" I wonder if there is a significant difference in power consumption between
" a linear and switching cell phone charger.  

considering how little they draw to begin with, i'd guess not.  enough
for a night light?  maybe.

" I read an article once stating
" that a TV uses 85W (!) on standby.  They didn't specify how old of a TV or
" what technology (LCD, CRT, etc.) might pull current like that, but that
" seemed awfully high to me.

it might be either a big honking projection set or an old,
pre-energystar model.  long ago it was discovered that if you kept the
picture tube filament on half power all the time it
1. went to full power very quickly - 'instant on'
2. lasted longer, without the full power-on surge and thermal shock -
   the phenomonon that makes incandescent bulbs blow when you turn
   them on.

i don't know how much power a tube filament draws but i expect that
even on half power it's nothing near 85w.
