Java all the way if you need anything graphic

Yes you can combine the two. Infact you can combine NABTEC and WAEC

foresight

Kukah was the only clergy i trust in the whole christendom but his recent acts are giving me a second rethink. Hope he is not among the yam eaters or saboteurs of the nation

What should be the right punishment to this shameless thieves?
Even a firing squad is too lenient for these terrorists

Compensation indeed
CAPITAL THIEVING THIEVES

death by firing squad is the only right punishment

what have you people done on zoo or national management in your 6 years tenure? how did you know the ritualistic functions of the lion's body part if you are not party to such? there is no course in any institution teaching that i schools

wonders shall never end.
come to think of it the North are not crying of witch-hunting unlike such tribe yonder

RIP
the question is what did she die for. i wish she died for a great cause like protest against poor road networks, poor education, corruption in our society or any great cause not protecting criminals or opportunist.
is she the only victim? we need the names of the rest and also the two police victims killed.
what is IPOD/MASSOB doing for the families? i wonder if they have the names of the unfortunate victims.
safety is ones utmost responsibility

a criminal is a criminal. irrespective of religion. did the bible ask him to rape or kill?
we should consider individual crimes as such not carpet profiling. the muslims are always at the receiving end of such general profiling.

Nnamdi Azikiwe was the ceremonial head while Tafawa Balewa was the main man running head of Government

President - ceremonial
Prime Minister - main man.

Ceremonial or not he was the president in the first republic. Anyway what about Aguiyi Ironsi?

The protest symbolizes many years of neglect of the zone by the federal government. Since Nigeria achieved independence in 1960, no Igbo man has occupied the seat of executive president, and it’s not likely that any will do for a long time to come”, says Elder Kalu Kalu, an Enugu-based public affair analyst.

Who is Nnamdi Azikiwe? And what is his position in the first republic?

what should we call these devils?
Terrorists or Criminals?
death by firing squad should be revived in this country

I believe the most corrupt institution in Nigeria is neither the police nor the civil service but the judiciary

Explain?. All European countries are now on 30%:wind and solar. The UK has thousands of offshore wind farms generating power in the sea and sending it onshore. Solar cells are getting cheaper and the government wants people to pay for the panels small small. You can be powered off grid for 24 hours.

Solar /wind Only on paper. the entire europe and west are on nuclear not solar /wind. It is a propaganda

skyfall:
Ngasky,Concentrated solar power (also called concentrating solar power, concentrated solar thermal, and CSP) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area. Electricity is generated when the concentrated light is converted to heat, which drives a heat engine (usually a steam turbine) connected to an electrical power generator or powers a thermochemical reaction (experimental as of 2013).[/color]"

The beauty of CSP is that it doesn't require constant daylight/sunshine. The heat of the sun is stored overnight in special thermal liquids so that the thermal plants run round the clock. And in spite of all, it's cheaper to build than traditional power plants.
cc Gbawe

Sunlight extends to nighttime? We are back to batteries once again (the special thermal liquids) . You admit this is experimental as such they must be extra extra expensive. Think of the amount of energy to turn a turbine and remember the law of thermodynamics the input is always greater than the output. (Perpertual motion machine analogy)
What is the size of the lens or mirrow to generate just 1000w of energy
I am very interested in that liquid that stores heat energy and if possible i would like to know the chemical name of that substance with such great possibility. Thank you

Rossikk:
Prices are falling all the time.
You can store energy for off peak periods. More solar panels are becoming efficient enough

but not fast enough for millions of panels and this is a new technology so there is patent right to contend with
secondly as someone above insinuate we are trying to bypass batteries and problems associated with energy storage even do i know it is impossible but just for the sake of debate

Gbawe:
Solar continues to become more reliable and easier to maintain. Today there are even self-cleaning coating for photovoltaic panels.

With the batteries, my impression is that this is not an issue if running a solar farm with photovoltaic panels directing energy to an inverter which then supply power directly to the grid (see article below). Batteries matter if we are talking of a solar plant where power goes from the solar panel to batteries and then on to the inverter before output to a grid. In any case, my impression is that battery technology has come a long way and that there are now many near zero maintenance batteries available.

Overall, our VP has stressed that renewable energy is part of a 'mix' to alleviate our power challenges going forward and I think it is an option worth looking into since we have the comparative advantage of very good sunshine all year round and the required land to establish solar farms

good analysis. but the problems are:
1. self cleaning of dust equipment is out of the world in case of price. also we know that dust and dirty particles are neutral in charge. if they have specific charge we can use electro or magnetic surfaces to repel them. so in this case we must use something to wipe the surface. so we can have a motor just like wiper to clean the surface. such wipers must consume electricity (energy loss)
2. it can be used to provide electricity without batteries if you are planning to use it for only 6 hours per day why ? because lets take example of Sokoto state it has the highest daytime hours in the country that is why the solar energy research institute of Nigeria is located there. the sunrise time is between 6-7am but the panels only reach their peak values by 11-12 noon and by 4:30pm it will start decreasing until sunset which is around 7 pm. so you have about 6 hours of peak value everyday at best case scenario.
3. solar is an open system as such if the panel reads power output 120w the expected output will never exceed 70w at best case because open system has efficiency of less than 60% unlike closed system which can be as high as 95%
4. as for osinbajo he is a lawyer not engineer so he may not know all these as even Electrical engineer only those who work on these projects understand these salient issues. and the people tabling this idea to him have a lot to benefit if the government agree. if you know a single person among them follow that person to his home you will see he is using a generator not the solar he wants to dump on the government

pikin wen no comot from him papa farm go think say na im big pass. I'm sure you did not read my post and COMPREHEND

i thought i am discussing with educative buddy over there. oga continue.

mikolo80:
can be cleaned with wiper
don't need batteries for concentrated solar thermal. do you have any other use for ½% land in the DESERT

no battery for sure?! BATTERIES ARE A MOST REQUIREMENT IN SOLAR INSTALLATION
where is the desert land in Nigeria ? i think you didnt travel across the country.

Ikengawo:
how about Norway thats also an oil and gas country? Are the excuses valid for them? As we speak buhari appointed a minister of communication that wears gloves to not shake women's hands. With this level of progressive thought in nigeria wtf is osibanjo talking about? Put things in context. Nigeria can barely manage to have roads, but were ready to be a solar super power? Seriously

this is a worldwide problem. even the mighty Russia and Saudi Arabia are not spared
as for politics this thread is for technical feasibility of solar not someone's religious belief. u dont think shaking hand without gloves can give us the solution. if it does UK would never had developed. as the head(queen) is always wearing gloves to shake hands.

Gbawe:
@Ngasky. Article is lengthy so feel free to scan over the parts in bold print.

Gbawe:
@Ngasky.

all the same have they shown or talk about the batteries? they did that intentionally . and assume those panels will last 25 years which i personally doubt based on experience ( I've been with solar energy since 1988) a conventional plant have a lifespan of atleast 50 years.
definitely battery cannot last for more than 5 years and think of even the weekly cleaning of panels (if there is no sandstorm or dusty weather) and other maintenances.
ask anyone with personal experience on these solar /wind energy he will tell you what he goes through in the name of saving

solar /wind can only be used for very light purposes not as a base load power station.
ie powering computers, light bulb, and fans

Ikengawo:
Your intelligence is appreciated but you should also mentions that nigeria drills gas, sells it for peanut prices then buys it back from the west at triple the worth and cant manage to produce electricity from its own gas plants

unfortunately in oil market the owner have limited control of the price. the customers have greater control. added to the cost of transportation and refining thats why we have the above problem

Gbawe:
I agree about the cons which is mainly the relatively huge initial outlay required to produce renewable energy. Long term use will claw back costs and the energy produced is 'clean'. While financing is a challenge, it is by no means an insurmountable impediment.

in the long run have you consider the enormous challenge of maintenances? cleaning millions of panels at least weekly. replacing millions of batteries every 5 years? loss of thousands of hectares of precious lands. huge cost of replacing faulty parts e t c
mr owelle is only out to enrich himself to the detriment of the nation

this is not feasible technically. it is an attempt to deceive the government. the cons against solar or wind power are greater than the pros
