TECH - 10,000 Year, Subterranean Clock Will Transform Our View of Time and Technology

Powered By Mechanical Solar Energy. Engineered to Last. Designed to Provoke. Located deep in a mountain in West Texas.
There is a Clock ringing deep inside a mountain. It is a huge Clock, hundreds of feet tall, designed to tick for 10,000 years. Every once in a while the bells of this buried Clock play a melody. Each time the chimes ring, it’s a melody the Clock has never played before. The Clock’s chimes have been programmed to not repeat themselves for 10,000 years. Most times the Clock rings when a visitor has wound it, but the Clock hoards energy from a different source and occasionally it will ring itself when no one is around to hear it.
