Re: [T3] 42 Volts (a bit long)

["Tom Hansen" <DrSoWatt@worldnet.att.net>]

Aircraft  manufacturers have been doing this for a long time. The typical
wiring in jets is sized at about a 95% load capacity. The larger power
feeders like from the main gens on the engines are separated by "air
spacers" to allow cooling air to circulate around the 2/0 cables. Jet
aircraft power is an industry standard 115v 3phase 400hz, and that can
really nail you!!! The dc stuff is a modest 28v and of course the 5 volt
requirements are there too.. But when I worked on big ships,  the 440v
60cycle stuff  is big time lethal.

 Here's a trivial pursuit tidbit for ya. The supersonic Concorde could save
6,000 pounds if modern electronics were installed. And it uses 93 TONs of
fuel from Heathrow to JFK.
