Solar Water Filter – Innovation In Evolution

As they say, without possibilities, there is no creativity. So one thing is for sure, there are endless possibilities but only if we can dig them out. Reducing complexity is simplicity, and simplicity is creativity. Creativity has no boundaries and relies mostly on common sense which is rarely common. But those who are blessed use it to the best. Here is an example of a designer making a Solar Water Filter.

Solar Water Filter

Gabriele Diamanti has worked on a prototype for a solar powered water filter that comes under appropriate technologies category. The invention is called Eliodomestico which intends to bring safe drinking model to the families in the developing countries at no operating cost. The concept filter is made from cheap and widely available material with simple technological innovation. It’s made from terracotta, recycled plastic and anodized zinc and can deliver 5 liters of fresh drinking water every day and is expected to be an open project, thanks to the concept of open source.

Surge in investment in Wind Mills

Posted on August 29, 2011. Filed under: Alternative |

AS many as 16 windmills with a combined capacity of 800MW of electricity, being installed in the 60 km wide Gharo — Jhimpir Wind Corridor in Thatta District, are expected to go into operation by 2013.

The electricity produced in these windmills (each unit of 50MW) would be supplied to the National Grid.

According to an estimate, the southern part of Sindh possesses the potential to produce 50,000MW electricity through wind energy. Wind energy is now the focus of Sindh Board of Investment which has facilitated setting up of these ongoing projects.

As per official policy, tariff fixed for the wind power would be 10 to cents per kwh for the first 10 years, to be reduced to four cents per kwh in the following decade.

Of the 16 under-construction windmills, three are expected to start production by next year. These are (a) a project of Zoriu Enerji Company of Turkey located at Jhimpir. In the first phase six MW unit was commissioned in 2009 while the project is extendable up to 300MW. (b) Fauji Fertiliser Wind Mill at Kuti Kun Island and (c) China International Water and Electricity Company project at Jhimpir.

The rest 13 units, expected to start operation in Jhampir and Bahmabore by 2013, are: Sapphire Wind Power, Metro Power, Gul Ahmed Wind Power, Master Wind Energy , Zehphyr Power, Lucky Power, Beacon Energy, Green Energy, Kuttikin (Jhimpir), Temaga Generasy, Daoud Power, Sachal Engineering Works, Wind Eagle and Abbas Steel Group.

Besides, six more companies are reported to have applied to build windmills in this belt and have even deposited the required guarantee amount.They are in the initial stage of pre paring feasibilities etc.

The investment in wind energy has been encouraged by Sindh government’s policy to provide following incentives and facilities: (i) leasehold land available for the life of project to eligible investors on attractive annual rentals ( $10 per acre), (ii) long-term (20 year) agreements with the power purchaser i.e. Wapda backed by Government of Pakistan’s sovereign guarantee (iii) guaranteed purchase of all electricity produced by the project for the entire concession period of 20 years with adequate compensation for periods when power purchaser is unable to take up the energy produced, (iv) comprehensive coverage to investors against political risk and risk of change of law through force majeure provisions, (v) guarantee of buy-back of the facility in case of termination of the project, (vi) wind data from various sources to be made available for five years, enabling a great degree of accuracy for the purposes of calculation of wind speed, direction, density, frequency etc, ( vii) coverage of wind speed risk for the pioneering projects based on benchmark wind speed set by AEDB, (viii) development of benchmark wind speeds for Gharo-Jhimpir Corridor, (ix) comprehensive tariff regime on a cost plus basis, (x) fiscal incentives through a zero tax/duty regime.

The only contribution to national exchequer would be through a 7.5 per cent withholding tax on dividends declared across the life of the project, (xi) Attractive return on equity of 17 to 18 per cent – offered under the NEPRA tariff guidelines, (xii) Certified Emission Reductions (CERs) available on a shared basis with the Government of Pakistan, (xiii) environmental issues facilitation by AEDB to investors including EIA and relevant government permissions, and ( xiv) development of standardised project documentation keeping in view the norms of international wind power industry.

China’s ‘solar city’ rushes to catch power boom

Posted on June 23, 2011. Filed under: Alternative, Global, Solar |

BAODING (China): Solar panels jut out of streetlights in China’s self-proclaimed Clean Energy City. Tiny wind turbines twirl atop public buildings. Schools are due to teach students about “green living.” In the scramble to profit from demand for clean energy, this city southwest of Beijing is promoting itself as a manufacturing centre for solar, wind and other gear by transforming into a living showcase of environmental technology.

“Baoding is following a path of ecological civilisation,” a deputy mayor, Zhou Xingshi, told a group of visiting reporters.

Baoding illustrates the intensity of Chinese government efforts to profit from rising global demand for clean energy. Communist leaders are promoting solar, wind and hydropower to curb surging demand for imported oil and gas and see technology exports as a route to cleaner growth and higher-paid jobs.

Chinese utility companies are required to install wind turbines and Beijing has promised to pay part of the cost of solar equipment — a strategy that is driving the rapid growth of Baoding and other supply centres.

China led the world in clean energy investment last year at $54.4 billion, up 39 per cent from 2009, according to a March report by the Pew Charitable Trust. Worldwide, investment rose 30 per cent to $243 billion.

Baoding, 90 miles from the Chinese capital in the table-flat farmland of Hebei province, started billing itself as a renewable energy centre in 2002 after the success of Yingli Green Energy Co, a local startup founded in 1987 that grew into a major supplier of solar panels. City leaders officially declared Baoding a “Clean Energy City” in 2006.

Today, Baoding has two government research labs and 170 companies that produce clean power equipment. They include Zhonghang Huiteng Windpower Equipment Co, one of the biggest makers of wind turbine blades. Other fields targeted by Baoding for development include batteries and power transmission.

Baoding’s clean energy companies had 45 billion yuan ($7bn) in revenue last year, according to the city government. It says the local industry should grow by 30 per cent a year through 2016.

Local authorities work closely with companies, organizing job fairs, providing training and helping to recruit employees through local schools.

Companies also are attracted by Baoding’s “funding resources,” said Lian Shujun, deputy director of the Baoding National New and High-Tech Industrial Development Zone.

Lian gave no details but Chinese companies in favoured industries can receive government support ranging from tax breaks and low-interest loans to free rent in business parks.

Such support has prompted complaints by Beijing’s trading partners that the government is improperly subsidising Chinese companies and hampering market access. The US government said this month Beijing agreed to rescind some policies that American officials said amounted to subsidies to makers of wind turbines.

China already is the world’s biggest producer of solar and wind equipment. Yingli and other Chinese solar suppliers have long competed in global markets because their equipment was too expensive for domestic use. Chinese makers of wind gear are only starting to expand abroad but some domestic producers already are among the world’s biggest due to their vast home market.

The Chinese government says it wants at least 15 per cent of the country’s power to come from renewable sources by 2020. It is spending heavily on grants and other aid to propel technology development.

“The Chinese government is very supportive of the green market,” said Liansheng Miao, Yingli’s founder and chairman.

In a sign of high-level endorsement, Yingli received a 36 billion yuan ($5.5 billion) line of credit last year from state-owned China Development Bank.

Miao rejected what he said was the notion that Yingli, a private company with shares traded on the New York Stock Exchange, succeeds due to government support.

“I am an entrepreneur, not a state-owned entity, so the government would not help me,” he said at a news conference. “What we compete on is our innovation and cost structure.” Yingli’s CFO, Li Zongwei, said it has yet to receive any money from the China Development Bank and will have to submit individual projects to obtain loans. Li said such projects are conducted on “commercial terms.” Other companies in Baoding say business is booming.

A wind turbine factory owned by China Guodian Corp, one of China’s biggest power generators, expects to sell 1,100 units this year, nearly double 2009’s level of 600, said the factory’s deputy general manager, Wang Hongbin.

Wang said all of his factory’s output of 1.5-megawatt turbines was sold in China, but Guodian also has announced plans to expand to the United States by supplying units for a power project in Corpus Christi, Texas.—AP

FFC signs closing documents for wind power project

Posted on June 23, 2011. Filed under: Alternative, Pakistan, Wind |

With the signing of closing documents for the 49.5MW wind power project of Fauji Fertiliser Company in the Gharo-Ketibandar Wind Corridor here on Wednesday, the country is now entering into the era of generating electricity from renewable energy.

The project will be constructed and commissioned within 16 months with an expected cost of $133.5 million, financed by FFC and leading local banks. The wind power generation will help reduce the carbon footprint in the country and improve the national as well as global environment in addition to its economical benefits.

AEDB Chief Executive Officer Arif Allauddin and FFC Managing Director LtGeneral (Retd) Malik Arif Hayat signed the closing document witnessed by Federal Minister for Water and Power Syed Naveed Qamar.

The minister termed the agreement as a landmark achievement in the history of wind energy sector. “With this development, the way has paved for fast development of the renewable energy sector since the whole background infrastructure like tariff, grid code, EPA and IA was in place for projects in renewable energy sector,” Qamar said.

Pakistan offers an investment-friendly and lucrative wind energy market for the investors and equipment suppliers, he added.

He said that Pakistan possesses immense wind resources, especially in the coastal areas of the country, which could not be harnessed for one or the other reasons.

The minister said that the federal government was in touch with the Sindh government for its help in allocating more land for wind project in Gharo-Ketibandar Wind Corridor.

More corridors being explored all over the country, wind masts were being installed in Balochistan and Punjab, he said.

He lauded National Electricity and Power Regulatory Authority (Nepra) for its efforts to give tariff to FFC which would act as model for other renewable energy projects especially wind power projects.

10 million using solar power, NA told

Posted on June 21, 2011. Filed under: Alternative, Energy crisis, Pakistan, Solar |

ISLAMABAD, June 18: Federal Minister for Water and Power Syed Naveed Qamar informed the National Assembly on Saturday that the number of people consuming solar energy in the country had increased to 10 million, adding that recently 4,500 houses in Dalbandin (Balochistan) and Tharparker (Sindh) had been energised with solar power.

Answering a calling-attention notice raised by Syed Zafar Ali Shah, Bushra Gohar, Jamila Gilani and other members about non-supply of solar power for domestic use, he said it was an incorrect impression that the government was not paying attention to the solar energy option.The country had great potential for solar energy generation, he added.

The minister assured the house that the private sector would be encouraged for promotion of solar energy. “We will also encourage import of solar panels.” The minister said the Alternative Energy Development Board planned to provide solar panels to 1,500 houses initially, adding the government would support any step proposed by parliamentarians desiring to utilise his/her funds for supplying solar energy to people.

He said some NGOs had energised 485 houses in Fata and another 2,000 in AJK so far. At present solar panels in the country were being manufactured on a small scale, he added.

Speaker Fehmida Mirza observed that electricity could be saved by switching small villages and street lights over to solar energy.—APP

Rs. 1.36 billion for solar energy tubewells

Posted on June 21, 2011. Filed under: Alternative, Pakistan, Solar |

LAHORE, June 18: The Punjab government has allocated Rs1.36 billion for installation of tubewells to be operated through solar energy for lessening the effects of energy crisis on rural economy.

Chief Minister Shahbaz Sharif said his government was working on various projects of generating energy and Rs9 billion had been allocated for such projects in the next financial year.

The chief minister and his brother and PML-N leader Nawaz Sharif reviewed various projects of generating energy at a meeting here on Saturday.

The chief minister said the country was facing a serious energy crisis which not only leaving negative impacts on industrial and trade sectors but also depriving the labourers and workers of their livelihood. He said power of generating energy had been given to the provinces in the meeting of Council of Common Interests. He said besides projects to generate energy through coal, water, sunlight and wind, a policy was also being evolved in consultation with sugar mills for generating power through trash of cane.

Shahbaz said generation of power through solid waste was also in the pipeline and an agreement of cooperation with Istanbul Municipality had been reached.

He said the provincial government had set up a separate department for completing energy projects expeditiously and these projects would be executed through public-private partnership.

PML-N chief Nawaz Sharif said the energy projects would have to be implemented quickly for running the industries and getting the people rid of loadshedding. He said the private sector should be fully encouraged for making investment in energy sector and there should be an independent and autonomous board consisting of professionals associated with private sector for execution of these projects.

Aga Khan service wins green energy

Posted on June 17, 2011. Filed under: Alternative, Global, Green |

LONDON, June 16: A Pakistani firm that fits energy-saving devices in homes and two Indian companies which recycle waste products into sources of power were honoured on Thursday with major green energy awards.

They were three of the winners at this year’s Ashden Awards for Sustainable Energy, one of the world’s most prestigious green energy honours, each picking up $32,200 prize money at a ceremony here.

The Aga Khan Planning and Building Service was selected for helping families in mountain villages save energy and make their homes warmer through a range of locally-produced devices.

Carpenters and metal workers employed by the company make products including fuel-efficient stoves, water heaters and wall and floor insulation.

The British awards, which started in 2001, aim to encourage the greater use of local clean energy and to address climate change and alleviate poverty.

Ghanaian firm Toyola Energy won the top prize, the Gold Award, for its success in making stoves that burn less charcoal than traditional models and that are accessible to low-income families.

The Aga Khan Planning and Building Service and the Indian firms, Abellon CleanEnergy and Husk Power Systems, were among four other international winners.

“Our dream is a world where access to clean, affordable electricity and fuel can be enjoyed by the poor, transforming living standards, reducing CO2 emissions and easing the pressure on dwindling forests,” awards director Sarah Butler-Sloss said.

“The 2011 Ashden Award winners are making this vision a reality, and their potential for expansion and replication is high.” Abellon CleanEnergy, based in Gujarat state, was recognised for its business of producing biomass pellets from crop waste to fuel industries in the area.

As well as replacing traditional industrial fuels with a cleaner alternative, the business also gives farmers a market for waste products. Husk Power Systems, based in Bihar, was honoured for using a common waste product, rice husks, to produce electricity for remote villages in the area. The Ashden Awards judges said that the novel way of producing electricity provided a reliable supply and was cheaper than alternatives.—AFP

One million homes on solar power in Bangladesh

Posted on June 16, 2011. Filed under: Alternative, Solar |

DHAKA: The number of households in electricity-starved Bangladesh using solar panels has crossed the one million mark — the fastest expansion of solar use in the world, officials said on Wednesday.

In 2002, just 7,000 households were using solar panels but now more than a million households — or some five million people — gather solar energy, said Nazmul Haq of the Infrastructure Development Company. “It’s the fastest expansion of solar energy anywhere in the world,” said Haq, who heads the state-run IDCOL, which provides financing for clean energy projects.

“We crossed the one million threshold more than 18 months ahead of schedule (and) we have set a new target to cross 2.5 million by 2014,” he said.

Rural households in Bangladesh are frequently not on the state electrical grid and so have embraced solar power, helped by NGOs providing panels which can be paid for in small monthly instalments. Some 60 per cent of Bangladesh’s 150m people have no access to mains electricity, with many relying on costly kerosene lamps for lighting. A World Bank report said solar panels had “changed the face of the remote, rural areas of Bangladesh,” by providing cheap, reliable electricity.—AFP

Gemasolar power plant still produces electricity even dark

Posted on June 15, 2011. Filed under: Alternative, Global, Solar |

Gemasolar power plant near Seville in southern Spain is the world’s first solar power plant that can generates electricity during the night. The solar power plant comprises 2,650 solar panels that spread over 185 hectares of rural land with heliostat mirrors for 95 percent of solar radiation on a receiver at the center of the giant plant.
.
The plant is actually a collaborative effort between Abu Dhabi’s Masdar energy company and a branch of the Spanish engineering firm Sener called Torresol Energy. Heat up to 900C is used tanks molten salt heat, creating steam to power turbines £ 260 million station.
.
But, unlike all other plants, solar heat stored in these reservoirs can be released from up to 15 hours in the night or during periods without sunlight. The sun of southern Spain claims rather solar energy during most of the morning allowing the plant to produce clean, green electricity to an estimate 270 days a year, three times more than other solar energy projects. It is planned to generate 110 GWh per year that would be enough to power about 25,000 homes in the region of Andalusia.
