Thanks for posting that, Dave, you beat me to it. 

Those guys on 40 meters are right. Other things being equal, for a given power
output, running anything off 240 volts is more efficient than running it off
120, due to I-squared-R losses in the AC line. Whether or not that's what they
had in mind is not known, but their conclusion was and is correct.
