China, Taiwan, Japan and Korea

The Chinese network was state infrastructure rather than an operator: bicycle-frame pedal generators paired with the China-specific 8.75 mm projector were standardized wherever villages lacked electricity; county gazetteers put the rollout on record as policy — Qimen County's first commune film team from 1970, Yichuan County's fourteen units from 1971 — and a working unit was demonstrated at a Sichuan university museum as recently as 2025 ^1,2,3,4. The system was live-wire, with screen brightness tracking pedalling speed directly and no buffer of any kind, and rural electrification ended the practice ^1,2,3,4. The region's technical reference is academic: a 2016 Wuhan University study measured about 58% generation efficiency against a 58.2 W projector load ⁵.

The later entries are events rather than organizations, with both buffered and live-wire systems among them. Taiwan's one modern event was the Society of Wilderness's Earth Hour "starlight cinema" in Taipei on 28 March 2015, in which twelve generator bikes charged batteries in a nine-hour public relay for an evening screening; the promoted 25 kWh harvest target was never measured or disclosed ^6,7. Okayama's Hyakumori Denki village festival exhausted its battery one minute before a film's end in 2023 and finished by live pedalling ⁸, while the Nara International Film Festival's recurring bicycle-generator screening runs on the live-wire premise that if you don't pedal, the film stops ⁹. Korea's two records are Incheon Green Federation's 2008 Earth Day bike-generator screening and the Bukhansan Environmental Film Festival's pedal self-generation in 2017 ^10,11. The British Embassy unveiled a UK-built pedal-cinema unit for off-grid Lao villages in December 2013; Laos sits in this region for want of a Southeast Asia page ¹².
