It’s not worse. It’s carbon neutral (as long as the energy source is renewable like the sun). Any carbon it takes in will be released exactly back to where it was. It’s a much much better option than digging up oil.

On top of that, there are currently no likely possibilities of replacing gasoline for things like planes. So replacing their gas with carbon neutral gas will improve the situation by 100%.

Any carbon it takes in will be released exactly back to where it was.

Except it won't be. Combustion is not a perfect CxHy O2 > CO2 + H2O reaction. Theres a bunch of other side reactions happening, NOx, unburned hydrocarbons, particulate matter, carbon monoxide. There are lots of challenges to continuing to utilize hydrocarbon fuels, especially in mobile/small scale applications where you can't clean the exhaust stream.

The particulate matter won’t occur in a hydrocarbon that is generated, that comes from imperfect processing of crude. If you pull the carbon directly out of the air there are no particulates.

But yes it will still be carbon neutral. No additional carbon will be released back into the atmosphere.

For planes there's a catalytic process that can turn ethanol into jet fuel.

Battery electric aeroplanes aren't as far off as you might think, but you're technically correct that they don't currently exist.

[-] tyler@programming.dev 0 points 1 week ago

No they do exist! But most scientists agree that we are unlikely to ever see commercial airliners using it, nor will freight liners use it. We would have to see ENORMOUS scientific improvements and many many many things that seem incredibly far fetched invented to get to that point.

You overstate your case, several firms are already at various stages. Wright Electric is working on a >500km range passenger craft for easyJet right now. That won't be able to fill every role, but a worthwhile number of them to be sure.

If you could link that it would be great. As far as I understand it, a commercial passenger plane (which holds several hundred people) is no where close to being possible. If you are talking about small planes that hold maximum ten-15 people then sure.

There is no such thing as "carbon neutral". Nor is there a problem with carbon. You're talking about carbon dioxide which is as close to carbon as table salt is to chlorine.

Yes it is. And nowhere is stayed how efficient it is (only their "target" which is worth less than toilet paper because it isn't true).

[-] tyler@programming.dev 1 points 1 week ago

The efficiency doesn’t matter (to a point of manufacturing solar cells, or wind turbines, or whatever your equipment is for your renewable energy source). If all of the gasoline is generated from the air using renewable energy, it could take 100x the energy and still be completely carbon neutral. Carbon neutrality is based on the amount of excess carbon added to the air. If no carbon is added then by definition it’s carbon neutral.

Porsche already has a factory in Chile that is doing this exact same thing at a much larger scale.
