I am going to offer an explanation, and this explanation destroys the Inverse Square Law (ISL) argument being used against the PERL by some of your competitors.  Perhaps after hearing my explanation, the ISL can be used to contrast those devices whose operation are subject to this law. All devices that are subject to the law have to be used within a few inches of the body to produce best effects. Not 30 feet like the PERL!

There are two key aspects to this explanation.

First, the body is an antenna and will actually produce a “gain” to the signal strength via a natural resonance. The best resonant gain is at around 50 MHz, but there is still a very good resonance gain at 27 MHz as well.

This brings up a point, a human body’s resonance and gain at 3.3 MHz is relatively very poor compared to the resonance and gain at 27.125 MHz. Due to poor resonance and little to no gain, devices with a 3.3 MHz carrier are subject to the Inverse Square Law and must be used close to the body to maximize delivery of frequencies. The manufacturers in fact recommend their customers use the devices very close (within inches) to the body.

Further the first harmonic of 27.125 MHz is 54.25 MHz; a harmonic of the carrier wave that the PERL produces. This carrier harmonic includes sidebands and this is right at the peak of body absorption.

Second, the human body is a capacitor – why one can walk across a carpet and get a shock by touching a door knob. Capacitors of course store energy. In the case of the just mentioned sparking/shock a human body can store thousands of volts of energy !

This all brings us to the method, a subset of what is known as Wireless Resonant Energy Transfer (WRET). WRET is currently used to charge different electrical devices especially cell phones , with the device being in proximity to the field of the charging device. Most of the commercial devices using WRET use magnetic fields to transfer energy wirelessly via induction. Induction works only across a small distance and is also subject to the Inverse Square Law. This is where things get all confused. The PERL does not use Resonant Induction to transfer energy.

As is known, the plasma tube converts RF into an intense Oscillating Electric Field. The wavelength of 27.125 MHz is 35.6 feet . This is important, for the effective distance of the PERL is dependent upon the wavelength of the carrier wave. As the body can act like a capacitor and also is very resonant at 27 MHz, the PERL transmits energy to the human body via what is known as Resonant Capacitive Coupling.

From Wikipedia on Wireless Power Transfer:

Near-field or nonradiative region – This means the area within about 1 wavelength (λ) of the antenna. In this region the oscillating electric and magnetic fields are separate and power can be transferred via electric fields by capacitive coupling.

Here is a video showing the use of a 9V battery and 0.1 ampere of current to light an LED array at 30 cm distance using Resonant Capacitive Coupling. This is an impossibility from the concept of the ISL and even via inductive coupling.

”Please note that this is the method Nikolai Tesla sought to utilize in his World Wireless Energy System.”

Bottom line, just like Tesla, the PERL uses Resonant Capacitive Coupling. Due to its 27.125 MHz carrier wave can be effective at distances up to 30 feet . It accomplishes this via Oscillating Pulsed Electrical Fields (OPEF) emitted by the plasma tube. These fields being pulsed, are then Capacitively Coupled to the body and resonantly absorbed in the form of frequencies to produce physiologic effects at a distance. The Inverse Square Law does not apply !

This is a hugely significant discovery and makes the PERL stand unique among all other frequency devices.
