much of which will soon be recycled...... Good for Airbus, but I do wonder where would these recycled aluminium go. There are not many info Airbus uses recycled aluminium for building aircrafts. Just to be clear, I meant the aluminium they have used on the A380 will soon end up being recycled.....

Well, only 21 A350 delivered this year so far, compared to 289 single Aisle aircrafts this year. A380 has about 61% aluminium, A 320 has 72% aluminium composition The A380 programme is as dead as a Dodo. Qatar Airways have said that buying them was the biggest mistake they ever made and they would love to get rid of them. Only problem is they cant't get any A350's to replace them. BA have a similar attitude. I think lots of airlines are regretting scrapping their B747 fleet during covid. They were old and inefficient, but did shift a lot of passengers. What was wrong with the 380 ? Not enough airports to land in?

Not enough airports to land in?If the demand had been there from the airlines, more airports would have provided the facilities. But the world had moved on, and the plane had some inherent competitive issues (production costs). The hub and spoke model while not dead, is less alive than the A380 was designed for and needs to be competitive. It has also ended up with less efficient engines than say the 787. In the end, it was the wrong plane at the wrong time.

perhaps Boeing used recycled aluminium for the door bolts or PlayDoh Oh, 777X. On paper, it looks great on efficiency. Would it end up being like a disaster like the 737-max? more efficient than A350 series. Can 777 really be resigned for extra wide body?

They were old and inefficient, but did shift a lot of passengers. What was wrong with the 380 ? Not enough airports to land in? When the A380 was designed all long haul aircraft needed 3 or 4 engines to get to their destination and most airlines were looking at hub and spoke networks. Fast forward 35 years and lighter aircraft materials and more efficient engines mean that an A350 can fly the best part of 2000 miles further than an A380 at a much cheaper unit cost. Back in the 1980's I worked in Hong Kong and aircraft couldn't make the 13 hr journey non stop. Now Singapore airlines fly non stop from New York to Singapore in an A350, which is a 19hr trip.

Now Singapore airlines fly non stop from New York to Singapore in an A350, which is a 19hr trip. and they almost certainly needed to build the planned for A380-900 stretch version to make the economics work. It they ever could have. The base A380 was "built for" the stretch version, but lack of demand thanks to the competition once it got to market meant the -900 never got built and the base version was carrying too much weight etc. to be competitive. When Boeing made the decision not to produce a 747 replacement while Airbus piled in to the A380, many pundits thought Boeing had got it badly wrong. In the event, they got it right but whether that was fortuitous accident or not is another matter. Thankfully for Airbus, under some pressure from customers they also put a load of investment and effort into the 330 and 350.

“Turning electronic waste into gold: The Royal Mint brings world first sustainable precious metal technology to the UK”
Has anyone been hoarding old electronic waste? You could have a bit of undiscovered gold mine. 🤣

On no real hard numbers evidence, it's blowing a gale over the whole UK and looking clear sky's and sunny in the south. So could we go gas free for a short period today, I do not think so more probably because the management tools of the grid are not ready yet to risk free go for it. However a record high of green generation may happen.

Not going to happen looks like favourable weather conditions were used to crush out imports of electricity , however if it had been a Sunday with reduced commercial consumption I think we may have made gas free.

Looks like CCGT hit 10min average of 5% for a good chunk of the day, though. Even now, nearly 9pm, it's only 20%. At a rough scroll, last year's lowest day was about 7%, but <10% was the definite exception.

Yesterday finished up at a daily average of 11.5% CCGT.
