Na those Chinese Chengdu plane again ?

Kobojunkie: You are not making any sense. When you are told A makes up 40% of something and B makes up only 19%, what do you think that means? Please consult the meaning of GDP and GNI before you continue.

It surely won't make sense to u that's y u maintained dat side of argument.

Argh!...@OP, Dede1 and Kobo

What's d difference between GDP and GNI ?

Alimosho is 40% of Lagos population while V.I & Lekki is 2% of Lagos population, so which is d higher revenue area?

*hypothetical percentages.

jmaine: The OP deserves severe lashes of barbed koboko strictly landing on his ears for not listening to free education . . .

Which kin pikin pesin born so

U winked o, Bros.

It's nothing extra-ordinary to be illiterate in matters of economic and finance, afterall its only matter of concern and interest. But its grossly stuupid to join a bandwagon in response to a faulty argument on such matter you know little about.

@OP, u need to be tied and left at mercy of school of almanjiri boys to use ur face for slapping-practice for ur interpretation of obvious statistics.

@Ballabriggs, thanks for taking time to school those economic illiterates.

Nothing breaking about bomb blast news in northern Nigeria anymore bro.

@Beaf,

You r a pathethic liar!

U cited half info just to favour your unethical side of ur argument as usual. Shifting sources to suit ur momentary satisfaction. Today u r citing wiki, tomorrow u will criticize another person citing wiki against u. If its not wiki, its Sahara reporters. Such a double faced worm.

I giv it to u dat u hav ideas about sciences, but sounding like an authority and insulting other non science oriented people is kind of foolishness u find among chalatans like u. Those who truly know take time to educate and don't dabbled about in unethical political sentiments. But it will b too much for me to think so highly of u as u r obviously alien to such character regime. Only a literate political jobberman who is directed by vain pangs of his belly and twitches between ur crotch is what u r...don't worry we know u so well.

Now to where u fouled, those coolant u cited r called primary coolants. In some plant processes u can have up to secondary and tertiary coolants. In nuclear plants, d primary coolant Is molten sodium or any of d above coolant u cited. "heavy water" is d secondary coolant used to cool d primary. It's basically water but due to its function has been exposed to heavy radiation from d molten sodium cooling d fuel rods. Then d tertiary coolant which is water is used to cool d heavy water, all these In closed heat Exchange system. Finally Is d open cooling using cooling towers (those massive concrete towers with vase-like look that r common in nuclear plant pix) which draws water from large water body to run its cycle.

Now u r the red-eyed and frothing mouthed shameless liar that needs to get himself slapped. And don't u dare go cite wiki for me on such subjects again or from any site where an oyibo has managed to type something online because u r not fit or qualified to assess my technical competence on such Issues. Neither r u in class of my peers dt can review my opinions on such. Not everybody is a political chalatan, u hear?

Ur Stupidity can sometimes be annoyingly unavoidable

@billyonare

Yea, so quick to discard sound explanations that shows ur ignominy. My friend, if u dont understand that d culture of d people must b blended with democracy, then u must b living in lala land. At this point I excuse you, u can go on preaching your martian type of democracy.

@Billyonare,

Your line of argument so far shows that your r alien to the realities on ground at d grassroots or just intentionally acting dumb.

For Bini in particular, d Oba is very very much more influential than the governor over the people. Or lets say it this way, ...if theres a difference of opinion between d Oba and d governor, te people will gravitate with the Oba. It's their tradition to hold d Oba in highest esteem. They see him as their natural and traditional head while d governor is a political creation. Irrespective of level of education or western acculturation, they never lose this. If you want to confirm, look for any Bini man around you and taunt d Oba to his face.

You talked about using political power over d Oba, obviously you don't know jack about Bini traditional institution. The British tried it and after many years of apparent success, they never could go beyond there and after, everything reverted to status quo ante. Do you know who's Navy Captain Onyearugbulem? Find out about him and know y no political office holder tries sh.it with d Bini Oba.

Now on his endorsement, only a novice to d intricacies of relationship between Binis and d Oba will not understand. PDP failed woefully for many years there when a son of Bini was governor. Oshiomhole isn't a Bini and he has performed credibly. Gen Charles Airhavbiere is a Bini palace son, his father was a Bini chief, and d Oba knew him personally. They came to play son-of-d-soil card with d king and Dats y d king gave d analogy of a stranger child painting an old man's house. Can u now see dt the king has acted honourably without fear or favour?

Lastly, if you only cared to find out, Edos have for d first time felt govt presence, so even without d Oba saying it, the support Is strong. He only echoed d voice of d people.

Mind u,I was In Edo last month and I felt d people pulse on d matter, so I just dished u d reality. Don't be suprised that if PDP dare rig d election, violence will bteak out spontaneously. But even d PDP won't dare that because its next to impossible.

Charles Airhabiere MAY be a good man in his own right, its just dat right now Edo people don't need another governor.

Deje sh' nwa nnam'. Abum' nwa Affa na Udi.

erniok: The Three Gorges Dam in China, Itaipu Dam in Brazil, and Guri Dam in Venezuela give more than 10GW. these are hydroelectricity plants. what is wrong with upgrading our hydro plants. ohh...i get it, we like exotic things that we cant manage and maintain properly and will kill us off eventually.

All those in support of this plan, i wish i can recommend to FG to site the plans in your communities; very, very close to your family houses.

Lolzz...

No waterbody in Nigeria has flow capacities of d mighty rivers on which those dams r sited. Remember those r some of the longest and largest rivers- Yangtse for Three Gorges Dam and Amazon for Itaipu and Guri. No Nigerian river is near them in flow.

The biggest is Africa is d planned Grand Inga Dam in Congo DR with rejection to sell electricity up to Nigeria.

Again, I condemn ds move not because I don't wish Nigeria to advance but because its very very avoidable if power generation is d sole purpose.

A dumb head earlier asked what would Nigeria resort to after we run out of gas. Many half informed people shouting here don't even know dt Nigeria Is more of a gas producing nation than oil producing. As at 2010, oil reserve was 40 years while gas was 120 years. Even as at now, we flare off more gas than we use. And from what we use to power turbines, our transmission system can't support full generation of d power plants steadily without collapsing due to undercapacity and other inefficiencies.

Out of d turbine houses in Kainji, not all units r installed. Some were left uninstalled at commissioning for future expansion and some of the commissioned one packed up years back wtout replacements. Same for Shiroro and Jebba. Dadinkowa for example has d turbines delivered to site where It rusted away for many years without installation. Only read in d news not too long ago dt another turbines hav been procured for Installation there. Similar stories trail most of dams built for agriculture and power pourposes, yet we only know of kainji, shiroro and jebba. Many more dams were in plan and up till few years ago, the govt hasn't done feasibility studies for most of d rivers in d southern Nigeria.

For gas plants, it currently provides over 70% of current national capacity. But wt dt, egbin has uninstalled units, same for sapele and port Harcourt. Most of those plants were built wt future expansion capacities wc have not been activated.

All those said, anyone wt good understanding of Nigeria power problem knows dt the biggest immediate challenge is getting enough gas to d power plants. The gas r there in Niger delta but d handling infrastructural capacity is abysmally low. It's y most of d power plants can't even run up to their present capacity. Currently, Nigeria has installed capacity of about 10GW but generation is about 3.5GW while consumption is somewhat below 10GW.

Don't even mention evacuation and distribution.

Now you see that its ignorance to think that nuclear plant is d immediate need of Nigeria's power crises. Nigeria can conveniently advance without it for another 50-80yrs without qualms. So nothing is pressing about It.

Did I mention coal? What about off shore wind? Do u realize Nigeria has one of largest lagoon formations? ...think tidal.

One ignorant govt apologists mentioned In one thread earlier that d present govt has COMPLETED Mambilla power project....WHAAAAAAT D FREAKIN HELL!!!...JEEEEZZZZ!!! Was nematode has come up again on this thread doing what he's paid for-telling lies! Mambilla that hasn't even been started? Does he think its aboki mai taba kiosk he can build in a week we r talking here? Mambilla is to be d flagship of dams in Nigeria with abt 3GW capacity. That's a monster! ...and here's a joker talking from all cardinal points of his mouth...just like his cohorts from pit of hell.

My point is nuclear plant is not needed by Nigeria for now, period!

Lol. To think dat Onyeama was connected to me by some 3 generations.

@Whitehorse,

Igh bu onye akuku ebe na enugu ?

legendprac: Oga, don't be decieved... Okija was biased wit those pics. As @ may 5th, Onitsha-enugu road was still a mess n i doubt if it has improved(it should be worse now considering d rainy season)...
The road being dualized by setraco @ port harcourt airport road is also messed up,especially wen u start approaching the airport from elele..... @ least, i pass dia almost every now n den. And did this monday 25th june... Only a few parts(after omagwa to elele) are ok. D only one he got right(unbiased) is d owerri-onitsha road.mehn, i love speeding on dat road... But,i don't fink u can credit dat road to obasanjo's administration. It was started before or during his administration but was just completed last year.
And don't say Rochas isn't working. I lived in owerri for 5years, 4 of which were during ohakim's time, and i can say dat rochas has already done wot ohakim couldn't/ wouldn't have done in 4/8years.(And am not even frm imo. Am from anambra)
As for anambra state, that would be for another day,cuz Peter Obi is a failure. All u need is visit anambra after going to oda states to see how bad it is...
All in all, i fink okija was biased wit d pics he uploaded.he was just selective.
But, u try sha....

My friend, u were unfair to Mmuo Okija. Check his last post and see what he already said about Enugu-O'sha xpress way. And on d PH airport road u mentioned, u said it with ur mouth (abi na hand) that its "under construction", so why r u surlprised Its bad? U need to apologize to him bro because u accused him wrongly.

This is foolish priority.

Gas plants, we can't maintain.

Gas feedstocks, we can't even harvest enough to use.

Coal mines r abandoned.

Dams r under utilized and mismanaged.

Refineries r badly maintained.

Pipelines r poorly secured and r numorously leaking

Now we want nuclear plants...

Only babies talk and think like that...oh sorry!...politicians too. If u believe in dat let me hear u say SANTA CLAUS! Yea, Santa is coming to town soon wt brand new nuclear plant to b sited in Nguru desert of Yobe, oh sorry, ...forgot Bayelsa is d new destination choice....but never mind, Santa won't make mistake wt dt.

Only a gullible soul will miss d mischief behind d whole ruse to deflect attention away from obvious failure to deliver on electricity. Do we think the other world leaders think irrationally as ours as to allow/approve a nuclear plant b sited here? Abi we think say na like aboki mai taba shop we dey talk about? It's good to dream and walk in path of ones dreams, but its gross folly not to b able to separate realities from mere fantasies.

It's not dt we dot have d economic credit potential to fund one nor suitable space and people to man it, but we don't have the character as a community to handle complex and sophisticated systems. Worse Is that everyone knows this except we ourselves.

On issue if u should use slip ring motor or not, only DC motors/generators use slip rings.

And on using speed improvement/reduction drive train, I want u to remember dt if u increase speed, u will lose torque; and if u reduce speed, u gain torque. Consider also the attendant losses to friction, slip and elasticity (since I saw in ur drawing a belt and pulley arrangement). For bigger power transmission, those r minor losses, but for a smaller arrangement like what u r planning, it becomes significant and reflects on ur final output.

Wow...wow...wow...

Bro, I guess u hav ur cart before the horse. U normally do all those calculations before u go on to select ur materials and determine d blade dimensions. If you can't even be sure of the wind speed and quality on site u want to use it, it appears you have been guess working wc is not good when working with wind because Its d most treacherous among all the renewable energy sources. It's highly site specific, so a turbine performance in Bauchi may not b same in Abeokuta or Dutse. In fact, d first data set u need before proceeding on design are your average windspeed, humidity and temperature and surface roughness class. The first 3 u can get ESTIMATE values for your locality from NIMET or ur climatology section of Geography department if such exists. Based on d data u get ur wind quantity and quality which is what helps u to derive ur availability and cut-in speed and cut-out speed ( these after u have done ur material selection against d energy available in d wind over ur availability period). By now you can calculate ur blade tip ratio and select ur angle of attack. At ds stage, d surface area of d blade can be calculated easily and from there u can select ur length of blade. At ds point u would also have known d wind force expected against ur blades and height u can harvest best wind quality and quantity.

U were mentioning "6", I guess that's ur tip speed ration. With that I expect a not-so-broad blade but slightly long designed to run fast under low wind. That u have chose 3 blades shows u want slightly more torque at speed expense. Good selection, I say.

Back to my earlier analysis, its at point of design of d prime mover (turbine) dt u were supposed to have selected and matched it with load torque requirements. Again, the calculations would help u to determine the RPM of the designed turbine. All these parameters u can alter to suite the characteristics of d generator or final load. It's at end of these that u go on and start construction based on ur earlier design.

Now, I can only hope along with you that ur gamble works. Wind is unlike any other energy source because of its treacherously unpredictability.

Your major concern for now I guess is on generator selection. Well AC motors r more compact than their DC equivalents, what dt means to u is that it will require lesser torque. U r faced wt compromise of dt with having extra circuitry for amplification and rectification on downstream side versus higher torque whc will demand higher machine (turbine) size.

Hello Sadiq,

I just saw ur post after a friend (who posted earlier on pg 1) told me abt it. Well done, keep it up.

I did works on wind turbine in my undergraduate project and I have followed the technology passionately for over 6 years. I'm quick to notice that u haven't provided some basics before you selves Into construction.

1. What's d average windspeed of d area/site u plan mounting it?

2. What's d surface roughness class?

3. What's d cut-in speed and cut-out speed of d turbine?

4. Have you done your material strength analysis for d blades?

5. What's d blade tip speed ratio?

These r some of d basic info I think you will need even before you go ahead to construct. But ASSUMING u hav done these, then I understand the mix up between electric motor and generator. Usually, AC generators are more used. DC motors have limited use. That does not mean that it won't work though. An experienced electrician can explain better.

I can see that its a roof type u plan to construct, although I don't know what height u have selected to mount it and type of buildings and vegetation around u. I will also ask dt u consider needle bearings for d yaw assembly against roller balls bearing because of losses since d load is not much.

I may not b able to say much more than ds for now based on d scanty info I hav from ur posts so far.

For d power amplification, go to oshodi under bridge where Igbo guys sell electronics parts and components, usually there r electronics technicians there who can virtually help u construct any circuitry as long as u can explain urself clearly.

Wish u well.

all4naija: Lol... Nigerians pay tax! It is one of the worst country in taxes revenue collection. That is not a good point at all to go with in your comment.

It surely doesn't occur to you that some people have honorable means of livelihood and also pay taxes. I will repeat wht @texaspette just said to u, when u grow up and get a decent job and start earning honest money and also pay your taxes, you will know to demand good governance and learn to separate foolishness from wisdom.

No wonder u have sat up all night to preach stupidity.

Also someone who knew him in UNIPORT during his Ph.d days and was told he failed his thesis defence thrice and Alams had to call d VC to save his deputy from d embarrassment before he was finally passed.

@ edicolove: thanks for d maturity.

Football joor!

Hahahahahahaha...nothing wey pesin no go read for hia. Abegiii make una talk sontin ess joor

Kobo, why u dey laff nah?


Maybe u r thinking what I'm thinking

@edicolove,

Thanks for giving us all another view on same matter. Personally, I welcome it and can't agree more with your half-fill-half-empty analogy. Afterall its only opinion and diversity of it shows we r thinking.

I won't debate ur opinion with u, ...no I won't. You hav a right to it, so I will respect that.

Yet, I will make aversion to your last sentence where you were unwise to label me a "hater" and "BH supporter", its very very unwise to say that to people who see issues differently from you and more foooolish to label them what u can't substantiate.

Please follow the language of earlier posters and learn some things about being civil, cultured and cultivated.

Peace be unto you.

Ok, just Google it and u will see more than enough news on him.

This is heart breaking.

But in case any of d soldiers is vowing ds, I implore you not to do anything rash, remember d case of ur colleagues in Egypt. A word is enough for d wise.
