Craig: so lots of startups are trying to save the world via ocean geoengineering. what's going on here, john?

Jon: yeah. this is cool. so, it's not just one startup, but there's multiple startups that are developing technologies to leverage the ocean's natural carbon absorption capabilities to help combat climate change. so there's companies like captura, running tide, and aquatic that are at the forefront of this field of marine carbon dioxide removal or mcdr. so what they're doing is they're employing different approaches from growing kelp forests to developing electrochemical systems that extract c o two directly from seawater. so for example, captura, they've developed a system that uses tightly focused beam of light to capture and manipulate microscopic particles in seawater, which is essentially effectively removing dissolved c o two. whereas running tide is exploring the cult the cultivation of kelp forests on biodegradable buoys, allowing the kelp to absorb the c o two as it grows before sinking to the deep ocean floor. and then finally, aquatic, they're combining co two extraction with green hydrogen production, my favorite, addressing two critical climate challenges simultaneously, which is cool. so, it's gaining momentum. there's significant funding and support from both private and public sectors. the xprize carbon removal competition and the us department of energy's carbon dioxide removal purchase pilot prize have included marine based strategies among their finalists indicating that there's a real growing recognition for, using the ocean to capture carbon. but the critics are saying they're warning of potential risks to marine ecosystems, and they're also questioning the long term effectiveness of such approaches. so, the london protocol or london convention, they've called for careful evaluation of these marine geoengineering techniques. so, i don't know. what are your thoughts on this, craig?

Craig: i am excited about anything that's gonna clean up our waters and clean up our world, actually doing the cleaning. i'm not excited about startups that are injecting crap into the air to do stuff because that we have no idea what it's gonna be. but if we can take, stuff out of the oceans and make them cleaner and better, i think i'm all for that.

Jon: yeah. as long as it doesn't disrupt marine life, which, again, the thing, the thing i think that a lot of these companies, they forget is, like, they forget about the marine life. all they focus on is everything above water. the, i'm glad that there's investigations happening and evaluations happening to make sure that, there's not a huge impact on the marine environment.

Craig: yeah. and i guess the question is, why are we, why are we removing carbon from the ocean?

Jon: because we've got too much carbon, i think. and the the ocean is one of the largest carbon capture, ecosystems. other like, i think it captures more than trees. i could be wrong. and, guys, you'll, you know, roast me in the comments. but, i think it in order i think what they're trying to do, and i haven't done my research on this, but could be because to allow the ocean to capture even more co two because we're just creating way too much co two.

Craig: yeah. and i guess i have to understand if it's one of the biggest capture things, why are we taking it out so it can capture more? are we taking it out because the cycle of water to cloud vapor to rain, is making the co two come back into our environment. like, if the water is naturally there to absorb the co two, are we saying that, it's hurting the water life ecosystem because it has too much? i, i'm okay with all this. i just don't understand hundred percent how the whole system works to be able to pick apart those pieces that i really like, what i don't like just from a yeah. why specifically are we doing this?

Jon: yeah. so there's a few reasons why we're doing this. so thank you. we're we're looking, to enhance the ocean's natural carbon sink. so the ocean already absorbs about twenty five percent of all carbon dioxide emissions. so by removing c o two from seawater, we can increase the ocean's capacity to absorb more c o two. so i was right. i'm by the way, i'm using perplexity to give me this answer, from the atmosphere, which effectively enhances its role as a carbon sink. the other thing is mitigating ocean acidification. so as the ocean absorbs more co two, it becomes more acidic, which threatens marine ecosystems. interesting. didn't know that. obviously, adjusting, climate change. and, yeah, because the last one is leveraging the oh, no. there's six. so leveraging the ocean scale. so the ocean covers seventy percent of the earth's surface. it holds forty two more carb forty two times more carbon than the atmosphere. so that means that the ocean based cdr methods, if proven safe and effective, could potentially remove billions of tons of c o two per year. and then there's some other ones that we already talked about. so, the other thing too is we need to restore the ocean's chemical balance, because of the acidity. so there you go.

Craig: and that i understand. yeah. where does the carbon go when we extract it? where do we put it? yeah. that's a question. do we know? i didn't see that in, this is a process where they take it out of the water. what do they do with it? do they put it in natural aims to just climate change by enhancing natural carbon sinks? alright. anyway, i like the idea of all of this. sorry. i have more questions than answers on some of these. and i think the more startups again, you know, startups are stuff we love to work with, and they tend to move faster than big companies and try a whole bunch of different things. i'm really interested in seeing where some of these go. so, i like the bubble curtains that mitigate hurricanes and, another carbon capture. i'd like, leveraging kelp for carbon sequestration, so that's an interesting, way. again, if the ocean alkalinity is changing because there's too much c o two, then that's definitely something we wanna be looking hard at. and over time, what was the c o two in the ocean, a hundred years ago, a thousand years ago, and what level does it need to be at to get our fish thriving, you know, and that ecosystem has the right balance. like you said, we gotta make sure we don't impact the ecosystem. and different ecosystems might have different levels of co two they require, which might be a delicate balance. but, again, same thing when we're putting out, those windmills out in the ocean or on islands. they have an impact on, the fish and the whales and whatnot. good at it. seem to be happening. at least there's research into that. and i think that's why they're stopping to put the poles in the ground and building those islands so they don't have the same effect because we were talking about that man made island they're building and putting all the powered windmills on that rather than sticking them directly into the, water. i think those are different aspects of, can we try this? we understand there's an impact on the ecosystem. let's try this other thing and see if there's less of an impact on the ecosystem so we can change. these things are always great as long as we are keeping those things in mind that we have to really look at the negative impact versus the positive impact and making sure, overall, the world is becoming a better place by what you're doing.

Jon: yeah. absolutely.

Craig: can you hear me any better?

Jon: yeah. much better. something?

Craig: i didn't do anything.

Jon: yeah. you're back to perfectly now.

Craig: so here's a question for you, our great audience out there. as ocean geoengineering pushes forward, potentially reshaping our relationship with the environment, are we stepping into a new era of ecological responsibility or sailing into uncharted waters? let us know your thoughts, and stay tuned as we continue to explore the fascinating world of tech innovations transforming our planet.
