Following an entropy approach, the electric current can be postulated as a flow of electromagnetic waves that has an electric potential. Such postulate is verified in this article by results of experimental measurement then it is applied to review Tesla’s discovery of wireless power transmission. Tesla discovered the wireless transmission of electric power during his operation in an entirely new domain of physics based on abrupt discharging of electrostatic charges. He realized that electrons were not responsible for such discovered phenomena. So, he called the new energy as “Radiant Electricity”. He didn’t identify that the true nature of electric current was a flow of electromagnetic waves that can be normally radiated through air. So, he proposed the term “Aether gas” to describe the discovered transfer of the electric charges by radiation from his designed tower, though air, to specified receivers. Following an entropy approach, the nature of the discovered radiated energy can be identified as electromagnetic waves that have an electric potential. So, the followed approach succeeds in eliminating the confusing observations of Tesla’s measurements in his famous experiment and the confusions found in modern literature that deals with such energy as an “Ambiguous Radiant Energy”.

Nikola Tesla is seen by mostly scientists as the “Father of Wireless Power Transmission” or the first person to conceive the idea of wireless power transmission and successfully demonstrated the transmission of electricity without wires as early as 1891 [

According to an entropy-approach and the similarity characterizing the heat flow and the flow of electric charges, such “Radiant Energy” can be postulated as a flow of electromagnetic waves that have an electric potential [

Starting from the similarity and analogy of laws governing the flow of heat and electricity, it was possible to postulate that such flows have the same nature [

plate that defines the known physical constants h and e [

The symbol “e” in Equation (1) indicates the charge of the reflected photons. As seen in

Similar proof can be concluded according to the measurement results of light emitting diodes [

In Equation (2), “” is the speed of light and “λ” is the wavelength of the emitted light in meters. The measured slope of the curve in

According to the measurement results in _{0}” that led to emit light from such diode [

ionized electromagnetic waves finds also a plausible explanation for the processes in the diodes and the photocells. Equations (1) and (2) can be simplified by one proportionality equation as follows [16,17]:

According to such results, the potential of the electric current as flow of electromagnetic waves depends on the frequency or the energy of such waves. So, the following equation may express the output current from a photocell or the incident current in a diode [

where E is the potential of the oscillating wave around and is the threshold potential. Such equation can be considered as a solution of the Maxwell’s wave equations that belongs to the electric component of the electromagnetic wave [

The arrow of time is found as a property of entropy alone [

Such equation can be represented in graphically in the E-s coordinates as shown in

By similarity between the electric charge and heat flow as both are forms of electromagnetic waves and are driven by their associated potentials E or T, the flow of electric charge can be expressed also by areas in an E-s diagram according to the following equation [

According to

According to the previous entropy approach, the accumulation of electric charges that possess electrical potentials on the top surface of the Tesla’s tower [

is the potential of each charge which was defined as the thresholds’ potential, N is the number of accumulated charges on the top of the tower and E_{tower} is the potential of the accumulated charges on the top of the tower. When such high potential energy is discharged as electromagnetic waves, it will produce the measured shock wave in a similar fashion as the discharged of clouds [

So, the energy transmitted from the tower to the receiver is a flow of entropy by force of the tower’s potential and can be estimated according to the following equation:

However, the loss of the transmitted electric energy from the tower to the end receivers, , is dissipated to the air in the form of thermal energy. The dissipated energycan be estimated by applying an energy equation that embraces the flow of electric and thermal energy [

So, the lost electric charge will be gained by air as thermal energy that will increase the air temperature. If the attained temperature is high enough, it may ignite atmospheric nitrogen in presence of atmospheric oxygen according to the following chemical equations [

Similar reactions are found in thunder storms during discharge of clouds [

Such conclusions violate the definition of electricity as flow of electrons that requires conducting wires and sustains its postulated definition as a flow of electromagnetic waves [

According to the previously discussed measurement results of photocells and diodes, the wavelengths of the

ionized electromagnetic waves that define a flow of electric charges are in the range of 650 - 1500 µm [

It is an interesting remark of Tesla that he had never referred to “space-time” directly. He considered time scale or dimension as a mere man-made “measure” of the rate at which events may occur such as a distance travelled in a certain period of time, for a frame of reference. He tried to find another frame of reference that ties such the space to the system’s energy but he didn’t find a logical substitute [

According to an entropy approach and a review of available experimental results, the flow of electricity is realized as flow of electromagnetic waves that have an electric potential. So, Tesla’s discovery of “Radiant energy” should be also interpreted as normal radiation of electromagnetic waves that have an electric potential. Replacing the time coordinate in Maxwell’s wave-equations by entropy, the discovered “Radiant Energy” of Tesla is also found as a flow of entropy by the influence of its electric potential. Such radiant energy is also found as a dark energy or electromagnetic waves whose wave lengths are not in the visible spectrum.
