Pratima Kalra: Mercedes Benz F125 Concept vehicle powered by fuel cells Whether a leak out of some facts about automobiles before launch creates more intrigue or spoils the punch can be mooted hard. The biannual Frankfurt Motor Show gives the big brand car makers like Mercedes Benz, BMW, Volkswagen, etc a platform to display their lavish plans for the future in terms of both design and technology. Therefore, the perfect platform for Mercedes Benz to launch its all new hydrogen pumped F125!, a concept aimed for 2025 CL-class. Picture Gallery 2011 Mercedes Benz F125 Hydrogen Gullwing 2011 Mercedes Benz F125 Hydrogen Gullwing Concept Vehicle Powered by Fuel Cells Automobile innovation no longer gives jitters to people; they know if you can think something, you can actually deliver it. We’ve digested the evolution of electric cars and now maybe it’s time for something more alluring. Thus, if Mercedes Benz claims that F125! will be fuelled by hydrogen with an engine that will bail out 231hp and it will take just about 4 seconds to reach to 62mph, with a top speed of 137mph, the facts will be well taken. To top it, the car has been designed to consume just 0.79 kilograms of H2 per 100 kilometers. As for the design details of F125!; it takes inspiration from the F800 with its fluid form and gullwing door concept. This gives this new Benz poise and elegance and also renders is useful for congested car space in cities. Just like a few other Mercedes Cars like McLaren, the undercarriage is made of a combination of carbon fiber, aluminum and plastic; using their comparative advantage to come up with something more solid. A gas tank made of carbon fiber is fitted to hold hydrogen to the capacity of 700 bars. Also it gets some power from an onboard 10kWh lithium-ion battery that would permit it to travel approximately 31 kilometers. Whether the 125 years of existence and success of the dynamic Mercedes Benz is once again going to dazzle the audience with its unique mix of technology and design all encompassed in the new gullwing F125! at the Frankfurt Moto Show, will be a thing to follow up with.

Comments Off on Bionic-Arch: A green gift for the City of Taichung by Vincent Callebaut

Pratima Kalra: Bionic Arch Designed by Vincent Callebaut History has witnessed that whether it was great warriors or was it Emperors, they all wanted to become immortal and leave behind their mark in some tangible form that will be remembered for centuries after they leave earth. Picture Gallery Bionic Arch Bionic Arch Designed by Vincent Callebaut Most of us enjoy meaningful gifts that add some value to our lives. This is an era of value addition; especially if the purpose behind gifting is social and it will collectively affect many people. Thus, keeping in mind this ideology, the Government wants to give Taichung a special gift that will not only be contemporary but will be marveled by people for times to come. The government has acknowledged the newness and freshness of the architectural feats of Vincent Callebaut and has assigned them to use their expertise in spatial inventiveness that will foretell the destiny of times to come. Creativity cannot be legitimized by eligibility criteria. Every new creation has its own definition and dimensions. The only binding factor is nature and humans and if their needs are being met with coherence, the purpose of creating and innovating is well justified. Thus the government is promoting freedom of thought and has allowed Vincent Callebaut Architecture free play to design a unique skyscraper that will personify the life of the people of Taichung. The clear message that this skyscraper, dubbed Bionic-Arch, would epitomize is that humans and Mother Nature can always live in harmony; all it takes is some cognitive logic and the right inspiration for the same comes from the world around. The blue of the sky, the green of the trees, the crystallizing of water with sun beams, etc. will give a final face to the structure that will merge to become sublime. To the distant eye the structure will not stand out for attention but for reverence, hence accomplishing the government’s dream of spreading awareness about green and its benefits to mankind.

Comments Off on 10 Genetically engineered life forms promising a greener planet

Shaheen Akhtar: e.coli e.coli The advancement in science has allowed biologists and researchers to know more about the functioning of enzymes. Studies revealed that the structure of DNA can be changed by working with enzymes which are responsible for this. This idea led the researchers to believe that the DNA structure of the organisms can be altered to bring complete change in the living organism’s character. This process is named genetic engineering. Researchers have used genetic engineering to develop some medicines and genetically modified plants and now they are using these techniques to tackle the energy crisis. Here is the list of 10 genetically engineered life forms promising a greener planet. 1. Genetically Engineered pig University of Guelph has got approval from the Canadian government to produce genetically engineered pig. These “Enviropig” pigs will act as a protector of the aquatic life by discharging ecofriendly urine and feces. The waste material of these modified pigs will contain up to 65 percent less phosphorous than the normal pigs. 2. Genetically engineered bacterium Researchers at Dartmouth’s Thayer School of Engineering worked together with Mascoma Corporation to come up with the idea of developing sustainable biofuel. The researchers named the biofuels Cellulosic Ethanol.The genetically engineered thermophilic bacterium plays an important role in converting waste into a sustainable bio fuel. 3. Genetically engineered cows An agriculture research scientist from the University of Alberta, Stephen Moore, is using the technique of genetic engineering to modify cows in such a way that will decrease the grazing needs of the cow. According to Moore, the ruminants of cow’s feed are not good for environment. Successful research will lead to the breeding of “fuel-efficient” cows in large number as Moore has already managed to breed cows that emit 25% less methane than a normal cow. 4. Sun-powered bacteria American researchers have used the technique of genetic engineering to modify bacteria in such a manner that it eat carbon dioxide to produce isobutyraldehyde. The sobutyraldehyde can be used to produce isobutanol. The new process is 10 times faster than hydrogen production. 5. Bacteria to produce plastic The credit to modify bacteria that can help in the production of plastic goes to scientists at chemical company Genomatica Inc. The scientists at this San Diego-based company have genetically engineered Escherichia coli (E. coli) to produce 1,4-Butanediol (BDO). E.coli is found in the gut of humans. The BDO produced by E.coli can help in the production of plastics, rubber, and synthetic fibers. 6. Engineered organisms to convert CO2 into bio-fuel California-based company Joule Biotechnologies has come up with a technique that uses solar converter to convert carbon dioxide into liquid biofuels. A broth of gray water, nutrients and genetically modified organisms, which were not named by the company are used to produce biofuels. 7. Engineered tobacco plants The idea to use tobacco plants to grow solar cells is the brainchild of researchers at UC Berkeley. A virus has been genetically modified by the researchers to tobacco crops and manufacture artificial chromosphores. We know that plants trap sunlight and this sunlight is turned into high-powered electrons by artificial chromosphores. 8. Genetically engineered viruses MIT researchers have developed genetically modified viruses that could make lithium-ion batteries non-toxic without affecting the performance of the battery pack. The researchers used the technique of genetic engineering to develop positive and negative ends of a battery. 9. Controversial genetics could change the composition of wood into new energy sources The co-director of North Carolina State University’s forest biotechnology group, the forest biotechnology group has come up with the idea of generating new energy by changing the composition of the wood using the technique of genetic engineering. The production of transgenic tree is a controversial thing as many experts are against it. 10. Cloning the Diesel Tree Biologist Chhandak Basu is working on his idea of cloning the gene of a tropical “diesel tree” into other plants to produce biofuels in large amount. Basu wants to re-cultivate the cloned genes in algae and weeds for mass production.

Comments Off on Alternative fuels to power our world after petroleum

Shallu Sharma: Alternative fuels Alternative fuels after petroleum The steady exhaustion of conventional energy sources have left us with acute energy resources. The way out is to generate energy from mother nature and its abundant natural endowment in various alternative forms. Alternative fuels provide choices to the users and they can set their priorities according to the convenience and abundance. Let us enrich our knowledge by learning about alternative fuels to power: 1. Hydrogen Hydrogen as alternative fuel Hydrogen as alternative fuel Hydrogen is the most abundant element in the universe. It can be produced from fossil fuels and by electrolyzing water. Hydrogen can be used as a fuel in the vehicles without producing any harmful emissions. Hydrogen is non-toxic in nature therefore, engines using hydrogen have longer life and faster pick up. Hydrogen is an eco-friendly fuel that contributes in reducing carbon pollution and serves to save environment. The only problem faced by the researchers while using hydrogen is its high cost of production and storage. Once this problem is solved, hydrogen will become the most utilizable fuel and will eradicate our dependency on petroleum. 2. Electricity Electricity as alternative fuel Electricity as alternative fuel Electric fuel is a source of energy which could be generated from easily available resources like sunlight, wind energy and even bacteria. More and more eco-friendly electric cars are being created these days and all these cars are powered by electric fuels instead of pollution creating petrol or diesel. These battery powered cars produces zero emission creating green and clean transportation system. 3. Biodiesel Biodiesel as alternative fuel Biodiesel as alternative fuel Biodiesel is another renewable fuel that is produced from vegetable oils and animal fats. Biodiesel mixed with petroleum diesel can be used to fuel diesel vehicles. The biodiesel fuel produces negligible emissions, clean burning, and is domestically produced, providing energy security and safety benefits. Engine workability is improved using Biodiesel as it provides adequate lubricity and prevents moving parts of engine from wearing permanently. 4. Solar energy Solar Energy Solar Energy an alternative fuel Solar energy is the most abundant source of energy on earth. It could be harvested in various ways to produce energy that could be used to meet daily energy needs. Basically there are three ways to harvest solar energy. First method uses solar cells known as photovoltaic cells to convert sun light directly into electricity. A square meter of solar panel is capable of generating power to light 100W bulb on a sunny day. Another technique uses solar furnaces. Solar furnaces use large number of mirrors to concentrate solar energy to a small location producing temperature as high as 33,000 degrees Celsius. This energy could be used to create electricity with the help of turbines. Next method uses Solar Towers. These towers are made above green houses which are warmed by sun. Air in the middle of the tower gets heated and moves up quickly. In doing so it generates energy by moving air turbines fitted in the tower. The most remarkable features of solar energy are its clean and pollution free properties, it can be produced in any remote area on the earth and the low maintenance required by the solar energy producing systems. 5. Wind energy Wind Energy Wind Energy alternative fuel Energy generated using wind farms is one of the purest and greenest form of energy. A wind farm consists of large number of individual wind turbines running on wind, producing substantial amount of energy that could be used to meet the rising energy demands. The unused land between the turbines in a wind farm may be used efficiently for agricultural and other similar purposes. Thus no space gets wasted in a wind farm. Globally 2 percent of power production comes from wind turbines with the capacity increasing every year.

Comments Off on How to generate green energy using wind turbines

Ankit Dahiya: Wind Turbine Wind turbine are mainly used to produce electrical energy through kinetic energy of the wind. Wind energy is one of the major sources of producing green energy in the world. Wind turbines are used for generating power from wind energy. These wind turbines actually convert the kinetic energy of the source wind into mechanical energy that in turn is converted into electrical energy using an electrical generator. Made in various sizes, these turbines can be used for various small or large commercial purposes. These turbines which are small sized can be used as a source of production of energy for running basic home appliances. This technology is in use from long period and these days the wind turbines are available in two different types; vertical-axis type in which the blades are made in vertical direction with respect to the ground and the other is horizontal axis type which is made horizontally with respect to ground. But the horizontal axis turbines are more popular than the vertical axis turbine and are widely used for energy production. Production of green energy by using wind turbines The first step for setting up a wind turbine is to find a perfect location. After this step you are almost half done in setting up your wind turbine. This is one of the basic steps as location with high wind would be more appropriate to set up a wind turbine. A technology called Aerodynamic modeling is used to calculate the average optimum tower height, control system to have a control on various devices, total number of blades, and their shapes. The basic components of a conventional wind turbine are; rotor, generator component and the physical structural support component. The rotor component is the rotating part of the wind turbine which rotates when wind is incident on them. This wind causes the movement of rotor which includes blades for the conversion of wind energy into rotational energy. The rotor component of the wind turbine costs approximately 20% of the total turbine cost. Next up is the generator component of the wind turbine that is used for the generation of power. It includes the basic components of a generator like the electrical generator, a gearbox and control electronics system. The gearbox component is primarily used to convert the low speed incoming rotation of the rotor to high speed rotation that is more applicable for power generating. The various gearbox used widely are planetary gearbox and continuously variable transmission. It accounts for 34% of the total wind turbine cost. The third component used for the generation of power through a wind turbine is the physical structural support component that provides a comfortable and strong support to the whole wind turbine tower. This includes the tower and rotor yaw mechanism. It accounts for 15% of the total wind turbine cost. The horizontal-axis turbines, which are widely used, have a rotor shaft and generator at the top of the tower. These two components are pointed toward the wind so that most of the wind energy can be utilized to produce energy. The wind energy incident on the blades of the rotor helps in rotating the blades and in turn it produces energy. The gearbox is used at this time to increase the speed of rotation of blades so that high amount of energy can be produced. The rotor is coupled with generator and when it rotates it converts the mechanical energy of the rotor to electrical energy using an electrical generator. In this way the energy is produced through a wind turbine. In United States the basic height of the wind turbine used is 80 meters that is capable of producing a large 1.5 MW of energy. The components of the wind turbine are actually very heavy and only the weight of rotor assembly weighs around 22,000 kg. While the nacelle that contains the generator component of the wind turbine weighs 52,000 kg and the concrete base weighs almost 26,000 kg. On the whole the wind turbine set up requires a huge budget and heavy devices.

Comments Off on Future Perfect: Using bacteria to enhance biofuel production

Abdul Vahid V: biofuel production from bacteria Using bacteria to enhance biofuel production What’s happening right now? No one may be doubtful of the fact that our fossil fuel sources are draining out quickly. According to some estimates, energy sources like coal and natural gases will last only 148 and 61 years respectively. All other traditional energy sources are to deplete in several years. It is high time scientists should find out some consistent methods to produce alternative fuel sources. It is here options like biofuel gain attraction among researchers and specialists. The number of people, who lead researches to explore the possibilities of biofuel, has stepped up over the years. Indeed, we can listen to some hopeful outcomes from the researchers in near future. So far, we have some optimistic information to share with you in development of various biofuel production methods. There is an advanced method of employing bacteria to generate biofuel from different sources. Go through the article to know more about the developments in the area. Trends 1. OPX Biotechnologies produce renewable fuel from the strains of E. coli bacteria based process bacteria based process for producing biofuel A Colorado-based startup firm, OPX Biotechnologies has developed an organism to convert sugar to acrylic acid using strains of E. coli. The biggest benefit of this method is that the process emits less carbon dioxide. OPX showcased its innovative technology in a pilot plant that has a 200-liter fermentation boiler. According to the OPX researchers, the green technology will help reduce gasoline consumption by more than 500,000 barrels a year. 2. Bioengineers boost bacteria’s potential to produce bio-ethanol Ethanol Biofuel Production from bacteria Biofuel Production from bacteria It is a pioneering method from biofuel researchers to produce ethanol biofuel from bacterial strain. A team of U.S. researchers has developed the technique to modify a strain of bacteria to boost up its potential to generate ethanol. The researchers used Zymomonas mobilis, a bacterium famous for its capability to produce bio-ethanol, to augment bacterial strain to generate more biofuel. The technology has received huge acceptance since it will largely help in the world’s efforts for alternative fuel options. 3. Bacteria feast on sugars and produce biofuel biofuel production from bacteria Using bacteria to enhance biofuel production Accepting the traditional way to produce biofuel may not cut the danger to the environment anymore. It is here a team of U.S. biologists has developed a process to use genetically-engineered E. coli bacteria to feast on sugars in wood chips and biomass waste. Production of biofuel this way will not raise any threat to the nature. According to the researchers, production cost is also very less in this process. The concept The very attraction behind employing bacteria to enhance biofuel production is that it won’t add into the greenhouse gases. If we follow the traditional ways to produce biofuel chances are high that it will badly hit our nature and add into the global warming threats. Moreover, production of biofuel from sugarcane or corn will lead to price increase of food items. The new technologies put forward methods to deploy bacteria to produce biofuel from food wastes and residues. The advantages As mentioned above, the biggest advantage of the new technology is that it makes no threat to the nature. In other words, the amount of carbon dioxide emitted from the process is less than 75 percent from the traditional methods. As well, popularity of the method will boost the production of biofuel. Ultimately, it will end up in the less consumption of fossil fuel, which is depleting faster these days. The impact Needless to mention innovative technologies like the production of biofuel from alternative sources is a great help for the human hood as a whole. Exhaustion of conventional fuel sources is a looming threat for human beings, whose life is largely dependent on fuel. New technologies will realize production of more biofuel that can help reduce the effect of global warming and other environmental collapses.
