Another idea I just had is perhaps having someone with a ceramics oven
paint on the endcaps with ceramic glaze. It would look like a giant
ceramic resistor! But then again, I would guess that as the resistor
heated up, it would crack. Never mind...
I'd guess the high heat used to fire ceramics would simply cause the
carbon to burn up.
In the Navy, the shipyards all have a device called a Load Bank. It's
a
large metal tank on an insulated vehicle. The tank is filled up with
salt water and electrodes lowered into it to test the output of the
ship's
generators. Any chance that it has ham applications? I intend to try
it
first with an antenna analyzer and then, if it looks promising, my rig.
Yes they did the same with transmitters, often all you need was a
metal mop bucket and a piece of copper pipe

A water load bank is good for hundreds of KW at 60hz.
For use with a pair of 6146's we used to wire a lamp to a coax
connector. We had a load as well as visual indication of the relative
power output.
