This method seems workable. Their website has a video showing complete 360 rotations but I think if they use an alternator it wouldn't matter if it makes complete 360 degree rotations. Any motion on the weight/pendulum/flywheel would cause motion and generate electric current .
Waves don't come at the exact same frequency and the period of the wave chages, so the timing of the waves could actually counter the rotational forces.
Anyway here's the link

Here's another video i found on youtube

The power piston is a long way away from the displacer.

I made a very similar comment on the video and it was removed.  :-(

Maybe I missed it, but it seems they were very careful not to mention the amount of energy produced over the course of the year.
