Last night's second guest was a hoot. He was talking about his new device, the Soulphone, that enables those of us still living to communicate effectively with the deceased. While the guy claimed to have several degrees, including those in clinical psychology, theological/pastoral counseling, and chiropractic medicine, he seemed to lack an understanding of basic engineering design and test.
George asked the guest to describe the device. He hemmed and hawed a bit, then explained it was in a plexiglass enclosure that is "impervious to EMF, humidity and temperature changes, vibration, and other outside factors."
While any competent test engineer can design a fixture to damp out vibrations/shock, I'm skeptic about the other
claims.
Relative to EMF, he's basically talking about a Faraday cage. I'm not a EE, but my understanding is a Faraday cage must be made of a conductive material, usually metal. If no electrical signals can get in or out of the enclosure, how are the deceased and loved ones communicating?
As for heat and humidity, the enclosure will eventually take on the ambient temperature and humidity of its surroundings, unless there are heating/cooling/humidifing/dehumidifing units within the enclosure regulating temperature/humidity. Easy to do, but not without generating EMF. So if the box acts as a Faraday cage, is all that EMF trapped in the box? Or I suppose those units could be physically outside the enclosure and blow in/suck out heat and humidity, but that would make it far more difficult to transport. The whole unit is only 12"x12"x9" according to the guest.
To be fair to the guest, he did say on a couple occasions he didn't want to release too many technical details, so may be be far more here than what he was telling us.
