The Clock of the Long Now , designed by Daniel Hillis and the Long Now Foundation, is a clock designed to run accurately without interruption and maintenance for 10,000 years. Find out more about how it works here and here and here . Consider: The half-life of enriched uranium (Uranium-235) is 704 million years. That of depleted uranium (Uranium-238) is 4.5 billion years. All of the nuclear waste that has ever been created by humans--that continues to be created at a rate of over 3,000 tons per year in the US alone--will continue to exist and be deadly for longer than the life of the sun. The Waste Isolation Pilot Plant (above) is a storage facility in southeastern New Mexico designed to "safely" store nuclear waste. This site is only for "so called low- and midlevel waste," but its contents, many thousands of tons of contaminated clothing, building materials, and equipment, are and will remain poisonous beyond any future we can image (Weisman).
