Good choice. Aluminum is crap for electricity.

Not really. Aluminum wire is used in just about all power transmission
lines including that which connects to your house panel.

Aluminum wiring within the house was a problem back in the 60's and early
70's, but the aluminum wire wasn't the problem.
The problem was with the terminations and connections. Aluminum will
oxidize creating aluminum oxide which is an insulator
rather than a conductor. The type of aluminum alloy for wiring was changed
and terminations developed that prevent oxygen
from getting to the aluminum. Nothing wrong with it now if the correct
terminations are used. For power transfer ... like what
Harry is contemplating for his house genset, there's really no reason to
spend the extra $$ for copper power feeds from the
genset to the house panel. Aluminum is just fine, in fact is preferred over
copper for that use.

When we installed our pool and accessories a few years back, all the power
runs ... including a 100 amp, 240 volt service to
the pool filter and heater were all done in buried aluminum power. We also
put a 50 amp, 240v service outside for use with
an RV we had at the time. The contractor also pre-wired a feed for a house
genset that he was trying to sell us at the time.
We never put it in and quite frankly, I wouldn't bother. The amount of
time that we have lost power in the last 10 years just
doesn't justify a whole house generator IMO. If the power is out for more
than a few hours, I just fire up the little Honda
EU-2000, plug in the refrigerator and a couple of lights and we survive
fine. The longest recent period without power was
during Hurricane or Tropical Storm Irene and that was for about 36 hours.
To tell the truth, it was sorta enjoyable without
TV, radio, computer Internet access, etc. Nice change of pace.

Aluminum also is bad to work harden and has a high coefficient of
expansion. There is NO WAY to interface aluminum and copper without
dissimilar metals corrosion. Aluminum sucks as a reliable conductor.

Wrong. Look up at the power lines........
