What Are the Size Limitations of Thermoelectric Generators?

AI Thread Summary
Thermoelectric generator modules face size limitations influenced by various scaling factors and physical constraints, such as atomic layers and gravity. Manufacturing challenges arise when Peltier elements are reduced to small sizes, complicating production processes. The smallest Peltier generators are produced by companies like Micropelt, where the thickness is primarily determined by the silicon substrate used. Overall, while there are no strict minimum thickness requirements, practical manufacturing issues impose significant constraints. Understanding these limitations is crucial for optimizing thermoelectric generator design.

it's a simple question:
is there any limitation to the size of an thermoelectric generator module?
is there any minimum thickness?
thank you in advance

Actually it is not a simple question... There are a number of values that scale with size, and at the far ends there are physical constraints like atomic layers or gravity. When you make Peltier elements small they become very hard to manufacture. These guys probably make the smallest Peltier generators out there: http://www.micropelt.com/products/products.php For those the thickness is dominated by the silicon substrate.
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
