Fuel Shortage

[Bob]

So as not to go 'Off Thread'. Do we remember 2000?

Fuel shortage - read 'Blockade'.

3 Days and the country was about to close down as there were no fuel deliveries which meant no deliveries and no one in work.

The reason people couldn't buy petrol was the (diesel) trucks couldn't deliver.

3 Days.

Hi
Still got my fuel ration book from '73 or whenever it was
Cheers

[Gasy]

Yes I remember I do a 1000 miles a week for work
And my works van did 57 miles with the fuel light on to get me home on the 3rd day
It got a big hug and a well done when I made it home that night

The case against diesel is just pure conjecture.

NOX MAY cause respiratory problems for some people over a long period of time.

That NOX MAY be emitted by diesel engines - but it may also have been emitted from many other sources as well, EVEN (whisper this quietly) SOME petrol engines, especially the very efficient ones, as it is often produced when fuel is burnt most efficiently.

No one can supply the name of one person who can be proved to have died directly as a result of diesel emission of NOX over any period of time whatsoever - it is all pure supposition.

I can supply the name of a person who died very quickly indeed from direct inhalation of petrol emissions and 2 other people who died as a direct result of the dangerous flammability of petrol.

Why is this supposedly advanced scientific world not capable of making fuel that is cleaner ? Can you not process diesel to be cleaner ? Surely there are chemists that could be employed to resolve this or at least improve emissions released.

I suppose they are employed sending a shuttle to Mars or some other pointless waste of time and money.

[Northern Bongolow]

it mostly about supply streams, and the use for each fraction that is split from the crude oil. once upon a time when we made things in this country we split our own crude oil from this we got hundreds of chemicals and of course diesel and petrol, now we make nothing we have no use for the chemicals so its cheaper to import finished fuel and leave all the chemicals somewhere else in the world.

It has been cleaned up considerably in recent years and "Gas to Liquid" fuels like Shell V-Power/Nitro are very clean indeed.

But it is the efficient combustion at very high temperatures of diesel that produces NOX, the only easy way to reduce it is to cool the combustion down and reduce the amount of oxygen available with recycled exhaust gas, which makes the engine less efficient and produce more of other pollutants instead. Heads you win, tails you lose.

On a mixture of veg oil and Shell V-Power my 170,000 mile engine produced no measurable smoke etc. on the MOT test, but I expect it still produced it's fair share of NOX and NOX is the current "nasty" for us all to be worried about - it used to be Co2 but as we've just been shown that isn't a problem any more, low islands will just grow bigger as sea levels rise.

[BongoBongo123]

You seem to know what you are talking about. I never see any smoke from my Bongo either. When I bought it I asked the guy to stick his foot down for us at stand still and nothing came out when he revved hard so I took that to be a good thing.

I just try and drive as smooth and economically as I can.

I did not understand what you meant about islands getting bigger as seas rise.

It was in response to something in the link posted on the other thread - apparently someone has surveyed all the low lying islands in the Pacific and showed that they grow as sea-level rises, so the islanders have nothing to worry about.

I did not understand what you meant about islands getting bigger as seas rise.

There has been some research recently about natural islands actually getting bigger as sea levels rise. It sounds backwards but it is to do with shifting sediment, and when the islands are left to their own devices they tend to cope well.

From what I could tell it wasn't all so peachy though as this natural method doesn't work where we've intervened and put walls and concrete in etc.

I cannot quite comprehend how that occurs unless it is happening already i.e tectonic plate shifts that raise islands. I think you or I would be worried if you lived on the coast. Not so easy to just up house and move to the peak. Kind of like your house now being submerged slowly in water.

It appears contrary to the programme I just saw about Jamaica where children were throwing rocks into mesh containers on the beach because storms that are frequent now erode the beach and their houses on stilts are going to fall into the sea.

I would like to see the peer reviewed reports of these surveyors. It almost sounds like oil company sponsored propaganda line, sorry to say. What about people, houses, community and lively hood. This is what is affecting people irrelevant of a sandy dump on the far side of the island that's so happens to be bigger. Just saying like.

Its a full peer reviewed article that appeared back in 2010 here is the link to the full paper, the problem with a lot of these papers is that the don't match the current Politically Correct headlines required to get wide circulation in the media;

Increase in area is one thing, but does the existing inhabited land area rise in line with sea level?

If so how?

PS it appears that the survey was only of reef atolls where the coral can "grow" the island.
Not of "normal" islands that are made of rock.

[g8dhe]

First which islands in the Pacific are made of rock then ?
They appear to have only measured area, not height, given that it was from aerial photographs and similar.
The islands effectively move as I understand it, with the new sediment being washed up whilst old sediment is more slowly swept away, the sediment being the remains of the coral, thus the area in general increases over time.

Completely irrelevant..

I was once talking to a teacher about worms bringing pebbles up onto my lawn ..

He said they don't it's caused by 'displacement'.. vibrations cause movement in the sub soil .. this works it's way under stones and lifts them ...

He said an experiment it to bury a stone in a glass tumbler filled with sand .. vibrate the sand filled tumbler and watch as the lower sand displaces the sand under the stone 'jacking' it up ..

Never tied it so dunno if it was fact ...
