Quite possible in theory, and perhaps possibly practical,
in those long past days when grids hardly existed.
(each power station kept its own frequency and time, then)

These days it is more practical to derive power from the river current,
and to feed it into the grid, (if economical) [1]
and to drive a heat pump between Thames water and heating equipment,
with power taken from the grid.

Jan

[1] FYA, in the news recently, there is a highly original pilot project
to derive power from tidal currents using underwater 'kites'.
The kites are programmed to execute figure-8 motions,
and power is generated by reeling them in and out.
