Solid State Devices: Harnessing Heat to Create Electrical Energy

AI Thread Summary
Solid state devices, specifically Peltier junctions, can convert temperature differences into electrical energy, utilizing the Seebeck effect. These devices consist of two metal plates with a thermoelectric material sandwiched between them, generating current when one side is heated and the other remains cooler. The discussion highlights the ease of energy extraction from thermal imbalances, aligning with the second law of thermodynamics. For further understanding, resources like Wikipedia provide detailed explanations of the thermoelectric effect. This technology exemplifies how heat can be harnessed for electrical energy generation without any moving parts.

Last summer I spent a few days at RIT taking some seminars on engineering and what different courses would be like, one of the professors was demonstrating some of the materials we would get to use and he produced a an object consiting of two metal plates sandwiching some other sort of material with two wires leading out of it. He then demonstrated that if you apply heat to one side and a relativly colder object to the other, you could get a current running through the wires. He called this a solid state device because it had no moving parts inside.

I understand that it is easy to get energy from an imbalance such as the temperature imbalance between the plates (I believe that's the 2nd law of thermodynamics). But if someone could explain the innerworkings of this device like how it turns the heat into electrical energy, or any other information on these devices, that would be most appreciated.

It is a peltier junction. I'm sure you can find all kinds of info if you google it and perhaps check wiki.
 
Look up the thermoelectric effect and more specifically, the Seebeck effect.
 
Thread 'Where is my curb stop?'
My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...
