Climate change legit after all! Who woulda thunk it?

[JTScribe]

Ok, this thread has gone exactly how I thought it would. I'm only going to be replying to the comments that I see are the most "out there." Before I do though, here are my thoughts.

1) Climate change is very, very real. HOWEVER, climate change is NOT global warming. Climate change is actually a naturally occurring process, that takes place on earth over certain periods of time. Climate change can be dangerous, but only in the sense of when it's mentioned with global warming. There is nothing that can be done about natural climate change. Just like the seasons change, so does the climate. It's not scary, it's not doom and gloom, but it it's real, happens, and has happened.

2) I tend to lean more conservative when it comes to global warming. Personally, I think the data supports it, and that global warming is a real thing, but I'm still not sure the extent man is helping it along. The give away for me are the islands disappearing in the pacific ocean. These are small islands that have had many generations of people on them that are suddenly disappearing due to rising ocean levels. What would the people on these islands have to gain by saying such a thing? The reality is not much. If multiple generations of these native islanders are saying something isn't right, I tend to agree with them. Although, my thing with global warming is investing in clean energy. It doesn't have to be political. If you had sources of clean energy that could power your home, why not do it? Solar and wind power are insanely great assets, that in my mind we're ridiculous for not trying to harness more.

Which islands in particular are you referring to?

Is it these islands:

About Those Non-Disappearing Pacific Islands - WSJ

Or the islands where Leo DiCaprio is developing a beach-front resort.

I think the main thrust that many people have an issue with is the implied anthropogenic aspect of climate change. I'll believe it's a man caused crisis when the guys making money off of it or trying to control my life invest in mountaintop survival shelters and sell their beachfront property.

On a decent size wind unit, if you amortize the start up cost over 25-30 years (which is insanity) you get cheaper electricity than what you can buy off the grid. That is if you have no maintenance. But the units don't last that long. I looked into buying one. My in laws did as well from a different company. Same story.

The big ones they are putting up around here burn out in less than 10 years. They don't produce enough electricity to pay for themselves on the face, but it's even worse when you look at the cost of shutting down and firing back up a coal plant so you can put wind energy on the grid.

Solar on the micro scale is pretty much the same story. It's ok for small supplemental units, but achieving enough power for a household requires an investment in equipment and maintenance that isn't touched by the savings you get.

I used to like the idea, and wanted to use it personally. But it is barely economically viable in some limited instances with government incentives. But guess who is paying for those.

Not to mention the fact that if the wind blows too hard they shut them down because the turbines can't handle it.

I want the answer too.

You know the expression, "Never trust a skinny cook"? Well one of the cooks was skinny. But his wife was, shall we say, NOT skinny.
When she visited him one time, she sealed the hatch with her belly, as she attempted to climb into the sub.
Ventilation was still drawing air into the sub through the forward hatch. But no air escaping through the rear hatch, until she finally busted lose.
EVERYONE's ears popped.

Okay, my idle daydreaming was amusing to me, but knowing that something like that happened in real life is really funny! I hope she was not injured!




1. Agreed.
2. Agreed.




Not useless for people who pay taxes and are also paying attention.

That's the funniest thing I've heard all day....thank you for that

FYI: Hatches thru the pressure hull are 29 inches in diameter.

Except torpedo doors, which are 21

Did you name it "Hyman", after the Admiral?

We ate the banana. We did not name it.

 

[oldpink]

Well the ones over in our neck of the woods are newer and better. And they already know they aren't viable without the subsidies.

You must be talking about the ones on IN-1 between me and you.
I've suspected as much, having seen the blades on them sitting still or barely moving more often than not, and I drive by them daily.

Yessir, all between SR1 and Winchester and from SR32 to SR36.

And yeah, they usually don't run, and if they do, it's usually only half of them or so.

Submarines are obviously not built for me. Or maybe I should say, I am not built for submarines. I could fit through the pressure hull. Probably would need a shoe horn and some Vaseline to get through narrower places.

Hatch?
You surely meant "scuttle," or do you bubbleheads use a different term for that?
Only half kidding here.

For those of you unfamiliar with the term, a hatch is a horizontal watertight door, while a scuttle is a small, round (or rarely oblong) watertight door just big enough for a person to go through, usually in the center of a hatch, although there are rare scuttles (porthole, although usually too small for a person to pass through) that are on vertical surfaces or that are separate from a watertight door of any sort.

Here's a hatch only with no scuttle:

Here's a hatch with an oblong scuttle:

btw...there are lots of reasons for physical fitness and body size standards in the Navy, but scuttles are a huge reason for standards, as it were.

Bad things happen when the tips of the blades go supersonic (which can happen).

I think wind turbines and solar are awesome for some applications . . . if the person(s) using them intentionally pay(s) the full cost.

Those applications would be for places where you don't have viable alternatives and they're used to charge battery banks. They'd make a great prep to provide some power if your supply from the grid stops (or doesn't exist) to supplement what you get from generators. In those situations, the costs are less compelling compared to the need for the electricity.

Until there is a way to economically store the energy they convert on a huge scale, they're a non-starter for immediate use since they can't reliably supply what is needed when it is needed. Add the facts that a coal plant is almost always burning at or near full capacity while they are turning to accept the load for when they fail to supply enough current, and the hole is deeper. Add the maintenance costs, and it's deeper still. Considering the useful lifetime and the costs of decommission, well . . .

Without ridiculously huge tax subsidies, the big windfarms feeding the grid wouldn't exist. No one could make a profit or even break even, so whatever profit they are showing on their books is actually coming from those of us paying taxes.

Nuclear is the way to go. If the French can manage it, so can we.

Give all your money to "climate change programs". Leave mine the hell alone, I don't have enough let lone to pay for this trash. There a billion Chinese eating farting and consuming and contributing far more than us. Let them pay for it, we are their rounding error. There are also a billion Indians contribute greatly also. Let them be taxed also.

Nuclear FTW. The waste is small, manageable, and not without use. It is a hassle, but it can be dealt with.

People get scared, but the plants we had here are much better built than the ruskie's. They can be put in areas that are not at high risk for geological problems. And hopefully after Chernobyl, everyone knows not to run unauthorized experiments.

I always watch a video to the very end.

Looks like I will be busy.

I would hate to think I missed something.

Somebody say narwhals?

Thanks for that!

Climate scientist pshaw!

Those are from ships. We have no space big enough to put something like that onboard.
Trust me, I know.

I was on the USS LY Spear for some reason, maybe heading to the Squadron Command Office. The Spear is a Submarine Tender (Auxiliary).
Anyway, as I'm walking down a passage, an alarm goes off.
Well, on the John Marshall, I know exactly what to do, no matter where I am.
LY Spear, not so much.
A chief (chief petty officer) goes past, points to one of those "hatch with scuttle" that you showed, looked at me, and yelled, "Aren't you going to secure that?".
So I said, "Aye, Aye Chief!".
I had no idea what to do. That thing weighs mucho pounds and would chop someone in half.
So a couple sailors showed up from the Spear, and they were lower rank. So I asked the senior one if he knew how to secure it. He did.
So I told him to secure it, told him he was in charge of the work party, and I high tailed it to Squadron Command. Whew!


The hatch through the pressure hull looks like this from the top

And bottom view looking up

A non-pressure hatch through a deck looks like

And a watertight hatch (horizontal)

On the last picture, the bottom of the hatch is a little lower than the knees, and the sill is called a "knee knocker" from busting your knees when running to battle stations.
The top of the hatch is somewhere around your chest.
So, you have to step up, and bend to go through.
After I hurt my back, these things KILLED me.

PS, those pics were stock pics off the internet. I'd have to scan my pics in, and I'm too lazy.


I was on the SSN 611 (converted from SSBN 611).
This is how old it was, this pic is from SSBN 610 USS Thomas A. Edison

And this is from the SSBN 609

Notice the lack of "room".
It wasn't like the subs I see in the movies. That's for sure.

 

[bobzilla]

I also remember the global "cooling" scare.
Funny how everyone else has forgotten it.

Its worse than that. They now deny it.

 

[actaeon277]

Just like 1984. Doublethink.
