“The group filed a complaint with federal regulators, alleging that SmartMeter wireless transmissions could have created an electrical current in the pipe and ignited the natural gas.” You should be embarrassed for lending credibility to this ridiculous claim. Were you wearing your tin hat when your wrote it!!
Regarding "at some point in the future pg&e + others plan to communicate directly with your appliances. . . .". Communication to appliances and in home displays will generally facilitated through Zigbee or Home Plug technologies. See http://www.zigbee.org/ and http://www.homeplug.org/home/. Zigbee is a low power wireless technology and homeplug uses wiring in the home. Participation in in home display and demand response type programs where applicances, pool pumps, air conditioning, etc. are controlled will be voluntary. No utility wants to force people to participate in these programs. As for using power lines to carry cellular and smart meter data, etc., this kind of technology - "power line carrier" - is very expensive and hard to implement in the U.S. because of the design of U.S. electric distribution systems so I don't see this kind of technology making in roads in the smart meter marker unless some big hurdles are overcome.
In response to the "Debate is heated as to whether or not non-ionizing radiation is bad for your health," the articles you cite are in reference to cell phones and are not relavent to the discussion. You hold a cell phone to your head. The smart meter is on the side of your house. There is no comparison.
There is no need to turn off the power when replacing the meter. They just pull out the old, and plug in the new. So locking the power switch will have no effect.
All electricity used by the meters is paid for by the utility. It is not part of the customer bill.
The scientific validity of the "BioInitiative Report" has been called into question by several well respected independent and governmental organizations in the field of RF. Using it to support a connection between smart meters and health problems shows a lack of good reporting, an ideological bias on your part, or both.
Re: “Friday Must Read: Was It Pipe Corrosion, SmartMeters, or too Much Pressure in PG&E’s Pipeline; Reports of Gas Odors Appears to be a Rumor”
The cell phone-gas station fire connection is an urban myth.
The Discovery Channel Mythbusters put that one to rest. See http://mythbustersresults.com/episode2
"Using one’s cell phone while pumping gas/petrol can cause an explosion.
busted . . . A properly-working cell phone poses almost no danger of igniting gasoline, even when surrounded by gasoline vapor with the optimum fuel-air mix for ignition. The actual risk comes from an electrostatic discharge between a charged driver and the car, often a result of continually getting into and out of the vehicle."
