Well-meaning people periodically 'discover' Peltier elements as an alternative to vapor-compression refrigeration with the regularity of a predictable cycle, suggesting a persistent misconception that devices with no moving parts are inherently superior to mechanical systems despite opposite efficiency reality.

Evidence Quote
