Fascinating, thanks so much for sharing. I wonder if the use of chlorine in water, as well as the plethora of other antibacterial products on the market today would pose a problem for this type of technology? I assume for this to be viable there would also have to be a cultural shift away from chemicals that would kill bacteria. After all waste water is where most of it ends up.
This is a very good observation. I think (wether the disposal of antibacterial products poses a problem or not) the main focus should be to push government funding and exposure to this technology, rather than a cultural shift away from chemicals that kill bacteria.
Generally speaking, chlorine gas a limited disinfection capacity, and forms disinfection biproducts as it is used up. I imagine there won't be enough residual chlorine in wastewater to be concerned about.
Thabks for the video and the presentation, but with your permission I have a little question. Is it there any problem if the anode and cathode have different dimensions, would it affect the electrons absortion?
You might want to google up Nernst laws. Aerobic and anaerobic bacteria inhabit opposite sides of an electrolytic barrier - and produce a potential difference. Instead of producing methane the system produces CO2 and electricity. This makes a solid state system possible with the only moving part being the poo moving through the system.
Earl, You need to study up on stuff yourself so you get the basics. Information is out there. The internet is awesome! Here's a good place to start. Nothing beats practical experience. ruclips.net/video/yDarDR4vi1A/видео.html Here are some good references with engineering data - once you understand their meaning. www.researchgate.net/publication/315066828_Microbial_Fuel_Cells_Types_and_Applications web.mit.edu/pweigele/www/SoBEI/Info_files/Logan%202006%20Environ%20Sci%20Technol.pdf Here's Nernst equation - once you understand that you can design batteries fuel cells - anything you like that's electrochemically powered. en.wikipedia.org/wiki/Nernst_equation ocw.mit.edu/courses/chemical-engineering/10-626-electrochemical-energy-systems-spring-2014/lecture-notes/MIT10_626S14_S11lec08.pdf ruclips.net/video/iev2WlpKoGc/видео.html Good luck.
Real Mechanics I created a fuel cell for a science project. My results showed that the mass didn't affect the results. Instead, it was the amount of bacteria in the sample.
Were you even listening to the video? The MFC's can't power a lot of electicity. You'd need a very big MFC to produce that much electricity to power your home.
A microbial fuel cell attached to your toilet and disposal for food waste can power a hot plate and cellphone and maybe a jug. Power is limited by the amount of waste you produce. The fuel cell if well designed can also provide fertiliser for your garden (and your garden provides more organic waste processed by the system) along with fresh sterile water to water your garden. Things get interesting if you keep animals. Because they produce far more poo than you do. This is Lindeman's law in action! ruclips.net/video/jV9CCxdkOng/видео.html 10,000 lbs plants --> 1,000 lbs animals --> 100 lbs people \__> 1,000,000 lbs waste \__> 100,000 lbs \__> 10,000 lbs Rainwater is also processed from the solar panel run off into your garden. Where the microbial fuel cell shines is in farm applications where there is LOTS of poo concentrated in one spot. ruclips.net/video/W5vV_K4533A/видео.html Here microbial fuel cells replace the biogas powered diesel generator. A huge savings in maintenance and costs. My company is building a compact skid mounted high rate plug flow reactor that uses thermophilic bacteria in a microbial fuel cell arrangement to create a solid state electrical source for the farm. The only moving part is the poo and the electricity. Everything in a sealed 40 foot container that handles 500 cows and dairy waste - and food waste from restaurants in controlled amounts. The fuel cell works with solar panels and a stationary battery pack to provide megawatt scale power for the farm - to run the milking machines and an electric tractor and the machine itself. There is still a residual backup generator that runs on both biogas and diesel because there is still methane produced. This is only 60 kW. Waste is shredded and steam sterilised like beef stew in a factory before canning - the mix introduced at one end of a long coiled tube where select thermophilic bacteria mix is introduced. The tube is set up like a battery in cross section. It has aerobic bacteria on the inside, of an electrolytic barrier and aerobic bacteria on the outside. The poo is turned by a stationary mixer arrangement in the tube and CO2 is the major gas produced, methane still a minor component though. Gases distilled with an advanced solid state cryocooler which purifies them. LNG and Liquid CO2. Hydrogen sulphide is reduced to sulphur and hydrogen. Hydrogen and nitrogen are recycled through the system. Sterile high protein digestate is dewatered continuously and sterile bedding removed continuously. Wastewater is finished with a photobioreactor after being ion balanced electrolytically through a permeable membrane. This produces a high quality sulphur rich fertiliser and waste water that is ideally suited for algae growth. The waste water is sterilised and algae introduced - and it flows through a photobioreactor. When mature the algae stream is dewatered producing a high protein feed supplement. A coil of transparent tubing 8 inches in diameter wrapped around a reflective film forms an 8 foot diameter cylinder that is 52 feet long - and forms the photobioreactor. Inside the cylinder is another coil of tubing 12 inches in diameter, that forms the plug flow reactor. Inside that is the framework hardware and controllers. It is transported to the site and erected on a portable stand - and started. Waste flows to the top and drops down along the coil. The finished waste is separated at ground level and waste finished algae water pumped to the top to enter the glass tubing and the algae separated again at ground level. A home sized system would be far smaller. A cow produces 55 pounds of waste a day. Scaling down the 500 cow system - to 6 adult males produces less than 5 pound of waste per day. Sizing a poo processor for a single adult male would be 1 ft by 5 ft and require the development of some very low cost robust and tiny hardware to make it work on that scale. Adding waste from a garden changes things. Adding waste from animal raising and slaughter - changes things again. These are not cheap, and the challenge is to assemble a supply chain that does for this technology what Henry Ford did for the motorcar. In the meantime, I'm building habitats for Martians! lol.
This is awesome. I'm doing a project like this myself but with different organic matter.
Thank you so much for sharing such a fascinating video!

They have these small enough to actually print on paper!
So it's light, compact, and biodegradable!
Do you have a citation? This sounds very interesting
i would love some context on this too
Thabks for the video and the presentation, but with your permission I have a little question. Is it there any problem if the anode and cathode have different dimensions, would it affect the electrons absortion?
Is there a way to generate more electricity using Microbial Fuel Cells?
Sir, what theories and principles are used in MFC?

how does the effect of catholyte and anolyte volumes affect the power output?

MythicalShade hey can u give me ur contact number or anything with which I can contact u!! I have a seminar on this !! I want to learn more!!
Kaushik Mungalpara hey there. I have a seminar on this topic too. If you are done with yours, can you help me learn about it?
hi
how can i make abig microbial fuel cell to power my home
thanks
Were you even listening to the video? The MFC's can't power a lot of electicity. You'd need a very big MFC to produce that much electricity to power your home.
And more organic waste than a single household is expected to create.

plants
@@kiana4360 Yes, however, bringing more of the supply chain that support each person into the waste stream, you can get a surprising amount of power.
How do you do this with a plant that treats 80 million GPD of Wastewater?
Dagerous concept
A battery does not work with out the alkaline the bacteria part needs to have magnesium and salt
can you elaborate?
Have a great day in this channel GOD bless always stay conn.soon thank u
Pardon my ignorance, but if they surrender their electrons and lose energy/oxygen, how will it continue to survive?
Ok, re-watched and found out that the microbes grow on the electrode.
The don't produce methane.
Does the anode needs to be air tight?
Yes
super capasitor is much more promising for future energy storage
Supercapacitors can certainly store energy but this video was about energy generation.
The lógic is like ... incomplete or maybe wrong on how it Works...
Use this sucker in a RV
This video is missing the big picture....the proton exchange membre!!! Without this membrane this will not work.
