Perpetual Motion Patent Examiner: Judge the Machines That Never Stop

A 20–⁠25 minute story game: as a new patent examiner, run six perpetual motion inventions on a test bench (an overbalanced wheel, a recirculating mill, a magnet ramp, a ship run on ocean heat, a drinking bird and a self-charging electric car), balance each energy ledger, then judge it with an evidence card and a stamp.
