NanoLight claims to be world's most efficient light bulb. The NanoLight LED’s are directly attached to a printed circuit board that is folded to resemble the stereotypical light bulb shape Until recently LED light bulb manufacturers have struggled to find a solution in the 75 to 100-watt range which successfully replaces the soon-to-be redundant, energy crunching 100 W incandescent bulb in terms of size and brightness. Three friends from the University of Toronto are the latest to offer a feasible product to match the classic 100 W bulb without compromising on electricity consumption with their proposed NanoLight LED light bulbs. Gimmy Chu, Tom Rodinger and Christian Yan of NanoLight met during a university solar car project back in 2005. With a shared enthusiasm for sustainable products they joined forces again three years ago and aim to launch three models of the Nanolight in the near future through the funding platform Kickstarter. The trio hopes their products will prove that t

E-waste Management In India The aim of this article is to spread awareness among our readers about the various issues involved in generation and management of e-waste, particularly from Indian perspective. What is e-waste? Electronic waste (e-waste) comprises waste electronics/electrical goods that are not fit for their originally intended use or have reached their end of life. This may include items such as computers, servers, mainframes, monitors, CDs, printers, scanners, copiers, calculators, fax machines, battery cells, cellular phones, transceivers, TVs, medical apparatus and electronic components besides white goods such as refrigerators and air-conditioners. E-waste contains valuable materials such as copper, silver, gold and platinum which could be processed for their recovery. you are welcome to change your personal computer, cell phone, refrigerator, or for that matter any electronic or electrical gadget, but be careful while disposing of the old one. Throwing i

Graphene from gases for new, bendable electronics. Flexible, translucent and ultrathin, layers of carbon atoms called graphene are also excellent electrical conductors that could find use in flexible computer displays, molecular electronics and new wireless communications. Making high-quality graphene sheets is usually a slow, painstaking process, but now several research groups have discovered ways to make patterned graphene circuits using techniques borrowed from microchip manufacturing, which can be scaled up for mass production. Layers of graphene — carbon atoms arranged in a chicken-wire pattern one atom thick — can be manually peeled away from the graphite in pencils using adhesive tape. In contrast, the new technique causes carbon atoms in a vapor of hydrocarbons to settle onto a nickel surface and arrange into graphene’s characteristic pattern of hexagons. Using standard chip-making techniques, circuit designs are etched into the nickel surface. As the graphene layer

The human battery: anything that achieves motion creates energy. As time passes we expect consumer goods, especially electronics, to get smaller, faster, and more powerful. Nowadays, however, much of the emphasis is on making technologies more efficient. It’s using masses of human beings as heat sources for buildings and perhaps one day capturing the kinetic energy created by cars, trucks, bicycles and pedestrians to power whole sections of cities. It is, in essence, solving our energy crisis one human at a time. And this economizing approach ­­­­­­­­­­­– to produce more from less – could have a tremendous impact on future products and brands. That’s because anything that achieves motion creates energy. IBM Distinguished Engineer Harry Kolar predicts that in the coming years, “advances in renewable energy technology could make it possible for us to draw on power generated by everything from our running shoes to the ocean’s waves.” Naturally, enslaving humans to function as energy sourc

Half-a-loaf-of-automotive-aerodynamics what is aerodynamics? Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object as defined by wikipedia. Aerodynamics of automobiles: drag: drag is a fluid dynamics term, sometimes called as air resistance or fluid resistance. It is defined as "forces that oppose the relative motion of an object through a fluid. Drag forces act in a direction opposite to the oncoming flow velocity". (wikipedia ) Shape and flow Form drag Skin friction 0% 100% ~10% ~90% ~90% ~10% 100% 0% lift: A fluid flowing past the surface of a body exerts a surface force on it. Lift is defined to be the component of this force that is perpendicular to the oncoming flow direction. It contrasts with the drag force, which is defined to be the component of the surface force parallel to the flow direction. (wikipedia ) Note: In aircrafts Lift/drag ratio is e

Human Power is the Future. Engineers have developed a device that may change the way that we power many of our smaller gadgets and devices. By using out natural body movement, they have created a small chip that will actually capture and harness that natural energy to create enough energy to power up things such as a cell phone, pacemaker and many other small devices that are electronic. The chip is actually a combination of rubber and ceramic nanoribbons. When the chip is flexed, it generates electrical energy. How will this be put to use? Think of rubber soled shoes that have this chip embedded into them and every time a step is taken, energy is created and stored. Just the normal walking around inside the office during a normal work day would be enough to keep that cell phone powered every day. An application that has pacemaker users excited is the fact that this chip could be placed in proximity of the lungs and it would create natural power for their pacemakers. Currently, the onl

Hydrogen Gas Production Doubled with New Super Bacterium. Hydrogen gas is today used primarily for manufacturing chemicals, but a bright future is predicted for it as a vehicle fuel in combination with fuel cells. In order to produce hydrogen gas in a way that is climate neutral, bacteria are added to forestry or household waste, using a method similar to biogas production. One problem with this production method is that hydrogen exchange is low, i.e. the raw materials generate little hydrogen gas. Now, for the first time, researchers have studied a newly discovered bacterium that produces twice as much hydrogen gas as the bacteria currently used. The results show how, when and why the bacterium can perform its excellent work and increase the possibilities of competitive biological production of hydrogen gas. There are three important explanations for why this bacterium, which is called Caldicellulosiruptor saccharolyticus , produces more hydrogen gas than others. One is that it has a
