That's the one. The testing has been positive apparently and the company that is building it reckon > 10% fuel savings. Of course though that only happens once!
They are now tracking the bulk carriers spewing black diesel smoke across the oceans by satellite and I think I read that they will be nabbed for pollution.

Actually whilst working recently in Dar es Salaam port I can verify the dirty, filthy exhaust spewing out of the container and LPG ships once in harbour. If the wind blew the wrong way I'd be breathing the bloody stuff in. Horrible

I believe this is called "black diesel". I've been on a few veggie oil sites and this is quite the in vogue cocktail for diesels. Filtered first though.

Talking of green bits for ships, have you seen the spinning mast that's being used now? It's a tube that spins and uses the Magnus effect called a Flettner Rotor, I think similar to a wing and the low pressure at the front "sucks" the mast / ship forwards. Very interesting but old tech

Alas, all I know and understand of ship propulsion is an engine room, and these days all I want to know about it is that someone else is keeping watch on the engine room of whatever cruise liner I'm aboard at the time.
The ship fuel issue with regard to atmospheric pollution is big, as has been said there is lots of pressure being placed on land based motor vehicles, and there are so many of them, but none the less these large ships with enormous engines plying our oceans are "cheating" with fuel and causing areas of enormous polution. We were sailing the Gulf of Thailand 6 weeks ago and there was a permanent "smog" on the ocean, the shipping is so concentrated and every ship is burning "dodgy fuel", and that pollution would not be tolerated in Sydney harbour or off the Australian coast but it's ok up in Asia.

I agree there and my sister lives in Sydney these days. We diesel drivers in the Western/first world nations are getting hammered and yet it's ok for these ships to do it. I've just started to use SVO in mine and if I do a 30% mix I'm saving £12 / $20 ish AUD per tank of fuel, and the emissions are cleaner. I'd like to make my own WVO but that's a future project.

I for one am happy that they are tracking these ships by satellite. They should instigate a no berthing policy if the ship is caught polluting at sea.

My wife works for Facet (beloved of veggie oil users) and she looks after bilge oily water separation plants BECAUSE of polluting the sea water. If we can't pollute down then they shouldn't be able to pollute up either - or vastly minimise at the very least.

I'm no Greeny but I don't want the planet wrecked but it's shocking that they get away with it.

Finally got the pipe out that goes across the rear, what a convoluted thing it is, no way I could see of getting it out in one piece without the body off, so I cut it. Fed the new pipe across re-using the clips and re-routed it either side to reduce the number of bends needed. All existing clips used bar 2 and I have covered the pipe in nylon high pressure airline to protect all exposed areas. Photo's to follow.

The tax has to be applied in all countries or they'll just fill up where no tax. I suspect that's a stumbling block to taxing fuel for ships and planes.

the thing with taxing aircraft and ships is that essentially the fuel is uplifted in country A and used overflying country B and C etc. with ship once in international water the taxation can only last until exiting the uplifted country's water. In essence you are exporting the fuel to be used outside of the uplifted country. with the thousands of flights each day in and out of each nations airspace recovering the taxable element would cost significantly more than any revenue generated
