Moviemiento

Moviemiento's bicycle cinema is the KLAK-derived system: ten spectator bikes generate the electricity for projector, laptop and sound system, advertised by the operator as "100% self-sufficient". For the 2018 tour Moviemiento partnered with KLAK's authors, UfU e.V. and Solare Zukunft e.V., and curated an international short-film programme, "Von Drahteselträumen und reisendem Glück", that visited sixteen German cities over a summer with a day-long supporting programme at each stop. From 2019 it ran its own events on the same architecture — an Earth Hour screening in front of Berlin's Brandenburg Gate, WWF Germany's Change Days, short films projected onto the sail of the ship Hawila in Lübeck harbour, the Chaos Communication Congress in Leipzig, and a short autumn 2019 tour through Rostock, Leipzig and Dresden that closed in Berlin. No generator rating, buffer capacity or projector wattage specific to the Berlin and Freiburg units is published; the architecture is documented through the KLAK manual.

In their own words

"Beim Fahrradkino wird der Strom für das Kino selbst produziert. Dabei sitzen zehn Zuschauer*innen auf Fahrrädern und erstrampeln die Energie für Sound und Bild." — In the bicycle cinema, the electricity for the cinema is produced by the audience itself. Ten spectators sit on bicycles and pedal the energy for sound and image. ²

Corrections and confidence notes

The "100% self-sufficient" description is Moviemiento's own wording ³; no instrumented figure for either unit has been located, and the same KLAK architecture drew on its buffer battery at a documented Karlsruhe school event when riders rotated inconsistently. An earlier directory label of "uncertain", given because no dated activity after 2023 had been found, was superseded when the booking page was found live and bookable on 9 September 2026 ³.
