I've been contacted by the gas people saying they need to change my
meter - strange as it's not that old. Phoned them to confirm the
date and asked the very pleasant guy just why they wanted to change
it so soon, and he said the new ones can be remotely read. By that
I take it to mean some form of radio link. So where do they get the
power for that from?


It's a passive chip in the meter. It doesn't need power. It's like
the chip in your credit card you use in the shops (or probably like
"your" credit card that your wife uses in the shops :-P)

The little man comes round with a reader / scanner thing, and holds
it up to your front door. It activates the chip in the meter and
sends him back the data. He doesn't even have to knock to see if
you're in.

I'd be interested to know how that works - the meter is some 5 mtr
from the front door and in the cellar.

Shock horror! Its supposed to be under the stairs - or not if you are
Drivel :-)
