A new design ship in the Philippines is partly powered by wave energy

Are there any technical details available for this system? The linked article doesn&#x27;t do a good job of explaining how it works or how much impact it will have.<p>Assuming the boat can harness 10% of the wave&#x27;s energy, wave power in the Philippines is more like 10kW per meter of wave length captured on average so that equates to ~1kW per metre of wave. Let&#x27;s assume this boat can capture roughly 10m of wave then that is an average power generation of ~10kW or ~ 10hp. A boat of this size will probably have 500+ hp engines so a boost of 10hp won&#x27;t have a huge amount of impact.

&gt; The emissions from travel it took to report this story were 0kg CO2. The digital emissions from this story are an estimated 1.2g to 3.6g CO2 per page view.<p>Maybe this is what finally could push companies towards making lighter and more efficient websites? At least an estimate of a webpages watt usage (server and client side).

It looks like there&#x27;s nothing in the way to put something like one of those kite-sails meant for cargo ships on a ship like this one to reduce the fuel needs and hence the carbon footprint even more.

When I see a wave foil I wonder how that doesn&#x27;t make more drag than power...is this similar or something different?

I&#x27;ve been long enamored with Philippine boat making. The first time I was asked if I wanted to ride in a canoe, I said no and had horrid flashbacks of tipping over in dirty ponds in the south USA. Theirs, even homemade ones, have stabilizers. Such a simple, but brilliant idea.

It’s honestly a shame that we didn’t keep pursuing sail technology. It’s great that we’re finally getting somewhere environmentally-friendly with ship tech nowadays as in the OP, but if we’d put the same amount of effort to innovate and advance sails like we did steam, I imagine we’d have pretty amazing (and completely green) methods of transport for all but the heaviest cargo loads (and even then, just split the load across multiple ships?).<p>Of course, nowadays the tech is probably so far behind that the cost of the necessary innovations to “catch up” sails to modern powering methods is completely prohibitive; I guess the environment will continue to take one for the team...

This is a great endeavour but where is the scale model that proved the concept?<p>I know scale models don&#x27;t meet up with realistic waves when on a pond but it would be nice to see this working. As it is the story is not there yet!

Aren&#x27;t all ships partly powered by wave energy if they&#x27;re facing the right way?

I&#x27;ve been in one of the traditional Philippines boats on a trip to an island in not so calm seas, we hired the boat and crew for the day.<p>It was an interesting but scary experience, probably won&#x27;t be doing it again. The island was decent.

Novice here - isn&#x27;t there some static hull shape that would react to waves and result in motion, much like those plastic widgets that spin only in one direction?

Renewable energy to power boats?! It’ll never catch on
