curve while floating homes bob on buoyancy physics tied to the same tide.
Turbine power follows P = ½ρAsweptv³Cp (seawater ρ=1025 kg/m³, Betz-limited Cp≈0.45, cut-in 0.3 m/s). Flow velocity is the tidal-gradient current v = k·A·ω·cos(ωt) through the constriction. Each floating home follows a spring–damper buoyancy response to the same tide height. Drag to orbit the camera, scroll or pinch to zoom.
