[Server-devel] 12 Volt power system for School Servers.

[David Farning]

The piece I am looking at is reducing the losses between the battery and
the server/AP.

Several systems have a 12V Battery which is inverted to 120AC which is then
transformed back to low voltage DC for input to the server/AP. That doesn't
seem very efficient.
