How are you all? Hot under the collar?

You've not been a member long, have you? This is about as on topic as the forum gets. Post something about compressors and it will descend into a crackpot apocalyptic Christian theology rant.

Via pony bottles.

It has been warm to be fair.

Via pony bottles.

I went diving today, with a relative novice, and considered adding a pony bottle to my kit
I couldn't decide whether to side-mount it or mount on my cylinder it so I left it behind

I suppose you could do both and cover all the base's

This is me talking from complete ignorance having never used a pony cylinder

Time to read up on theology before posting something on compressors

No need, it has never stopped any of us commenting.

I call bull shit. I get around 60mpg from my estate car. My parent’s car was a similar size and used to get 30mpg. To get the 82% reduction it would have to have been less than 10mpg.

60mpg?? what car is it? I get 45 from my Rav and I thought that was good

But MPG wasn't the point i was raising, it was the reduction in C02 emissions.

Fuel economy with common rail injection went DOWN but so did the C02 emissions.

My Austin Rover Mystro 2000 diesel van did 50mpg fully loaded and pulled like a train. It would do 60mpg empty and on a cruse When they stopped making them (1991 i think) the AA bought Rovers entire remaining stock because they were so good of fuel it was saving them a fortune

But they stopped making them because of the C02 emissions from the direct injection diesel Perkins engine

Again, I call bull shit. You are comparing two different things and ignoring a very pertinent fact. The different things you are comparing are the emissions from the petrol engine and the emissions of manufacturing a whole car. The pertinent fact you are ignoring, and virtually all climate sceptics do this because it knocks such a large hole in their argument, is that the batteries can be recycled endlessly - petrol is a one use item.

No i am not I am saying that. The Mustang was already in existence so it would have been greener to drive the mustang than build the Rivan

But let me do the math for you again

Rivan = at least 50tones of C02 to build

Average petrol car 6 tones

SO a difference of 44 tones.

A modern petrol car emits (according to 2022 figures) an avg 116g per Km

So to produce 44 tones would take 379KM of driving

Sadly James Lovelock died today, the thinking man's environmentalist who wasn't too afraid to admit he'd made a mistake, he was the grandfather of global warming and the war on C02 basically creating the term



Some famous comments which endeared him to me:



The problem is we don't know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books – mine included – because it looked clear-cut, but it hasn't happened.

The climate is doing its usual tricks. There’s nothing much really happening yet. We were supposed to be halfway toward a frying world now.

The world has not warmed up very much since the millennium. Twelve years is a reasonable time ... it (the temperature) has stayed almost constant, whereas it should have been rising – carbon dioxide is rising, no question about that.



I am a Green, and I entreat my friends in the movement to drop their wrongheaded objection to nuclear energy"



In 2019 Lovelock said he thought difficulties in getting nuclear power going again were due to propaganda, that "the coal and oil business fight like mad to tell bad stories about nuclear", and that "the greens played along with it. There’s bound to have been some corruption there – I’m sure that various green movements were paid some sums on the side to help with propaganda"



He opposed the concept of "sustainable development", where modern economies might be powered by wind turbines, calling it meaningless drivel. He kept a poster of a wind turbine to remind himself how much he detested them.



It just so happens that the green religion is now taking over from the Christian religion.

I don't think people have noticed that, but it's got all the sort of terms that religions use ... The greens use guilt. That just shows how religious greens are



As I said my kind of environmentalist



A pragmatic one





Actually, most of the raw materials come from South America.



Sounds reasonable to me.



It will be better to reduce individual car ownership in metropolitan areas (car clubs etc taking over) and improve public transport both in terms of numbers of services and fares.

For a man who's spent (what was it, six hours a day?) doing his "research" I think you're remarkably ill-informed.

Having done zero hours' research into this I'm pretty sure that that diesel went out of production due to particulate emissions, not CO2. But, having not done any "research" I can't be sure.

As for the rest of your post, oh, I really can't be arsed, so I'm out of here. It's like playing the proverbial game of chess against a pigeon.

I see an analogy between you and iain/hsm. You both post(ed) interesting stuff about your specialist areas (diving / compressors) but utter drivel about everything else. It's a great shame, IMO.

Classic run out of arguments / feer of debate response. Particulates and C02? Possibly Particulates was a bigger issue but that wasn't the point. It was the particulate filter and catalytic converter era back when we were told go green go diesel. We were also told oil would run out by 2020 and the Maldives would be underwater but this never happened.

aren't you concerned the pigeon is winning
