The Best Online Research Apps/Sites You've Never Heard Of Is it possible to conduct research without Google? YES! In fact, it’s NECESSARY for college-level research. Google and other Internet search engines are great tools for researching the basics of any subject. The New Way Things Work "The Way Things Work is not the only book that has tried to explain modern mysteries, but it's the best. Macaulay's explanations are lucid; they are also fun. He includes visual puns, running jokes, a cast of thousands of tiny participants in on and around the machines, choirs of angels and lots of big woolly mammoths." Boston Globe "Keep the book a secret from your kids for a while and study up on the explanations of questions you're anticipating.

New Principle of Wind Generated Electricity Discovered The technology was developed by Johan Smit and Dhiradi Djairam, scientists at Delft University of Technology. A scale model of the Ewicon has been built by Mecanoo Architects and is located in front of the faculty of Electrical Engineering, Mathematics and Computer Science at the same university. At the moment, the researchers have created just a few small-scale working prototypes of the Ewicon, as the team needs more resources to build a larger model. Ewicon, which is shortage of “Electrostatic WInd Energy CONverter”, is able to generate electricity from wind energy, but not by transforming mechanical power into electrical energy. It does this by pushing charged particles through wind in a direction which is opposite of an electrical field.

MacGyver of the Day: Instructables' Christy Canida and Eric Wilh @GeicoCaveman: Because we all must conform to your standards of beauty and what is decent. @tselby: no, it just that as a gay man my standards are little higher than that of an average hippie douche. those haircuts are just esthetically hideous. that is a fact. i personally dont care if you use a flowbee and a bowl as your method of cutting hair. but are you really going to argue that either one them has a good haircut? take your pc bullshit and stick it up your ass, im making an observation as i have every right to do. so with that being said - i'll challenge you to post some links to your projects you've shared with the world - you won't and you'll just slink back to snarking on another post, here or somewhere else. i'm @GeicoCaveman: I'll agree that the PC level here, like many "blogs" on the internet, are really high. Expendable ideals for expendable people.

Tesla Model S Achieves Best Safety Rating of Any Car Ever Tested Palo Alto, CA — Independent testing by the National Highway Traffic Safety Administration (NHTSA) has awarded the Tesla Model S a 5-star safety rating, not just overall, but in every subcategory without exception. Approximately one percent of all cars tested by the federal government achieve 5 stars across the board. NHTSA does not publish a star rating above 5, however safety levels better than 5 stars are captured in the overall Vehicle Safety Score (VSS) provided to manufacturers, where the Model S achieved a new combined record of 5.4 stars. MC2 can transform into 8 different bikes There are plenty of bikes out on the market but most companies stick to the traditional design as anything off the ordinary is at risk of not being a success. The MC2 from IDSG Engineering and Trading however is a transforming bike which can be arranged into one of eight different configurations. [Image Courtesy of MC2Bike] The MC2 has been moslty shown in what is called the Cruiser mode which takes on the appearance of a tricycle/penny farthing type bike. When you look at the pedals on the front wheel in this set-up you might immediately think of fixed gear bikes, however, in this case the wheel hub of the bike comes with a planetary gear system and two brake rotors. The company behind the MC2 claim that it is the world’s first transforming bike and it was shown off at Eurobike recently.

Amazing ERO Concrete-Recycling Robot Can Erase Entire Buildings Demolition is a messy business—not only does the process require heavy machinery and produce clouds of dust, but it also results in giant piles of rubble that often head straight for the landfill. Omer Haciomeroglu, a student at Sweden’s Umeå Institute of Design has designed Ero – a robot that recycles concrete in an energy-efficient manner and separates it from rebar and other debris on the spot. The project won the 2013 International Design Excellence Award (IDEA) in the Student Designs category. Heavy machines used in demolition consume large amounts of energy in order to crush concrete walls into small pieces, not to mention that demolition processes have to be accompanied by large amounts of water sprayed onto the structures to prevent the spread of dust. Once the work is done, the rubble is transported to recycle stations where waste is separated manually.

Clothes Dryer of the Future Uses Vibrations, Not Heat Scientists at Tennessee’s Oak Ridge National Laboratory have developed a “dryer of the future” that uses high-frequency vibrations instead of heat to extract moisture from clothes. Compared with traditional tumble dryers, which can consume as much energy as a refrigerator, clothes washer, and dishwasher combined, according to the Natural Resources Defense Council, the newfangled process significantly reduces drying time and energy use. Ayyoub M. New efficient, affordable solar tech could trump fossil fuel Striking another blow to the oil and gas industries, an American solar company has developed technology that can produce super-efficient solar power that’s cheaper than fossil fuels. Rayton Solar’s new solar panel manufacturing technology uses 50 to 100 times less silicon than other technologies, cutting out large amounts of the most costly component of solar panels. The company says its patent-pending process uses just four microns worth of silicon, leaving no waste – while boosting the efficiency of their panels to 24 percent. According to the company that’s 25 percent greater than the industry standard efficiency, which currently tops out at about 15 percent. Rayton claims their patent-pending solar PV modules can be manufactured in the United States at a cost of 60 percent less than the industry average, which is based on prices from places like China where the majority of solar panels are made.

Le Reve Bleu - the Blue Dream Say the name Bugatti, and a fair number of folks will recognize it as an automobile. Fewer will know the name of Ettore Arco Isidoro Bugatti, the founder of Automobiles Ettore Bugatti, or that he, while Italian by birth and heritage, was actually French, as was his namesake company. Fewer yet will know that Bugatti was founded in 1909 in Molsheim, which, at the time, was actually a German town; (Molsheim is located in Alsace, which changed hands quite a few times back in those days). Likely next to nobody knows that Ettore Bugatti also built airplanes, actually, an airplane – One very special airplane – Le Reve Bleu – the Blue Dream. Ettore Bugatti came from an artistic family. His father designed furniture and his mother was a renowned sculptor.

MIT's groundbreaking mini fusion reactor could power the world within 10 years Engineers at MIT spend a lot of time figuring out how to make things better, faster, and often smaller. Now, powerful new magnet technology has led the way to a groundbreaking design for a small, modular fusion ARC reactor that generates the same amount of power as its larger predecessors. MIT researchers believe this new concept could be realized in as little as 10 years, and this type of power generation could be the clean, renewable energy the world has been waiting for. Nuclear fusion power plants are a dream fusion scientists have been chasing for decades, and it’s always been just out of reach. Until now, the enormous size and heat involved in a fusion reactor large enough to produce utility-scale power made projects like that very expensive. As with many things, the ability to make a fusion reactor smaller also makes it less expensive and easier to build.

12 engineering gifs for your pleasure There’s nothing like a mesmerizing looping gif to explain concepts in a simple and visual fashion. Here we present 12 gifs that explain simple processes that they probably didn’t teach you in school: 1. How ice-cream sandwiches are made via imgur | reddit/u/NTRX 2. These are probably the coolest engineering GIFs you'll ever come across The use of Automation or Automatic Control has truly revolutionized manufacturing processes. The benefits include control systems for machine operations, switching in telephone networks, steering of ships, speed control of moving vehicles, and many more applications. Some of the main benefits of using automation in manufacturing processes are the fact that they dramatically reduces labor costs, save time and energy, and also improve the quality, accuracy and precision in the manufacturing process.
