    Wow that’s a salute 🫡 for the science of modern day Thanks to all scientists for helping mankind grow

    Very interesting and promising.
    Perhaps a detail, when gas bubbles form above the photo-catalyst layer, would that not be both hydrogen and oxygen? If so, how would they be separated? If not, where does the oxygen go?

    Reversal: when artificial photosynthesis pulls so much carbon from the atmosphere we have to pull from the ground to balance it out again 🤔 /s

    What happens to cyanobacteria after it dies? Is controlled shalow pools that will bloom cyanobacteria can help fight carbon levels? Can we sceem the water of the dead bacteria and make ethanol or other camicals? And what is the value of the harmful toxic camical it produces? Can we use it in indestry?

    I really very very interested in this new field Even though I dn't like biology

    Photosynthesis is NOT efficient in nature. It only has an efficiency of about 1-3%. Turning sunlight into hydrogen and oxygen is fairly simple. All you need are 2 electrodes and a solar panel. This chemical reaction is very easy and is often done as a demonstration in schools. Using electrolysis, water can be split with an efficiency of 70% and most solar panels are about 20% efficient, but some are as efficient as 39%. This would give us an efficiency of 14% - 27%. however, If this photocatalytic water splitting exceeds this efficiency, it will be impressive, however. the question of weather it will be easier to mimic photosynthesis on a macro or micro (or mix of both) scale is still a question. Not really any impressive information was shown, but you have to keep in mind this is still a rather new field.

    If only "Political Science" wasn't 5000 years behind Material Science ...

      How so? Poltical psychology has a good idea With what happens. It’s the media and parties that try to make a profit off of it that screw everything up.

    lets take all the co2 we put in the atmosphere!🙌 and turn it into plastic :S

  • @thegamechanger7157

    Solve that now
    The co2 is the problem.

    Not clear how he is going to achieve all that, just explains photosynthesis natural vs artificial

    very interesting but nothing is clear🤔
