I thought the win was oscillation of electron rate vs direction, which presumably is a more efficient way to drive AC motors and other things. The light bulb insert was simply a diode (bridge?) so it did loose voltage in addition to rectifying. Presumably the power consumption of the device was nominal.

But do you think there is merit in the device? // George -- George Georgalis, systems architect, administrator Linux BSD IXOYE http://galis.org/george/ cell:646-331-2027 mailto:[EMAIL PROTECTED] -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
