Can We Create Electricity While Cooling our Homes?

AI Thread Summary
Cooling homes with air conditioning consumes significant electricity, primarily due to the process of heat removal. While heat is a form of energy, current technologies do not effectively convert waste heat from cooling into electricity. Air conditioning systems function as heat pumps, moving heat rather than generating energy. The challenge lies in the need for efficient methods to reverse heat flow, which is not yet feasible. Thus, while the concept of generating electricity while cooling homes is intriguing, practical implementation remains a hurdle.

In the summer most of us turn on our air conditioning and we use lots of electricity in the process. But by cooling our home we're just taking heat out our homes. Heat is a form of energy. If we are taking heat away why are we also using electricity in the process? Can't we turn heat into electricty so that we are cooling our homes and creating electricity in the process?

A house isn't cooled by removing heat energy, such as if it were cooled by a heat sink of some sort. The air in a house is compressed, and this compression occurs at a cost of waste heat. Turning waste heat into electric energy isn't really a viable technology yet, is it?

Heat, like water, flows from high to low. To make it flow the other way, you need a pump. An air conditioner can be seen as a pump that moves heat instead of water.
 

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
