Estimates of
conductivity ranged from 2 to 6 x 10-13
mhos/m. Actual measurements of conductivity
ranged from 0.4 to 1.8 x 10-14
mhos/m. The agreement is not very
good. This idea didn't quite pan out.
The researchers that conducted the experiment
concluded the estimates of conductivity "will be
extremely sensitive to small time variations in
the local Maxwell current density and must be
modified to include these terms".
