Stickman Adventure, Part 46: The Gear Room

Our hero dashes inside. Once his eyes adjust, he finds himself in a grand room of hewn grey stone or concrete, with immense gears mounted to one wall. There appears to be a missing gear and drive belt which would permit the other gears to turn what looks like an electrical turbine. There's a hole in the ceiling and another doorway in the far wall.

What would you have our hero do next?
