All you libs whine about oil.
Why don't you cruise out of Canada?

Again, show me where I have complained about oil.

The reason that I so not cruise out of Canada is because
there are few if any departures during the winter
for where I want to go.

(Not that it is any of your business)

I'm trying to get you to stay in Canada.
Yes you have whined about oil and now you play that old old game of telling me to show you.
Got some news for you, I don't keep a log of your anti American posts. Anti oil either.

I guess we need to post this again since it is obvious that Brewster's predictions about drought in the US is coming true:

Oh wait, he said something like "You haven't seen anything yet, the drought in the US is going to get worse and cover more of the US". Too bad or good according to your view point that his prediction did not come true.

LOL Brew's hurricane predictions are not coming true either. We haven't had a major hurricane in many moons.
Yes Brew you said this country.

I gather Neut thinks he's found a winning argument - ships use oil.

Brilliant discovery!

As usual for the US Right, he wants to claim that unless you stop using all Fossil Fuels instantly, there's no point in any of it, and we should do nothing - typical Denier "thinking".

Here's the real story:
Quote:
 
Nearly all modern cruise ships and ocean liners are powered by electricity. Electricity powers the motors that turn the propellers. It also powers the air conditioning system, the lights and other appliances used aboard the ship.

Most ships produce their electricity using diesel engines. Others use gas turbine engines to generate electricity. Still others use a combination of the two.

Diesel engines use heavy fuel oil (“HFO”) while gas turbine engines use marine gas oil (“MGO”), which is similar to the fuel used in jet airplanes.

Queen Mary 2, currently the fastest passenger ship in service, consumes 261 tons of HFO and 237 tons of MGO a day when traveling at full speed.

In order to reduce fuel consumption, the cruise lines are employing new technologies. For example, silicon coatings can be applied to the ship's hull to reduce friction as the ship goes through the water. On Celebrity Eclipse, the friction reduction is reportedly some five percent.

Ships are also experimenting with LED lighting, which uses less energy and produces less heat (and thus reduce the demand for air conditioning and for electricity).

The Celebrity Solstice class ships have a field of solar panels over the enclosed Aquaspa pool area. Not only does this provide shade for the pool area but the electricity produced by the solar panels is used to reduce the demand for electricity from the ship's engines.

Along the same lines, Queen Mary 2 has exhaust gas economizers, which use waste heat from the ship's engines to produce steam. The steam is used in heating QM2's hotel accommodations, in the ship's laundry, in the ship's galleys and to heat fuel. This in turn reduces the amount of energy that has to be produced by the ship's engines.

The key sentence in the article is that modern Cruise Ships run on electricity. While that electricity comes from Fossil Fuels right now, it's less than in the old days, and the more green energy we can generate and store in on-board batteries, the less Fossil Fuels the ship will burn. And that's without having to build all-new Ships.

I expect that within a decade, we will fly to the Cruise Ports in bio fuelled Airplanes, and cruise in largely battery powered Ships, with bio fuelled diesel engines used on long cruise legs..

And that is called Progress.

Yes the ship runs off oil. Thank you.
When Sea goes on a cruise he is contributing to oil.

So Neut, according to you,
if I do not go on a cruise no oil is used.

Amazing!
How much oil do you figure I have saved
by staying home this week?

Anyway, I figure that by using oil instead of electric,
I have saved the lives of one eagle, two starlings
and a crow!

No Sea. I said you are contributing to oil.
Can you ever comprehend anything?

How can I contribute to the use of oil on a cruise ship if I am not on it?

How much oil was used to bring across your made in the
Pacific rim electronics?
