captbillc is on a distinguished road
in 1952, when i sailed on the silvania on the great lakes (triple expansion steam engine) the boilers were hand fired. as oiler, one of my jobs was to start up the ash elevator and sluce the ashes over the side while the coal passer shoveled the ashes into the ash elevator buckets from the fire room floorplates.you would not be able to get rid of the ashes like that now. because of pollution laws, so where would you get rid of the ashes?

To those who don't think we should burn any fossil fuel, buy a bunch of 200ft oars, I'll buy the pair of drums.
That's really funny. But somehow the people who have this idea always manage to be the people who are being rowed by someone else or have the drums.

Thanks for sharing that knowledge. I knew that some electricity plants run on coal instead of fuel, but they don't have the storage space problem of a ship.
Only some burn coal? It's 57% in the US and 41% in the world for electricity generation. A lot burn natural gas. Only 6% comes from oil. coal electricity, coal power plants - World Coal Association

Yes coal does take more space for storage. But not that much more.

There are problems like the coal dust and coal fire hazard, but those can be overcome. The other problems have been overcome in power plants. It can be done on ships too. That power plant in the picture is 1000 MW or 1,340,000 horsepower! The Emma Mærsk is 80MW.

Dump them in the ocean or put them in one of the coal bunkers and then dump it out when in the middle of the ocean. The Luddington Ferry is still dumping the ash in the lake but they have to change that soon, and they don't want to.

Health risks of shipping pollution have been 'underestimated' | Environment | guardian.co.uk

Wow it looks like the pollution from burning bunker fuel is really bad. They say that they put out more harmful pollution than all of the world's cars combined.

Nobody here works for an oil company do they? Why is there so much opposition to using coal? There are coal power plants everywhere. Sure they put out pollution but nothing near as bad as bunker fuel. What's wrong with having a coal power plant at sea?

I think CO2 is good for the environment, even though the amount we make isn't really significant. Plants get bigger and use more CO2 to make more oxygen. Then everything thrives.

Perhaps digressing...
I remembered reading about this a few years back but haven't heard much since.
BBC NEWS | Europe | Gone with the wind on 'kite ship'
Kite-powered ship sets sail for greener future - Telegraph
and more recently...
Cargill ship will be largest ever to utilize kite power

Claims of up to 35% fuel reduction seems like a good thing to me if they can apply it practically.

No, US Merchant Marine Academy (Kings Point). I did once teach a course as an adjunct at Webb in the 80s. Sophomore Marine Engineering. And I am currently working with a pair of seniors there on their thesis project - use of alternative fuels in a diesel engine. Never met Jens Holm but know Al Rowen very well. Small world!

Burns coal.

I get mildly amused with the vocal "Save the Whales, Kumbaya" gang who are themselves profligate consumers of the Earth's resources.
