Solar Cells from Tobacco Plants May Be a Reality Soon
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. What do you think?
Biofuels, PhotoVoltaics, Solar Power
Wind power has recently received a nice boost as one of the hottest forms of energy on the market. When comparing the recent market growth against all forms of energy, both renawables and non-renewables, wind turbines seem to be jumping to the head of the pack. While it still has a way to go before it catches up to solar, it is gaining ground rather quickly. Something that will help pick up the pace even further is new technology that is coming from FloDesign. Their truly unique wind turbine is actually based on the design of a jet engine instead of the traditional windmills that we see all across the country. Their concept seems to be a simple one, but it extremely effective. 
People are getting more and more excited about green automobiles, so it was kind of surprising to see such a neutral reaction to the Fuel Cell Car by Riversimple. While this project has a very interesting slant from other cars that we have seen in this niche, it was met with a very lukewarm reception and things have not really heated up on in yet. However, the Riversimple Fuel Cell Car continues on and will hopefully be available for release in the next few years. 
Few people that are ripping around the streets in today’s gas guzzlers will remember wood-powered cars, but if things continue the way they are, they may be lucky enough to see one pull up next to them at the light. Wood-powered cars are starting to pop up again as yet another means of saving our fossil fuels. Wood-powered cars made their first big appearance in Europe during WWII. A wood gas generator was attached to the vehicle so that the drivers could save fuel, yet still keep their cars operational. Looking at some of the pictures from back then, the cars literally look like they have a wood-burning furnace attached to the hood or trunk. It may have looked funny, but it was actually very efficient. 
Consumers surely remember the days of seeing pictures off all the funny looking electric cars. They looked like something out of the Jetson’s and were hardly something any of us would be caught dead in. Say goodbye to those old stereo types because the Volkswagon E-Up is raising the bar in electric car technology. 
With all the talk of going green, the question had been thrown out many times if there will ever be a time that we can use nothing but renewable energy to power our world. A small island in Denmark is trying answer that question with a resounding yes as they power up every single day via nothing but wind power. The Danish island is the ideal setting as the wind literally never stops blowing. The North Sea offers the perfect opportunity to capitalize on the winds that come off of the sea and for them to use wind power as their primary source of power. As a matter of fact, the wind power that they are using is their ONLY source of power. 
The carbon footprint that automobiles leave is about to change, and that change is going to happen much sooner than we think. While it is unlikely that the Micron will replace every car on the road, it will present a very interesting alternative to daily travel. This unique design is eye catching and more importantly, totally emissions free. Make no mistake about it, the Micron is the future of the automobile. 
Renewable energy is one of the hottest things on the market right now but until recently, solar power has been getting most of the attention. While there are plenty of techno gadgets, like solar briefcases and solar laptop chargers, that can have solar power on the run, very few if any items exist for other sources of renewable energy to become portable. The foldable wind generator has all the right ideas, but may still be just a bit ahead of its time. 
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). 
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. 
Reputed companies are always conscious about their brand image and what a great way to build great brand by taking clean and green route! Bell Lab is the division of the Alcatel-Lucent. Currently Alcatel-Lucent is trying to invest in their communications networks to make it 1,000 times more energy efficient. They have launched a five year program known as "Green Touch." Members affiliated with the Green Touch are AT&T, and China Mobile from industry; MIT and Stanford University from the academic world; and The French National Institute for Research in Computer Science and Control from government. Industrial laboratory members are Bell Labs, the Samsung Advanced Institute of Technology and Freescale Semiconductor. The project has received the nods of ascent from United States Secretary of Energy Steven Chu and the British, French, South Korean and Portuguese governments. 
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." 
UK's energy and climate change minister, Lord Hunt shares his opinion, "We recognise that the North Sea has huge resources, we are exploiting those in the UK quite intensively at the moment. But there are projects where it might make sense to join up with other countries, so this comes at a very good time for us." Lord Hunt is talking about several North Sea countries that have coalesced for a good cause. They are aiming to create a clean and green supergrid. This supergrid will be connected to wind farms of Scotland, solar panels of Germany and hydro-electric dams of Norway. This project will be ready soon and then the first green European electricity grid will become a reality. They have expanded a network of thousands of kilometers of highly efficient undersea cables. These network cables will cost around €30bn. This way renewable energy generated in any of the North Sea countries will be available to many. 
Today’s twin goals of keeping fit while doing something good for the planet by creating electricity without any pollution come together in a product that has been around for over ten years – The Pedal-A-Watt Stationary Bicycle Generator. Use your bicycle along with the Pedal-A-Watt Stand (it takes 15 seconds to drop your bike in) and create anywhere from 100 to 300 watts depending on how strong you are. 
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. 
Researchers at the Cornell University have taken inspiration from nature and tried to imitate the swaying of tree branches. So what is the difference between natural swaying of trees and energy-harvesting tree created by Cornell University researchers? The flapping leaves developed in the laboratory generate energy which can be utilized by us. They are christened as the “Piezo-tree.” The synthetic leaves of the “Piezo-tree” are connected to a piezoelectric stem. The whole exercise till now appears to be low-cost, and easily scalable. 
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%. 
Nowadays students are not oblivious to the hazards of global warming. They are quite keen on pursuing a ‘clean energy’ career. Now the concern about climate change is stimulating more undergraduate students to show interest in science and engineering. We can watch the trend of the rising interest in renewable energy. As leaders from various schools such as Arizona State University, Indiana University and the University of Colorado confirm that energy and sustainability are the hottest topics for their students. But another fact which can’t be guaranteed is whether their keenness for renewable energy will remain so into graduate school and further on in life. 
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.
