An anonymous reader quotes a report from CNET: Amazon CEO Jeff Bezos shared a video on Tuesday of his latest project: a giant clock designed to keep time for 10,000 years. Buried deep in a west Texas mountain, the project is in partnership with San Francisco-based group The Long Now Foundation, which grew out of an idea for a 10,000 year clock that co-founder Danny Hillis proposed back in the '90s. Now, the 500-foot tall mechanical wonder is finally undergoing installation. Bezos is fronting the cash for the $42 million project, saying on the project's website that the clock is "designed to be a symbol, an icon for long-term thinking." The clock is powered by a large weight hanging on a gear, built out of materials durable enough to keep time for 10 millennia. Bezos isn't the only noteworthy name on the clock project. Musician Brian Eno and writers Kevin Kelly and Stewart Brand are also involved in the clock's construction. The team has spent the last few years creating parts for the clock and drilling through the mountain to store the pieces. You can read Bezos's account of that and view photos of the progress here.
