Granted, this isn’t a perpetual motion machine, but it is expensive and pretty close, so there ya go! This Jaeger-LeCoultre Atmos clock will stand the test of time without ever losing a beat!
Just a quick thought, doesn’t this contradict the second law of thermodynamics? The one that states that all closed systems will succumb to entropy over time?
Anyway, science aside, this clock was created by Australian aircraft designer Marc Newson and it’s an Atmos clock, meaning that it’s powered by minuscule changes in temperature, which could mean that it could run for a very long time on basically nothing but air and at least 1 degree of temperature change (Celsius) every 2 days.
This limited-edition Atmos 566 clock is encased in a Baccarat crystal to make it just that much more special. There is also a sky chart in the middle, which will indicate the astronomical details of the sky in the Northern Hemisphere.
There will be only 48 of the clear models built and 28 of the blue crystals. They’ll set you back a large amount of money. How much? You’ll have to inquire for the price, but the cheapest and most basic Atmos clocks out there cost $2,600 (USD), and I imagine this one will be much more expensive. Yikes!
