A Smarter Planet Blog 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. However, when conducting research for accredited college courses, students need to find legitimate, trustworthy resources. By now, you’ve probably noticed that we love making lists, especially when it comes to making learning less expensive (like how we’ve found online colleges that offer laptops to its students). Artcyclopedia – If you’re looking for information on artists or art movements, Artcyclopedia is a great place to begin.

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. Positively charged particles normally follow the anode, but when the wind pushes the particle away from the negative electrode, it increases its potential electrical energy that can then be collected. The wind turbine consists of a battery, inverter, HVDC (High-Voltage, Direct Current) source, pump and charging system. via: [wired.co.uk]

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." "Keep the book a secret from your kids for a while and study up on the explanations of questions you're anticipating. "The Way Things Work is a superb achievement. "This is a work of mammoth imagination, energy, and humor. "Combining the tongue-in-cheek observations of a budding prehistoric engineer with acute descriptions of the functioning of mechanical and electrical machines, Macaulay has produced a superb volume.... "An astonishing tour-de-force, three years in the making, by the architect-turned-author who has given us Cathedral and City...Large, clear, complete drawings...contain unexpected little details providing hours of enlightenment and discovery."

Pro Con Lists 3.5 Preview Web Design Blog, Tutorials and Inspiration | Web Design Ledger Instructables - Make, How To, and DIY Tesla Model S Achieves Best Safety Rating of Any Car Ever Tested | Press Releases 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. Of all vehicles tested, including every major make and model approved for sale in the United States, the Model S set a new record for the lowest likelihood of injury to occupants. While the Model S is a sedan, it also exceeded the safety score of all SUVs and minivans. The Model S has the advantage in the front of not having a large gasoline engine block, thus creating a much longer crumple zone to absorb a high speed impact.

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 pt@makezine.com @GeicoCaveman: I'll agree that the PC level here, like many "blogs" on the internet, are really high. Expendable ideals for expendable people.
