Greetings,
The device functions as a heat pump; it doesn’t produce energy so much as move it from one place to another.
This post discusses the specifications for this type of device in some detail.
When it comes to thermoelectric modules of this sort, if one’s asking the question the answer is almost always “no.” It’s a tricky subject to pick up on if one hasn’t taken a thermodynamics course or two.
Beyond that, the devices are so horribly, awfully, wretchedly inefficient that a people who don’t take time to run the numbers are almost always disappointed with the results of a “try it and see” design approach.
