A bit of a tangent, but interested people might want to look at https://en.wikipedia.org/wiki/Fuel_economy_in_aircraft

 

The most efficient aircraft per passenger is a Bombardier CS300 over a range of 1900km... 1.85L/100km. That compares well to most ICE cars if they're carrying less than 3 or 4 people. Of course, 4 people in a car is about as cramped as as airline seats. A full 63-seat bus averages 0.41L/100km per seat.

For fun I checked what it is for Concorde; 16.7L/100km per seat... [same wiki article above]





Procrastination eventually pays off.

CO2 does not care about L/100km, it is released when it is released. So driving 10 km a day vs flying 10,000kms, that's 1000 days of driving. Or 3 years (assuming some days you stay at home).

I don't understand what point you're trying to make.

 

If I want to travel 1900km (e.g. Invercargill to Auckland, ignoring the fact that part of that is a ferry, so perhaps more realistically San Francisco to Houston) then, unless I have 3 or 4 people in my car, I will cause less carbon dioxide emissions if I fly in a full Bombardier CS300.

 

Whether I do the drive in one mammoth day or spread it over 3 years, it will use the same amount of fuel, and therefore emit the same amount of carbon dioxide.

LOL - to CSI comment.

So much for the BS claims by a certain politician also involved in the swamp kauri business - that the pipes "corroded" after the coating was damaged - some time ago.

Someone will know they were responsible for that damage and be perhaps waiting for a knock on their door.

This is also one of the fundamental issues when people talk about planes that can fly from NZ to the UK in the future. When you start approaching (or exceeding) a 20hr flight you're actually burning a huge amount of fuel just to carry the fuel required for such a distance. Does that actually stack up? Not necessarily. If you look at Qantas with their PER to LHR flights they have a very low density cabin to try and maximise passenger comfort for an 18hr flight.

 

The downside of this is more fuel + less passengers = more cost to the airline which ultimately means higher fares.

 

Given the choice of a 20ish hour flight from AKL to LHR direct when it becomes possible vs a 12hr and 10hr flight with a stopover I'd still far prefer the stopover.

My WLG -> BOS calculus is as follows:

 

In order of most preferred at top to least preferred at bottom:

 

1. WLG->AKL->JFK/ORD->BOS (hypothetical of course)

 

2. WLG->AKL->HOU->BOS

 

3. WLG->AKL->SFO->BOS

 

4. WLG->AKL->LAX->BOS

 

Primary reason for this ranking? Spending as little time domestically on US carriers as possible. More than happy to pay more for less time on United or AA.  JFK is such a pain of an airport to enter the US on though, so it would be a toss up between JFK and ORD (Boston is just as bad, but by then its a domestic flight).  Layovers in CA can be brutal too (11hrs+), with only a couple of coast-coast flights to Boston.

 

 

 

I have family doing the run next week and they've been told by AirNZ to not expect any disruption which is great.

Today's update:

 

 

Auckland Airport operations are returning to business as usual as progress continues to be made restoring supply via the fuel pipeline, Energy and Resources Minister Judith Collins says.

 

“The fuel industry remains cautiously optimistic as solid progress is being made. The pipeline will be operating at its current allowable capacity from late today and jet fuel allocations were increased from 50 to 80 per cent effective midnight last night,” Ms Collins says.

 

“Two million litres of jet fuel has now arrived at Auckland Airport’s JUHI storage facility, and 15 million litres is expected to be available by the end of the week.”

 

Trucks have begun transporting jet fuel from the 1.5 million litres stored at Wynyard Wharf, and jet fuel continues to be trucked from the Marsden Point refinery to the Airport.

 

“Stocks of both jet fuel and fuel for Auckland motorists are replenishing. In the coming days the fuel industry will be looking at the sequencing of different types of fuel down the pipeline. This takes us a further step toward normal supply.”

 

“While the situation is improving day-by-day, there continues to be a lot of work going on behind the scenes. I’m particularly impressed by the way industry has worked together to minimise disruption as much as possible.

 

“Government continues to be closely involved in monitoring the situation and remains on stand-by to provide further assistance if required,” Ms Collins says.

 

“It may be another week before the allocation to airlines is back at 100% but they are doing a great job at managing this constraint.

 

“Flights in and out of Auckland Airport have now largely returned to normal operations, with only three international flight cancellations today. No domestic flights have been cancelled.”

So much for a fossil fuel free future. I can't see no electric planes taking off any time soon.

ONE flight out of New Zealand to any other continent probably uses more fuel than my family's entire fleet of cars in our lifetime combined

Reminds me of a story I heard a few years ago. Brad Pitt (think it was him) was driving a hybrid car while at the same time he's got a private jet. Now which one produces a huge amount more Co2?

That would be right. There are plenty of 'liberal elite' Hollywood types virtue signalling about poverty and global warming while swanning from one party to the next in their private jets and helicopters.
