[Amps] SS amps watercooling - was PowerGenius XL

[Roger (K8RI) on TT]

Wouldn't Amps, or Ham Amps be a better reflector for this thread?

Were talking distilled water here. If it's conductive enough to present 
a danger, it's long past time for a replacement.

When I was a Tech (before going back to college) it was rare to have 
water spraying around inside those 100, 200, and even 250 KW generators 
and the load coils were exposed.

Water cooling is a simple, mature technology.  Water cooling is rather 
simple. It's the monitoring that can get complicated.  In high voltage 
areas, we used linear (solenoid) coils of clear Tygon tubing to get the 
necessary high resistance.

The simplest was a clear plastic block, drilled and tapped for all the 
water exhausts.  You could see at a glance  how well any water circuit 
was doing.  Simple, cheap, and foolproof "IF THE OPERATOR PAID ATTENTION".
