Re:Energy conversion devices (Score 1)

In physics (in fact coming up in the next physical science class is a topic on energy) there is a demo put out by Pasco that converts the difference between hot and cold into electric current. This is called the Peltier Effect, nothing new. In fact the solid state module can be bought from Marlin P. Jones (http://www.mpja.com) and Associates. This module is also the ones used for solid state cooling of a CPU. This works both ways to heat or cool depending on which side of the module you use (depending on the polarity of the current, one side heats the other cools) it will heat or cool. By the same token the same module can be heated on one side and cooled (Ice water works best) and it produces a current. I mean really this is not new.
