Endothermic reactions converted heat energy as electricity?

AI Thread Summary
Endothermic reactions typically absorb heat rather than release it, making them unsuitable for generating electricity directly. The discussion explores the potential of converting heat energy from endothermic processes into electricity, particularly at low temperatures. Thermoelectric cells can utilize heat from sources like radiators to produce electricity, but their efficiency is limited. The concept of a personal power generator that operates at refrigerator temperatures is intriguing but faces significant practical challenges. Overall, while there are methods to convert heat to electricity, endothermic reactions are not a viable source for this purpose.

Are there any endothermic reactions that can release the converted heat energy as electricty? How do they work?

I wonder if it is possible to create something that will convert heat to electricty all the way down to refridgerator temps... they you got your personal power generator and a fridge! :smile:

Are you talking about chemical reactions? I doubt it very much.

As far as physical processes are concerned, you could use the heat coming off the radiator to run a thermoelectric cell, but it wouldn't be very efficient.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
