It more than likely costs them time in the laundry and soap. They probably have the signs to create a self righteous image that they care about the environment despite the fact it will have little impact.

I never use the same towel on a cruise ship as it is dirty and un hygeinic. There is not enough room in bathrooms to adequately dry the towel opposed to your bathroom at home or the cloths line.

We've just returned from a trip and found that towels used after a shower dried beautifully when thrown over the pull-out clothesline. Cruise ship bathrooms usually have good air circulation and more warmth than domestic bathrooms. We made a point of reusing towels before leaving them on the floor.

Please tell me your mechanical qualifications as a shipwright or your experiences working in ships engine rooms?

Desalinating water on land is expensive, and to the simple minded folk with no brains or concept to do rational reasoning and use your brain people think the ship version is expensive too.

A ship at cruising speed is using "X" amount of oil to propel it through the water and generate power. In that "X" amount of oil enough power and heat is produced to desalinate water as a side effect of the engines running.

The ship will have to use the same amount of oil to propel it at cruising speed regardless, so with the excess power and heat from the engines of course they can desalinate water and have an unlimited supply.

If desalination is expensive why do ships do it? Cant they just buy cheaper water on land.

I am amazed at the stupididy and lack of knowledge of people who shoot their mouth off without knowing facts.

Not all people can affored suites your majesty!

Some people are just happy to settle for an interior cabin on "A" deck, and enjoy the cruise just as much as people in the best suite. There are also standard balcony cabins and ocean view cabins I have used (exactly the same size as an interior) that still do not have the room to adequately dry towels.

The excess soapy water from the laundrys would go into storage tanks and offloaded in ports to be treated.

Seems as if you are referring to your onw posting.
Just because excess heat might be used does not mean that no resources at all are used to desalinate and condition the water. Also, a lot of ships do not use the excess heat but another process to produce portable water. (osmosis or reverse osmosis)

And where do you think this excess soapy water is going?

My professional qualifications is that I have actually worked on ships in the Royal Australian Navy! You cant beat first hand work knowledge on a subject opposed to an armchair critic who thinks they know all (who has probably sat at home all life and never worked thinking they know everything)

And you may be proud of having convinced us now that this does not necessarily mean a lot. Your 'first hand knowledge' seems to leave any out common sense or basic general education.

I wish ships had more self service laundries aboard instead of some of the foolish things(eg boxing ring) that have been put on them lately. I remember that the Tahitian Princess had one and it was ALWAYS busy.Besides the ships service laundries are expensive and I don't think that cost is a reflection of how much it costs them to run them.They know people will pay if they didn't bring enough clothes for the trip.

Agree about the need for on board self serve laundry facilities, particularly if travelling with children.

Cruise ships generate enough power to supply it to a small town far greater than the capacity of the cruise ships passengers and electronic systems.

It is not economical to have that power go to waste when you can use it productively to desalinate water.

I am not going to have some silly twit tell me that desalination costs money.

Simply my first post stated that desalinating water is not draining extra power or oil from a ships engines than they already produce. Therefore with no excess power or oil being burned it is not harming the environment.

I also stated that I dont recycle my Queen size towels as there is no adequate room to dry them in a STANDARD bathroom.

Then I have a silly twit respond with no technical knowledge stating that it costs money to desalinate water to wash all those towels.

Also, ships produce precisely the power which is consumed aboard (like power plants ashore) - there is no excess power one has to get rid off. Like with any thermodynamic cylce process there is some excess heat which CAN NOT be converted to work. This excess heat can of course to a certain extent be used e.g. to heat water.

He has read your comments - suffice it to say he was not impressed by your qualifications.

And here I quote Ernst -

There are no machines which give you something for free - even to access the excess heat of the engines some work is required. (Or how do you pump the water or evacuate the usually used vacuum evaporators?) Not to talk about the mysteriouse excess power availabe on ship.

It also does not require any expert knowledge to understand reprocessing water produces some waste - it has to go somewhere.

I did (I thought) post this earlier but Joe perhaps (as is his privilege) deleted it - and may well do so again - no problem because it is really OT

Quote: Talk about being OT

Frosty – I didn't ay that towels didn't dry overnight - I said that towels used after a shower dried on the pull out clothes line – they do –because they’re really only damp and would have at least 4 to 6 hours to dry off before reuse. We don’t take towels into/under the shower and are careful to have the shower curtain properly positioned so there’s no need to mop up the floor!

A question, after your pre-bed shower do you leave towels on the floor, perhaps to trip over on a call of nature during the night? Could happen you know......foot in the wrong spot and before you know it, ooops! you're on your backside

Now, a general observation - we're 2 in this household - usually 2 showers per person per day - that's minimum 28 towels per week - we pay for water, detergent and hydro power, some woman/man power is also required. Who does the laundry in your house? Bottom line - we re-use bath towels!

This discussion would probably fare better on that ‘other forum’ where such trivialities are discussed ad infinitum (End quote).
