[Amps] HV switch-mode power supply

[David Cutter]

I operated from a refurbished 18th century water mill a couple of weeks ago. 
They are using an Archimedean screw generator to deliver 25kW from a quite 
small part of a small river with only 4ft or so drop.  That's the way to go 
if you are out in the Styx as we were.
