Exploring the Mystery of Heat to Current Transformation

[cala]

Hi all.

Imagine one negative charged dielectric rod into a copper solenoid, and rounded coaxially by another positive charged dielectric. Then we have an E field radially directed passing through the coil.

Now put one magnet on top of the coil and another magnet at the bottom of the coil, so we have a B field axially directed passing through the coil.

The copper coil has electrons inside, and these electrons are not static ones, they have random movements due to ambient heat.

Now, by virtue of the crossed B and E fields, these electrons will tend to flow with a preferred direction on the coil.

The E and B fields doesn't increase nor decrease the kinetic energy of the electrons of the coil, but changes direction in a perpendicular force fashion, so no work is added or needed. The resultant effect is "focusing" the random kinetic energy of the electrons to flow on a preferred direction, so we can add all the randomly directed kinetic energy into one preferred direction, and thus a useful kinetic energy appear from zero kinetic energy net resultant.

Now, if we put a load on the coil ends, the electrons will flow. The load will convert the ordered flow of electrons into random kinetic movements, so power is dissipated again as heat.

Then, the heat of the environment will go again into the device, because the ordenation of the electrons by E and B fields convert "heat" random movements of the electrons of the coil into kinetic useful work, so the coil goes cold...

So there are an electric cycle and a heat cycle.

The device transforms heat into current, (then the device goes cold), and then the load transforms current into heat, and finally the device takes that ambient heat.

What's the problem with that?

The physical principle of the device is well known.
Take a look to this page:

(if it doesn't work, type:www3.ltu.edu/~s_schneider/physlets/main/cross_eb.shtml)

you can play with the values, and realyze that it doesn't matter the initial direction of the charges, they finally follow the same direction (so finally, in a properly designed device, charges could create a current or voltage).

This page talks about the same. I think i have posted it before, but take a look:

There are a few potential issues with this concept. First, it is important to note that the E and B fields described in this scenario are not constant, but rather are changing due to the presence of the magnets and the movement of the electrons. This means that the device would need a constant supply of energy to maintain the fields and continue the cycle, which would likely come from an external source.

Additionally, the efficiency of this device would likely be very low. Converting heat into current requires a significant amount of energy, and the process of converting current back into heat also results in energy loss. This means that the amount of useful work generated by this device would be minimal compared to the amount of energy put into it.

Furthermore, this concept also violates the laws of thermodynamics. The first law states that energy cannot be created or destroyed, only transformed from one form to another. In this scenario, it appears that energy is being created from nothing, which is not possible.

Overall, while this idea may seem intriguing, it is not a feasible or efficient way to transform heat into current. There are more practical and efficient methods available for this purpose.
