Brick Technology - Making A Billion-Year Lego Clock
Ben Wow ! Enfin si le plastique résiste =)
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, mega-annums and galactical years (time required for the Sun to orbit once around the centre of the Milky Way Galaxy).
Le système de poids:
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 panel is mounted on a tilting mechanism that is connected to the 24h complication, following the sun during daytime.
