Great minds run in the same gutter!  Not necessarily 'borrowing' each
others' ideas but more coming up with essentially the same idea at the
same time.

Apparantly they've been working on it for a while: "(though Ubuntu is
working on migrating to a different system called Wayland)" from the
March 3, 2011 post.

Looks interesting -- I'll play with it later.

Wonder if the instructor has sent a dancer to the rest room to wash their
hands for posing improperly?  Each/most positionings are supposed to 
mean something.

I haven't stumbled across any collection site either.

What was 'funny' is sometime it did manage to do the installation -- 
usually the 'Try Me' option -- and actually run - for a short while.  
Other times very quickly halted.  Guess all where the data was placed at
the time.

Nah: they access through the remote-read option of the electric, gas
and water meters!

Our generator is outside towards the back corner of the house because of
window placement ==> if the window is open don't want the exhaust drawn 
into the house.  

Your 'gas pipe to nowhere' might or might not be able to be used.  At 
one time this house had a natural gas air conditioner from a service 
station.  The guy who owned the house owned several gas stations and 
when they added the second span to the original I-74 Bridge (early 70's,
maybe late 60's - I've forgotten) one of his station was in the path of
the new bridge so eventually was torn down; he had the air conditioner 
moved to the house -- yes, there's a big cement slab off the house, now 
under the deck.  

So when getting the generator set up the salesman is shown the old gas 
feed -- it terminates about eight/ten feet from where the generator will
be.  ...Installer comes to do a site check - gas pipe isn't a large
enough diameter to feed a sufficient amount of natural gas when the 
generator starts up: will probably stall.  So had to have a new NG pipe
installed.  (We fought and had the seller pay most of the new pipe price
as their contract said it was satisfactory.)

Probably a smart non-move!

Right.  Hundreds of potential failure points; still have the old back-up
items: hurricane lanterns, flashlights....

That would probably work.  I'd add in backup power for the refrigerator 
- have a freezer?  Could possibly run one at a time to save on the 
overall load.  Also figure for air conditioning and heat.



 KM> And there's also the barn roof that faces the same way.

Darn! Forgot about the shed's roof!  8x10' storage building for the lawn
mower, etc., so whatever surface area that gives the roof.  Trouble is 
the neighbour's trees block the sunlight.

<chuckle>  (And no, the 3KW larger unit wasn't the cause of the NG pipe 
issue -- found out later the installer's paperwork still said 13 KW.)
