HydroDome uses Nelson Big Gun 150 Series sprinklers mounted on 30ft towers to create humidity domes that protect structures from wildfire. Each tower covers ~1.54 ha (140m diameter) at 400 GPM, 100 PSI. Towers operate on duty cycling via Capstone C65 microturbine-powered zones. V21 fixes Buildings Protected display (replaced Harrison data with Fort St. James building grid - 118 structures - now shows actual coverage %), ember-only activation (zones spray when embers within 100m), strategic 16-tower layout (hospital SE coverage), ultra-slow fire (0.25x), organic geometry, force field protection. Click "Load Recommended Layout" for instant deployment showing 40-50% coverage. Water network from OpenStreetMap (409 Fort St. James roads).
