      honestly I think that the turning of co2 into fuels is, at least at this point in time, one of the best ways we have to store energy and for transportation. it may not be the most efficient but the biggest problem with solar and wind is that we need to find ways to store the energy from peak hours to use at non peak hours and batteries do not have enough energy density to do this on the scale we would need, even solid state batteries probably wont be enough. I honestly think nuclear energy is the way to go for energy production but solar and wind are not without their purposes, we just don't have the technology or infrastructure to rely solely on wind and solar like many people want to.

    So most seaweeds are algae. Why aren't they being used for CO2 capture? It seems like it would be far more efficient to throw a few 10s or 100s of millions at kelp reforestation than to try to roll out and scale brand new tech before the 2030 deadline. Also, the urea issue sounds like a ridiculous consequence of our current industrial farming methods. We farm cows and other animals in factory farms producing tons of environmentally-damaging "waste" which includes vast amounts of naturally-produced urea. And most farms still don't cover crop. Wouldn't it be faster and more efficient to reduce urea's environmental impact by subsidizing cover cropping, and figuring out how to get the livestock (or at least their waste) and plants back on the same farms so less needs to be manufactured? I'm also really skeptical of the impact of any new process that requires palladium and titanium. They're both pretty energy-intensive to produce.
    That said, the jet fuel recycling sounds promising-at least more so than trying to fly passenger jets with batteries, or reviving the dirigible industry. And it's hard to complain of reducing clothing in landfills.

      With the exception about plants. As plants typically do not intake CO2, but instead CO.
      In basic biological function, the lungs strip a single oxygen molecule from CO2 to oxygenate the blood. There are other things necessary for this process, and some of those things are also classified as "bad for the environment" or as listed causes of global climate change.
      The issue with climate change is that climates ALWAYS change. It is part of the nature of climates and why most biosphere attempts fail.
      One must also understand that climatologists are mostly only utilizing recorded data, and we havent been recording climate data for that long, less than 140 years at that. Yes I understand that we do perform Glacial Core Tapping and Extrusion, however that is still classified as an 'inaccurate science' by climatologists themselves.
      We also have mathematical proof that the Earth is moving closer to our Primary Sun due to how the orbit and gravity functions in Space. And we know for a fact that this has an effect upon the Global Climate.

    Hank, perhaps you are well intentioned, but I feel that videos like this take our collective eye off the ball. At present and in the foreseeable future, we create more CO2 in the generation of the energy used to take CO2 out, even with new technologies. On the other hand, any technology that uses non-CO2 emitting sources to generate energy or produce useful materials acts as a net carbon sequester technology. These include solar and wind generation, but also nuclear, hydro and even production of wood and bamboo based building materials. You don't have to count CO2 molecules being actually sucked out of the air, you want to lower the amount of CO2 produced to drive our critical industries (agriculture- fertilizer, electricity- fossil fuels, concrete production, personal transportation).

    Finally some more good news! Something that is not only good, but potentially also profitable, so there's way more of an incentive (even for people that wouldn't care otherwise)
    I personally think the holy grail would be to convert CO2 directly, into Graphene or even better nano-tubes. We need to make all the new additions of CO2 neutral.. but we also need to remove some of the current surplus, by either putting it underground (like the "dinosaurs") but converting it into structural materials is probably more useful.

    There's something out there that is already very good at extracting the carbon from CO2 and storing it... it's called PLANTS. To reuse CO2, just farm fast-growing plant fibre crops, mulch and compress into bricks, burn those bricks in power plants for electricity, use battery vehicles. Wood/plant fiber is not viable in vehicles because it's not that energy dense, but you can burn it in a power plant no problem, the energy/weight ratio isn't an issue there. All the CO2 you're using came from the atmosphere, you release it back into the atmosphere, your crops continue pulling it from the atmosphere, no new CO2 is ever added, a balanced system.

    A circular carbon economy, or carbon-neutral economy, is a great principle. Unfortunately, we've spent decades and hardly made a dent in either of the big components - effective carbon capture / sequestration, and efficient carbon reduction (the actual recycling part). It's great to see continued developments, but we also need to be looking at carbon-free economies, which include carbon-free fuels - most likely hydrogen and ammonia. As much as removing CO2 from the atmosphere is a necessary step, it'll be even more important to reduce how much we emit in the first place.

      in reality you would get as like 70 ish % reacted products 5 to 10 side reactants and remaining unreacted products, so you will have to distill it to seperate the jet fuel and use it.
      thermodynamically speaking this is possible, but it's a very energy intensive process. because if you want to make 1 liter of jet fuel, then at MINIMUM you will have to provide the same amount of energy to make the exact 1 liter, but in reality there are so many inefficiency in every step, and the thermodynamic feasibility, so you will be using like 1.5 to 3 liter of jet fuel (using it in a gas turbine to produce energy for this reaction for ex) just to get 1 liter of jet fuel. in no matter what scenario u want, this is not economically feasible. it is possible with renewables, but they have their own problems in terms of industrial scale to provide sufficient and reliable energy to perform these 24X7 supply wise

    For DECADES now institutions have been discovering new technology year by year that solves "insert serious problem here", but guess what, 99.9% of them never broke through or only marginal.
    And that is because it's either too expensive, doesn't work on a large scale, needs too much resources, is not efficient or even better, not commercially viable.
    It was like that in the past, it won't change in the future.
    People should stop thinking that new technology will save us someday somehow. It is a great tool in some areas don't get me wrong, but it will never be the definitive solution to the climate crisis.
    This is what we can do instead:
    Expanding on technology which already exists like solar or wind energy, Pumped-storage hydroelectricity etc. to make current demands carbon neutral.
    Establishing better concepts for transportation which already exist like a walkable/bikeable neighborhood, public transit, high speed rail etc. to make cars and airplanes less necessary.
    And just generally consuming LESS, not eating too much meat, not buying the new IPhone every year, not leaving the lights on 24/7, buying more second hand products etc.
    THOSE are the things that will truly stop the climate crisis.
    And I know what you think: The video title says "ONE way to deal with CO2". Of course it wasn't meant to be THE solution.
    Well I'd say the same thing, but he then just doesn't list the alternatives e. g. at 4:37:
    "We could theoretically create a circular carbon economy around air travel and make vacations a little more guilt free in the process"
    Completely ignoring that the best solution would be just NOT TO FLY. Why not suggest other types of transit like trains?
    (and yes I know sometimes flying is the only option, but imo you should still bring this up)
    But what bothers me the most is the fact that he ignores the many problems that come with actually utilizing new technology, which I already listed above.
    He just gives people the feeling that they don't have to adjust their daily life after all and someone else will fix their problems.
    Just a little comment on that at the end would have been enough.

Green hydrogen (hydrogen from renewables) is good, but fossil companies are pushing for blue hydrogen instead (hydrogen from fossil fuels), which makes progress even slower

      @@wannabewallaby1592 And of course, there's approaches to deal with both of these problems - liquified hydrogen and even more interestingly, solidified hydrogen. But those are way too early techs to be considering serious contenders at the moment - there are more developed cutting edge batteries that still outcompete any vaguely practical hydrogen systems, but we'll see how all of that goes. The critical thing is not to close up avenues of research that don't seem particularly promising right now - we need as many options as possible.
      Honestly, even blue hydrogen is a huge step forwards. It still helps develop hydrogen infrastructure; it can still eliminate carbon dioxide emissions (that is, you can easily deal with the carbon dioxide in situ, rather than having to thing about carbon capture etc. - what exactly to do with that carbon dioxide is still tricky, though the option of pushing it back into the well to improve extraction rates did have some minor successes in some pilot wells). Heck, you can even store it as pure carbon, though that of course means wasting much of the energy in the raw oil.

      I'd guess that it's not viable to extract urea from human urine on a sufficiently large scale (there are already some sewage treatment plants that produces fertilizers as byproduct, in certain cases I believe, as most of the things being flushed are indeed compost). It's probably not viable to try and extract urea specifically from sewage, and redirecting urine away from sewage for this purpose specifically is likely also counterproductive.

      Of course. Just... better. Most trees and plants aren't particularly good at capturing carbon (they have lots of other things to do!). Heck, there are some really interesting results from combining photovoltaics with normal farming - the panels provide a relative shade, allowing the plants below to be more efficient _and_ reduce their water usage considerably. Human-made machines can usually beat life at highly specialised tasks, because our designs have many advantages that simply aren't available to a living thing.
      Does this mean this is the best way forward? Or the _only_ way forward? Of course not. We need a _lot_ of different solutions working together, not one cure-all snake oil. That's always been the biggest problem, whether you're talking about fossil lobbies (incessantly pushing for more fossil use) or your-favourite-one-in-all-climate-solution lobbies. Chasing the one favourite thing (whatever that is at the time) will always be disastrous.

    Before grad school, my fantasy was to engineer algae chloroplasts with decoupled photosystems which would evolve both oxygen and hydrogen instead of going 'all the way' and using the hydrogen to reduce the carbon in CO2. They would split water into a perfect combustion gas mix in some chloroplasts, and feed themselves with others- it's not there isn't already a number of natural plastid types in any photosynthetic organism. I hope someone's on it.

      @@capturedflame From my time working on GMOs in grad school (plant biochem- research not associated with this subject), my worry was always 'what would happen if they got loose'. I was mostly a lone dissenter. People looked at me blankly when I spoke about the need for GM organisms to have no ability to breed with native species or other crops we might not want 'contaminated' with 'junk' DNA- and a way to kill them easily. We've already learned how difficult some types of pollution are too clean up. Remember that 'smart' people did't stop to think we could pollute the lakes, rivers, oceans, and atmosphere. We did. I ultimately chose another path. The promise is high, but so are the dangers- those investing in research want returns so problems are hidden. But, photosynthetic lysis of water is so slow- any plant doing it 100% wouldn't be able to catch fire if you held a lighter to it in open air. The real dangers are so much harder to imagine because we're so much more ignorant than we like to believe*.

    Yeah sure wonderful thing BUT
    1) every single kg of co2 you emit needs to be taken out, so you would need to build a co2 scrubbing industry literally as large as all the other co2 emitting industries combined. All that while remaining within the current carbon budget.
    2) it assumes ALL the required carbon capturing equipment is powered by 100% carbon free energy and that their life cycle is long/efficient enough to have a net negative carbon cost, not to be literally counterproductive. Considering point 1, it means you need to have basically a second 100% renewable energy grid just to deal with the millions of tonnes of carbon emissions currently being produced.
    3) If the carbon is then used to produced goods and/or fuel, it will end up back into the atmosphere eventually, achieving parity at best assuming that all fossil fuel use is halted today. This is simply not good enough, as you need to have net negative. We will have to pump carbon deep underground, for no immediate economic or material gain. This is simply not something that can be profited on, the economy will not save us.
    So to summarise, great, carbon capture is great, but overselling it as a potential solution to all our carbon products is really harmful and counterproductive. It is a tool, sure, but major societal and economic changes still have to come now to avoid climate disaster. We simply cannot keep on going business as usual, hoping that carbon capture will make all problems disappear. Do not think like this.
    Also, a flight that long emits around 800kg of co2... PER PERSON.

      Go carbon negative for too long, the Earth cools and we go into another ice age. Simplified answer. I saw a video the other day. The Earth would radiate the heat it absorbed during the day back into space overnight. The greenhouse gasses are what keep that from happening so more heat stays in. Without which we would be like the moon. Scorching hot days and subfreezeing cold nights.
