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.

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

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

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.

Italy will add 7 GW of solar power on the grid next month

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

Italy as the world’s second biggest solar market in 2010 will add 7,000 MW of its solar capacity by June this year. The addition of solar capacity of 2,300 MW in 2010 will be a new record for the biggest production in the middle of this year.

Government incentives for solar power will soon be over in June. The government hopes more people to make use of solar power system for their electricity need, so more solar capacity could be produced naturally in the coming months.

Italy government’s decree last year has approved the extension of generous incentives to the projects connected to the grid until the end of June 2011. The termination of the program aims to ease the burden on consumers who pay incentives for solar program in their electricity bills.

In the last year, about 200 MW of 4,000 MW turned operative in December 2010 and its expected about 3,000 MW of solar capacity will be connected in the end of Juni 2011.

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
