Excellent advice.


P.S.  love your PV comment in your sign-off.  Do PV actually pay off in 
the long term, given initial cost, degradation, service and the like?  
Doubt it.  At least my calculations have indicated it to be 
cost-prohibitive in the long term model.  Now if I lived in a windy 
area, at least I could CNC some replacement parts to a wind turbine as 
part of a long term maintenance and repair effort using basic human 
ability.  I can't exactly develop and maintain a silicon fab lab (or 
readily find people to support it) to easily support poly-amorphous 
silicon production efforts and switch mode supplies for solar cells 
until we pull our heads out of our butts and actually learn to share 
this sort of manufacturing information.  This is why internal combustion 
engines won't go away any time soon.  Like Linux, it's established 
technology , readily shared and relatively easy to duplicate from a 
manufacturing/production standpoint.
