[R-390] electric cars

[rbethman]

My original higher voltage issue has NEVER been intended to squawk about 
long transmission lines.  It is the "local" transmission lines in 
neighborhood distribution systems.  That is the crux of the matter.  
This "segment" isn't being kept up to date with larger conductors, only 
"jacking" the voltage higher.  This is why you will see the 127VAC at 
YOUR receptacles.

This "power plants right at coal fields - and  using state-of-the-art 
gasification processes that result in (comparatively) low emissions" is 
not exactly new.  The Canadians have been doing this for awhile!  The 
corporations here keep getting their attempts "choked" by "those that 
make the laws".

This gets into politics - I WON'T GO THERE!
