So,Comrade Obama has effectively BLOCKED new nuclear plants. Solar and wind will NOT make up the difference,nor will biofuels. End result is much higher electric rates,brownouts and blackouts,and/or a lowering of lifestyles.Industry will suffer,jobs will suffer. It also fits right in with his desire for high gasoline prices. (the lowering of your lifestyle) Our economy is closely tied to energy prices. That's Comrade Obama's "social justice". He's out to drag us all down to the "poor's" level. -- Jim Yanik jyanik at localnet dot com

Not too much meat in there, except two rather scary remarks, quote: "solid-state meter platform" and "Digital Multiplication Measurement Technique". That can spell trouble if not designed right. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.

I got the new meter about a month ago, so don't have any feel yet for how it compares to the old one. Other neighborhoods got them much earlier. I haven't heard anything from people I know, just the media stories. I can show you what the PG&E Smart Meter looks like, though. Here's a link to a zip containing 4 pics of the meter face... http://www.xertech.net/pub/SmartMeter.zip The LCD display cycles through several formats every few seconds. The two 'meter' pics show two of those displays. I was trying to get better pictures of the various display formats, but it started raining, so I ran for cover. The two label pics may have information to lead to more information (FCC ID, for instance) but I haven't tried searching yet. I assume this is the same one you will get. The cylindrical case is not transparent on the sides, but I would doubt there is anything mechanical in there (like a spining disk). I'm interested too. Post if you find more information. |
