The inner day and night globe simultaneously spins over two different axes,
one corresponding with the traveling of Earth around the Sun and the other
corresponds with the rotation of the Earth over its own axis. The
combination of both spins results in a replica of the apparent motion of the
sunlight over the surface of the Earth, therefore the pass of day and night
can be constantly seen from the exterior of the earth globe just as it is
seen from outer space.
The Globe Clock uses two different stepper motors controlled by
electronics to drive the unique mechanism that makes the magic happen.
The Globe Clock is powered with two replaceable AA batteries that
last approximately fourteen months. A graphic of the sun is printed at
the center of the day on the inner globe, so The Globe Clock is able
to display the current position of the sun exactly where the sunrays are
vertically falling on the Earth. By crossing its
inverse-analemma-sinusoidal-traveling-curves with the equatorial line, The
Globe Clock shows current standard time at the equatorial time zone
dial while coordinating this time with the actual position of the Sun.
The current date can be read through the Arctic Circle translucent window,
where an arrow continuously points out the current date. While you see
the nights and days pass, you can also see the hours passing by the time
zones. The designer strategically selected 12:00 PM, 6:00 PM, 12:00
AM, and 6:00 AM to rotate on the inner globe, so when one of these hours
passes under the center of a time zone it means this is the time on this
The Globe Clock you can easily understand the significance of the
polar circles and tropic lines along with the meaning of solstices and
equinoxes. The effect of six months of sunlight and six months of
darkness at the poles is clearly displayed, and the time of sunrise or
sunset at any place on earth can be forecasted and seen while happening.
The dream of constantly experiencing the pass of years, days and
nights over the earth on a physical model vs. a virtual model is now
successfully realized, and very complex concepts are simplified in an
elegant time piece, The Globe Clock.
