lucidkoan writes "MIT researchers recently unveiled the world's first thin-film solar cell printed on a sheet of paper. The panel was created using a process similar to that of an inkjet printer, producing semiconductor-coated paper imbued with carbon-based dyes that give the cells an efficiency of 1.5 to 2 percent. That's not incredibly efficient, but the convenience factor makes up for it. And in the future, researchers hope that the same process used in the paper solar cells could be used to print cells on metal foil or even plastic. If they're able to gear efficiencies up to scale, the development could revolutionize the production and installation of solar panels."

greenrainbow writes "A Japanese company called Super Faith has developed a new machine that turns used adult diapers into a clean fuel source in about 24 hours. You simply place the bag of dirty diapers in the machine, and once set it motion it pulverizes, sanitizes and dries the material in the diapers and then forms it into small pellets that contain 5000 kcal of heat per kilogram and are meant to be used in biomass heating and electricity systems. Super Faith has reportedly installed two SFD systems at a hospital in Tokyo's Machida area. Each is capable of turning 700 pounds of used diapers — and everything they hold — into fuel every day."

A recent GamePro article sums up a lesson that developers and publishers have been slowly learning over the last few years: gamers don't want as much from games as they say they do. Quoting: "Conventional gaming wisdom thus far has been 'bigger, better, MORE!' It's something affirmed by the vocal minority on forums, and by the vast majority of critics that praise games for ambition and scale. The problem is, in reality its almost completely wrong. ... How do we know this? Because an increasing number of games incorporate telemetry systems that track our every action. They measure the time we play, they watch where we get stuck, and they broadcast our behavior back to the people that make the games so they can tune the experience accordingly. Every studio I've spoken to that does this, to a fault, says that many of the games they've released are far too big and far too hard for most players' behavior. As a general rule, less than five percent of a game's audience plays a title through to completion. I've had several studios tell me that their general observation is that 'more than 90 percent' of a game's audience will play it for 'just four or five hours.'"

Last April, we discussed news that video game rental service GameFly had complained to the USPS that a large quantity of their game discs were broken in transit, accusing the postal service of giving preferential treatment to more traditional DVD rental companies like Netflix. Now, just over a year later, an anonymous reader sends word that the USPS has responded with a detailed inquiry into GameFly's situation (PDF). The inquiry's 46 questions (many of which are multi-part) cover just about everything you could imagine concerning GameFly's distribution methods. Most of them are simple, yet painstaking, in a way only government agencies can manage. Here are a few of them: "What threshold does GameFly consider to be an acceptable loss/theft rate? Please provide the research that determined this rate. ... What is the transportation cost incurred by GameFly to transport its mail from each GameFly distribution center to the postal facility used by that distribution center? ... Please describe the total cost that GameFly would incur if it expanded its distribution network to sixty or one hundred twenty locations. In your answer, please itemize costs separately. ... Does the age of a gaming DVD or the number of times played have more effect on the average life cycle of a gaming DVD?"
