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?

lithium battery (~10 year life).
funny but they are removing them around here as the remote reading trial
wasn't very successful.
