"Gravity powered" pendulum clock

It ticks! Power is stored in the big weight on the left side of the chain, and as it falls, it slowly releases its potential energy via a pendulum escapement mechanism. To add energy back into the system without intterupting the power output, it uses a "Huygen chain drive" configuration. By rotating the centermost pulley, the weight ascends back up while still providing the same constant "pulling force" on the escapement mechanism. TL/DR: Just press "T" when the big shiny thing is low, then press "T" again when the big shiny thing isnt low anymore. :) -Slitex
