As was pointed out by more than one member, there is a severe signal to noise ratio problem with the thermal energy theory.
A good analogy to this signal to noise problem might be: "It's as easy as hearing the sound of a pin dropping on the floor of a concert stage next to the drummer playing for a heavy metal band, from 20 meters distance".

S/N ratios are The Issue with any detection system.
By your standards we shouldn't, couldn't, wouldn't, detect the Rx signal from a Pi MD on a Sunny day:
say 100mV in a 5 Ohm coil = 0.002W
Combined solar EM radiations/mxm = 750 W
S/N Ratio = 2.667 x e-6 = 0.000002667
Did I just hear... a pin drop?
I say, "Be Discriminating, Focus attention on the signals...they are not the same as the noises."
LRL - If it was Easy...everyone would be doing it!
