Solar Power

As the world continues its quest to use less fossil fuels, the latest possible solution comes from the most unlikely of sources: the tobacco plant. This latest news comes from the University of California, Berkley. It will be nice to see tobacco used for something other than lung cancer. This new discovery is based on the possibility of literally programming the cells of the plants to get solar cells from tobacco plants. The science behind it is actually pretty simple (at least in explanation form) and pretty amazing. By using a genetically engineered virus, scientists were able to literally transform the cells of the plants to create synthetic solar cells. No Comments

What can a scientist do with salad dressing apart from telling you that it increases the taste of salad manifold? But that’s the beauty of this profession. As Newton could give some theories when he saw an apple falling from a tree, salad dressing can inspire scientists towards a brand new type of solar cells. The researchers managed to create a cheap, efficient and very simple method of making solar cells. The USP of these solar cells is that they self-assemble on a variety of substrates. The new technique draws parallel from the fact that oil and water don’t mix at all. Another unique fact is forces the elements of electronic components for example solar cells assemble themselves at the boundaries between the two types of liquids. This work was recently published in Proceedings of the National Academy of Sciences (PNAS). 7 Comments

If UAVs starts running on the solar system, then it will save lots of expensive fossil fuel and the add-ons in the form of greenhouse effects. Researchers at the Queensland University of Technology are working on a model of a solar-powered unmanned flight system for round-the-clock surveillance. They have christened their baby as the Green Falcon. This solar UAV aspires not only to save lives but millions of dollars too by using the most up-to-date green technology. Queensland University of Technology is aiming to make the services of this unmanned air vehicle commercially available within 24 months following successful flight tests. 2 Comments

Researchers at the University of Nevada, Reno are developing a solar technique that will take care of the ecosystems of terminus lakes around the world. This new solar distillation system will help in removing the salinity of the lake water. This will be possible with the help of a specialized low-cost solar pond and patented membrane distillation system deriving power by renewable energy. Francisco Suarez is a doctoral student in hydrological sciences at the University. He is of the view, "These lakes -- hundreds worldwide -- such as the Great Salt Lake, the Salton Sea, the Aral Sea and Walker Lake here in Nevada, see a decline in water levels and an increase in salinity from both human and natural processes. The high levels of salinity are dangerous and unsustainable for aquatic life." 1 Comment

Researchers speak in unison that if we develop the capability to harvest 40 minutes of sunlight falling on the entire earth, we can provide energy to the whole population of this planet for about a year. But we are successful in trapping just 1% of that energy till now. Scientists and industrial designers are continuously engaged in research so that they can create mechanics and systems that can harvest solar energy in a better way. That will help in dispelling the doubts about alternative energy resources. 7 Comments

Tiny, glitter-sized solar cells have been developed by the Scientists at Sandia National Laboratories. It might turn out to be the perfect alternative energy preference for the holiday season. This project is funded by the American government. The dimensions of the snowflake sized crystalline-silicon photovoltaic cells are merely 14-20 micrometers thick and measure 0.25 to 1 millimeters across i.e. only 10% as thick as regular ones. They also consume an estimated 100 times less silicon to produce the same amount of electricity compared to standard solar cells. Their efficiency level is 14.9%. 6 Comments

Robins has time and again been considered as a pioneer in testing alternative energy technologies. Recently they have installed a solar panel which is a matter of curiosity. Their installed solar panel assumes the dimensions of a drive-in-movie screen. It is the shining example of the state-of-the-art technology. At peak hour it generates 25 kilowatts of electricity. 7 Comments

China is often dubbed as a heavy user of fossil fuels and polluter or a climate killer. Because it meets the 70% of its power needs by exploiting coals. But they are making changes on the environment front too. Slowly and steadily they are choosing wind and solar power as their source of energy. China has earned the distinction of having the world’s largest solar-powered building. It is situated in Dezhou, Shangdong Province in northwest China. The building covers an area of 75,000-square-meter. The office building is modelled after the sun dial structure. 3 Comments

The World Bank will invest $5.5 billion for North African solar power projects. They have announced that initially World Bank will put in $750 million dollars from the Clean Technology Fund with the remaining amount will be arranged from other sources. World Bank is expecting to complete these projects by 2015. They are willing to include five countries in this project and hoping to triple world wide concentrated solar power technology (CSP) capacity. This relatively new technology uses mirrors to concentrate sunlight onto a single point, heating water to drive turbines. Construction of the 11 facilities in the project is scheduled to begin in 2011. It is expected that the North African project will generate a total of 900 MW in capacity by 2020. 4 Comments

We are registering good progress in the field of alternative energy. Scientists and researchers are working tirelessly to come up with newer and better alternatives to fossil fuels. Scientists are also trying to apprehend the future problems related with clean and green fuels, for example, cleaning of windows and solar panels and expanded battery storage capacities for the next electric car. Nature Nanotechnology has just published the New Tel Aviv University research. The research findings deal with a breakthrough in assembling peptides at the nano-scale level that could make these futuristic luxuries come true in the coming years. 1 Comment

Villagers of Wagharwadi till now knew how to make most of the daylight. This village is in Maharashtra, India. They used plastic plates as skylight. This kind of skylight helped women to recognize the ingredients stocked in their kitchens. After evening, villagers depended on candles and kerosene lamps. If some emergency or calamity forced to get some more light in the night they resorted to burning dry twigs. People living in the developed countries would find it a bit difficult to imagine such a situation. 7 Comments

If we try to observe which states are going solar we will find an interesting bend. Many states in U.S.A. are not the sunniest one but still they are opting for solar energy. It’s natural for sunny California to go for solar energy. South Florida is a focus of solar activity because it enjoys a balmy weather and a progressive bend of mind. If we study the energy maps of parts of the Phoenix we will find that they are also opting for the solar energy. If we care to look into the demographics we will find that people want clean and green energy like solar energy while living in shady area. Why? The answer lies in the economic status. They have money to spend and possess progressive thinking. 14 Comments

You can think of it as origami -- very high-tech origami. Researchers at the University of Illinois are working on the same good old silicon but they are taking an entirely different route. They are working on thin films of silicon applying two processes one is photolithography and another is self-folding process driven by capillary interactions. This technique results in the three-dimensional, single-crystalline silicon structures. Their films are only a few microns thick. Their greatest strength is mechanical bendability that is not possible with thicker pieces of the same material. 2 Comments

Industrial designers are dreaming of a project like this for a long time. They wanted a solar powered parking lot which can sustain itself and light up its own lights. They also want future electric vehicles to be charged at the same place too. The spirit of Isla Vistans can be imitated. They turned out in large number for the inaugural ceremony of a new parking space at 881 Embarcadero del Mar. What was so special about a parking lot? The parking lot was constructed on a half-acre site. The interesting part is the same location used to house a Chevron gas station. Isla Vista, Santa Barbara County, California, has registered its presence in the field of clean and green energy. They established their first solar-powered car parking lot. 27 Comments

Two things are certain for the future: electric cars will become more popular and solar power will continue to grow as a viable source of energy. Because of this, the world is looking to industry leaders not only in the energy business, but to other major corporations that can have a major impact on the world’s power usage. Dell has stepped up to the plate and hopefully the Dell solar trees parking lot is a sign of greater things to come. The Dell solar parking lot by Envision Solar is a very innovative way that Dell has implemented solar powered lights and it is something that is immediately making an impact. The solar trees serve not only the purpose of gathering the suns energy as a viable energy source, but even provides shade over about 50 parking spaces as well! The lot was made viewable from the highway so Dell can let everyone know that solar power is the way to go. 3 Comments

When we think about going solar we make a mental picture of large heavy panels adorning one’s rooftop. But researchers are trying to get rid of bulky solar panels. They are aiming to achieve this feat with the help of zinc oxide nanostructures grown on optical fibers and coated with dye-sensitized solar cell materials. Researchers at the Georgia Institute of Technology have built up a new kind of three-dimensional photovoltaic system. This three-dimensional photovoltaic system will not be heavy and it will not occupy a place of prominence on rooftops; it can be hidden from the view. No Comments

Researchers and scientists are putting on endless effort to make the sources of energy clean and green. There are many devices in the market that run on solar energy. The alternative energy atmosphere is charged with anticipation and excitement. But till now one of the biggest dampeners in green energy scenario is the prices. Fossil fuels are available cheaply all over the world. But solar, wind, geothermal or biofuels are still expensive and out of reach of commoners. 5 Comments

It seemed like it would only be a matter of time before Toyota would jump into the market of using renewable energy to charge a car and they have done so in a big way. The solar charging station by Toyota will be put on display at the Tokyo Motor Show 2009. While there are other charging stations on the market for electric cars, the fact that this one is solar powered has the industry abuzz in anticipation. The solar charging station by Toyota almost looks like something that you would have seen in one of the old sci-fi movies, but this is the real deal. It works by collecting the suns energy through solar panels and then stores the energy in a battery that is later used to charge and power the vehicle. This is just another great innovation that is pushing our world to a 'greener' lifestyle and will use renewable energy in yet another every day application. 7 Comments

You see the last bar of power and panic starts to settle in because you are about to be cut off from the outside world. Worry no more because the portable solar charger Novacell is going to give you all the solar power that you can handle to charge up your devices. 6 Comments

We still have to miles to cover before solar power can replace the fossil fuels and become a cheap and effective solution for common folks. But it is indisputable that sun is the single greatest fuel source we can harness to our advantage. Solar energy can leave its impact on a global scale in a significant manner. Everyone who is blessed with a hot, sunny spot by the grace of the nature could one day power their homes entirely by photovoltaic roofs. Even it seems possible that large solar arrays could feed power plants that keep the lights on in entire municipalities. 8 Comments
