Solar storm 2012: Solar flares can create storm

2012-01-24T06:09:00.000-08:00

Solar flares may make news in the year 2012. Meanwhile you can watch solar flare tonight. Many scientists say that it can create storm in the area where it will be visibleA NASA report has said that a M2-class solar flare is heading towards earth. This may bring another great moment for sky watchers who spend nights trying to see small meteors on some given days. The solar flare that originated from sun, two days ago may show up on skies tonight.A NOAA report suggests that the flare was caused by Region 1401. Another flare was fired by another region on the sun, but that may not reach the earth.Solar flares send out bursts of electromagnetic energy that can occasionally disrupt communications and electrical systems.

For the past several years, the sun has been at a quiet end of its cycle and only recently has gotten more active. Solar cycles go in an 11-year period. This cycle has had fewer storms than usual for this time in its cycle. But that may be changing.Meanwhile the weather experts say that the geomagnetic storm created by the flare that originated from sun may cause severe storm in some areas.There have been predictions of devastating flare originating from the sun and doomsayers claimed that such flares may destroy many cities on earth. Some NASA-funded studies have earlier talked about a “Space Katrina” flare or coronal mass ejection that would devastate modern civilisation, bringing down power grids and frying satellites en masse. The report suggested that the flare may cause food to rot, trains to stop midway in its tracks and traffic gridlocked. The report also suggested that it may cause severe disruption in telephone and internet services.But then there are other experts who say that this is too far fetched and bleak scenario. They also suggest that there isn’t enough energy in the sun to send a killer fireball 93 million miles away to destroy Earth”.A solar eruption is followed by a one-two-three punch, said Antti Pulkkinen, a physicist at NASA's Goddard Space Flight Center in Maryland and Catholic University.'The whole volume of space between here and Jupiter is just filled with protons and you just don't get rid of them like that'Doug Biesecker, physicistFirst comes electromagnetic radiation, followed by radiation in the form of protons. Then, finally the coronal mass ejection - that's the plasma from the sun itself - hits. Usually that travels at about 1 or 2 million miles per hour, but this storm is particularly speedy and is shooting out at 4 million miles per hour, Mr Biesecker said.Plasma causes much of the noticeable problems on Earth, such as electrical grid outages. In 1989, a solar storm caused a massive blackout in Quebec. It can also pull the northern lights further south.But this coronal mass ejection seems likely to be only moderate, with a chance for becoming strong, Mr Biesecker said. The worst of the storm is likely to go north of Earth.
‘Dark gaps in the daily arcs are caused by cloud cover, whereas continuous bright tracks record glorious spells of sunny weather. Of course, in June, the Sun trails begin higher at the northern hemisphere's summer solstice.‘The trails sink lower in the sky as December's winter solstice approaches. Last year's autumn was one of the balmiest on record in the UK, as the many bright arcs in the lower part of this picture testify.’

Organic solar cells with improved energy efficiency

2011-11-23T00:29:00.001-08:00

The chemist Guillermo Bazan and Alan Heeger of the University of
California at Santa Barbara have developed a novel low molecular
weight compound, is to make the organic solar cells far more powerful,
Technology Review reported in its online edition. The prototype comes
at an efficiency of 6.7 percent. Bazan expects it to increase to 9
percent. Thus the cells would convert light into electricity more than
already on the market products such as "Power Plastic" by Konarka,
whose peak value is currently at 8.3 percent.

Although their efficiency is lower by about one-third than that of
conventional silicon cells, organic solar cells have a major
advantage: The molecules that make up its light-collecting layer, can
be in liquid form inexpensively imprinted on flexible substrate films.
Solar cells are thus possible, which are lightweight, flexible and
versatile.

But even if Bazan and Heeger at the new material is a breakthrough
that is likely to have organic solar cells on the market hard, if the
price of silicon cells continues to drop. "Your performance and
service life can not keep up," Yang Yang, says materials scientist at
the University of California at Los Angeles. Yang and his company is
Solarmer primarily on polymer-cell tests in the laboratory but also
small molecules.

The work of Bazan and Heeger, however, show the potential of this
class of materials, says Yang, who trusts her an efficiency of 15
percent - at least in laboratory prototypes. On speculation about
prospects for solar cells made of small molecules Heeger want to get
involved yet. "We should take seriously, but now," he affirms.

Solar park goes online Sukow: More renewable energy

2011-09-02T07:48:00.001-07:00

Region Parchim | 02.09.2011 - 13:14:51
Parchim / MVticker. With the Solar Park Sukow (Parchim) one of the largest facilities in the country was created to generate electricity from solar energy. After a construction period of about three months the work was completed today. "Renewable energies are a great opportunity for Mecklenburg-Western Pomerania. With projects of this kind we can push forward the expansion of decentralized renewable solar energy supply and consistently. So the people of Mecklenburg-Vorpommern directly benefit from the expansion of renewable energies, "said Construction Minister Volker Schlotmann Sukow today.

The solar farm was built on a former landfill site and along the railway line from Schwerin to Crivitz and covers 31 hectares. The 48 000 solar panels will generate 10.5 million kilowatt hours of electricity per year. With the power to about 3,700 households. Thus, the solar park is one of the largest in Mecklenburg-Vorpommern.

Schlotmann also praised the region's participation in the project. "Residents of the region can invest in this asset and share purchase. This shows how to open up new perspectives for the development of renewable energies for rural areas. And they can spot a contribution to the energy revolution, "said Schlotmann. For citizens, there is a right of first refusal for the shares of investment. Nor can the community hope to additional rental income and business taxes.

In 2010, in Mecklenburg-Vorpommern 4100 million kilowatt hours of electricity from renewable energy sources, eight percent more than in 2009. So that renewable energy had a share of 46 percent of electricity production. "We want to increase this share significantly in the coming years," said Schlotmann. The electricity generated from renewable energy sources, especially wind power and biomass, as well as photovoltaics. Photovoltaic systems have 2010 around 113 million kilowatt hours of electricity fed into the grid. Their share of green electricity production could be doubled to 2.7 percent.

This important contribution to the issue of renewable energy describes the technical and economical requirements of mass-produced solar thermal power plants, from the different types of power plants to the development needs and a massive development program. The authors - renowned and experienced experts in the field - show that solar thermal power plants, because of their simple technology, are easy to build with high production rates and therefore can play a substantial role in the rapid substitution of fossil fuels. On the basis of solar thermal power (using long distance transmission) and coal from substituted coal plants, a future energy system is described supplying gas and liquid fuels. This is the first discussion of a complete concept, of a crash-strategy, for the partial replacement of oil and natural gas.
