Clock of the Long Now - Installation Begins


“The Long Now is the recognition that the precise moment you’re in grows out of the past and is a seed for the future.”

                  – Brian Eno (founding board member of The Long Now Foundation)

After over a decade of design and fabrication, we have begun installing the first parts of the Clock of the Long Now on site in West Texas.  In this video you can see the first elements to be assembled underground, the drive weight, winder and main gearing.  This is the first of many stages to be installed, and we continue to fabricate parts for the rest of the Clock in several shops along the west coast.

The 10,000 Year Clock was conceived by Long Now co-founder Danny Hillis as an icon to long-term thinking, and the first prototype of the Clock now resides in the Science Museum in London.  This monument scale version, built in partnership with Long Now supporter Jeff Bezos, began with construction of the underground site itself, and is now moving into the installation phase.

This monument scale Clock is designed to run for ten millennia with minimal maintenance and interruption. The Clock is powered by mechanical energy harvested from the temperature difference from day to night, as well as the people that visit it. The primary materials used in the Clock are special grades of stainless steel, titanium and dry running ceramic ball bearings.

The Long Now Foundation was founded in 01996 as a non-profit dedicated to encouraging long-term thinking and responsibility. The 10,000 Year Clock is one of our many projects which include long-term data archiving, documenting endangered languages, and producing events and media that engage the long-term future. Long Now is entirely funded by donations and the support of more than 9000 members around the world. Find out more at

We would also like to thank the amazing people, partners, shops, and artisans that we have worked with over the years to make these parts and the underground site.  Without all their devoted efforts and attention to detail this work would not be possible.
