Not enough people are, because he keep's saying that there is no issues.

 

What the best way to get a note to John?  I know he has several facebooks pages.

One idea here is a feature on the Carnival Hub app where guests could report "customer service/ safety" type issues.  If it is super warm, or there is a spilled drink in a walkway or the like you can press a button.    I think the app knows where you are on the ship?  It might even be there already.

You can bring those kinds of issues to the attention of any crew and if they can't take care of it, they can notify someone who will.

So, where does Miami get the power to run the pumps that pump the geothermal water around the system (and that is not deep sea water, but water circulated to the deep ground, which is cooler), if there is no fuel burned?

 

Not sure where Miami gets its power from, but they are not burning oil to get it. I think even coals are better for the environment than how a ship makes electricity, but on land it could be nuclear power, or wind or sun.

Geothermal heating/cooling (which I think is not common in Europe), uses water that is pumped down a hole in the ground, where it is cooled off by the earth (to about 50*F at 20 feet down or more), and then pumped to the cooling/heating coil for the house to directly cool the air, without any refrigeration system (and its attendant compressor, etc). 

 

It's not that uncommon in Europe, but usually it's actually heat that is extracted from deep down. And there are all sorts of similar projects like storing heat in steel during summer. 

 

The Netherlands has a whole network to bring CO2 from factories to greenhouses, heat from factories to homes, etc.

How long would it take to pump this refrigerant on and off the ship. 

 

The point is that it is cheaper to produce coldness on land. How to transfer it to the ship is the next question. Pumping refrigerant may not be the best option, but when the ship is in port it may rely on land based produced coldness. For that you don't even need refrigerant, it would be connecting two water pipes from the ship to two pipes on land. Hot water to land, cold water back. And just pay for ever calorie that the port takes out.

 

The port would need to find a way to cool the water, but they have more options and could, for instance, use the cold water from the ocean. The ship already gets fuel, food and drinks from the port. And because it's cheaper and nicer for the environment, sometimes electricity and water are also taken in from port. If it's doable, why not let the port do the cooling as well.

Natural gas powers 75% of Florida power plants, with fuel oil as backup.  And, you'd be wrong about coal being cleaner than oil.  Coal is by far the dirtiest fuel there is.

So, that would take care of cooling while in port.  How do you store this for when the ship is at sea?

So, the port needs to finance the infrastructure to run piping out to where they can get to deep water?

Water is not cheaper to take from port than to produce onboard.  Shore power can be cleaner than ship's power, but again, only when in port, so how do you let the port do cooling while at sea?

You wouldn't. When the ship is at sea the electricity doesn't come from port either. But when in port, there are nicer options.

Yes. And get paid for it by the ships. Exactly like electricity and water. And like some ports require the use of their electricity, in the future they may require using their AC as well.

Still, municipal water is sometimes used on ships. It would depend on the itinerary but ships spend a lot of time in port. I understand you cannot provision a ship at sea with electricity or cooling or whatever, but when in port it does work for electricity and water. Cold water seems like a logical next step. At least it's less SOx that the public gets upset about.

I have met people on cruises that could singlehandedly crash the system constantly reporting "issues" .

 

About the Horizon temperature- I was on the first week in May.  Have sailed Horizon a handful of times.  Our stateroom temperature was fine and thermostat response worked.  I did notice that I did not need to bring a sweater to the dining room or to the casino (as I usually do).   I didn't notice any other indoor areas that were horribly cold or hot.  I know for sure I got a sunburn the day we were in Bonaire and normally that would make me feel really cold at dinner, or afterwards in the casino.  Although I didn't need a sweater for dinner in the MDR each evening, neither was I overly hot.  The casino I did find uncomfortable.  Usually it is cool to cold.  I was too warm.  I didn't think much about it since I assumed my person internal thermostat was broken by sunburn or alcohol consumption.  🤣

Yes. No telling how many complaints originate with Cheers. I have seen people sweating bullets but determined to get their 15 drinks in. I thought one was going to stroke out any minute.

He has one FB page.  There are lots of fake JH FB pages, though.
