Making A Billion Year Lego Clock

Building a mechanical Lego clock that keeps time for 10000000 years. The clock has dials to display seconds, minutes, hours, days, weeks, months, years, decades, centuries, millenia, megaannums and galactical years (time required for the Sun to orbit once around the centre of the Milky Way Galaxy). The first component resembles a grandfather clock with a weightdriven pendulum anchor escapement. The escapement wheel rotates 1 tooth per second. Different gear trains transmit motion from the escapement to all complications from days to years to decades. As soon as the weight touches the ground, a rewinding motor is triggered to raise the weight and recharge the clock. This happens every 2 minutes. A solar powered battery fuels the energy storage for the electric rewind motor. Under a cloudless sky the solar panel generates more energy than consumed by the Lego pendulum clock. A bigger energy storage could be added to run the clock at night time. To increase solar panel efficiency the solar pan
