Night Time Solar Power Station.....Mr....Gillani Learn From This....

ANDALUSIA: A unique thermosolar power station in southern Spain can shrug off cloudy days: energy stored when the sun shines lets it produce electricity even during the night. The Gemasolar station, up and running since last May, stands out in the plains of Andalusia. From the road between Seville and Cordoba, one can see its central tower lit up like a beacon by 2,600 solar mirrors, each 120 square metres (1,290 square feet), that surround it in an immense 195-hectare (480-acre) circle. "It is the first station in the world that works 24 hours a day, a solar power station that works day and night!" said Santago Arias, technical director of Torresol Energy, which runs the station. The mechanism is "very easy to explain," he said: the panels reflect the suns rays on to the tower, transmitting energy at an intensity 1,000 times higher than that of the sun's rays reaching the earth. Energy is stored in a vat filled with molten salts at a temperature of more than 500 degrees C (930 F). Those salts are used to produce steam to turn the turbines and produce electricity. It is the station's capacity to store energy that makes Gemasolar so different because it allows the plant to transmit power during the night, relying on energy it has accumulated during the day. "I use that energy as I see fit, and not as the sun dictates," Arias explained. As a result, the plant produces 60 percent more energy than a station without storage capacity because it can work 6,400 hours a year compared to 1,200-2,000 hours for other solar power stations, he said. "The amount of energy we produce a year is equal to the consumption of 30,000 Spanish households," Arias said, an annual saving of 30,000 tonnes of CO2. Helped by generous state aid, renewable energies have enjoyed a boom in Spain, the world number two in solar energy and the biggest wind power producer in Europe, ahead of Germany. For the Gemasolar solar product, foreign investors helped too: Torresol Energy is a joint venture between the Spanish engineering group Sener, which holds 60 percent, and Abu Dhabi-financedrenewable energy firm Masdar. "This type of station is expensive, not because of the raw material we use, which is free solar energy, but because of the enormous investment these plants require," Arias said. The investment cost exceeds 200 million euros ($260 million). But "the day when the business has repaid that money to the banks (in 18 years, he estimates), this station will become a 1,000-euro note printing machine!," he said, recalling that oil prices have soared from $28 a barrel in 2003 to nearly $130. For now, the economic crisis has nevertheless cast a shadow over this kind of project: Spain is battling to slash its deficit as it slides into recession and has suspended aid to new renewable energy projects. Andalusia, hard hit by the economic crisis with the country's highest unemployment rate at 31.23 percent, holds regional elections on March 25. "We have three projects ready but stalled" because of the aid suspension, Arias said, admitting that in a difficult global economy the group has not managed to sell the Gemasolar techology abroad despite huge interest outside Spain.

I think you two didnt get the point I have raised in my previous comment. Assuming the average annual tax payment rate in Pakistan to be Rs.800/- per head, there might still be millions of Pakistanis paying thousands of rupees tax each year but thats not the point. If we assume 10 family members living in each house, based on the average tax payment rate of Rs.800/- per head per year we cannot expect collection of more than EUR 2 million tax revenue in total from 30,000 households in one year whereas to make this project operational we need 100 times more than that. Even if the government collects tax of millions of euros worth from the citizens each year, would it be just and fair to invest the tax collected from significant population (millions) of Pakistanis on such a power project for the benefit rather luxury of insignificant population of 30,000 households?  Maybe we could find some place in Pakistan where 30,000 households are not only financially sound enough but also willing to invest EUR 6667 each on such a thermosolar project or they would have paid EUR 6667 tax (each) which could be utilized on this thermosolar project for their fair benefit but honestly, I dont know any such place in Pakistan. By the way, do you have any idea, how much of our paid tax actually goes to the government treasury?

yeah Abdul Rehman Ansari well said even on mobile card ka hi hisab lga lian to us py daily itna tax collect hota hai .........aisy hi to in k itny shahana andaaaz hain........ wo sara ka sara hmary paiso sy hota hai..... apny aish km nai hoty and zroort ki chezain udhari mangty hain ..... shame on them

Can our government afford to invest EUR 200 million to light up just 30,000 houses? The answer is definitely "negative". I think in Pakistan's scenario, this thermosolar project covers just one small district.
Suppose we have 30,000 households who are ready to invest EUR 6667 (Rs.802,667/- approximately) each, for enjoying 24-hour electric power package with nominal monthly maintenance charges. This much investment is equivalent to advance payment of usual electricity bills (@Rs.2500/- per month for each house) for 26 or 27 years. Considering possible inflation and increase in power use in future, we may restrict the number of years from 27 to 20. So who wants to invest 20 years electricity bill payment to minimize his/her monthly electricity bill to monthly maintenance charges? I am not a PPPP supporter and I hope no one would blame me for being one.

ohhh dill jlta hai daikh daikh k kaisy kaisy log electricity produce kr rhy hain wind power, solar energy, coal, oil, water even garbage jo dhairo dhair pra hai roads k aroud glio mai railwy lines py........... and we people jo hmara pani rok k bijli bnata  hai hm us ki minty kr k khreedny ka soch rhy hain.............
