Im thinking that the color of the light of the harvester might be interfering with the RF transmitted from the phone have there been any test to see if it is the light on the harvester that is causing the other harvesters to not
light up ...
wire the lights away from the circle or block the light
so that the harvester light can not interfere with the RF
signal.
just pickin a straw.
In the proper lab we don't use the home sort of harvester we use atoms to do the absorbing. The usual is pentacene (
https://en.wikipedia.org/wiki/Pentacene) which has a nice exciton emission you can easily detect.
So we convert the emission directly to an electrical signal.
We do eliminate that sort of thing and it still behaves the same.
Oh now you understand what was happening you will probably be able to understand what a maser is and why it works like a laser.
Contemporary masers can be designed to generate electromagnetic waves at not only microwave frequencies but also radio and infrared frequencies
You will also get why and how it works across all those frequencies now and confirmation the effect is real at a micro level. Basically you control which atoms are likely to see an emission and by doing so build a population inversion for the stimulated emission which you output for use. There are some designs that don't work like this they use different mechanisms but it is the most common way to do it.
