Finally! I’ve been searching for a vid like this about a research regarding a combined wastewater treatment and energy generation. Although, I was wondering if this is by any chance the same as a microbial fuel cell(MFC)? Cause that’s really what I’ve been searching about for my research too, I’m a senior high school student btw. Hopefully you’ll come across this sooner! Thanks in advance!

[@aleenaaminkhuwaja8489]

It certainly seems that it a sort of microbial fuel cell

[@tiernanboyd1475]

This is so interesting, thank you for explaining!

[@arhondanielle2315]

It was a great scientific innovation for sure. I'm a Senior High School Student and we are conducting a study related to this. Do you have any papers or sites that can explain further the steps regarding "Algae to Electricity" Process? Something that can elaborate the "Anode" "Cathode" "External Circuit", "Algae (types and content)" and the changes to the "Protons & Electrons" I hope you'll be able to read this. Answering this will surely be a big help. Thank you!

[@syazwansharani8907]

Hi Arhon, wow glad to know youre working on such an interesting project at school. I wish I was able to do the same during my time! Of all the papers that I referred for this study, I found one particular paper called "Biophotovoltaics: oxygenic photosynthetic organisms in the world of bioelectrochemical systems" by McCormick et. Al. to be most useful. It's basically a comprehensive summary of this technology and all the research leading up to it. It should be on google scholar i believe. All the best for your project!

[@arhondanielle2315]

Syazwan Sharani Thank you, Sir! I'll try to look for the paper you mentioned. This is much appreciated. Thank you again!

[@dinosore4782]

This is what humans are missing , when we figure this out , energy will finally become cheap and free

[@JohnnySmith1234]

what prevents the oxygen and hydrogen from immediately recombining in the anode side?

[@clbkhkt-pct5961]

great video. I'm currently working on a project involving this configuration, may I ask the amount of Ferrycianide that you put in the cathode chamber, and how did you attach the algae onto the anode. Thanks alot

[@mysterje]

Greate video thanks, I'm just about to build my own plant power plant using Biophotovoltanic.

[@gayanmax00]

Hi bro. What are you used for cathode and anode. Pls

[@percygaffane1645]

Very much appreciated innovation. Do you think algae technology can produce electricity that is able to sustain a city?

[@syazwansharani8907]

Its hard to say. I've seen one study where the algae is able to power a small digital clock. Who knows once we've optimised everything it will be possible one day. Perhaps it can be integrated with the city's sewer treatment system and hence produce electricy and treat city's waste at the same time

[@nickpelov]

I'm missing important information here. How did you get the 1.25 W/m3? Also it's not important how much is produced. It's important how much you can harvest. The sun produces up to 1000W /m2, but that's not what we actually can harvest. So it would make sense to measure the voltage only under know load, so you can measure the energy. Or maybe charge capacitors. You can measure voltage a lot easier. The earth atmosphere has 100 volts per every meter height. But the voltage itself is useless unless it's maintained under load (which is actual power generation)

[@kemptoby6222]

Hi, sure your video, we are interested, to discuss your project on algae, and also discuss future business.

[@adityavichare28]

Loved it man❤️ very informative..would like to contact for some information on this project👏

[@supriyabharte3234]

very well done

[@josephdvid6]

DO you think you could scale this up by putting 100 of these in a row to power a house?

[@anindasundarmodak7285]

Hey, Can I get a link to your paper? Then I can use it as a citation .

[@sweetmandarin1231]

Do you think there could be any way that this technology could be paired with Hypergiants's Algae bio reactor that extracts co2 from the air to become a triple threat? (CO2 removal, waste water treatment, electricity production)

[@philipm3173]

If it's phosynthetic, that means it uses CO2

[@adrianmok8557]

what is the material used to make your electrodes and how do you separate the two compartments (anodic and cathodic)?

[@DSLRPICS-le7db]

Sir, why did you use K3[Fe(CN)6] here? Also will any waste be produced from the reaction? For how long will the reaction continue and what can we do to make the reaction continue for a longer time? If take your time answering these, that'll be a great help. Thank you!

[@SuhaibAnsari-nr4bg]

electron is going to cathodic chamber. So there must me an electron acceptor in the cathodic chamber to accept it. Here, potassium ferricynide was used for this.

[@azscab]

As an idea to take co2 out of the atmosphere to reverse climate change I was thinking of growing saltwater algae in the desert. I found your site to see if it was possible to produce electricity while growing the algae. Fertilizer is the problem with my idea but using it to treat waste water is a great idea and takes co2 from the air it just needs to be done on such a massive scale to lower the atmospheric co2.

[@syazwansharani8907]

Wow, interesting idea. Can u describe further on how would you grow the saltwater algae in the desert? What would be the water source for the algae? Is it gonne be like a raceway pond kind of setup?

[@azscab]

@@syazwansharani8907 I have watched some documentaries and lectures on carbon capture. The factories require a lot of energy which would compete with other energy uses, household and industrial. Another option is to fertilize the oceans with iron I think to cause an algae bloom. I was thinking how could you do so it wouldn't be competing for resources. Fresh water algae would be competing for fresh water but no one will miss billions of gallons of ocean water. I picked the deserts because then you wouldn't be competing with other plant life for growing space. Fertilizer is a problem but if you use cudzo it would fix it's own nitrogen because it's a legume and fast growing so it would be capturing carbon while you fixed nitrogen. I don't know any details I was just trying to think of a way to capture atmospheric carbon without competing for resources and make its biproducts useful like make electricity or livestock feed, or biodegradable packaging, or compost it into soil.

[@azscab]

It should be near the ocean since you would have to pump billions of gallons of water to the growing area. Glad you like the idea. I think it is very important that humans find a way to remove co2 from the atmosphere since we have gotten so good at putting into the atmosphere. I would prefer that to any other geoengineering method like spraying so2 into the stratosphere or even the upper troposphere.

[@azscab]

Hemp would make a good carbon capture crop. I think the important thing is to find waste land that is having a difficult time growing anything.

[@azscab]

I would pretty much drop everything if I thought I could help save the world by reversing climate change.

[@timomoto4182]

Hey. cool project. what kind of algae did you use?

[@itamaritamar9009]

Is the electricity used for the system to work (such as a light source ) higher then the amount of electricity produced?

[@Ewr42]

obviously. algae need energy to survive and reproduce. I've heard it's only 0.25% efficiency

[@emilypotter2054]

Question, what was the Potassium ferricyanide used for in this set-up?

[@SuhaibAnsari-nr4bg]

electron acceptor

[@manuelbautistagarcia8199]

amazing work, i want to do something like this using marine microalgae, some advice?

[@syazwansharani8907]

Hello, sorry I just noticed your comment. My advice would be to use different types of microalgae species and compare their ability to produce current. Usually the one that is able to produce a stable formation of biofilm on the anode would be the one that produces the highest electricity. Once you've selected the best species, you can move on testing other materials like type of electrodes used, the cathodic solution, and the substance you use to feed the algae

[@bedabyassingha7957]

What type of electrode is used?

[@soberssarker7985]

Can it be used in open water like in pond?

[@jacobsimpson347]

An-ode. Cat----- cath-ode

[@dhupee]

do you have a paper of your research???

[@syazwansharani8907]

I've submitted it for publication, but still waiting for the result. Will update you once it's published!

[@dhupee]

@@syazwansharani8907 if you have the paper i'll use it as citation for applications, plus if you want try to look at salt water battery, if you can combine it.... i know how to applied that

[@raymo7927]

May I read your final paper please ?

[@aatrel8346]

hi man i wanna talk to you
