Abstract
This document describes a small, distributed, self-sustaining power generation node (hereafter "Block Station") designed for cold-climate communities (operating range: -40°F to +100°F / -40°C to +38°C) where centralized grid infrastructure is unreliable, damaged, or absent. Each unit combines a hybrid Savonius-Darrieus vertical axis wind turbine (VAWT) with integrated snow capture, a 400W solar array, a 1.28 kWh LiFePO4 battery bank, and a 4-slot community battery charging system with RFID-based user identification and per-user limits. Units are placed adjacent to existing structures, require no grid connection, and are monitored by mobile vehicle operators on scheduled routes. The design prioritizes: (1) omnidirectional wind capture with self-starting at 3 mph, (2) passive snow management that converts snowfall into minor torque augmentation and self-clears via gravitational dump, (3) minimal thermal overhead (40W average enclosure heating), (4) low cost (~$1,600/unit with repurposed materials), (5) high survivability against kinetic and environmental threats due to small physical footprint and distributed deployment, and (6) full buildability from locally available or repurposed materials. A 1:4 scale prototype build procedure is included. All specifications, calculations, BOMs, and firmware logic are provided in full. This document is released into the public domain.
