Smart meters isn't a smart grid system.

It is a key element of the smart grid vision.

"Smart meter initiatives around the country in recent years have proven the
concept. They are cost-effective and maximize energy efficiency, leading
many governments to mandate advanced metering. Today a small fraction of
U.S. meters are smart, but the segment is expected to grow between 15
percent and 20 percent annually."

We have smart meters here. Most people do not like them as their power
bills went up 20-30%. I think the reason the utilities love them is it
calculates power usage better. With all the cell phone and computer low

Or it was simply programmed to overbill.. It's not a matter of calibration, when the
manufacturers intentionally allow features to be activated that will overbill the
customers.

voltage transformers in a house the power factor is wrong for great billing.
The power passes without being registered as a big percentage is mostly
inductive and the power factor designed in to a standard meter will not

The DC rectifiers on modern power supplies make them act more like capacitive loads..

record a lot of the energy used.

I doubt your claims..

"One coil is connected in such a way that it produces a magnetic flux in proportion to the
voltage and the other produces a magnetic flux in proportion to the current. The field of
the voltage coil is delayed by 90 degrees using a lag coil. [1]This produces eddy currents
in the disc and the effect is such that a force is exerted on the disc in proportion to
the product of the instantaneous current and voltage. A permanent magnet exerts an
opposing force proportional to the speed of rotation of the disc - this acts as a brake
which causes the disc to stop spinning when power stops being drawn rather than allowing
it to spin faster and faster. This causes the disc to rotate at a speed proportional to
the power being used."

I would bet those old analogue meters over the long haul are far more robust and accurate
than these newer meters.. (Newer electronic meters have a projected lifespan of less than
10 years. Guess who's going to get the short end of the stick when they fail??)
