You point out one the more interesting aspects to all of this... the ability
to measure what's really going on... I sell robotic lawn mowers that use a
energized wire to creat a magnetic field for the electronics of the mower to
respond to... when I went out to get a magnetometer to measure the fields
the wires are producing I found such equipment difficult to come by... the
probes imprecise... the strength of the background field of the earth a
mitigating factor

The instruments are better now, but measuring a magnetic field, it's
orientation, it's strength and so forth is still pretty imprecise... a true
measure of the field in the core would require an internal probe... right
now we (you, I and all the others trying to reproduce this effect) are
actually guessing... once we enter the realm of guessing we are into the
"black arts"... strangely I feel a kinship with Edison when I consider the
challenges here... Bearden's team has an irreplaced pool of empirical
knowledge we collectively must accumulate...
I believe we are on the road...
