Sounds a bit like a Stirling Engine, but driven by humidity differences rather than temperature differences. I'm not sure why you need an entire lake to generate the humidity though (perhaps more conventional/mechanical methods would do the same much more compactly) nor whether the air above a typical UK lake would have sufficiently lower humidity (thinking of mist/fog/cloud that often shrouds the Lake District) to drive the process.

If you're going to use lakes (or better still reservoirs) for power, you'd probably be better with a pump-storage scheme.
