The author even talks in one of the articles about one military base in the
area having a large (tesla?) coil.
The noise of the ring was like a Diesel locomotive. One thing you could
try with the smaller rings could be to tape the noise (if any) that they
make in a sound proof room. Don't know if that would lead to anything
except showing a possible link between the two phenomenon.
Just as a side note, has anyone progressed from smoke, onto high energy
plasma or EM like rings?
