"This year we've seen molten salt power plants start to pick up steam around the world, and now the technology is heating up stateside — California just approved its first molten salt energy plant. Designed by SolarReserve, the plant uses heliostats to focus thermal energy on a power tower filled with salt, which is able to reach very high temperatures (over 1000 degrees Fahrenheit) and can hold heat for an extraordinary length of time. Heat from this reserve of molten salt can then be pumped through a steam generator to provide on-demand energy long after the sun has set."

"Have you ever wanted to catch the perfect photo with your SLR camera but couldn't time the shot just right? Photography enthusiast Matt Richardson brings us an instructional video over at Make Magazine that shows how to use some very basic breadboarding and an Arduino Nano to do some high-speed flash photography that is timed by sound instead of your finger hitting the button on the camera. He pops a balloon and smashes a wine glass to show some results. His code is available on Github, and you can find more of this sly hardware hacker on his YouTube channel."

"A 'shadow writer,' who lives on the East Coast, details how he makes a living writing papers for a custom-essay company and describes the extent of student cheating he has observed. In the course of editing his article, The Chronicle Of Higher Education reviewed correspondence he had with clients and some of the papers he had been paid to write. 'I've written toward a master's degree in cognitive psychology, a Ph.D. in sociology, and a handful of postgraduate credits in international diplomacy. I've worked on bachelor's degrees in hospitality, business administration, and accounting. I've written for courses in history, cinema, labor relations, pharmacology, theology, sports management, maritime security, airline services, sustainability, municipal budgeting, marketing, philosophy, ethics, Eastern religion, postmodern architecture, anthropology, literature, and public administration. I've attended three dozen online universities. I've completed 12 graduate theses of 50 pages or more. All for someone else.'"

"It seems the placebo effect isn't just valid on drugs. It's also a fact on elevators, offices and traffic lights. An article by Greg Ross says: 'In most elevators installed since the early 1990s, the 'close door' button has no effect. Otis Elevator engineers confirmed the fact to the Wall Street Journal in 2003. Similarly, many office thermostats are dummies, designed to give workers the illusion of control. "You just get tired of dealing with them and you screw in a cheap thermostat," said Illinois HVAC specialist Richard Dawson. "Guess what? They quit calling you." In 2004 the New York Times reported that more than 2,500 of the 3,250 "walk" buttons in New York intersections do nothing. "The city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals, even as an unwitting public continued to push on."'"
