Mustiboy:
This technology has — for as long as I remember — been in existence for over a decade. If it were as efficient as projected, more people would be using it by now.

I personally think it’s just a flex of the cool things one can do with waste, not that it solves any real-life problem. How many amps & volts can it even produce per KG worth of waste?

Some instances are those created with public toilets in Asia. Most of them have been repurposed and just used as normal toilets now.

.
You remember how it all started? Compare it to now and you will see that there is hope. In fact, the amps and voltage can be increased with capacitors that are charged in parallel and discharge in series.
.
As for the Asian eg you gave, it might be that they lack maintenance culture or the zeal to continue using it. I don't know for sure. Nothing is impossible oo. It is only God that can limit science.

ModCaller:
Can it produce up to 10kw of power consistently?

.
I don't think so. But scaling up researches are ongoing. Don't forget the waste treatment aspect. Unfortunately, many Nigerians don't know the importance of proper waste treatment.

do one make we see am.. no dey post bunch of theories

Dagger111:
Do make we see am.

Greenscientist:
You don use am?

DeJoeee:
Show us sample of your work

.
Don't worry guys. I have it in mind to try out lots of experiments. I will post about them when the time comes.

drimzsmoke:
They taught us this thing in microbiology that year

.
I like your course oo. Especially its agric applications like growing probiotics for animals. Can you culture S. boulardii with common waste?

You know what I'm talking about now. That show is misleading the youths.

A typical MES setup consists of two chambers, namely anodic chamber and cathodic chamber; separated by a proton exchange membrane (PEM) that allows the protons to migrate from the anodic to the cathodic chamber. At the anode, water molecules split into protons, electrons, and gaseous oxygen. The oxygen escapes the anodic chamber, protons are transferred to the cathodic chamber through the PEM, and the electrons are drawn to the cathode through an external circuit. In the cathodic chamber, the electrons and protons or energy carriers such as such as hydrogen and CO2 are combined by biocatalysts (eg acetogen microbes) to produce primarily volatile fatty acids (VFAs) like formate, acetate, butyrate, etc. An external power supply is needed to achieve this.

The world have gone a long way technologically. But it seems like Africa is left behind mainly due to lack of research fundings.

There are other ways to desalinate salty water such as reverse osmosis, nanofiltration etc. But MDC is preferable because of its lower costs, energy and environmental impacts.

3. Microbial Electrosynthesis: This is where microbes are feed carbon dioxide (CO2) and electricity to produce chemical products like acetic acid, ethanol, butanol, butyric acid, hexanoic acid and hexanol. This can be achieved while treating wastewater. This is important because CO2 is the major cause of global warming. Unfortunately, this technology is still at an infancy stage.

[b]2. Microbial Desalination Cell (MDC): [/b]Here, microbes are used to turn salty water into fresh, drinkable water. According to wikipedia, only 0.3% of the earth's water supply is usable for human consumption, while over 99% is sequestered by oceans, glaciers, brackish waters, and biomass. With MDC, these unusable water can be made fit for human use.

Apart from generating electricity, MFC can be used to remove excess nutrients from wastewater and reduced its biochemical oxygen demand (BOD) before releasing it into rivers and streams. Excess nutrient can cause algae bloom in rivers, streams and oceans. This is a situation where algae, a type of water plant, will grow fast and cover the water surface. Then they will die and decay. As they decay, they use up water oxygen and cause fish and other water creatures to die in masses.

Biochemical Oxygen Demand (BOD) is the amount of oxygen required by microorganism to breakdown organic matters. If you release wastewater into water bodies without first treating them, microorganisms will use more oxygen to breakdown the organic matters. This will kill or stress water creatures.

MFCs have also been used to remove pollutants like antibiotics, metal ions etc from wastewaters.

There are 3 other variants of MFC, namely microbial electrolysis cell (MEC), microbial desalination cell (MDC) and microbial electrosynthesis.

1. Microbial Electrolysis Cell (MEC): In this cell, microorganisms and an external power supply are used to produce hydrogen gas. Part of the electricity comes from microbes and the rest comes from an external power supply like battery. Thus less energy input is required.

Plant microbial fuel cells
This one is similar to soil-based microbial fuel cells. Just that plants are grown in the soil. The plant roots will secrete nutrients that will feed soil microbes. These microbes will release electrons that will produce electricity. As a result of this feeding of microbes, plant MFC will generate more electricity than soil-based MFC.

The anode can be made from graphite, carbon brush (best), carbon cloth, carbon veil, stainless steel mesh etc. The cathode can be made from activated carbon (AC), modified activated carbon, AC mixed with polytetrafluoroethylene (PTFE) and pasted on a stainless steel mesh, carbon black, carbon black modified with aerogel, carbon nanotubes (CNT), carbon nanofibers (CNF) graphene etc. Don't let these names scare you though. Some of them are quite simple to obtain. For example, you can use the lead in pencil as graphite. You can make activated carbon by treating charcoal with chemicals like lemon juice, bleach, potassium hydroxide, calcium chloride, phosphoric acid etc.

What happens in a MFC is that microbes attached to the anode surface will eat organic matters and produce:

1. Carbon dioxide (CO2)
2. hydrogen ions H+ and
3. electrons.

The electrons will flow externally from anode to the cathode as follows: from the microbes to the anode; anode to copper wire; copper wire to the load and load to the cathode. This electron flow generate electricity that powers the load.

Internally, the hydrogen ions will flow to the cathode chamber through the separating membrane where it will combine with electrons and oxygen to form water.

One disadvantage of microbial fuel cell (MFC) is their low power output. A MFC with a 1 square meter anode surface area will produce only about 0.4 miliwatt depending on the type and components used. You need about 1 watt (1000 miliwatt) to light up a high power LED light. So a MFC needed to light up this LED will need to have an anode surface area of about 2500 square meter (Roughly one-third of a football field!). But there is hope due to new scientific advances that have been made after years of research. By using specially made electrodes and more effective configurations, power output have been boosted (up to 2 watts per square meter!). By connecting the output of many MFC in series or parallel, MFCs have been successfully used to power LED lights and even charge mobile phones.

Soil-based microbial fuel cells
In this type of MFC, the anode is buried few centimeters in the soil while the cathode rest on top of the soil (or it is slightly buried), and is exposed to air. The soil must be wet and rich in organic matters like dead leaves, manure etc.

Do you know that any dirty water (waste water) containing micro organisms can be used to generate electricity? The dirty water can be manure slurry, waste water from agro processing, urine, brewery wastewater, kitchen wastewater etc. This can be achieved using a microbial fuel cell (MFC). So how did scientists achieve this feat?

One of the simplest setup consist of a 2 chamber container. The chambers are separated by a membrane which can be a costly material like Nafion or a cheap one like earthenware. Two electrodes are placed in the chambers and connected to a load (such as LED lights, sensors etc) using copper wires. One of the electrodes is called the anode (negative) and the other a cathode (positive). The anode chamber is filled with wastewater and sealed to prevent oxygen from entering while the cathode chamber is open to air.

Any parent that buy phone for your child without proper monitoring, you have destroyed that child. Even if he is 25 years. Porn is just few clicks away.

Chidiebubeoji:
Wow. Thanks for constant replies...
I'm glad to hear that.

.
Wlcm

BigBrother9ja:
You must prefer a 23 years old SLÚT that has lost count of her bodycount then.
23 years old that has done multiple abortions and has slept with various married men.
You're indeed a very "smart" dude

And for your unnecessary second question, common sense should have told you already...
Example is the birth of Jesus...
Why didn't God pick a SLÚT to birth him?
Why is Virginity valued in many cultures?

.
Very good reply. But I hope you dont support BBN.

Brineharry:
is doing fine

.
Thank God.

Farmerakinloye6:
30kg should be More than enough.

.
How far Farmerakinloye6. Is naira redesign affecting price your side?

Chidiebubeoji:
Ok. No probs. I'm switching back to greengo any way.

Thanks.

I have little quantity of chicken manure
Can I mix it with pig manure?

.
Yes.

I've been an introvert all my life. Combined with shyness. Add to the fact that I so much hate dirty jokes and ladies who dress and behave like prostitutes, my own have entered another level. But if it comes to my areas of interest, I tend to overcome shyness and go for it.

Wow. Congrat and keep us updated. Farming no easy.

Brineharry:
if u have way, i advise u get a layflat instead of pvc as it is more flexible and last longer

.
Hw far about ur farm?

Chidiebubeoji:
Thank you sir. So sir, I am planning to use pvc pipe as main line for my drip set up.

If you might have an idea, What kind of iron rod material should I use to punch holes on the pipe ?
So that my drip connectors will fit perfectly on the pipe?

.
I've never used drip b4.

Chidiebubeoji:
Farmtech, Another question sir, how many fruits can one cu999 plant produce?

I've never counted bc of time. But it shud be mpre than 6.

Chidiebubeoji:
The project I just finished was greengo.
They liked it though for it's very greenish colour.
But some buyers were still asking about the usual big cucumber they know (cu999)

Please sir what quantity of pig manure should be ok per plant?

.
I use a bucket with a volume of 12L. I fill it up with pig manure and apply to 5-6 plants.

Chidiebubeoji:
I think cu999 is the most desired variety here in Delta. Majorly For it's size. It's what I'm planting next.

.
I think it is greengo because of long shelf life. Which one did you plant?

Chidiebubeoji:
Wow ! Congrats. Which variety sir?

.
Thanks. CU999

Chidiebubeoji:
....@farmerakinloye
I'm starting to feel like this is my diary.....lol....

Just felt like sharing....

Lukuluku69:
Can you reference a society/family that The God of Israel destroyed because of Polygamy?

I know of Sodom and Gomorrah, so tell us or show us where The God of Israel destroyed anyone/society because of Polygamy?

Mama Kobojunkie, I guess this is your new moniker or the alternate?

.
Eviana CANNOT be Kobojunkie. Checkout their posts and you will see the difference. Arguing with Kobojunkie is always futile. I've done that in the past. Imagine he/she supporting christians who sing dirty songs, crack dirty jokes, watch dirty movies and dress half naked. So Kobojunkie is a 'she'? I thought it was a 'he'. On the other hand, Eviana is more reasonable in her ideologies. Also frank.

Doremii:
The fact still remains that God did not sanction all those guys. You are only talking about the negative side of it. I still consider it far better than homosexuality that God destroyed cities of sodom and gomorrah because of. One of the purposes of our existence is to become populous and polygamy helps in achieving this. The white should legalise polygamy instead of homosexuality!

.
To whom more is given, more is expected from. For Christians, it is one man one wife. We won't be judged the same way as old testament people. We have Christ, they didn't.

Eviana:
I haven't read her writing, but i definitely know who she is/was......her and Helena Petrovna Blavatsky....
Those women were definitely used by the enemy in a very, very wicked way.

.
Satan isn't asleep. But many 'Christians' are.

Eviana:
I have to agree with you about the destruction of the traditional family in the U.S.
There is spiritual warfare occurring on the institution of marriage as defined by the Bible.
It all starts with the family.
Destroy that and you basically have a destroyed nation.

.
Do you know about Alice Bailey 10 point agenda for the destruction of Christianity.?

Hmm. Black lips. Black tongues. Which kind symptoms is that? Autopsy shud be done. So sad.
