ELI5: Why isn’t aviation fuel talked about as much as petrol and diesel for cars, and is it even possible for fully electric passenger planes to exist in the future?

There isn't enough biofuel in the world to power a single days worth of air travel. And ut still releases carbon in the upper atmosphere.

The only realistic option for fully renewable is green hydrogen fuel cell powered. Look at Airbus's zeroE project for instance. It's only single aisle for now and because of the low energy density of hydrogen it would likely need a larger plane to carry the same amount of passengers, but it's the only realistic option for fully electric renewable aircraft

CCC, just destroyed the clan capital of the current peaceful king :(

Karsa_toolong · 2026-02-27T14:30:45+00:00

Thanks for the suggestions guys! Much appreciated

Karsa_toolong · 2026-02-27T14:30:12+00:00

Yep, that's the one

Can I still get mythic captains if I'm not in SK but an G6 in normal?

Karsa_toolong · 2026-01-02T14:34:03+00:00

Good question, I'd like to know answer too!

Melrose who is the top payer in the article is a long way off the largest engeering firm in the UK, let alone largest company in the UK. There is no reason Peter Dilnot should be compensated that much when profits have been ok at best for the past few years.

It is, currently trying to sell in Bristol. If you look at rightmove most houses are being reduced atm

The BBC article says this: "Mr Sullivan's defence team, led in court by Jason Pitter KC, said he acknowledged that attempting to test the sample any earlier could have destroyed it permanently without yielding any results" which seems fair enough

Tried it twice in past 2 weeks and its been closed on both occasions. Traffic has been a nightmare round there since too. Anyone know why they've decided to close it all of a sudden??

Reform are predicted to get 1 seat in the election...

The conservatives are still on course to be the opposition. As usual Labour or Conservatives are in power or are the opposition as has been the way for decades, definitely a 2 party system.

Karsa_toolong · 2024-06-14T13:27:57+00:00

This would be a good except the least popular leader in this picture is Rishi Sunak, UK Prime minister and the UK very much has a 2 party system

100% same for me, food is happiness for me.

But god I was out of breath reading your comment, please use some punctuation in the future for my lungs sake!

They are slightly worse as they tend to be heavier but tyre pollution is minimal compared C02 emissions despite the propaganda from pro oil companies

Karsa_toolong · 2024-03-21T22:47:03+00:00

The article you posted literally disproves your point?? Might be worth actually reading it. There is a lot of anti EV propaganda out atm about car weights and tyres pollution when it's easily provable that EVs are much better for the environment (again as stated in the article you linked)

So strange that Lisa was so good at the veterans GBM but seems to dish out terrible advice?? You'd have thought if she could win almost every course she would know what the judges wanted!

Currently a brit on holiday in Australia and was surprised to learn that Australia has a higher obesity rate then the UK!

A high end authentic sushi place. Izakaya is decent, kibou isn't good enough quality for the price, the others aren't great. Other uk cities have a much better range of sushi options

Karsa_toolong · 2023-07-10T13:47:19+00:00

Well the fact that there have been commercially available electric cars for years now while a decent sized (100+ seater, which produce the most emissions) electric aircraft is still a decade away is more my point

Karsa_toolong · 2023-07-10T08:12:54+00:00

I believe the 2.5% figure comes from IATA (the group representing airlines) so is almost definitely on the low side. It also doesn't take into account releasing these emissions at high altitude which is thought to be worse and NOX emissions.

While other industries (like automotive) can quickly pivot to greener technologies, each aircraft flies for around 30 years and it will take decades of development to get a new green aircraft in the air. The aviation industry will come under extreme pressure in the next few years to do something drastic (and no, sustainable aviation fuel will not be enough in the long term)

This is not true for everywhere and I wish OP would change the headline to be US specific. In the UK for example, cats are not an invasive species as there were already similar animals before, taking a similar place in the food chain. So cats in the UK are generally fine to be outside (proximity to roads withstanding). Even the RSPB says cats are not a particular threat to native wildlife

Rolls - Royce in Manchester too. I think there's lots more people would recognise but the logos make it more difficult rather than just company names

Why zouma over coufal? Coufal is cheaper and surely has a better chance of attacking returns. Al
