This is cutting edge stuff, most anecdotal rebuttals here have been
based on old ideas and technology. Here's a bit more about it:

Several of us have done analyses based on the laws of physics, which
have yet to be repealed by new technology. Water mills are well
understood, have been around for a long time, and do not require the
application of quantum mechanics. A 20 inch prop being dragged
through water at 6 knots can generate somewhere between 1 and 4 KW of
electricity depending on how optimistic your assumptions are. Even
the high end number is not enough to recharge a *large* battery bank
in a reasonable length of time.
