It is _very_ unlikely capacitively coupled to _anything_. As people pointed out, the foil does not conduct anything to anywhere. I give it less than 1e-99 % chance that it works for most of us. However, for people who believe the aliens gave IC technology to Intel so Andy Groves can let Bill Gates make billions (Gates is really an Alien from dark-star called Yuaranut), this foil will work just fine. The foil, afterall, was designed by even more advanced aliens who gave Qualcomm (Jacobs is also an Alien, but from an alternate universe called Beeghaepmaecheen) the CDMA technology! Then they got dissatisfied with QCOM management and went to Nokia (Finland? isn't that in Buulcheet star system?), but I digress...
