Its not that long ago that I heard about the extensive hydro power

The London Hydraulic Power Company, AFAIR.
I think you'll find that the system had been defunct since
full telephone access had covered the City and they'd lain
empty ever since.
They were then bought by Mercury when they were first allowed
to compete with BT and saved them a fortune in the cost of
installing their cables.
