    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%.

      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).

        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.

          This is just wrong, except if you live in some theory reality. It’s like saying if a car can go a hundred miles in a hundred years it’ll get there.

          There’s a reason why people don’t build small dinky toys like this and efficiency is why, anong other things like that pesky “cost”.

      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.

        None of the things you’ve described increase the carbon output.

        What chemical reaction gets more carbon out than it puts in?
        (Where do these new carbon atoms come from, fusion?)

        If anything, those other products include non-gaseous compounds which sequester the carbon from the fuel into a solid resulting in a net-negative amount of carbon being released into the atmosphere.

        Those side-products are not good, I’m not saying otherwise, but they are not additional carbon.

          So replacing their gas with carbon neutral gas will improve the situation by 100%.

          Referring to things as carbon neutral is typically shorthand for net neutral CO₂e (or net-zero) CO₂e.

          You’re pedantically right that the machine is not creating or destroying carbon atoms, but the things it does create have massive “carbon dioxide equivalence”. Or, phrased differently: the emissions of this equipment are equivalent to emitting significant amounts of carbon dioxide.

          They also reek havoc on people’s lungs.

          This is worse than air, but better than doing nothing I suppose. The situation is not “improved by 100%”. It’s marginally better, but definitely not 100%.

            Eh?

            You take excess green power and use it to generate gasoline. You use that gasoline in a combustion engine. Where is the extra carbon coming from which makes this non neutral?

          Right. Because none of it is a fucking coal mine. Which is the only thing that can provide “carbon output”. Except a diamond mine, of course.

      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.

        You can vote me down as much as you want. You still have no clue of chemistry - or anything else you’re babbling about. Morons.

        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.
