Reading "concerns about audio quality" and "intel" in one mail sure
raised
some interest here. Selling worse audio quality as the new high-definition is
probably one of their biggest successes.

Well, there _could_ be some interference as the air around you contains some

(a) heat up the water making the room you are in warmer (same principle as
the microwave) or (b) the water molecules move as they are electrical
dipoles. And moving molecules in the gas-phase are exactly what
sound/acoustic is...
But that is only a _very fast_ assumption without looking at the
aforementioned technology of intel.
After the latest Intel announcment that they are
indeed working
seriously on wireless electricity uses resonance to transmit hte energy
sources I am wondering if anyone has ideas on whether that would affect
audio quality as resonance is an important part of the ambience of live
sound.
Wireless energy transfer:
http://en.wikipedia.org/wiki/Wireless_energy_transfer
is acheived using electromagnetic resonant induction.
The resonance of live sound is acoustic resonance:
http://en.wikipedia.org/wiki/Acoustic_resonance
Since these two forms of resonance use different mechanisms
(electromagnetic waves vs sound waves in air) they do not cross
couple, hence there is zero chance for interference between them. The possibility of interference in electrical/computer
audio
equipment (which use electromagnetics) and the wireless electricity
transfer (which also uses electomagnetic waves) deserves far more
concern.
True! And don't forget the fact that others might pick up your energy and use
it without paying.
