The moth-evolution-story in the beginning is often told in school (where i learned it) but has actually been disproven by biologists - which i learned in university where this study is used to showcase how a seemingly logical explanation was being disproven and still told in schools. It's an example of both: scientific scrutiny in biology and the sedate nature of the educational system in biodidactics. It seems like a logical explanation and thus took a while to figure out: But actually the moths for the most parts weren't resting on the bark of tree and didn't have an advantage by their new camouflage. There are some theories about what actually happened - here is my favourite: Industrialization changed the air's humidity which changed colour-deciding factors in the larvae-state and thus the darkening of the moth's colour did coincide with the darkening of the trees because industrialization caused both.

If I'm not wrong you didn't explain the carbon capture process completely. You NEED ENERGY to convert CO2 back to hydrocarbons.

[@Josef-K.]

I was wondering this too. And by the 2nd law of thermodynamics, wouldn't you need to input more energy to create the fuel than you get back out from burning it? Why not just use the renewable energy directly instead of temporarily storing it in fuel? E.g. use the renewable electricity to power electric cars instead of burning gasoline, sequestering the carbon, using even more electricity to make more fuel, and burning it again? Am I missing something? There are a handful of applications where it's hard to replace hydrocarbon fuel with heavy batteries. Aircraft. Military vehicles. Maybe shipping?... I'm at a loss to think of much else. So these synthesized fuels would have their place. But shipping, air travel and the military are a modest part of the carbon problem.

[@svenneidig7624]

Koray Armstrong-Sahin I agree with all your points. I watched the video for some answers. Hydrocarbons are not bad, fossil hydrocarbons are the problem. In the end we have to talk about energy flows. We use a (fossil) energy stock right now, this is not sustainable. And I don’t think that Carbon capture changes the basic dilemma. We use a lot of energy and harvesting this energy will cause entropy somewhere somehow.

Not really. If forests were sufficient to solve the problem, we wouldn't have had a problem. And we're reducing their capacity year by year as we cut down more and more of it. Even if we could somehow convince the world that "don't use wood" is somehow easier than "don't use oil," forests are already well past their prime as a carbon sink, and even if we replanted all the forests that we've ever cut down and then some, they take 1000 years to grow back -- far too slow. Things like algae farms, cyanobacteria culturing and the such however are valid options for carbon capture systems. I don't know how they compare to the chemistry-based system noted here (in terms of either cost, efficiency or usability of the output products) but they're definitely being researched as alternatives (by different companies of course.) Trees though.. they're way too inefficient to compensate for our fossil fuel addiction.

FORMULATED MICROCRYSTALLINE WAX WILL CAPTURE CARBON The heat loss from a smokestack can be forced into a large tank containing hot liquid microcrystalline petroleum wax. The heat will keep the wax at a molten state which facilitate the carbon to be absorbed when combined with the wax. Carbon when mixed with wax reacts like a dye. The wax-carbon amalgamation resulting in a black wax solution thereby making it impossible for the carbon to escape into the environment while in a liquid state. Other toxic particles are also captured in the wax settling at the bottom of the tank forming into a sludge. A sludge release valve is located at the bottom of the tank. After the sludge is removed more wax is replaced in the tank working something like a toilet. The sludge becomes a byproduct that can be used as an additive to asphalt for roads or used for cocooning nuclear waste materials for long-term safe burial. The entropy of the Earth has been increasing at a startling rate since the beginning of the industrial revolution caused mainly by the carbon that is released into the atmosphere. Government scientists have failed to stop and prevent carbon pollution from entering the environment. This problem can only worsen until a solution is found before this problem becomes irreversible. It has been discovered that formulated wax has been shown to be the only answer to this problem. William Nelson [e-mail]

History has shown that the main competitors, socialism and communism, have not only failed at producing "lots of stuff" but also failed at producing the good useful stuff youre referring to. They've led to the overproduction of outdated tech and consumer goods that arent in demand and the deficit in goods that arent just demanded but needed by their society. Capitalism will be the cause of the solution. Itll likely be engineers who apply new discoveries by chemists, to create a cheap way of converting pollutants into something profitable, in the name of making money. We already have more than enough solutions out there, its just that all of them are big cash sinks (and no, in a non capitalist society, those solutions wouldnt be easily implemented either). I think you forget just how much the idea of making a profit drives R&D, aka, scientific and technological advancement, the thing that has fixed most of humanity's problems, across history. As it is with all things like this, even though "evil greedy capitalists" are the cause of this issue, and even though its an issue thats raising alarm now because of what could happen in the future to us, we just wont get to a point where we're screwed. Someone will come up with a viable solution by then, not just something that works at the cost of an arm and a leg or some ignorant non-solution like "just plant more trees", but something that gets the job done and can run without being in the negatives. It is the best viable system we have as far as the results have shown. You can talk all you want about the negatives of capitalism or how many problems it has caused, but looking at the bigger picture, it has a net lead on the other systems we've thought of. The only argument you can make is that real communism has never been tried (but thats just because the method of implementing it isnt viable in the real world). I get to say all of this because im in the field.

The biochar locks in carbon for thousands of years while also being able to potentially double yields of carbon depleted farmland. Biochar can also be used for other purposes like filtration. Better grazing practices to reduce soil degradation and thus carbon dioxide (among other things) emissions. Zero-till: not ploughing to turn over soil as not to expose humus that can then rot and release carbon. Making grasslands Reduce deforestation and turn 'slash-and-burn' agriculture to 'slash-and-char' All of these can be done at a much lower cost than some of the techniques featured in this video.

You probably can't fully conserve the chemical energy from the fuel when it's burnt or even when CO2 is captured, you spend at least some extra electricity/energy in the conversion, and burning this renewable fuel that you've made also releases heat energy which you can't capture (eg excess heat radiated from a car engine into the atmosphere). At a minimum you'd use energy to turn the fans/pump that sucks in the air, which could potentially still release CO2 - not to mention the upfront production cost (in released CO2) of the materials/plant itself.

[@Darticus42]

They're a solution, but not a perfect one obviously A zero-carbon emission is impossible in this case, but if these carbon capturing plants can be powered using mostly renewable energy then you're taking out more CO2 than you're producing to capture it, and so the total CO2 when including the fuel it produces is closer to carbon-neutral than just taking oil/coal/gas from the earth and burning it. Besides, once we start to run out of natural reserves, this "artificial" oil could give some buffer room to prevent market disaster while researching better alternatives *cough* nuclear fusion *cough*

[@Suedocode]

@@Darticus42 There's no way to use CO2 generating power (i.e. coal or fossil fuels) to pull out even close to an equal amount of CO2 from the air. You need an external energy source like light (i.e. plants & algae). But if you're using that, why not just generate power directly through solar rather than waste time, resources, and energy with this proposed conversion process.

[@Darticus42]

Suedocode that first part was kinda my point. If people go through with carbon capturing we should rely on renewable energy resources to power them, not CO2 generating power because it gets it *closer* to CO2-neutral (it's not close yet but it's promising). And it's certainly not viable as a long term solution because it still releases more net CO2, it's a potential alternative while we still rely on natural oil/gas/etc.Other, more sustainable, alternatives like wind & solar do not have a very predictable and consistent output so you end up needing to either store excess energy to get you through a "dry spell" or connect to the grid which ends up using CO2 anyway (and that CO2 would never get taken back out). So it's not like those solutions are going to be that much better either.

The best carbon capture is vegetal growth. Using bamboo instead of steel to build classier office buildings might be a good start.

[@invalidusername7857]

Just a thought.You know the saying: to pull "something " out of thin air? Well... If we utilize carbon capture to take carbon-dioxide out of the air and then use the carbon in making synthetic diamonds? Then we will have successfully made diamonds out of thin air.

[@fortunefed8719]

I have to disagree. The air would be pretty thick, not thin.

[@solarshado]

I was thinking along similar lines. Why turn the captured carbon back into fuel instead of something else? I was thinking of graphene, not diamonds, but either option seems better in the long run than fuel. Even plastic seems like it'd be a better option, assuming recycling it's cheaper than the atmospheric carbon capture process.

[@danielhughes6896]

Most carbon capture programs I have seen, propose using the carbon for something that will just result in the C02 being back in the atmosphere, for example using it in the beverage industry (drinking the drink results in the C02 being release). Some fossil fuel industry suggest pumping it into the ground to force out the hard to get oil. This also result in more C02 in the atmosphere.

[@heckler73]

Do you have a video explaining why you believe that CO2 is a "pollutant" ?

[@M33f3r]

@Ian M God is proven by the Bible just as much. It would be great if you could get access to the accurate data. But faith in the religious belief calling itself science is good enough for most people.

[@heckler73]

@Ian M the word in question is POLLUTANT. This thing you call "climate change" is not what I am asking about. What I wanted to point out is that CO2 is extremely beneficial for maintaining and creating an Earth with abundant produce. So, if he wants to call it a pollutant, and then demand I pay for his illogical premise, then I want a better explanation as to why he defines it as such. You can cease your hyperventilating now.

this is so weird , why go this route when a simpler route would be just use algae biofuel and have a same outcome.

Like he explained, this is just "a tool" in our toolbox to fight climate change. Algae biofuel is another option, but it hasn't so far grabbed the attention of investors, since it wasn't immediately commercially viable.

[@jimyarbrough9935]

Except we are producing more carbon faster than all of the plants in the world can handle. An avarage American would reguire over 900 trees to absorb their carbon foot print. We cant plant enough trees at this point, we gave to reduce carbon production and lower the carbon in our environment.

[@cavemann_]

We need it all. It's not as simple as you are making it out to be. Not only do we need to go carbon neutral, we also need to suck it out of atmosphere to mitigate all the damage we have caused, and even then it will take at least 30 years to go back to carbon levels from before the industrial evolution.

[@f3derico2007]

Second principle of thermodynamics: you cannot decrease entropy in an isolated system. Which means you cannot convert CO2 into fuel without creating more entropy, i.e. more CO2, than was initially present. One could argue that renewables could be used. But then why not use renewables in the first place and skip a step. There is another problem, the scale of the carbon capture plants would have to be titanic in order to have any effect on the net balance. Carbon capture is more inefficient than carbon production, so imagine for every car, jet, power plant we should have a much bigger carbon capture facility, and renewables to power it. It does not scale.

[@julienkuzdzal6081]

Agreed. There is no clear idea* regarding the actual carbon footprint of such a process i.e. the ratio of CO2 released into the atmosphere (caused by the energy needed for the fans, the chemical processes, hydrogen production, plant construction, etc) v.s. the CO2 “captured”. This ratio could be interesting if the plants run on renewable and/or nuclear energies. *EDIT: I found in source #16 that the plant uses 8.1Gj of natural gas energy input to capture 1 ton of CO2. And producing 1Gj of energy with natural gas releases 56kg of CO2 in the atmosphere (value found after a quick research) So one can calculate that to capture 1 ton of CO2, 450kg of CO2 have been released in the atmosphere burning gas to power the plant. And this does not include the energy needed to transform the CO2 in fuel.... (or my calculation is wrong - or I misinterpreted figures of the source..?) Hence my skepticism regarding what they call "carbon neutral fuel” - like you said, that is just not possible (did I hear someone say greenwashing..?) And I doubt too regarding the feasibility of a large scaling of that kind of project implying the large scaling of renewable/nuclear power plants that must go along, with the rarefaction of various resources related that we know of. “Why not use the renewable energies in the first place” well because we still haven’t much figured out how to run cars/trucks/planes [on a large scale] on something else than fuel, I guess because of its extraordinary power density.

@@Rastafa469 maybe..? I don't know the numbers to be able to say whether hydrogen fuel would be more efficient. I know producing hydrogen is a process that demands a lot of energy.

The problem with just using renwables is you don't have control over when you generate power, that is a problem we can't ignore. Carbon capture can be the answer to our current energy storage problems. Think of the synthetic fuels as just liquid batteries.

Why don't they skip turning calcium carbonate into carbon and just sell the calcium carbonate (limestone) to construction companies? Therefore storing the carbon in buildings.
