[RFI] wireless power at 6.4 MHz?

[digital-conjurers at adelphia.net]

It sounds like a concept that needs to be followed up on and prototyped... over 40 years, one of my favorite curses, when piling through and unravelling bale upon mile of cabling, wiring, etc, has been, "Man will never be truly civilized until he learns how to conduct and direct power without wires!"

"Any energy not diverted into a gadget or appliance is simply reabsorbed." 

Hmmm...does this mean that this example at the URL below may not be rife with harmonics,  wide sidebands, etc, etc?...I just hope that when they build the production model, it doesn't have a bandwidth 2 Mhz+ wide, and it's shielded and bypassed properly.  Based on current manufacturer experience, my hope is small in this regard.  What comes out of the factory in China may not be as clean as what they envisioned in that lab.

But,  just maybe it will work without polluting the RF spectrum.  It's very interesting.  Something to watch.
