Now, things may have changed since then. However, at that time, he was
confident in it (effectively) self running. If that still stands, it
would
make verifing his claims somewhat simpler...

Indeed it would!
The problem has been finding a low speed efficient generator. Jones
found a motor used on a Fisher & Paykel washing machine which is about
50% efficient at 90 RPM. The problem is that the voltage output is a
ramp since the torque is generated by a magnetic gradient. Here is a
plot of the output (open circuit) voltage when the generator is run by
the motor:

It is a permanent magnet, three phase rectified alternator output. It
is slightly clipped; so, it actually goes from almost 14 V to a peak
around 27 V.
If it does self-run, you'll see it on CNN! Do you get CNN in the UK?
