Human intervention to activate the dials and wind the chimes, but the timekeeping is good for 10000 years (they went for daily temperature changes as well as the pendulum.) From http://www.kk.org/thetechnium/archives/2011/06/the_clock_in_th.php http://www.kk.org/thetechnium/archives/2011/06/the_clock_in_...: So how does the Clock keep going if no one visits it for months, or years, or perhaps decades? If it is let to run down between visits, who would keep resetting it? The Clock is designed to run for 10,000 years even if no one ever visits (although it would not display the correct time till someone visited). If there is no attention for long periods of time the Clock uses the energy captured by changes in the temperature between day and night on the mountain top above to power its time-keeping apparatus. In a place like a top of a mountain, this diurnal difference of tens of degrees in temperature is significant and thus powerful. Thermal power has been used for small mantel clocks before, but it has not been done before at this scale. The differential power is transmitted to the interior of the Clock by long metal rods. As long as the sun shines and night comes, the Clock can keep time itself, without human help. But it can’t ring its chimes for long by itself, or show the time it knows, so it needs human visitors.
