I've been interested in ocean wave power since 2006. I proposed doing
it on the BC coast where we have some of the best coastal wave
territory in the world for it.
Instead of an environmentally benign, incrementally constructed, 3
billion dollar wave power facility here, the BC government chose to
do an 8 billion dollar hydro dam and flood a huge valley on the Peace
river in the far north, where the power will have to be transmitted
over vast distances to where it's needed.
I couldn't get a few thousand dollars to do a proof of concept
prototype. A guy in Denmark got an award and government backing a
couple of years later for a similar design.
Usable wave power is estimated in the lower 10's of kilowatts per
linear meter of wave front (it's up to 2 MW/m in severe storms).
Use of wave power in boats for propulsion could be done by the
'direct' mechanical designs indicated, or by making electricity used
to charge batteries that run an electric motor - including while at
anchor. Doing it electrically allows storage. Then the power can be
used at any rate to attain a desired stable speed.
Wave power just might be a better way to generate on board
electricity than a wind plant or solar in some areas.
Cheers,
