Fools.
I believe the EU already has efficiency rules for power supplies and EU supplies typically have much better Power Factor profiles than US supplies for that reason. According to Wikipedia, the EU regulation only applies to switching supplies. As I understand it, efficiency isn't just good "green" (lower energy demand) design, it's also better for the power utilities' gear. Given the same actual power demand, the utilities would rather have a larger more efficient device on the grid than a smaller, less effcient one. With switchers being lighter, cheaper, and more efficient, I don't expect any typical electronics vendors would bother with linear supplies, so legislators could achieve 99.99% of their objectives by leaving an exemption for power-hungry linear supplies. -- peterw http://www.tux.org/~peterw/ free plugins: http://www.tux.org/~peterw/#slim BlankSaver BottleRocket FuzzyTime SaverSwitcher SleepFade StatusFirst VolumeLock ------------------------------------------------------------------------ peterw's Profile: http://forums.slimdevices.com/member.php?userid=2107 View this thread: http://forums.slimdevices.com/showthread.php?t=35430 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
