Solar Bridge Mocambinho Will Soon Open

The solar bridge over the river Poti will benefit about 100,000 people in the northern region of Teresina and shorten the distance between various neighborhoods. The project is the State Government, with investments that amount to $ 20 million. At 18h, a show open to the community mark the celebrations for the inauguration.

Standing demand of local residents, the Mocambinho Bridge, as it is known, directly benefiting 100,000 people from neighborhoods like Mocambinho, Buenos Aires, Anita Ferraz, Hagia Sophia, Stone Mole and Socopa.

It also serves the Residential Jacinta Andrade, the largest housing project under construction with funding from the Growth Acceleration Program (CAP), where they will live about 25 thousand people.

"The bridge was an immense and ancient dream of the whole northern area of ​​Teresina now becomes reality. Will certainly bring a great development for our region, "acknowledges Jehovah Lopes, Chairman of the Residents of the Village Firmino Son II, also benefited from the work.

Built under the responsibility of the State Secretariat of Cities, the Bridge will have night lighting based on solar energy. We placed eight poles, each with a card that will capture energy during the day. At dusk, the lamps LED (Light Emitting Diode) will be automatically linked. Even on cloudy days the plates will be able to capture sunlight and use on rainy days the energy stored in batteries.

"In a world with growing energy needs, it is important to diversify the energy matrix and solar energy is expected to be the best alternative for regions that lie on the equator, such as Piauí," said Solano Merlong, state secretary of Cities. "The bridge is vital importance for this region, which has densely populated areas on both the North and the East side, with neighborhoods that are thriving," he said.

Solar energy helps speculators

Favored by lucrative government subsidies, the Czech market of photovoltaics is in full swing. Investors from around the world have clashed over whether to take advantage of this manna, little concerned about the ecological aspects, reports Mladá Fronta DNES.

A guaranteed investment at 100%, with an annual yield of 15%. A dream? No way! Thanks to these conditions that the Czech market of photovoltaics can attract investors from around the world. "Israel, Germany and the U.S. dominate the market," said Jaromir Rehàk, president of the Czech Photovoltaic Industry Association. French investors, directly supported by its government, is also installed in the Czech market.

Given the proliferation of speculative investments, the Czech government decided to reduce the price at which electricity companies are obliged to purchase energy for individuals and producers - more than double the value of electricity charged to customers. But the amendment that this low slow to be adopted by the Czech solar business remains today one of the most profitable in Europe. And this in spite of taking into account that the photovoltaic panels placed in the country are less efficient than the Spanish or the South of France, because there are fewer days of sunshine. And like France, Germany and Spain will soon have to download the purchase price of solar electricity, the Czech market should continue to be very advantageous.

"It's the ecology that motivates us, are the numbers"

Czech companies are essentially to ensure the construction of photovoltaic plants. Its leaders are not environmentalists, but financial managers: "I will not pretend that we are guided by ecological interests. We are particularly interested investors and we are just the numbers," admits Ondrej Valnicek, Global Solar society. However, the ecological sensitivity of governments is important for business because it is in itself a guarantee, at least in today's world, that the states will continue to support renewable energy. The photovoltaic business has also become a major provider of jobs in the Czech Republic. Indeed, the country is one of the most important suppliers of solar technology in the world.

Almost 2,000 people work for companies specialized in the production of photovoltaic panels. The research and development sector employs one hundred people and wholesalers of about 400. In total, it is considered that solar energy "employs" more than 4,000 people in the country. Martin is Director of Somar Schoot Solar, the Czech company that leads the photovoltaic sector: "The Spanish market, the second in Europe in terms of importance, has collapsed. The financial crisis put a brake on investment in major projects." But despite this, says it was convinced that the strong growth of solar energy has barely begun: "The European countries all have very ambitious objectives with respect to increasing renewable energy in the overall energy production."

Nazi bunker transformed into largest solar plant in Europe

It will be Europe's largest of its kind and will warm three thousand homes.

A huge bunker in the Nazi time of World War II, which was in Hamburg city, German, will be transformed into the largest solar power station in Europe.

The structure with a height of new floors, it is a concrete block, with walls over 4 feet thick.

During the war, served as a shelter to more than 30,000 people during the bombing and had anti-aircraft capable of firing 8,000 shells per minute.

Under the 'Daily Mail', the building is to be covered with solar panels that will provide heating to about three thousand homes. There are plans to install an on-site museum, a cafe terrace on the roof.

Earth may receive solar energy directly from space

The International Academy of Astronautics in Paris, released a study this week that says that it will be possible to install solar panels in orbit to power is sent directly to Earth within 30 years.

The survey data are encouraging because they indicate a way to generate electricity without causing too much environmental impact, since the sun is a great renewable energy source.

Even solar power is an old technology, the conversion into electricity is not an efficient enough to replace the common and most polluting sources. According to the study proposal, within the capacity to generate energy is much higher.

The project suggests that several satellites are fitted with huge solar panels, which in turn would be gradually sent to Earth orbit. Thus it formed a global system of power generation, able to provide electricity 24 hours a day with great efficiency.

For the plan to succeed and be sent to the energy consumption in the Earth would be passed on in the form of raiolaser or huge microwave antennas.

While structures on earth would receive the transmitted energy and make the storage and distribution. All this implies high costs, so it would take a lot of investment and government support. Until now, such assistance was not offered.

Solar and wind power for a house with 30 containers

Located in Canada, the stack of containers is being transformed into a large structure entirely self-sufficient. The architecture of 5,000 square meters belongs to Bill and Rosanne Glennon, who are reusing containers where 30 systems will be deployed to transform solar energy and wind energy into electricity and heat inside.

A solar panel electric generator and a solar wind power system will supply the electrical needs of the house while the heating is done by a solar thermal and wood. With up to open space for a garage, there are five bedrooms and a large room.

The rooms are all well divided, while the lower level will be buried to improve the energy performance, while structures that are outside of the house serve as a well that provides access to a series of rooms that are linked to solar and wind power equipment in order to reduce the visual impact of the house.

South America installed Its first CPV solar panel

SolFocus has opened in Enor Chile located in Santiago dependencies. The first solar panel in South America, with CPV (Concentrator Photovoltaic) able to concentrate more than 650 times sun energy at one point. It is able to making about 30% of light into electricity, almost double from a silicon panel which reaches 19%.

The initiative will serve as the basis for the panel installation of another pilot in Calama, which will aim to analyze the radiation and the operational cost of these technologies for extreme radiation and dust. Both systems together generate about 17.6 KW of power.

"The Future of Non-Conventional Renewable Energies is in the Norte Grande. There exists 75% of electricity generation based on coal and solar energy should be sustainable in that area, "said Rodrigo Sáez, general manager of Enor Chile.

The panel uses 20 parabolic mirrors that collect sunlight and photosensitive cells condense into highly efficient, and operates solar tracking and controlling its position to maximize energy production. It also continuously monitors the state of wind to avoid damage and is highly recyclable, since 95% of its components are made of glass and aluminum, which are immune to ultraviolet degradation over time.

"CPV technology has the ability to increase or decrease depending on each project, which is an important factor for dynamic energy needs of the Chilean industry," says Nancy Hartsoch, VP of Marketing of SolFocus. "It can also deliver cleaner energy and low cost to the industry," he adds.

Unlike a traditional panel which occupies five or six acres to generate 1 MW, photovoltaic panels require only 2.5 hectares to produce the same amount of energy, resulting in lower capital investment and less maintenance in time. Finally, it can be deployed on slopes and have up to four times the slope of a conventional one.

3M transparent solar windows to charge your gadgets

Slowly it seems that solar power is emerging and sometimes unexpected forms. In this case, 3M shows a new type of transparent solar panels that can attach to a window literally. The panels have an efficiency such as a square meter is capable of recharging the battery of a current smartphone while receiving sunlight.

The funny thing is that this changes the way we understand the traditional solar panels that until now were composed of large plates difficult to install in specific buildings. With such an invention would be literally invisible panels and open to the possibility of use in a home with an internal battery that is charged during the day, also seem much more simple to install.

The drawback of these panels is that they get 20% less energy than traditional solar panels, but at the sale price will be half. This is interesting, because like any new technology over time reducing the price just as it popularized its use. You can easily imagine the surface of a building covered with these transparent panels without making their presence converted into high walls or electric power generators smaller versions that you can incorporate in cars or as covers for laptops.

The most interesting is that 3M will just show the Japanese sample Ceatec few days ago, but will be available commercially in a few months
