Thanks guys Then I take it that an Ion generator will make a
difference do you think this one will do
or should I look for something bigger http://store.qkits.com/moreinfo.cfm/QK57

I don't think an ion generator will make enough difference for the money.

Why not use an old crt monitor or tv as primary voltage source?

Sure that would work. The current output of the multiplier can be
increased by increasing the capacity of the caps - the diodes are
usually just loafing along at a few micro amps.

That ion generator is mains operated and only isolated from the power
mains by the caps - so be safe.

The voltage will increase but is still limited by the size and shape
of the collector. What increases more dramatically is the ability to
charge up again after a discharge (or the current output) and it will
compensate for some of the losses to corona and humidity.

The current output of the ion generator can be predicted based on the
cap size - probably from the capacitive reactance of the (series) caps
- but there are some sites with information on that if you search.

The excitation system for the machine can be built in many ways. There
is the original, and best, using an electronic excitator to spray
charge in the belt, and many other possibilities, that can be
identified with the charging systems of the classic friction and
influence machines. This picture shows some of the possibilities.
