X-Message-Number: 20678 From: Date: Sat, 21 Dec 2002 16:31:59 EST Subject: correction --part1_105.22cd0b49.2b3637cf_boundary Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit I misspoke myself a bit in an earlier posting today--not that it's important. A thermopile is a stack of thermocouple-like devices in series, developing a potential difference or voltage when one side is warmer than the other. This depends on the Thomson effect, creation of an electric potential difference between two points in a conductor at different temperatures. The Peltier effect is the reverse; if a thermopile has the correct side inside a refrigerator and the other side outside, a current will cause the inside to become cooler.
