Larry Lippman recently proposed the use of batteries for the power supply for
audio ethusiasts.  Before this is tossed off as another absurd wreck.audio
idea, consider the fact that many pieces of compact test equipment use 
rechargeable batteries rather than large filter capacitors in their power
supplies.  The portability feacture is "icing on the cake."  NiCads have such
low internal impedances that they can effectively appear as several Farad
capacitors in power supply applications.

Now for the inane comments!  Think of the prestige of having the only 250 watt
per channel boombox in the neighborhood capable of pumping out the noise for
hours and hours after a power failure.  :-)
