Default Bigger RFI threat than BPL, IBOC?

Greetings;

Thanks for bringing this to our attention. If the energy stays near the
coil, how would it interfere with HF? It would be interesting to learn more
about the science behind this research. It would be interesting to have a
shortwave radio at the lab and hear what happens.


This is a workable concept over a short distance; the shorter the
better. A practical example would be a induction stovetop where the pan
is right on the other side of a ceramic top from the induction coil.
Many people have these but a drawback is that you have to have iron,
copper or steel cookware. Glass or ceramic pots and pans won't work.

The idea is to put all the power into an induction field and not radiate
the energy to a greater distance than 1 wavelength of the operating
frequency. Energy in a local induction field does not leave the local
circuit. A local power induction field could easily cause a radio not to
function and even damage it.

This is not workable over the distance of a house. The power induction
field would have to saturate everything in the house including people.
Currents would flow in any conductor and heat it up.
