I do not see how this would be any different from powering a Seebeck
calorimeter, which is essentially a collection of thermoelectric devices
that capture as much heat as possible from the sample.

It's obviously different in terms of stagecraft.
However, LED's require several volts to light, even though they are the most
efficient light source known. Converting heat to electricity via the
thermoelectric effect is a very inefficient process unless you are using
PowerChips, which are new and iffy. What Harry is not considering is that
the volrage across a thermoelectric junction is small, so many junctions
would be needed in series. Furthermore, the LED's will respond to the total
heat released in the cell, not the "excess heat" which is critical. As Jed
points out, the Seeback calorimeter is a precision quantitative device, and
the LED's are not. So, the LEDs would prove nothing to a knowledgeable
observer.
