Hemp conversion to graphene and diamond. Smart carbon capture?

Hemp has been celebrated and vilified in equal measure over the centuries. It has fantastic properties for textiles and ropes, but it comes from the cannabis plant, so it arouses deep suspicion among some policymakers. What is unarguable though, is that it is an extremely fast growing plant that stores a large amount of carbon. So is it really possible to convert it into graphene and diamond in a sustainable, environmentally friendly way?

  1. Hemp is one of the few thing which will grow on land damaged by strip mining for coal. Transmissioning the coal industry to hemp farming is one of the easiest steps in a just transition to a post ff future. Paula Jean ran for senate in West Virginia with this a part of her platform. Unfortunately she didn't win

  2. Its really good to think about carbon capture. I appreciate everything you said in the video. The only thing I have contention with is you last statement about "jobs for our kids". Isn't it about time we had a think about what a job is and why jobs (as described in our capitalistic society) are just as damaging as the carbon we pump into the air. Jobs in our world, with the very very high percentage of people who hate their jobs, make us into sociopaths yearning for an apocalypse of some type to break our endless loop.

  3. It's a shame a lot of manufacturing companies don't put their factories underground. Hydroponic warehouses would be suitable for underground siting and would save precious house building space above it?

  4. it's nice and all to present how much CO2 they plan to potentially capture, but how does it compare to the amount of energy they will have to use for all their systems?
    as most vertical farm, i would suppose they will require artificial lighting to grow their hemp, and then comes the water pump/carbon capture system, the pyrolysis, etc.

    are you telling me they will also build hundreds of windmills and solar panels to feed their plasma reactor? because there is just no way they will have enough energy by only burning oils and gas from their own operations.

    TBH, this project just smells like some good old greenwashing scam.

  5. I'm from the southern US. Using this process on invasive species, namely kudzu, could provide a much needed benefit to not just the ecosystem, but the poor job market.

  6. Grass holds CO2 only until it decomposes within a week to months. The CO2 is then released. Hemp may last years but hemp clothing simply gets thrown away in 2 to 5 years. So you can only create a small CO2 reduction. My idea, and I am sure others have realized this, is to char whole trees using nuclear or solar heat. Recover wood gas and useful compounds gassing out and condensing and then simply bury the charcoal tree trunk in the desert. That tree trunk is now carbon that can never come back without being burned. Or turn it into soil improvements for water and nutrient retention. All the charcoal pre-columbian Amazonians produced to enrich their soil is still sitting perfectly as safe and sequestered as the day they tilled it in centuries ago. It will sit there for millenia.

  7. There is a huge benefit from hemp but it requires being grown in the ground. It adds an incredible amount of organic matter to the soil which becomes food for soil micro and macro organisms, improves tilth, helps with water retention and improves aeration. Of course all of that soil must remain undisturbed in order for carbon sequestration to occur as well. Henry may have had a good plan, everyone may need to grow it.

  8. Hemp makes a brilliant building material. Especially insulation. But also you can make papers and textiles with it, high quality carpets, curtains, even wallpaper.

    If you then grow fast growing tree species as well (Paulownia or similar hardwood, which is insect and weather resistant) you can build almost the entire home from sequestered CO². Build it to passivehaus standards, supply water with solar water heaters and energy with PV, and you can have a net negative home with zero compromise.

    Just a side note, to get high on hemp, you would have to smoke so much of it, you would die of asphixiation.

  9. Hands up who thinks this smacks of perpetual energy?

    The plant (pun intended) takes in nutrients and uses hemp to convert it to energy to run the system including photosynthesis, power the pyrolysis and then fthe stonking great laser.

    All fine and dandy while you have nutrient rich waste water as a feed stock, but it will either run out or be a significant bottleneck, not for an individual plant (pun intended) but for this to be a global large scale solution.

    At best, hats off and well done Carbotura, but you aren't going to save the world.

  10. "OMG, CARBON EMISSIONS!"… Yet just "ONE" Volcanic eruption can produce as much carbon emissions into the atmosphere as humanity has produced in the last CENTURY in just a few DAYS?! 🤔

  11. it was actually celebrated for thousands of years, it's usage dating back at least 4000 years. Then prohibited in the 1960's to criminalize south american immigrants and black americans. And maybe also to protect the logging and cotton industry 😉

  12. 🌎🌍🌏🌹Linda sugestão. Mas…..de onde virá a água para manter essa estufa ou fábrica de diamantes, talvez com a crise hídrica no Planeta, a sugestão é que se use água como prioridade para a agricultura ou vidas.🌎🌍🌏🌹

  13. We better start having a few extra Bake Sales. At 44,000 tons sequestered per LARGE facility, you only need to build about 23,000 to get the first billion tons of CO2 out per year. About 33 billion metric tons are emitted globally each year lately, so we only need about 760 THOUSAND of your hemp farms to get down to carbon NEUTRAL, and tens of thousands more to get to carbon NEGATIVE. Even if each one only costs $1,000,000.00 to build (which is probably a GROSS underestimation of land and construction costs) these 800 thousand units will cost 8 TRILLION dollars!

  14. Loving this idea. It could eventually free us from filthy oil and all hazards that come with it. But I disagree on the carbon credits. Carbon credits shouldn't even exist. If you take co2 from the air…perfect…don't emit co2 yourself…even better!! But selling carbon credits simply allows other companies to keep polluting the air and, essentially, poisoning every human and animal.

  15. I just came for a video about how graphene is finally produceable at scale and when added to coatings it is the best available material to mitigate corrosion. Meanwhile concrete is strengthened by at least 30%, asphalt is twice as long lived with far less frequency of pot hole formation, and concrete printed structures can be bigger and with less or no steel rebar needed.

  16. Those furnaces look very power-hungry. The only way this will be carbon-neutral is if it is powered by nuclear. Nuclear power will be the solution, ultimately. And if you take air quality and rising sea levels into account, cause fewer deaths.

  17. The issue we have with carbon right now is that the largest producers, which are India and China, aren't going to stop. In the west, we would not have stopped in our "industrial age boost phase" either. To reduce carbon, we can do what we want, but it is for naught until all nations are on board.

  18. Hemp, to me, is:
    1. KY's biggest crop (for rope-making) until it was made illegal, after which farmers switched to tobacco. That's a hell of a trade-off.
    2. Rope
    3. Hippie clothes

  19. I've been pro-hemp for several decades so I liked the video but I disagree that the carbon dioxide being released by human activity is the existential threat they say it is. We're doing a lot of other things like fracking & deforestation that are a more immediate concern.

  20. This is why we are in the deep mess INVESTED INTERESTS BULL SHIT BILLIONAIRSs 🤡what a mess.


    Toxic invested interest killing all life on Earth 🌍💚🤡🔥☠⛽☠. I was working on the GREENING OF LONDON 1980s I was working on what London could do with River Thames and greening of London nothing has been done! have think? Earth is now the main saving we must stop anthropogenic extinction. End toxic oil cartels control over us and governments 🤡🤡 GLOBAL LEADERSHIP Greta and team! start a munity you all need to take on with global non-profit leadership ALL HUMANS WORKING TOGETHERE🌍💚📢📢😊. End the toxic oil cartels hold!! end global governments debt and hold on politicians. the global con must end! Re build our Earth for all life this will come from us all working together global team creativity art science LOVE…..NO TIME FOR THE GLOBAL war oil CON. YOU?

  21. Also, I'm very curious if anybody has a clue as to why so much money being spent on maybe, someday we can colonise the Moon or Mars when we are so H*ll bent on not saving our own?

  22. I 'd just like to say I'm no expert on climate change but I understand the basics but this one blew me away, I would really like to see at least 1/s of this technology in action and see how it could work in a real-time environment. I am also thinking that if that maybe bio waste water could make the process work any better? Anybody have any thoughts?

  23. Thanks once again for an excellent, accessible description. I work with an environmental non-profit challenging local fossil fuel projects (and now working on pressuring existing fossil fuel plants to convert). The amount of questions popping off from the public is dizzying, so having good, solid intros like yours is a great starting point to having answers. Biomass power plants is a big fight here in Massachusetts as well. Our state administration still incentivizes biomass by qualifying them as "renewable" in the Renewable Portfolio Standard. It's great to see you quote Mary Booth whenever you delve into that subject. She is SUCH a resource and we're lucky to be fighting side by side with her.

  24. If you look a cigarettes, a lot of white smoke is produced. I wonder if those biochar factories would not be able,in case of blocked heat waves with open skies, to release a lot of sun blocking white smoke.
