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. Eisboch |

Without electricity, we have no water...we're on a deep well. No water to drink, no water to wash, no water to flush toilets. Without electricity, the food in the refigerators spoils. Without power during a long cold spell, the water lines near the exterior of the house can freeze. We have fairly frequent power outages out here in ruralville. -- I'll believe corporations are people when Texas executes one. |

If we didn't have town water I probably would have a generator installed ... or get one for the tractor power take-off. We had a similar situation to yours in Florida. No power = no water. You can survive for quite a while with no power as long as you have water. Our house here in MA has gas (propane) for the stoves and also for the fireplaces. We can generate some heat using the fireplaces (although very inefficient) and can cook etc. on the stoves. So, lack of power isn't a major problem although it gets old fast. Eisboch |

Eisboch ---------------------------------------- The oxidation was not the main problem. Was what showed up because of the connections getting loose and then the oxidation formed, causing fires. The aluminum has very little elastic range. Where it works like a spring, so the aluminum actually cold flows and gets smaller under the screw connection. Therefore getting loose. They use some special boxes that include a spring like connector to keep the connection tight. Big electrical lines are aluminum as the weight is significantly less and they can run fewer towers. The 500KV main power grid lines in California are very large aluminum wire. |

Overhead transmission lines carry very large currents, so high that the "sag" from the I2R heating causes problems. That is one reason why our overloaded grid is so inefficient. There are some estimates that far more than half of the power generated, never makes to the meter. It may have a lower current density than some local wires, but those lines carry huge amounts of current. The wires look to be 4-6" diameter. When a crop dusting plane hit one years ago, the plane pretty much vaporized according to a friend who worked for PG&E near the crash. |
