What would be a good alternative for cruise ship fuel?
What I mean to say is that you see how these ships probably run on gasoline or coal, whatever it is it is producing alot of CO2….so what would be a good alternative????

The really big ships run on diesel engines which burn a very heavy oil that is relatively inexpensive and contains the most energy for the dollar spent.
The military runs its major vessels on either nuclear or turbine engines. Neither of which is appropriate for commercial vessel use.
Given the weight of these large vessels, it is unlikely to find an more economical fuel than the sludge they burn now. If you consider the number of cars compared to the number of cruise vessels, it would be far wiser to concentrate efforts and energy on alternative fuel automobiles.
Biodiesel
Nuclear power
Combination of petro, solar right now, but eventually more natural fuel and, or self regenerative sources.
Use big kites for sails.
Ships now use #6 fuel oil, also known as bunker C, in steam plants, or diesel fuel in diesel systems. Because of the huge amount of energy needed to move a ship, renewable energy sources are not a viable replacement. However, wind assist is being used at present, in several forms. Conventional sails, non-conventional sails that look like a smokestack, and kites are demonstrated below:

They run on #6 diesel usually. Toshiba makes a nice, small (5mw) pebble bed nuclear reactor. A couple of those would run a cruise ship for years without refueling.
don’t go on a cruise. Sails.
