No, you just need to use resonance, though I grant that a resonant circuit at 50
or 60 Hz would probably need large

Regarding the charging, if you shift the source band up-spectrum to light
frequencies, then all that's needed is a photocell and a small IC for
voltage boost. Probably get more charge too, even if the phone is

If they extended the range to below 50Hz, they could pick up the stray
field
from the grid, which is much larger than the RF transmissions they are
harvesting now. Since most of this would be harvested indoors, it would
automatically be
