Hello! I've only just come across the Unruh Effect...so please bear with me! Say you have a long pole, and you spin the pole around its center. The ends of the pole would then be accelerating but the center of the pole wouldn't be. The Unruh Effect would seem to be saying the ends of the pole would experience a higher temperature than the center. What would happen if you could tap into this energy differential? Would it be available to do work? Imagine a long thermocouple...would it produce electric power?
