Germany produces more solar energy than 20 nuclear power plants

noreply@blogger.com (Ido Setia) — Thu, 31 May 2012 02:11:00 +0000

Between noon of 25 and 26 days after the production of solar energy in Germany amounted to 22,000 megawatt hours, equivalent to a world record that would produce 20 nuclear power plants at full power.

"Never has a country produced as much solar energy," said Norbert Allnoch Reuters, director of the Institute of Renewable Energy Industry (IWR), Germany.

The same official said that Germany, the European country with more investment in solar, already haunted by several times the 20,000 MW in photovoltaic hours, but achieve 22,000 MW, "is indeed a world record."

In those 24 hours (between noon Friday and noon on Saturday of last week), photovoltaic panels spread across Germany produced 50% of the country's electricity needs.

On average, a year that country can supply 20% of electricity needs in PV production.

Closure of nuclear empowers renewable

Remember that Germany, following the disaster of Fukushima, Japan, initiated a process of decommissioning (closure) of its nuclear plants, having to take refuge now more than ever, in the production based on renewable sources. The option is not strange that the strength of the Greens party in public opinion in general and also of political power.

The choice of PV is costing consumers more than two cents per kilowatt hour. Makes the bill heavier, generates controversy among the most critical sectors, but is reflective of a policy option, which costs a year four billion euros to the Germans, according to accounts of the Ministry of Environment of the country.

Merkel wanted to cut subsidies to solar, but could not

The government of Angela Merkel tried to cut 15 to 30% in fees paid to the production of solar energy, but the proposal was grouted to the upper house of German parliament.

In Portugal due process now calls for cuts in excess rents paid to the electric sector, having already been announced by the end of subsidies (power guarantee) to combined cycle gas, worth EUR 60 million and still to a part of the hydroelectric production subsidies, which amounts have not been fully established.

Solar Energy to Restore Sight to the Blind

noreply@blogger.com (Ido Setia) — Mon, 28 May 2012 09:20:00 +0000

Currently solar energy not only helps improve the environment and health of our planet. But now it also involved in improving the quality of life of blind people? Restore their vision.

A group of scientists at Stanford University, California, USA, developed a bionic eye solar energy using solar energy, the goal is to restore sight to people blinded by retinal degenerative diseases that do not undergo risky operations and without using cables.

It is an artificial vision system powered by sunlight, implemented a super sunglasses, a microchip and a minicomputer under the retina.

The system operates similar to how the work of current solar panels instead of powering a home, it flows into the retina.

Tiny solar panels installed on the back of the eye, a video camera is installed behind the retina, and records what is happening in the eye. The panels to operate in a very small amount of infrared light enough to provide an electrical pulse to the optic nerve to the brain, in the form of visual information.

The solar bionic eye was tested in the laboratory with the retinas of mice. The results were positive, now the next step is to test the technology in humans.

The technology is difficult to understand and more difficult to explain with so little information. It is clear that the bionic eye gift is being tested, hopefully soon know more about this new technology that is more than interesting.

New Design Mini Wind Windpod G1

noreply@blogger.com (Ido Setia) — Thu, 24 May 2012 13:09:00 +0000

This is a new design of wind Windpod mini-called G1, developed by a group of Australian scientists.

The background of this project is about to utilize the small wind that is usually wasted. A great importance since it is the best method to harness wind energy on a small scale at home.

G1 Windpod design is resembles the design of a vertical and horizontal wind turbine that only has a diameter of 459 mm and a length of 2,220 mm. Two of them can produce 1 KW, operates the wind currents from 4 m / s operating with only 12 m / s at full capacity.

These benefits are more than good, the best you can have on the market today. So I think it is unlikely to be replaced by other domestic wind turbines.

The G1 Windpod could easily be incorporated into the design of any house or building, or even install in existing buildings without losing aesthetic. The device can be installed in buildings, houses, roofs, terraces, gardens, entrances and even roads and bridges in advertising or publicity.

For more information about G1 Windpod visit the official site windpods.com

Japan city to restart the reactors

noreply@blogger.com (Ido Setia) — Fri, 18 May 2012 23:38:00 +0000

City management of the Japanese city of Oi recently decided to support the restart of two reactors made of during a maintenance shutdown. An overwhelming majority of members, 11 to 1, voted for the decision. The reason for this is that there is concern that the city will suffer economic damage from the decommissioned power plants. Ultimately it is the mayor of the city that has to take the decision on a restart.

Nuclear power plants which have recently set off for routine maintenance shutdowns in Japan has not started up again. But now the Prime Minister Yoshihiko Noda said that the country needs to start up some of its nuclear power plants for intensive energy in summer months.

Before the earthquake and nuclear accident in Fukushima Daiichi in March last year covered the nuclear power 30 percent of Japan's electricity needs. Last summer, Japan was forced to ration electricity through planned blackouts to deal with the deficit.

Noda has warned that a similar situation may occur this year.

- The Japanese way of life can do it, but not the industrial sector with factories that need a very stable power supply, says Takao Kashiwagi, a professor at Tokyo Institute of Technology, to Majirox News.

- If energy security is not guaranteed, some factories because prepare to move abroad. It will have serious consequences for the Japanese people, says Kashiwagi.

Empire State Building New LED lighting to save 75% energy

noreply@blogger.com (Ido Setia) — Sat, 12 May 2012 06:57:00 +0000

Symbol of Manhattan, the Empire State will gain new lighting bulbs with LED technology. The company owns the building, Malikin Holdings, decided to replace the 400 lights that currently illuminate the upper floors of the skyscraper by 1,200 new devices, which have a total of 68,000 small LED lights.

Besides reducing energy consumption the new technology will allow the manipulation of light to generate special effects. Will be rainbows, waves and light bulbs produced by cross through computers.

The new devices will allow the Empire State Building is lit with millions of different colors. Currently, only 10 colors are used and required seven workers to change them. The different shades are famous in the building, known for its tradition of using colors to commemorate different causes.

LED lamps will mean a saving of 75% annually, since each new device lasts between three and six times longer than traditional bulbs. The expectation is that the new model will be finalized in October.

Transform contaminated hotspots areas for Renewable Energy

noreply@blogger.com (Ido Setia) — Sat, 12 May 2012 02:30:00 +0000

Here is a strange idea, undeniably good: How unproductive land contaminated or polluted site to produce renewable energy. A collaborative project of the DOE and EPA aims to streamline the process for doing this.

The EPA requires that the proposed modernization of the U.S. Land and notes that the initiative "identifies the potential of renewable energy on these sites and provides other useful resources for communities, developers, state, industry and local governments or any person interested in returning to use these sites for renewable energy development. "

The toolkit will be the same for businesses, individuals and municipalities, and should help stimulate the rapid deployment of renewable energy in half a million contaminated sites to be around.

Bloomberg reports that the two agencies focus on new tools for "Evaluation of commercial and industrial roofs, car parks and contaminated land with potential for solar and wind energy." And these tools can be very useful, given the large number of vacancies in contaminated sites throughout the country. Bloomberg follows:

The tools, which include solar and wind "decision trees", will help state and local governments and landowners to identify the best sites without technical knowledge, according to the EPA. The EPA estimates there are 490,000 contaminated sites that cover almost 15 million hectares in the United States, both in urban and rural areas. The reuse of these lands for renewable energy projects can bring economic benefits and other measures.

LED bulb that lasts 20 years released in the U.S. for $ 60

noreply@blogger.com (Ido Setia) — Tue, 08 May 2012 04:27:00 +0000

A bulb that lasts 20 years and costs $ 60 went on sale in the United States this week. The product is manufactured by Philips multinational, which replaced the traditional filament emitting diodes (LEDs).

LED technology increases lamp life but also more expensive merchandise. Philips is offering discounts to some stores to try to popularize the product.

With discounts, special lamp can cost up to $ 20. The manufacturers argue that despite the high cost, the lamp can bring savings in the long run, since it consumes less electricity to operate.

Energy Efficiency

The product won the Bright Tomorrow competition that promoted by the Ministry of Energy of the U.S., aimed at seeking more efficient alternatives to ordinary light bulb of 60 watts with less power consumption.

Philips was the only company that participated in the competition. Their product has undergone 18 months of testing before being deemed the winner. A slightly cheaper but less efficient, LED lamp from Philips is already sold in the United States and Europe.

The main competitor of the LED lamps are fluorescent, which are almost as efficient but cost much less. Governments of many countries are trying to encourage the purchase of energy efficient light bulbs, and to end production of incandescent filaments and high energy consumption.

The 100 watt bulbs are no longer produced in the United States and Europe. The 60 watts are no longer sold in Europe and it being abandoned in the United States. By 2014, the U.S. government wants to ban the production of bulbs of 40 watts.

New Wind Power Record in Spain

noreply@blogger.com (Ido Setia) — Fri, 27 Apr 2012 02:10:00 +0000

On Monday, April 16, 2012, Wind power in Spain was re-record of more than 60% of total energy generated in accordance with REE (Red Electrica Spanish) on Wednesday once again exceeded 18 different brands.

It surpassed the record of coverage with 61.06% of demand across the country. Surpassing the record of being taken from the November 9, 2011.

On Wednesday, 18 to 16:41 for an historical presentation quickly with 16,636 MW, up 11.2% from the previous high, as with the generation of 16,455 MWh of energy generated from one hour to five hours for six hours, 11.5% from the previous peak, and also exceeded the energy generated in a single day, 334,850 MW of 6.2% over the previous record.

Spain is currently one of the great powers in renewable energy, especially solar and wind, and these numbers prove it.

What is unfortunate is that the NEC the National Energy Commission in Spain, published this week on its website that do not expect any growth in renewable energy over the next three years, 2013, 14:15.

The environmental target 2020 reached this year

noreply@blogger.com (Ido Setia) — Tue, 24 Apr 2012 04:27:00 +0000

Svebio think that the government and parliament have to raise the target for renewable energy in 2020th, target of 10 percent by 2020. According to Svebio, its to be reached this year. In order to create pressure for further conversion to renewable fuels mean that the target should be at least doubled to 20 percent 2020th.

- Swedish renewable energy in transport sector was 9.8 percent in 2011, according to the Energy Agency. Now sold that much E85 as the price is very favorable compared to expensive records of gasoline. In addition, the use of biogas and biodiesel. As a result, Sweden exceeds the 10 percent level this year, eight years ahead of schedule, says Gustav Melin, president of Svebio.

- Sweden has for many years been the European leader in the development of production and market for sustainable biofuels. Unclear instruments and too low a goal means that investors are now reluctant to invest in new production of biofuels and developing technology to utilize forest resources to make DME, ethanol, biodiesel and other fuels. The same applies to the plans for biogas production. It is important that government and parliament sends a strong signal so that the biofuels industry can continue to develop in Sweden and so that we can maintain our technical advantage, says Gustav Melin.

CHP will conditions comparable to industry

noreply@blogger.com (Ido Setia) — Mon, 23 Apr 2012 04:21:00 +0000

The government proposes in its spring bill that carbon tax will be removed for all power plants in the EU emissions trading scheme. CHP with district heating would thus have the same competitive footing as industrial cogeneration plants, which is welcomed by industry associations Swedish Energy and the Swedish District Heating Association.

When the CHP plant owned by an industry that is part of the EU ETS, the Government has previously removed the carbon tax on the grounds that it is double regulation. However, if an energy company owns a similar facility has been the subject of both emissions trading and carbon tax paid. Government's proposal means that from next year will no longer be double taxing cogeneration connected to district heating networks.

It is good that the government is. Now we hope that it also will take hold of the property tax for CHP. There has recently reinterpreted Tax Code after 25 years, which will lead to massive cost increases for energy companies, said Eric Thor Power, head of tax and incentives issues in Swedish District Heating Association.

Hybrid Solar Panel

noreply@blogger.com (Ido Setia) — Tue, 17 Apr 2012 10:32:00 +0000

British researchers have created a hybrid photovoltaic panel called Virtu. It can heats water and generates electricity at the same time.

The hybrid solar panels are not affected by ambient temperature and placed in vacuum tubes.

The cylinders can be installed on roofs (lying) or even facades (vertically), leaving the choice of the owner priority: electricity or heat.

The Virtu by Naked Energy is able to generate more useful energy per square meter when compared to conventional panels available on the market today.

A study from Imperial College London indicated that the method of heat transfer made photovoltaic cells generate about 40% more electricity.

Contaminated water seeps into Fukushima sea

noreply@blogger.com (Ido Setia) — Fri, 06 Apr 2012 08:43:00 +0000

Tepco had confirmed leakage of 12 tons of water into the sea

Water contaminated with radioactive strontium would serve to cool the reactors.

The Tokyo Electric Power Company (TEPCO), operator of the Fukushima Daiichi plant, the epicenter of the nuclear crisis in Japan, confirmed on Thursday (5) leak into the sea of something around 12 tons of water contaminated with radioactive strontium, informed public television "NHK".

The picture taken on March 16, 2011 shows the damage to Dai-Ichi nuclear power plant in Fukushima, Japan (Photo: DigitalGlobe)

Workers at American found during the night that the leak of contaminated liquid is coming from a pipe connected to the tank in which to store the radioactive water used to cool the reactors.

The accumulation of thousands of tons of contaminated water from the reactors, the liquid that goes towards the interior of the premises of the plant is one of the main problems faced by TEPCO Fukushima Daiichi.

The company's workers were able to close the valves of the pipeline which stopped the leak, about an hour later, detailed the "NHK".

The operator estimates that Fukushima has confirmed that a significant part of 12 tons of water contaminated with highly radioactive strontium has leaked to the Pacific Ocean through a foundation drain that connects the center with the sea.

In addition, on March 26, the TEPCO also informed of a leak in the water circulation system of reactors 1, 2 and 3 of the plant, which dumped 80 liters of water contaminated with strontium in the ocean.

American Solar Energy breaks record

noreply@blogger.com (Ido Setia) — Wed, 28 Mar 2012 07:47:00 +0000

The U.S. solar energy industry installed a record number of panels in 2011. In total, more than double compared to 2010 and is expected to see strong growth this year, according to a new report.

Solar installers built 1,855 MW of solar cells in 2011 with a total value of $ 8.4 billion. This is an increase from 887 MW in 2010, according to a report by GTM Research and the Solar Energy Industries Association (SEIA).

The fourth quarter hit a record existing installations, which ended up totaling 776 MW. This easily beats the 473 MW installed during the third quarter.

USA was a strong market in 2011 and we expect that there is strong again in 2012, says Shayle Kann, managing director of GTM Reaserch.

Many industry analysts have lowered their forecasts last year between 1,500-1,700 MW, when the incentive was diminishing in the country's two largest markets, California and New Jersey. The figures for 2011 put the United States as the fourth largest solar markets in the world after Germany, Italy and China, according to Kann.

Calculator powered by gestures, operates three times faster

noreply@blogger.com (Ido Setia) — Mon, 19 Mar 2012 03:08:00 +0000

It seems that we are entering an era in which technology is based on gestures to operate gadgets, computers and electronic devices in general. Typically, these interfaces based on gestures are used to handle yourself in a game or other. But in this case, I find the 'Rechner Calculator', a calculator that performs various operations as gestures you make on the screen. The result (as state) is that multiplying by three speed at which perform mathematical operations.

On the screen you find a virtual keyboard with numbers, you can keep pressing on the keys for the digits displayed on the calculator. So far so normal, however when you perform an operation just have to make a gesture on the screen. For example, to add or subtract, drag your finger left or right and when you get the result equivalent to the key '=' is to drag two fingers across the screen from top to bottom. Curiously enough, as seen in the video below and an idea that possibly finish watching exported to other applications typical of a lifetime.

Nuclear cooperation between Britain and France

noreply@blogger.com (Ido Setia) — Sat, 17 Mar 2012 02:24:00 +0000

At a meeting in Paris in February agreed British Prime Minister David Cameron and French President Nicolas Sarkozy on economic cooperation in the development of civilian nuclear power.

Cooperate on Nuclear Power Plant Hinkley Point C

In a statement, Cameron said that the construction of the new nuclear power station Hinkley Point C in Somerset in southwest England will pave the way for the new partnership.

Hinkley Point C will become Britain's first new nuclear power plants in 20 years and the first of a new generation of nuclear power plants.

The French-owned energy giant EDF Energy will be responsible for building and operating nuclear power plant, which currently does not have a definite completion date. A new Rolls-Royce factory in Yorkshire, however, will produce components for nuclear power plant and a national training center for nuclear energy in cooperation with Bridgwater College started in Somerset.

"My goal is clear. I wish that the vast majority of the content of our new plant is designed, manufactured and designed by British companies", says Cameron.

EDF has not yet been granted planning permission for the new nuclear power plant, but the driver's preparatory work on the site has been approved and 700 people in France and the UK are already working on the project, which has a budget of 10 billion British pounds. EDF Energy estimates that the project will provide up to 25,000 jobs.

New CHP from Meva Innovation

noreply@blogger.com (Ido Setia) — Fri, 16 Mar 2012 02:07:00 +0000

ECOS Energy in the Netherlands has placed an order for a pre-planning of Skelleftea-based Meva Innovation. The purpose of the design phase is to examine how well Mevas CHP is able to gasify the feces of Agriculture.

Representatives of ECOS Energy Meva has visited on several occasions over the last year and they have signaled that if the study is successful, they want to buy the first facility of SEK 160 million. Meva designing in its pilot plant test "Holland Fuel" and ensure the minimization of pollution.

Eutrophication in agriculture in the Netherlands is substantial. Livestock emit huge amounts of feces. Therefore, replaces Dutch authorities, the companies that help to destroy the droppings. This is where Meva Innovation with its technology comes into play. According to the company, then this power plant can also produce electricity cost-effectively on a small scale, which means that ECOS can make money on both destroyed the stool as the power plant producing district heat and electricity.

The technique is a Swedish invention called VIPP (Vortex Intensive Power Process) and extracting gas and heat. The gas and the heat can then be used for both electricity and district heating networks.

- We see enormous potential in the pre-planning we are now to implement. We have already been visited by interested parties from several countries. Now we will do everything we can to show the Dutch all the benefits of CHP, says Holmberg, CEO of Meva Innovation.

The first of Meva Innovations cogeneration plant located in Pitea and placed in service now in spring 2012.

Nano-Tree to store solar energy and convert water into hydrogen

noreply@blogger.com (Ido Setia) — Thu, 15 Mar 2012 01:32:00 +0000

Researchers at the University of California at San Diego have built a forest of small trees of nanowires to capture solar energy without using fossil fuels. Solar energy is then converted into hydrogen. The research presented in the latest issue of the journal Nanoscale.

Nano threads are produced from natural materials which plenty on earth, such as silicon and zinc oxide, which makes production technology for a cheap way to produce hydrogen on a large scale.

- This is a clean way to deliver a clean fuel, says Deli Wang, a professor in the Department of Electrical and Computer Engineering, University UC San Diego Jacobs School of Engineering.

The tree structure and vertical segments are crucial importance in order to be able to absorb as much of the solar energy as possible. This is because the vertical structures catch and absorb the light while the flat surfaces only reflects it. This is done in a similar way to the photoreceptor cells in the human retina of the eye catches the light.

Wang's team has mimicked this structure in its three-dimensional forest of branched nanowires. It uses a process called the photo-electrochemical decomposition of water ("photoelectrochemical water-splitting") to produce hydrogen.

The water disintegration is the process consisting in that water is separated into oxygen and hydrogen in order to extract hydrogen. The process uses clean energy without any greenhouse gases as byproducts. By comparison, builds current technologies to produce hydrogen on electricity, often generated from fossil fuels.

- Hydrogen is considered a clean fuel compared to fossil fuels because it produces no carbon emissions, but production is currently not in an environmentally friendly way, says Ke Sun, a graduate student in electrical engineering who attended the project.

The vertical tree structure also maximizes the production of hydrogen. One can liken this to a pot of boiling water. Is the pan on a flat surface, the bubbles must be pretty big to get up to the surface. The nano-tree structure can be very small gas bubbles of hydrogen is extracted more rapidly.

In the long term goal is more Wang's research goes way: to create artificial photosynthesis. In photosynthesis, plants absorb sunlight while storing carbon dioxide and water from the atmosphere to produce carbohydrates for its own growth. Wang's team hopes to simulate this process is also used to capture carbon dioxide from the atmosphere, reducing carbon dioxide emissions and convert it into fuel.

- We try to simulate what plants do to convert sunlight into energy. We hope that our "Nano tree" in the near future may become part of a device that works like a real tree for photosynthesis, says Sun.

Rechargeable via a USB cable

noreply@blogger.com (Ido Setia) — Tue, 28 Feb 2012 04:28:00 +0000

Although the rechargeable batteries are not exactly new, in this case a meeting having a feature that makes them different from other and also more interesting. This is a battery including a USB port on one side so you can connect with a single cable to a computer or USB power adapter.

The advantage here is that you do not need special boots. Just an ordinary wire you would purchase electricity from a number of devices you may have at home or anywhere where you are. As interesting extra, you could also give the reverse use USB connector and use the battery to provide power to other devices through the cable.

Interestingly seems to be a design that was created some time ago. In fact, last year won a design competition, which makes inexplicable fact that you can not find it commercially in stores.

Remote control helicopter remote only with your hands using a Kinect

noreply@blogger.com (Ido Setia) — Mon, 27 Feb 2012 04:19:00 +0000

Microsoft is a giant computer company that throughout its history has been quite controversial, are their products good or bad? Surely there is no definitive answer to that question that satisfies everyone, but what is certain is that one of the best inventions to come out of their labs recently is Kinect, the sensor can detect you visually and recognizing the gestures you make in air.

The last application for Kinect is a remote control mini-helicopter that does not use traditional knobs or drivers. You just have to move your hands in the air to give instructions and get it to rise or move from side to side. The system is capable of detecting movements of hands, head and hips and turn them into three-dimensional movements in the air.

The future of toys? It seems in the near future you will see a number of devices around you that are managed in this way. Just imagine changing channels on the TV, turn on or turn off the oven, open the garage door ... or manage 'alter egos remote robotic repeat your movements. So far the geek side of the matter is the fun of making you feel 'using The Force' to levitate objects in the air.

Almarin presents most cost-effective solar solutions

noreply@blogger.com (Ido Setia) — Thu, 23 Feb 2012 09:37:00 +0000

Almarin, exclusive distributor in Spain of the Carmanah Canadian firm, recently introduced the EG40 and EG80, cheaper solar street lamps of the company. These solutions are designed specifically for the development of certain areas of the world. Its main applications are roads and highways, promenades, parks and perimeters. This 2012, Carmanah plans to launch the EG125 in this line.

The technology used and the programming capabilities of the EG series ensure that its benefits are the highest in the market in terms of lumens / euro. This is a range that allows the company to cover certain markets or specific needs of customers requiring products compatible with good benefits. For example, these models are capable of withstanding extreme temporary conditions, such as 241km / h with gusts of three seconds.

"Both EG are intended to cover the need for reliable and robust solutions for LED markets with developing infrastructure, where the autonomous solar system offers an alternative to better performance than traditional lighting. We hope that some products are well received by governments, private industry and contractors in this market, "said Bruce Cousins, director of Carmanah.

Controlled ventilation with heat recovery

noreply@blogger.com (Ido Setia) — Mon, 20 Feb 2012 04:11:00 +0000

People need air! 20-30 m³ per inhabitant used air must be removed from a house in the hour to keep the CO2 content remains at a low level. A level of 0.1% CO2 in exhaled air is generally considered the hygienic limit. From 0.15%, there is difficulty in concentration, it even loads at permanent health damage.

Also be made for building health must be a change of air. This is with about 0.3 h-1 and is used to measure the discharge of pollutants (eg from furniture and carpets), smells and above all moisture. Contrary to popular still, but perverted ideas "breathes" the house not through the walls, but must be ventilated by openings.

Whereas in the past the leaky houses, so we tried for decades to an ever more compact design, the ventilation heat losses to a minimum. The physiological conditions of the people have not changed. What has changed, however, the behavior of living. It is more a shower and laundry drying in the apartment. Since energy is expensive, it is not always an adequate ventilation through the windows. The result is moisture in the components and mold growth on cold surfaces. With up to 40% the proportion of recent decades is estimated energetically modernized buildings that are infested with mold.

Often underestimate the amount of heat loss through ventilation. Was it in a building from 1900 with furnace heating only 10 percent of the total losses, so they reach a well-insulated new construction be 50 percent or more. Even a well-insulated house needs a change of air, making each more is ineffective in insulation.

The solution lies in the controlled ventilation with heat recovery. In a central unit of the Free drawn in from the outside air flow and the exhaust air stream can be played out. They exchange in heat exchanger 90% of their temperature difference against each other. At 20 ° C inside, outside 0 ° C is such a supply air at 18 ° C in the apartment. The ventilation heat losses are minimized, the hygienically necessary air exchange is ensured, as required by the DIN EN 1946-6 and common sense.

There are also decentralized solutions that are suitable for retrofitting in difficult situations. Many manufacturers have distributed solutions in the program, which emerge from a core hole in the outer wall of a room air exchange. However, in these devices is limited due to space reasons, the recovery to about 60%.

For the right solution for your home, you ask a plumber or a home ventilation technology planners. Do not forget that air is a food of which we can not do without 3 minutes!

Vento group creates system to purity biodiesel to 99%

noreply@blogger.com (Ido Setia) — Mon, 13 Feb 2012 02:26:00 +0000

The Valencian company Vento Group has developed a system that allows a biodiesel with a purity greater than 99% from a mixture of FAME (Fatty Acid Methyl Ester) from low-quality raw materials as oleins, fats animal oils, fried and impurities from the oil refining process.

So far, companies using this type of raw materials obtained a biodiesel with a purity of about 90-94% what was below the 96.5% required by European regulations on motor fuels (EN 14214)

The facility developed by Grupo Vento combines the processes of high vacuum evaporation heat transfer for energy recovery, achieving a high yield process. In this way companies manage biofuel sector improved its production processes to ensure the viability of the final product because the purity of 99% places them within the European standards and opens new markets.

Currently in the process of transformation of fat into biodiesel sector companies increasingly encounter more problems to find a commodity that can fulfill the dual objective of achieving a good final product quality and adjust their operating costs to ensure the viability of the industrial process. The raw materials of good quality refined oils of soybean, palm or jatropha biodiesel results in a high-quality but high cost. Conversely companies that use poor quality raw materials like oil industry, the oleins or animal fats had the problem that the final product obtained was below the standards required by European regulations which will greatly reduced the market. With this continuous distillation process will benefit both companies that will increase the value of your final product, as consumers and that will increase the number of liters per year of biofuel suitable for use in automotive applications.

Vento Group has already installed the first distillers in some industries as BIOCARSA, in Cuevas de Almanzor, Almeria, plant with a treatment capacity of 1,500 liters an hour.

According to a recent study of IDEA, the heating is responsible for 47% of energy consumption of Spanish households, followed by appliances and hot water. In this scenario, the heat pump is emerging as an alternative to traditional heating oil and gas, providing greater energy savings and consequently, greater cost savings by year end.

According to company data Daikin, a leader in climate control solutions, the heat pump can save up to 1,086 euros a year on heating in an average household. This average was obtained from a comparison made between spending on kw / h of heat pump (namely Daikin Altherma system) compared to other conventional heating systems (boilers, gas, diesel and electric) to an average housing 100m2 located in Madrid.

Specifically, taking this reference, the use of a heating system based on heat pump (Daikin Altherma) is € 392 / year compared to the € 696 / year of natural gas heating, the € 1,241 / year of heating oil and € 1,478 euros a year on average for electric heat. As such, with the heat pump can be achieved savings in heating a 44% relative to natural gas of 68% compared to the oil boiler and 73% compared to electric heating.

This is possible because the HVAC Heat Pump can save up to 30% of energy, thanks to its high performance in relation to other traditional heating systems. Similarly, the use of new generation refrigerants that can work in colder environments, as is the case of R410A, and the incorporation of the inverter technology, have helped to increase the performance of these systems.

Furthermore, it should be emphasized that the heat generated by the heat pump is considered aerothermal, renewable energy and totally free from the outside air. The heat pump converts this energy into useful heat to achieve a comfortable temperature in the home, even on the coldest days of winter. All this, with the advantage of being a versatile system, as well as heating, cooling provided to heat the home at a suitable temperature during the hottest months.

Depending on the model and conditions, a heat pump generates about 3 kWh of useful heat for every kWh of electricity you use. This means that about two thirds of the heat needed to warm the building is free. Similarly, it is estimated that a heat pump heating with an efficiency of up to five times higher than that of a traditional heating system based on fossil fuels or electricity, even with really low temperatures (-25 ° C outdoor temperature). And all without direct emissions of CO2 into the atmosphere.

Finally, note that the heat pump is very easy to integrate with other forms of renewable energy such as solar thermal. Thus, it uses the sun's free energy to transfer heat (using a high-efficiency collectors transform solar radiation into heat shortwave) to the hot water tank, using this energy and thereby maximizing the efficiency Energy Heat Pump.

Thus, the savings, both financial and in CO2 emissions to the atmosphere, soar, making it a highly efficient system.

The future for offshore wind seems more promising than ever. They come to talk about their renewable energy and do so with a technology should not be underestimated, particularly as regards the discussion of employment: by 2030 there will be about 300,000 workers engaged in the business. The estimates are contained in the last report issued by trade associations.

The production is expected to come to 141 GW, a quantity that is calculated to meet the needs of 130 million households. From this particular branch of wind should come a share of electricity amounted to 13.1% of EU demand. This growth is based on completed projects in the areas of the North Sea and Baltic Sea and those in "during construction" in the seas of Great Britain, Germany and Belgium. In these areas in particular, will rise from 5.6 GW wind farms.

The same industry associations, however the data speak "potential", which will require some important conditions to be confirmed: in addition to the request for additional financing to investors to give "oxygen" to projects, the positive expectations may be invalidated by certain defects on the an employment and logistics, in particular with respect to submarine cables and specialized staff.
