Agree

Aaron,

On MIT experiment, I agree with you. I believe the authors.

Quote:
Although the Peltier heat exchange of the injection process is highly nonuniform, on average the device remains very slightly cooled so that in steady state the thermal energy required to pump the emitter flows in from the ambient environment. The net cooling power Pcool is given by the difference between the emitted optical power and the input electrical power and is shown in Fig. 4(a).
Ambient energy enters the device and contributes to the output or useful work done, making the COP 2.33. I say this clearly before, and now. I am sincere.
