Ok. Let's change a little bit the problem. We have 2 reservoirs with delta T. If we will use a carnot engine or stirling engine which use as source of energy the delta T, we can produce work. But if we combine the two fluids, we don't obtain nothing. Or? Some radiations are emitted when we...

Ok, understood. You are right, the resulted recombined water will be warmer for a classic Whater dispenser. But, let's say that a warmer dispenser is in equilibrium(It will output 1L of cold water (0 degree) and 1L of warm water (50 degree). It will spend energy for making this. Right? And when...

Let's consider a water dispenser which use as input water at room temperature and the electrical energy to make the water cold and on the other side, hot. If you combine the cold and the heated water to obtain the water at the room temperature again, in which the electrical energy transform...

One of the point view, the electrons will have a bigger mass when the conductor is moving with speeds comparable with c, that could affect the conductivity. Is this point of view correct, taking in consideration the Einstein relativity theory?

Is the conductivity affected by the speed? Let's suppose that one linear conductor is going with c/2 speed which it's axis indicate the direction of speed. What will be the conductivity of this conductor in this case? The conductor will behave as an semiconductor? Marius
