     Hmmm, obviously i need to do some more research on this.  It hadn't 
     occured to me that I would need to evacuate the "ball", and thus need 
     one that could stand the pressure.  I have seen some amazingly strong 
     geodesic domes built from steel pipe but the engineering is sounding 
     formidable.
     
     Could you explain what you mean by shunt capacitance?
     
     Thanks for your comments,

The insulation which works at normal atmospheric pressure would be 
*gone*. However, the voltages at which these things work is 
nowhere near typical TC voltages. What I found was needed for the 
ball I fixed (it ran CW from an inverter) was a lot of power. The 
shunt capacitance it presented to the power supply was very high. 
You would have to take this into account when considering the use 
of a TC. In fact, you'd really need to know the range of values under 
different streamer conditions before you even started designing a 
TC to run it.
