Explain yourself.

you think this is sarcasm? Anyone moving out of Rivers State will appreciate the beauty of good roads. I could not use Delta State cos i know  the roads was constructed by  James Ibori.

Students with their Urine powered generator at Maker Faire Africa in Lagos

Now on the face of it it ticks a lot of boxes – developing nation ingenuity, young kids sticking it to the energy companies and the green credentials (hey – urine’s a renewable resource right?).

But I’m not so convinced.

The claims

The claims is that “1 Liter of urine gives you 6 hours of electricity.”

Wow, 1 Litre of urine and 6 hours of electricity.

The following is on the site explaining it.

The system works like this:

Urine is put into an electrolytic cell, which separates out the hydrogen.
The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.
The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.
This purified hydrogen gas is pushed into the generator.
Along the whole way there are one-way valves for security, but let’s be honest that this is something of an explosive device…

What is in Urine?

Going to that bastion of semi-reliable information (wikipedia) – I find that:

Urine is an aqueous solution of greater than 95% water, with the remaining constituents, in order of decreasing concentration urea 9.3 g/L, chloride 1.87 g/L, sodium 1.17 g/L, potassium 0.750 g/L, creatinine 0.670 g/L and other dissolved ions, inorganic and organic compounds.

Ok, so nearly all water – and 9.3 g/L of urea. Hrmm.. On the face of it and with limited research into the chemical energy in urea – that’s not sounding like something that is likely to power a generator with a 10-40% efficiency (and that’s being very generous with the range).

The apparatus

Let’s take a look at the picture from here.

https://nathan-lee.com/blog/wp-content/uploads/2012/11/IMG_4498_resized.jpg


The setup

Now it looks to me like a very daggy looking battery (the “electrolytic cell”), several water filter holders, a modified gas cylinder, some tubing, clamps and a generator. The bit from the generator to the electrics is pretty non-contentious – have seen similar things – a light to provide some load/indicator that energy is getting through and some powerpoints to plug the stuff in you want power to.

The “electrolytic cell”

Can’t really see what’s inside that or how it is filled up with urine etc – but keep in mind it’s got to be well sealed enough to pressurise the gas cylinder via the water filter thing in between. Also curious about the wires leading from it to the generator. What’s up with that?


Close-up of the battery and generator

https://nathan-lee.com/blog/wp-content/uploads/2012/11/batteryAndGeneratorCloseup.jpg

Have they just hooked up the battery to an inverter perhaps? Surely people will expect the generator to be running while it is powering the lights. Or is it supposed to close the loop on supplying power back to produce hydrogen?

Water purifiers

https://nathan-lee.com/blog/wp-content/uploads/2012/11/Water-Filter.jpg

Next in the chain is the first of the water filters. What’s it for? “The hydrogen goes into a water filter for purification, which then gets pushed into the gas cylinder.”
Ok, let’s go with that. First up it has no filter in it. Next up: it’s not pushing liquid through and a “water filter” only makes sense if you’re pushing water through it – I’m not sure what the point of it is – surely the gas would just bubble straight through to the exit? e.g. the liquid in it is irrelevant like blowing into a glass with a straw not in the water – the air doesn’t magically go down into the water – it just stays at the top. If you filled it to the top you might get a bit of water blown out initially but then it would have cleared a path. If it had a hose down it you’d get a sheeha/bong type result – but how it is currently I don’t see how it does anything. It’s ok, these kids don’t hang out with the drop-out pot-heads enough to know how to fashion a bong out of an Orchy bottle. Even if you tipped it upside down during operation it would proceed to blow out all the water until it was clear and then the gas would flow straight through.

Here’s how they are usually set up to filter water:


Water filter.

So water comes in – is pushed or pulled through the filter – and then flows out. If you don’t have the filter there – the water just flows straight out.. If you tried blowing air through – it’d just flow straight to the exit.

So you could take that out of the system – a sign of many “perpetual motion” and “free energy” machines where they stick a big coil, magnet or a mystery big resistor or something in there.

The gas bottle
There’s some things wrong with the gas bottle too.

https://nathan-lee.com/blog/wp-content/uploads/2012/11/bottleCloseup.jpg


Some suspect bits on here too

No clamp on the “input” – which I’m not sure what that is and how it works. Looks like a repair job, but not sure what that other bit is – looks like a plug or something on the side of it. The corrosion might be because they welded the wrong metal on there? But generally you don’t want too many valves/openings in your tank as it is a point of failure – certainly not a big drain sized opening or whatever that is.

Another water filter

https://nathan-lee.com/blog/wp-content/uploads/2012/11/filterWithCrapOnEnd.jpg

Then there’s the next bit – don’t have any idea why you would have filters on the stuff going out to the atmosphere (I presume that’s what that is).


What is all this on the end?

Huh? Why would you care about filtering whatever comes out that bit – either they’ve hooked up their sham rig incorrectly (e.g. this stuff with the filters should be hooked to the electrolyte cell or to the gas tank or somewhere that makes sense. Double filtering something that is going nowhere – why? Again, those could be removed for the same impact.

And finally – 6 hours of running a generator on a litre of petrol is probably pushing the friendship a bit – 6 hours of running a generator on 95% water content – unless it’s uranium or fairy dust disolved in it is probably a stretch.

Conclusion

While I’d love to believe the story – I just don’t buy it. There’s either something very wrong with their setup or it’s just pointlessly complex for no apparent reason.

I’m labelling this a quack gadget – in line with the perpetual energy machines, magnet only motors.. Urine powered generators are in good company.

But happy to be proved wrong and we can finally harness the grubs who piss in the street and the urinal at the pub could run the lights.

Anyone else got any thoughts?

7lives: Very good, people don't want to use their brains so everyone is either running away to abroad or Lagos. Lagos is now a concrete jungle, its about the survival of the fittest, law of the jungle.
I said it without remorse that by the time the Lagos state government is through dealing with the mad influx into Lagos, most people will sit and work out their survival in their villages and leave Lagos alone. What madness, between 10 to 12 people in 1 room in Lagos, another craze going on is 100 per night in crowded rooms, Babies,children and pregnant women inclusive, bread hawkers living in bakeries, abokis, okada men and area boys sleeping in front of people's stores and abandoned vehicles, what about living in dump sites and under bridges,market places and churches all in a desperate bid to live in Lagos.
People have themselves to blame for whatsoever befall them, people who were left behind in the villages are not stupid by staying behind. They have probably weigh their chances and realized that their chance of survival in Lagos is zero, these are the smart ones, not the ones who came to Lagos to chase shadows.
The Lagos state government will continue to look for ways to make their job easier, it is also the jobs of the citizens of other states to demand for better life from their state governments, FASHOLA IS JUST A GOVERNOR OF LAGOS STATE AND NOT THE PRESIDENT OF NIGERIA.
LET THERE BE MASS INSURRECTIONS IN OTHER STATES OF NIGERIA, ASK QUESTIONS, FIGHT BACK, MAKE DEMANDS,THE GOVERNORS ARE THERE TO SERVE YOU, FORCE THEM TO DO THEIR JOBS, YOU ARE THEIR RESPONSIBILITIES, STOP CHASING SHADOWS, LEAVE FASHOLA ALONE, GOD BLESS NIGERIA.

Mekanze: The beauty of Lagos state is it population let say that federal government can develop other states like Lagos i bate you yorubas will b on their knees begging for food, because most of them only have hope on their rent
.I mean house rent.

Abagworo: Apart from Lagos name which other city in the Southwest that is as advanced as Aba. Then show us pictures to prove. Not roadside but skyline pictures like the ones I posted.

acidtalk: Fashola is presently Nigeria's biggest tribalist.

acidtalk: Oga Fasho don dey kolo small small.

Very soon people go dey use Visa from Anambra before dem go fit enter Obodo Lasgidi.

eldoradoxx: I don't think that most Nigerians get this policy right!!! Fashola's govt has been illegally deporting Nigerians of other states who are caught begging in Lagos. There is nothing wrong with govt banning street begging(even where same govt has failed to provide for her citizens) but there is everything wrong with deporting these beggars to their states!!! The constitution says every citizen has right to live anywhere in Nigeria. Now what guarantees us that with the introduction of resident identity card that non lagos residents like me can be free to come to Lagos to do my business without molestation and as an expression of my constitutional right. Who is a Lagos resident, what entitles a man to be Lagos resident. The man also talks about illegal aliens and foreigners,. Lagos state or any state in Nigeria has absolutely no right to determine the legality or otherwise of a foreigner in Nigeria, that is Federal matter done by Immigrations service, a Nigerian citizen cannot also be an alien or reside illegally in Lagos for whatsoever reason!!!

What are you nervous about no be una say una want capital of Naija to go from Lagos to abuja, when the owner of Lagos want to claim back his rightful property una come they halla. Yeye people with divisive agenda must leave lagos. Rubbish.

IGBO = ISRAELITES?

What are you people smoking? Lemon Grass?

Okay, tell me the similarities!
At least the Israelites, we know!

Or do you mean the Jews that live within "geographical Israel"?

They dont believe in the Bible, they have their own "Torah' that they read!
They did not accept Christ as the son of God ...l wonder who their savior is!
Even Jesus himself condemned the "Jews", they eventiually murdered him, right?

But then, that is those murderous Jews, the only country in the world still practicing APARTHEID...in 2012!

Now, where in the Bible did Jesus mention Igbos?
Where in the lineage of Jesus, did Igbos appear?

Maybe you share the same "murderous tendency" but then, the Israelis are smarter, by a million miles!

*They dont go whining and crying, expecting the Arabs to give their Soldiers "Ice-cream"!
*They dont go about pointing fingers at everybody, they know when to shut-up and choose an ally! Even with Egypt!
*They know when to play dumb like they are "weaker" even when they are stronger.
*Never is "Gra-Gra", part of their game-plan!

[size=16pt]okay, now l see that Yiibo = Israel![/size]
(Rolls on the floor and breaks a plate of Moin-moin!)

You guys have a serious "identity crisis"!
You once called yourself Ethiopians, then you became Germans and now you are Israelis! Holy Josh! What will you be tomorrow? Japanese or Chinese?


Wake-up and stop day dreaming!
Nothing do you but please, just be yourself and stop this "self hate"!

Lastpage!

Abeg, let us discuss more meaningful things, enough of these child's play!

Bolan123: Which bush u jump out from?

aryzgreat: BIAFRA NATIONAL ANTHEM
Land of the Rising Sun


Land of the rising sun, we love and cherish,
Beloved homeland of our brave heroes;
We must defend our lives or we shall perish,
We shall protect our hearts from all our foes;
But if the price is death for all we hold dear,
Then let us die without a shred of fear.

Hail to Biafra, consecrated nation,


Oh fatherland, this be our solemn pledge:
Defending thee shall be a dedication,
Spilling our blood we’ll count a privilege;
The waving standard which emboldens the free
Shall always be our flag of liberty.

We shall emerge triumphant from this ordeal,
And through the crucible unscathed we’ll pass;
When we are poised the wounds of battle to heal,
We shall remember those who died in mass;
Then shall our trumpets peal the glorious song
Of victory we scored o’er might and wrong.

Oh God, protect us from the hidden pitfall,
Guide all our movements lest we go astray;
Give us the strength to heed the humanist call:
‘To give and not to count the cost" each day;
Bless those who rule to serve with resoluteness,
To make this clime a land of righteousness.

Rayhut: Yorubas and hausas,fulanis hate the Igbos,they will we say that igbo are the one pushing drugs,doing robbery,rituals,atrocities of all kind but when Igbos want to leave Nigeria for them, they will start to catch cold, some are trying to recruit thier self into army to fight igbo succesion bid even IBB said publicly this year in the media that at the age of 70 that he is ready to fight the igbos and make sure they did not breakaway.The truth of the matter is that the rest of Nigeria cannot do anything without the igbos.if igbos breakaway with thier enterpreneurship Nigeria will be worst than Somalia,Chad and Niger that is why they can lay down thier life at all cost to make sure that igbos remain in Nigeria,why is it that nobody fight when Ogoni land declair their independence and when Bakasi ppl was giving away.

Ji_sun_pack: These biafrogs are really really confused. Lagos? ? why not aba or nnewi?

I think OPC should make a public statement, cos we won't allow these biafrogs to be causing nuisance in south west.
